Zero carbon homes are very much on-topic with the COP26 summit approaching in November, but to date rather more discussion has been around standards for newbuilds, downplaying the fact that by most measures 70-80% of the planned “net zero homes of 2050” are already built, 9-inch solid walls, warts and all.  “Decarbonising” them is now exercising government, councils, the RIBA and industry at many levels.

UK Domestic energy

You’ll probably have heard of plans to eliminate natural gas boilers by 2025 – certainly in newbuilds – but my house and yours won’t be so far behind.  Domestic energy use represents about 27% of UK energy consumption, with 85% of that apparently used for heating & hot water – as significant in climate effect as the usual suspects – cars and planes.

Brian’s home in Hammersmith

You may also be familiar with Tom Pakenham’s Passivhaus in Lena Gardens W6 from a few years ago, which sets a formidable standard for whole-house renovation with huge attention to detail to achieve the required standard.

But what if you took an existing Edwardian terraced family home in 2021, and made it zero carbon while living in it, but without gutting the interior, or adding 100+mm of hard insulation to the inside of all the external walls, ripping up the floors to insulate them, and possibly compromising or losing some of the period features we appreciate?  This is what our member Brian Thresh is doing – you may have seen him present the project at London Climate Action week in June.  He shows that it can be less intrusive than we might fear.

Let’s be honest for a moment, there are only so many builders in the world, and so many hours in the day, there is little practical chance of all the country’s millions of homes being laboriously superinsulated in the next few years – after all we’ve been talking about insulation for 40+ years already.  Brian expects to be able to demonstrate that his home is zero carbon, once the annual numbers roll in, through the combination of:

• Replacement of a gas boiler with a substantial 12kW air-source heat-pump
• 6.6kW of solar cells
• Battery storage
• A green & flexible electricity tariff, using a smartmeter

There’s an interesting tension here between expenditure on craftsmanship – a well designed and precisely executed complete refurbishment often with specialist materials – the Passivhaus – and the retrofit of a period home using modern mass-produced technology to achieve a similar net result, but with significantly less upheaval. 

It seems likely that the latter will prevail for the majority because of the numbers described above, with as much of the former as is practicable on the existing housing stock, but how do the finances and carbon footprint compare: Conversion / Running / Whole life?  Much of the public discussion is around carbon, and saving on everyday bills; rather less – a lot less – on Total Cost of Ownership, or Net Present Cost, important for those with shallower pockets. As Brian says, this stuff doesn’t come cheap at the moment.  It will be instructive to assess and compare over the years to come, particularly as technology improves, such that an optimised mix of solutions can be provided for each domestic setting.  Solar cells have already improved significantly, but you may not have owned any yet !

Her Majesty’s Government has decided that Gigabit broadband (FTTP) will help overcome recent economic woes, bridge the digital divide, and level up, and has declared £5 billion public funding for the first million homes and businesses. Initially, it correctly prioritises those most in need – often in rural or semi-rural locations – but at £5000 a pop, it needs to be worth it. Time to look closer to home, and see how this relates to Hammersmith – and our conservation areas – if and when it’s promoted widely here.  Some green markings have appeared adjacent to “Post Office” manholes hereabouts, so this may be sooner rather than later. 

You’ll doubtless know that so-called “fibre broadband” is already here – but what might “Fibre To The Premises” (FTTP) mean – and should you opt for it ?  Below, we look at the implications for you and the streetscape, the technologies being deployed, and, by running the numbers, show that provided you and the Telcos are doing the right thing – several of which are mentioned – your home would be hard pressed to need the virtues of FTTP for a good many years to come – if ever.

The slowest 20% get 17M, the average 56.7M, and the top 20% get 150M

Hammersmith FTTC Broadband Cabinets

Recent street markings

Currently if you have “fibre” and aren’t on Virgin, you’re unlikely to have FTTP, you probably have fibre to a green cabinet less than a few hundred metres away, known as “Fibre To The Cabinet” (FTTC). Then, most often, the familiar phone wires, but somewhat shorter than before, which, with some updated tech in the green box and your home router, yields a big speed-up.

Local Broadband map (Thinkbroadband)

Here in Hammersmith, as one of the denser areas of London, we’re quite well served for broadband, with one or two known not-spots (the Western side of St. Peters Square being one, where our affiliate SPRA is exploring FTTP provision), but generally above London average speeds   Published stats show that the slowest 20% get 17M, the average is 56.7M, and the top 20% get 150M.  That suggests most are already on FTTC – or better.  Several companies are now offering FTTP, Openreach (BT) being just one.

Openreach fibre digging [perhaps your front garden?]

Prompting this article, your correspondent recently sat in on an IET Zoom presentation “Holes & poles : fibre to the home”, exciting stuff if you’re into that kind of thing. The clear message was that the industry has managed to wring out as much as it can from the ancient pair of copper wires that provide landline phones – now rarely used – and diggers are needed for what comes next.

There’s been a substantial discussion about the problematic last few metres from your garden wall or gate to front door. In fact the last 5-10m – never mind the last mile – is often the biggest hurdle, as we discuss later.  Logistical, cost and maintenance reasons mean wireless is ruled out, and, as the existing wires have had it, digging up the garden is likely if there are no usable ducts, followed by new holes in the front wall for a fibre “cable” and boxes on the wall.  Fortunately fibre being fibre, it’s completely safe, and the consequences of an errant garden fork are inconvenient rather than dangerous, so it need not be buried as deep as main services.

Would it be transformative locally ? 

Changing Rooms [BBC]

So-called property porn continues to make up a good percentage of the TV schedules 25 years after Changing Rooms started Building the Dream in a Location, Location, Location for The Poshest Sleepover in Millionaires’ Mansions, then over to The Great Interior Design Challenge, creating some Grand Designs, and moving on to daytime TV with rather lower budgets and more prosaic ambitions with House Doctor and Homes under the Hammer. 

More than one of these shows is approaching its silver anniversary, and you’re sure to have seen many of them – perhaps the daytime offerings too – and possibly even been addicted to one or two ?

In a roundabout way, they’re all selling the story that rising house prices are a Good Thing. The recent publication of the new London Plan ahead of the delayed Mayoral Election this week, presents a good opportunity to take the long view of the property market, and test this hypothesis in the real world.

Over the last two decades, there has been a 46% increase in the number of young people aged 20-34 living with their parents ^🔗

The evidence from first-time buyers is that spiralling prices are not such a good idea, especially post-COVID.  Excluded from markets such as our own local one, where one bedroom flats start around £250k, younger people have wondered how they’ll get on the mythical ‘property ladder’ for a while now.  Having been locked-down for much of the last year, they may be further destined to stay at home with mum’n’dad for the foreseeable, their best hope of ‘moving out’ may be to convert the garage to put a door between parents and the resultant substandard bedsit, or take a government help-to-buy mortgage – one that possibly helps stoke prices more than helps make housing affordable.  A poor show all round.

Housing Completions 2020 (MHCLG)

Classic economic theory says that rising prices stimulate the economy and increase house builder’s appetite to build.  The statistics don’t bear this out, with completions only just approaching the levels of 15-20 years ago, having been in the doldrums through periods of huge price inflation (with the real possibility of correlation), London being a particular “white spot” despite the highest price rises.  Hereabouts there are many factors at play, land availability being just one of them; the theory is too simplistic.

And what of this cash – where does it come from ?  From not spending in local shops and hospitality, or just adding to a debt mountain.  Neither are good for the real economy, locking away income for the foreseeable, and once on the ladder, the next step involves an increasing gap as prices rise, so any increased disposable income is – disposed of.  Best start saving now, or better move up quickly, perhaps by taking on an uncomfortable level of debt, before the price gets out of reach.

There remains a widespread assumption that existing homeowners subscribe to the benefits of rising prices.  Pragmatic Marxists might even tell you that releasing equity is a way to feedback escalating values to the proletariat (that’s your children, by the way).  But older voters (always sought after, unlike Auntie or marketers, forever chasing the young – discuss),  may soon get tired of their children still at home in their 30’s and even 40’s in London, as the direct effect of rising prices, and may start voting otherwise.  With the equivalent escalation of the average age of moving out, parents may become too old themselves, and disinclined to move at the time they might be able to release equity, and enjoy it.  Taking on what looks & feels like debt, in the form of equity release, probably having spent many years paying down a mortgage, may also be a bitter & alien pill, albeit perhaps a sensible one – for an economist.

Median London House Prices 1995-2020, sorted by 1995 price (ONS)

Hammersmith has the 5th highest median house prices in London.  It’s slipped one place since 1995, the graph adjacent is sorted by 1995 prices, when it was 4th, which may surprise you. 1995 prices are shown as the tiny blue bars.

Whatever nuances there are between H&F and anywhere else in town, property inflation has been huge in absolute terms, as shown in the second graphic, and much greater than elsewhere in the UK. H&F is middle of the range at 700%, explaining its 1 place fall in the above race, but the lowest priced boroughs in 1995, such as Hackney and Newham have seen the largest rises in a rather misplaced levelling-up exercise, many would call gentrification. Examine the demographics, and you’ll see the volume of younger people who have moved to those places on an affordability basis, if no other.  By contrast, average incomes have doubled in the same period but have been static in inflation-adjusted terms, meaning housing is 350% of the cost 25 years ago (c.f. ratios below), although interest rates are a lot lower if you’re borrowing the money. If you’d been what used to be called prudent – and saved for it – bad luck. Prudence was made homeless a while ago.

Percentage rise in London property by borough (ONS)

Our elders tell us that sky-high London property prices were ever so.  In the 50’s and 60’s, newbuilds were cheaper than period properties; in the age of the Space Race and (if only they’d known it) mid-century modernism, bright shiny and new was still less popular than ‘period’, and while affordability continued to decline, property aspirations remained as conservative and static as life’s DNA, a fact confirmed in the government’s recent Design Guide.

Open House has celebrated London’s amazing architecture for the last thirty years, starting just two years after our own Awards. There’s always been an eclectic selection of Hammersmith buildings in Open House, featuring some of our Award Winners over the years. Open House 2021 is scheduled for 4th and 5th of September.

Open House includes public buildings that everyone knows. It encourages private owners who are proud of the architecture or design features of their homes to open-up too. The festival is a unique opportunity to visit private residences and gardens in London, usually closed to the public – there are architectural gems hidden inside people’s own houses.

Open House would be delighted if Hammersmith Society members, supporters, their friends and contacts could suggest buildings they know that would be worth visiting. Open House can make the initial contact, even better if you already know and can pass on details.

Open House can arrange for people to gather outside as appropriate. We all hope that Covid-19 guidelines should have relaxed enough later this year to allow indoor gatherings without too many restrictions. Open House will produce guidelines covering the number of guests, mask-wearing, social distancing etc. that apply as appropriate at the time. They can discuss what works best and how to make safe arrangements.

If you would like to open your home during this year’s festival or make a suggestion for another building, Open House would be delighted to hear from you.  West London Open House volunteers can provide detailed information about taking part, contacts are:

Garages are an endangered species, locally and across London. Where once council flats would have had rows of garages below – often beloved of British spy and detective dramas where exclusively bad stuff happens – new developments are mandated not only to have bicycle storage, but also to be car-free, meaning garage-free too.

Free-standing garages and similar small industrial buildings are being demolished for housing, and as we’ve experienced locally, offices too.

The car is next on the endangered species of course, and current bogeyman of every level of government and social media alike.  One can only wonder when the car is completely green, producing no emissions – tailpipe or otherwise – running on tyres made of waste plastic designed to shed no particulate matter, what will the Twitterati and government have to berate us old dinosaurs with?  Don’t laugh – it’s only a decade or so away.

Lest we disappear down that rabbit hole, let’s focus on garages, and why they might be important for a range of socio-economic reasons, not as just car storage, which few ever used them for anyway. The site pictured above is from our 2012 collection of 50 favourite places, and true to form, was redeveloped soon after and became the location of a Nancye Goulden Award of 2015 – with not a garage in sight.

We are reminded by last week’s Last Word that Sidney Alford, the maverick explosives expert who created methods of defusing the terrorist’s preferred weapon – the Improvised Explosive Device – started in a garage. Locally, Shepherds Bush, to quote our follower @sbcalling …nowhere else on the planet has a richer history of rock & roll, TV, film and pop culture than Shepherd’s Bush, White City & Hammersmith, and where the NME has claimed one rock star to every 1,222 of the population, may have significantly benefited from garages.  Many an act has started in one, often for practice, away from others, making as much noise as they like, there’s a plethora of terminology relating to garage bands, a garage rock genre and so-on.  It certainly worked out for locals The Who, punk icons The Clash (Garageland) and the maverick Sex Pistols, with Danny Boyle’s new drama Pistol filmed last week in The Cross Keys, 45 years on.  Not much more than a glorified garage at the time, the laundry behind the 2009 award-winning 22 St Peter’s Square, AKA Island Studios, became rather significant to a huge swathe of the music industry in the 1960’s and 1970’s as Chris Blackwell’s Island Records.

Maybe no longer to your taste, but while pondering a misspent youth fixing cars in parent’s garages, including a less-fondly remembered side-line of garage rock, think of the economic benefits of garages:

Steve Jobs Garage

• Apple Inc., was started by Steves – Jobs and Wozniak – in a garage. Now worth $2,100,000,000,000 – the most valuable company in the World.
• Jeff Bezos started Amazon in his garage, Now worth $1,700,000,000,000 – the second most valuable company in the World.
• Bill Gates and Paul Allen started Microsoft in a garage, close behind at $1,600,000,000,000.
• Larry Page and Sergey Brin started Google in a garage, now worth $1,000,000,000,000.
• Bill Hewlett and David Packard started their enterprise in a modest garage at 367 Addison Avenue, Palo Alto – now worth $9,000,000,000.  It’s clearly worth only $9 Billion, because it was only a single garage, though Walt Disney did OK from his single garage too.

  Sipsmith Distillery: 27 Nasmyth St [Photo: Horton & Garton]

  Proving that being in the USA and the world of technology isn’t a pre-requisite, Brewdog is a recent Scottish garage success, now valued at nearly £2,000,000,000. They even have a bar in the aforementioned ‘Bush.

• Finally, and a lot closer to home, the now well-known Sipsmith gin distillery only started in 2009 in a modest 500 sq.ft. garage in Nasmyth Street W6, and was sold for £50M just 7 years later. There are differing views around early sales, but the relative numbers above tell their story.

Planning for the future

In March of this year the government promised legislation to improve the supply of new homes, including legislation on building safety, rental reform, social housing – and an update to the planning system.

Following this, a government White Paper Planning for the Future proposed very significant changes to the planning process for public consultation which closed last week.

Changes to the planning procedure

At present, LBHF planning applications are assessed against the development policies in the LBHF Local Plan, in the London Plan, and in the government NPPF (National Planning Policy Framework). The White Paper proposes a new approach:  a new form of Local Plan, replacing the current format of more abstract policy guidance, by a format with a prescriptive system of development rules and a design code. The Local Plan would also include borough zone plans, which would identify three categories of development:

1. Growth areas where ‘substantial development’ would be suitable (similar, we suggest, to Earls Court, Old Oak Common etc)
2. Renewal areas such as existing built areas where development is encouraged (Hammersmith Town Centre, for example)
3. Protected areas like conservation and heritage areas, green belt and parkland.

Planning zones

In Growth and Renewal areas, proposals which are compliant with the Local Plan in height, use-type etc, and compliant with the government NPPF rules, would be effectively guaranteed an automatic outline planning consent, providing a level of certainty in site purchase values. At the next stage, a full planning application,  with detailed proposals, would be granted consent if the proposals comply with the more detailed rules and design codes of the Local Plan.

Community involvement

Public consultation in the planning process would be limited to the stage when the new Local Plan is put together by the local authority: community involvement would be excluded from full planning application stage, because (it is argued)  the application would be assessed against rules which have already been agreed through public consultation.

The intention is to establish a clear set of planning rules, which are in line with government policy, and have been agreed through community consultation; armed with these certainties applications would avoid the ambiguities of policy interpretation and community objection which (it is said) can delay the full planning application stage.

Design codes

CreateStreets – Bonnington Square

To illustrate examples of acceptable design and styling, and to provide a basis of resolution of design disagreements, Design Codes would form part of the Local Plan, and would be reviewed through public consultation when the new Local Plan is being put together. Design codes would be coordinated with the government’s National Design Guide, itself heavily influenced by the CreateStreets campaign and to the emerging National Model Design Code. To help the process, a chief officer for design and place-making would be appointed within each local authority.

Health scares, 18 metre masts, autonomous vehicles, economic recovery, critical national infrastructure, Huawei… It’s a long list.

2020/01852/TEL56: Rylett Road / John Betts House: 5G proposed mast and cabinets

In Hammersmith we’ve started to see planning notices for 5G base stations, ironically mostly from the company named Three, and yes, since you ask, they are using Huawei.

From the Society’s perspective, our concerns centre on the mast height, positioning, and the associated, rather retro, street clutter.  There’s some further reading at the foot of the article, but first, to get some perspective, let’s get our terminology clear, review the most prevalent public concerns and take quite a hard look at the benefits – both real and more far-fetched.

The most widely used 5G band in the UK will be 3.6GHz…
…5G is just as safe as 4G, 3G and GSM.
– Institution of Engineering and Technology

A quick canter through some confusing G’s

1G to 5G phones

Here 1G means ‘First Generation’ AKA Analogue ‘brick’ phones of the 1980’s, 2G (AKA ‘GSM’ or ‘Global System for Mobile Communications’), a typical Nokia from the late 1990’s, 3G, the first phones with really usable Internet connections, and today’s 4G, typified by a smartphone – Apple or Android. There was even a 2.5G and we mention 4.5G later.

The gifts of Heinrich Hertz, or a billion of them, come in the form of a Gigahertz (GHz), the frequency a thousand times the Megahertz we’ve had since VHF FM radio days.  1G to 4G phones have used various radio frequencies over the years, depending on operator and country, from 800MHz up to 2.6GHz, but the operating frequency used doesn’t directly affect the data speed as far as the user is concerned.  WiFi is sometimes confusingly termed 2.4G or ‘2.4 Gig’ or ‘5 Gig’, referring to bands – 2.4GHz (the same frequency as a microwave oven but a minuscule fraction of the power) and 5GHz: a less congested, shorter range band that has nothing to do with 5G: 5th generation mobile technology.

In the digital world we similarly have Megabits describing the speed of received data – whatever the technology that delivered it – and the Gigabit of your scribe’s home, and likely your office’s high speed Ethernet wired network. We won’t discuss the many flavours of WiFi on top of the frequency bands mentioned: A, B, G, N AC, AX… a story seemingly involving yet another G, until WiFi leapfrogs 5G by changing it’s letters to numbers, becoming WiFi 4, 5, and 6, and in future extending into a new 6GHz band.  That’s the GG’s corralled 🐴

The most popular 5G band, 3.6 GHz, is slightly higher than current ranges, the implication may be more base stations as range is slightly reduced, but other bands may be used to compensate. The 700MHz band for example, cleared in June this year (responsible for the loss of several HD TV channels from Crystal Palace), has yet to be auctioned off, but is earmarked by OFCOM for 5G.

Mobile emissions

If you are at all concerned about health effects, first check and understand the implications of the SAR value for your existing 2G/3G/4G phone, which have been published by manufacturers since the days of 2G when such concerns first arose – or better, stop using it now !

Unfortunately in addition to the above health concerns, the 5G cause has been muddied, and probably harmed by overzealous marketing, too many G’s and spurious claimed benefits – we prefer to keep to the tried-and-trusted recipe of ‘more & faster’, on which it certainly will deliver. 

Arboricultural Association suggested tag

Twenty-Twenty was named the “Year of the Tree” by the Tree Council, and moments before lockdown, in Davos the World Economic Forum announced the creation of the One Trillion Tree Initiative, following on from the UN Billion Tree Campaign of 2006.  We’re hoping that H&F Council and residents will take the opportunity to participate.

In contrast, while Sheffield is normally noted for heavy industry, recently it became notorious for a rather different kind: the Sheffield Chainsaw Massacre seemingly more for the convenience of the PFI road maintenance contractor than for the public good, under a plan euphemistically called “Streets Ahead”.  The before and after shots are alarming. Furthermore, Sheffield Council has been found to have misled residents over the state of some trees.

King St. tree felling 2019

Here in Hammersmith, we recently praised the council’s street tree planting programme, particularly in the North of the borough, and the associated guerrilla gardening was nominated for an award in 2018.  In 2019 however, tree fortunes reversed somewhat, and we had our own mini chainsaw massacre, where a number of street trees were removed by council contractors without notice.

Four were removed in a day at the West end of King Street. A mature tree outside the Sainsburys local was clearly dead, two were young but had died, apparently of neglect, and the 4th (pictured in the background) was partly diseased.  The removal on safety grounds is obviously an overriding consideration, however the job was half-done, and nearly a year on, ugly and potentially hazardous metre-high stumps remain littering our pavements, not just in King St. but elsewhere in the borough.  We have contacted the council’s arboricultural officer for comment on more than one occasion – so far without response. 

Update April 2021 – it took a couple of years – but the good news is that trees have now been replaced by a new Plane and a Magnolia. Now let’s see if we can get to work on those tree pits…

Heathrow Expansion was temporarily derailed by the Judicial Review (JR) in February, ruling the Airports National Policy (ANPS) illegal through its non-compliance with the existing UK Climate Change Act, and by extension, the Heathrow expansion plans that relied on it. By law, the Climate Change Act commits the UK government to reducing greenhouse gas emissions by at least 100% of 1990 levels (net zero) by 2050.

Heathrow expansion 2019

There have been many setbacks to the Airport’s expansion plans over the years from Terminal 5 onwards: claims that several top politicians would stop expansion, elongated planning enquiries, and many anti-expansion campaigns, but like the addict it appears to be, suffering Compulsive Shopping Disorder, Heathrow Airport Limited (HAL) keeps coming back for just one more hit, claiming that it will then be satisfied.  Like it’s maniacal namesake in Stanley Kubrick’s epic 2001 – a Space Odyssey, to accept this would be to seriously misjudge the machine.

HAL’s public response to the JR is “10,000 quality apprenticeships by 2030, New Routes and 180,000 new Jobs”, plus the inevitable appeal against the judgement.  While new routes could be created easily with a new runway, they could also be created by displacing cargo and short-haul flights onto greener options, such as rail or electric vehicles (remembering that Heathrow is actually the UK’s largest cargo destination, with 1.8 million tons in 2018: up 20%, matching passenger volume increases since T5 opened).  The other two claims stretch credibility beyond reason, given that Heathrow currently employs 76,000, the expansion would represent a more than doubling in size.  Or perhaps that gives a clue as to the full plan ? 

Heathrow doesn’t appear to be addressing the issues that most of us care about – the effect on the environment, surface transport, and the lives of residents in large parts of the South-East – all the more so having recently become used to not being woken at or before 6AM with fewer flights during the Coronavirus pandemic; Heathrow has temporarily reduced to single runway operation.   In the new Greta-inspired world, HAL makes additional claims regarding sustainability, but it again stretches reason that the discredited greenwash baked into last year’s consultation could have been warmed over sufficiently to pass muster this time round.

Committee and several members attended the recent Climate Change event at the Lyric to hear what the recently formed commission has been discussing, and to provide input.  Sian Alexander, the Director of the Lyric, opened the meeting making the following points:

• The H&F commission is a residents’ working group engaged in a ‘public facing campaign’.
• The Commission started in 2019 and is one of a number of a H&F Residents’ Commissions.
• The Commission is chaired of local architect Paul Beaty-Pownall, and consists of twelve local members.
• Its purpose is to advise and help H&F Council achieve zero carbon emissions by 2030.
• Its first formal meeting took place in December 2019.
• We all need to be prepared for major changes.

Fehinti Balogun

We were then presented with a personal story of the effects of climate change from actor Fehinti Balogun, making an informative and entertaining presentation. He touched on how climate change affects not only himself but his wider family here and abroad, highlighting that the issue is about eco, not ego. He’s been giving a similar presentation to schools in recent months.

He noted that the Commission is believed to only need 3.5% direct support from the population for success to be guaranteed by influencing all those connected.

Paul Beaty-Pownall

Paul Beaty-Pownall summed up and introduced the workshop sessions that followed. The audience were invited to participate and circulate through four separate discussion groups in order to gain ideas and recommendations from the participants.

We hope to see the report from the commission in the coming months to inform the Council’s progress in accelerating our local responses to Climate Change.

To visualise the extent of the problem, the UK’s current emissions of thousands of tonnes of CO₂ per hour caused by electricity generation can be seen here
