Downside evidence grows: Modern Renders and External Wall Insulation (Cladding) are a no-no

14.6.17  Today a 27 storey block of flats went up in flames in London.  The Grenfell Tower was given cladding refurb only a year ago and would have required window replacement to fit over it.  The cladding is being looked at as possibly having facilitated this terrible fire.  Also to consider is the influence of trickle vents if open (likely) which double glazing going with cladding contains – especially to mitigate the problem of condensation that cladding can cause.  These trickle vents would allow smoke to enter flats from external cladding on fire or balcony contents on fire.

***Important new document on External Fires from BRE***

This is a very important moment to re-consider cladding.  In Dubai fires the metallic cladding facilitated fires.  Was the London cladding the same as was proposed in Hove?  Just nail-polish thin render over foam?  It certainly looks the same in media drawings, but with added decorative detailing ON TOP.  How about cavity wall insulation?  Same?  Styrofoam balls?  Building materials today are mostly foam, plastic and the cheapest ‘other’ that developers can get away with using.  See below for a set of references on cladding.  Especially recommend journalists contact surveyor/cladding expert, Joe Malone.  Have people died at Grenfell Tower because of cladding?  It increasingly looks to be the case.

13th July 2015…..The Zero Carbon dream, the Green Deal, eco-positivity and manufacturers – all have contributed to a message that says if you envelope buildings with  either silicone or acrylic rendered external wall insulation, you are freeing residents from heating bills, damp, condensation and mould.  It’s a hey presto magic silver bullet! Wah-hey!  Right?  No.  As so often happens, the downside  emerges into the expensive light of regrets…..and not before.


Increasing numbers of people complain that it is hotter inside than it is outside in warm weather and that they cannot cool their homes down by any means.  Having to install air conditioning and use fans to counteract stifling heat buildup that cannot escape at night from behind the EWI is not any kind of zero carbon dream and it means using electricity you would not otherwise have to use. Articles reporting scientists’ findings and concerns appeared recentlyin the Daily Mail and This is MoneyTrapped heat putting lives at risk was in May and Homes to ovens – lethal risk last week.  Please read them.  People in single aspect dwellings already suffer from lack of cross-ventilation and are at greatest risk in buildings clad with EWI, along with those living in high rise flats facing south.
If you wore a latex catsuit out in 25 C or 75F sunshine or wrapped yourself in a duvet coat to sit out in hot summer sunshine, wouldn’t you expect to get wet and damp inside that duvet/catsuit?  So it is with buildings.  And EWI is, effectively, a duvet; and the render over it is a seal to prevent moisture getting into it – so interior moisture can’t escape through it either.  It works both ways.  Plus, if the EWI went onto a less than perfect surface, and was not kept bone dry until over-rendered, the trapped moisture can begin to damage the building from within.

Condensation and mould

There have been too many reports of condensation and mould appearing after EWI has been put onto buildings which were previously dry and mould-free.  It forced the Scottish Government to commission a report.  This was published December 2012, exonerates EWI, speculates about installation issues and blames residents for not knowing how to use their homes.  And now BRE Wales has put out a call for evidence for as they find cause to investigate this phenomena in Wales.
There is a growing body of references and literature concerning the downside of EWI.

 Water gets its wicked way

Where water gets under the render, or the EWI/render combo are slapped onto an imperfect building some very unsightly staining occurs – tide marks even!  And the guarantee is invalidated.
At Lancaster House on the Kingsway in Hove, brickwork was rendered just a few years ago.  Not exactly waterproof render, is it!  These photos below were taken on a bright sunny 19th January 2015 day when there had been no rain for a few days.  There is no EWI under it.
These two examples above are less than successful retrofit strategies addressing whatever and looking to extend the life of these buildings.
Newbuilds, however, are prematurely ageing where EWI and silicone or acrylic type renders are used on them. Within just a few years they acquire that, je ne sais quoi, banana-republic look.
Below is the greying and stained 1-3 Vallance Gardens on the Kingsway, which is only 5-6 years old.  Cream was chosen as white was thought to look dirty too quickly.  All these self-coloured renders are sold as maintenance-free and they are not.  This nice design, right for the seafront, looks grubby.  The van Alen is the same.  And I hate to think what it costs to periodically de-stain it and bring it back to its newbuild loveliness.
That ‘poor look’ that has no cachet (but DAMN, didn’t it cost!)
And here is what is happening to the textured render at ‘My Hotel’ in Jubilee Street – again just a few years old.  Classy!
EWI can mean incurring new costs and the payback period on retrofitting with it is higher than the potential lifetime of any building. This hits council housing leaseholders hard where EWI is being forced on them.  On the Clarendon & Ellen Estate, some leaseholders gave flats back to BHCC, sold or rented their homes out and left to go who knows where – because the roughly £23,000 cost notified to each of them was not doable.  Others have ceded part of their equity to BHCC to cover the cost – all without so much as a planning application in place. 
One application has been refused, a 2nd goes to Planning on the 15th of July recommended for refusal.  Several tenants have voiced opinions about preferring the brick and one who was shown the banana CGI below got quite upset, stared in utter disbelief; but none of them is willing to put head above parapet to give this view to the council.  The council will do what it wants is their defeatist and cowed position.   Elsewhere in the city council leaseholders are resorting to law – after the fact. 
Without so much as a serious building condition survey, it is planned to remove the concrete roof, existing insulation and paving stones on top of all that to install “an overlay system” on all the towers of the Clarendon & Ellen Estate.  No other explanation or documentation.  Just “overlay system”.  An independent surveyor and the builder who commissioned him on behalf of a group of leaseholders cannot see the justification for taking out the existing roof they examined on top of Clarendon House.  Mears don’t care.  And BHCC doesn’t care.  The mast climbers are up and they are already dismantling the Conway Court roof covering.  Getting on with spending their £6.4m budget.  And this too is deterring comment on the application – especially as Mears is already up and at it and pumps out paperwork about their progress….. 
This is what is planned visually:
up to 5 june 2015 022

From This to….

Then there is the carbon capture angle.  BHCC is anxious to reduce its carbon footprint and has a roll-out programme in place to slap EWI on all its housing stock (which also requires replacing windows to put in new that will overlap and make a seal over the EWI).  The biggest carbon capture freebie going is a mature tree!  Instead of the bi-annual hard pruning of street trees so they look like loo brushes, shouldn’t street trees be allowed to branch away so they can suck up all the carbon?  Shouldn’t there be a council tree policy that treats every mature tree as carbon-capture gold dust?  Here is the science!  
There is even a YouTube video of EWI cladding falling off Stanley House, a high rise building in Bootle in the Midlands.  It happened in 2006.  Reading one of the Malone references above, it is clear attachment method really matters.  On the Clarendon & Ellen Estate the bricks are just outer decoration in front of a cavity behind which are concrete panel walls.  Glueing and bolting through all that is what the site manager says is going to be done but there is nothing in the planning application about affixing.  Reading Malone, it is clear this needs SERIOUS consideration, especially at the top of the buildings….
Progress….you have to know what is and isn’t actually ‘progress’.  And you have to do your homework and you have to look at planning applications with care.  It is so imp0rtant not to shy away from involvement with the planning process; and the fact that Mears and BHCC consider their planning applications don’t have to wait for approval (and assume there will be no interference with plans) sets a disgusting example to the public and shows absolute contempt for the planning system.  Shame on them.

NB.  Since this article was written, the planning application for EWI cladding of the Clarendon & Ellen Estate in Hove has been refused for a second time (15 July 2015).  New applications were submitted for just window/balcony doorset replacement and consented; and, in February, 2016, an application was registered for a mixture of works, including masonry repairs, with a claim in the application form that work had not begun, even though both Conway Court and Clarendon House had their masonry part-drilled out in the autumn of 2015 and left open to the elements over the high salty winds/rain-sodden winter. Instead Mears turned its attention to removing bricks and sucking out all the cavity wall insulation…go figure.

Crest Nicholson propose 150 plus flats – Lyon Close nr Wickes

Thursday, 24th August saw Crest Nicholson host a day of meetings to seek preliminary feedback about their plans to redevelop land at Lyon Close in Hove, to provide over 150 flats.  Since being chosen for King Alfred they have been having a nose around Hove and begun to look to develop in the city – not having done so before.  They have just had Mile Oak refused…..  Now comes this one!
The Lyon Close site is very private, tucked away behind Davigdor Road’s Montefiore Hospital and Hyde Housing’s offices-consented-for-redevelopment site.  Lyon Close is part of the Peacock Industrial Estate east of Wickes and the new carpet shop that recently replaced Staples on Davigdor Road. South of the site are the Hyde Housing offices, due for redevelopment into flats and the Montefiore orthopaedic hospital, each fronting Davigdor Road.

The clip is from
Those of us invited to come along, including ward cllr Jackie O’Quinn, were taken through their thinking to date, shown one layout design which the Design Review Panel did not like and a revised option.  They have had one session of pre-planning advice with BHCC planning officers and will shortly have another with intention to submit a planning application just before Christmas.  Cllr O’Quinn arrived while I was there and so I record some of her feedback to Crest Nicholson & Saville representatives (doing the application), along with my own.
Cllr O’Quinn knows the issues and constraints of dealing with Railtrack who have an Easement over this site and she is very familiar with all the battles residents have had over tree and vegetation clearances along the railway Cut in this area.  How the railway edge of this site is to be handled was much discussed, both by her and myself, with the Crest, Saville, PR team hosting this pre-design consultation meeting.
Their first layout proposal was for 4x6storey, flat roofed blocks with low-rise between them.  The Design Review Team had been negative about this, suggesting staggered heights of buildings.  Regrettably  that Panel also had uninformed suggestions of creating a sense of community here.  Both Cllr O’Quinn and myself disabused them of THAT notion being valid.  Blocks of flats do not do that.  In fact, in my experience of living in one, a heightened requirement for personal privacy dominates in a very self-protective way.
So, in response to the Design Review Panel’s feedback, the new layout of several buildings has staggered heights, including one 7 storey and one 9 storey.  It was one of only two times I reacted with an adamant “NO!”.  Whilst I quoted the Tall Building Policy (which the Saville’s rep thought negotiable & allowable!!!!), Cllr O’Quinn warned about the vociferous response to height that they could expect from the well-heeled in big houses on the opposite side of the railway Cut and surrounding streets who would go mad.  We both drew the line at 6 storeys MAX!
The revised layout had these staggered buildings but one long one right along the railway line border.  No prizes for guessing that THIS would be the affordable housing element – proposed to be a full 40% for this scheme.  Bang on top of the noise of railway traffic.  It’s not on. It’s cruelty housing and I said so.  The Crest representative defence of it was a worry.  It was my second adamant “NO!”
The debate about how to site the housing element of the scheme and whether or how much landscaping can go along the trackside area is absolutely central to how this is going to work or fail.  I suggested  that before any scheme is designed even, they need to sit down with Railtrack and work out what will and will not be cooperatively agreed by them.
Both Cllr O’Quinn and myself banged the gong for extensive greening of this site.  Cllr O’Quinn said that part of Hove was in need of more greening (thinking no doubt of the other side of the railway cut) and it would help to camouflage the buildings which people would not want to look at.  I pleaded for noise buffering tall plantings along the boundary with the Railtrack bit – evergreen and shallow-rooting perhaps, to avoid the “leaves on the line” or embankment roots and shoots issue that would get Railtrack objecting to the scheme.  Whilst it is no longer a railway siding, they RETAIN Easement rights over how the entire site is used!!!  So, really, NOTHING can go there until, and unless, they deign to give Crest some time and cooperation.  Which so far, they have not.
Noise buffering with plantings is how the length of our railway lines have been treated everywhere and there HAS to be a way to make this site less noisy when trains roar past at night and at dawn. And just triple glazing with heavy duty glass will not be a way to deal with the noise.  When trickle vents are open, noise roars through the ones where I live.  And in summer, windows need to be openable.
Within the paperwork brought to the meeting was a fabulous old photo of the site from its railway siding days.  The Sackville Trading Estate was also a railway siding and goods yard at one time.  And it has ongoing decontamination issues which were identified in planning applications a few years ago now.  This site will also have to be closely looked at for the same things.  And it will affect whether or not underground parking can be provided.  If extensive decontamination is required the area will just be capped and there would be no digging into it for underground parking basements.
Cllr O’Quinn brought up parking first and foremost.  I know from years of planning apps and planning committees that this is a major issue.  If no basement is possible….they have a problem.  All agree that car club provision would be wanted for the new estate.  I warned them the Tories are uber-keen about parking provision on a 1:1 basis!  One car space per flat.   Unlikely here!
I warned there is no significant food shopping nearby which would mean getting in cars or needing delivery space for food bought online.
One brick elevation drawing in the stack  seemed suggestive only of appearance, but had an interesting internal balcony treatment  lopping off a right angle corner.  Both myself and Cllr O’Quinn spoke about proximity of Hove Station making this an attractive potential commuter flats site.  I wondered about family housing, but it was not thought right for this site.  I still think BHCC might look to get some 3 and 4 bed flats here, though.
The site is on the Peacock Industrial Estate, and before that it was a railway siding.  An element of employment space is proposed to be incorporated in the scheme to replace the small amount of employment the present warehouses can provide.  How will BHCC feel about losing the entire site as employment-led?
In the last year or two the loss of GP surgeries became a serious issue for the city.  Across the road from this proposed redevelopment is the Charter Medical Centre which agreed to take over the 10,000 list when the Cromwell Road practice was forcibly closed by the authorities.  It CANNOT take on residents from this site too, on top of who will go into whatever Hyde eventually builds in front of this site (and another building here is going to be converted to flats too!!).  Scary, huh?  This too was brought up and discussed.  With sad faces.

A Long History of Grenfell Tower and the Lancaster West Estate

In memoriam and to introduce a blogger before whom I bow low. Municipal Dreams is an expert resource for anyone interested in housing.

Municipal Dreams

My article for iNews on the longer history of Grenfell Tower and the Lancaster West Estate to which it belonged was published yesterday. You can read it here:  A perfect storm of disadvantage: the history of Grenfell Tower.

When you visit Grenfell and the Estate, as I had to for the article, it’s hard not to feel intrusive. Taking photographs can seem even more insensitive but it seemed important to record something more than what, inevitably, have become our dominant images of Grenfell.  I hope the photographs which follow are a respectful tribute to the estate and its residents.

MATSIM don’t bother to wait for a planning decision and remove 10 yr old Plane Trees

MATSIM have two planning applications outstanding for redevelopment of he 1-3 Ellen Street semi-industial shed – these trees border the Ethel Street end

Plane trees planted by BHCC Environment Dept c2005 beside semi-industrial shed now owned by MATSIM

View south down Ethel St. to Clarendon Rd terrace in front of Livingstone Hse and showing trees and shed site MATSIM wish to redevelop

                                                                  This Week!!

Heartbreaking removal of the Plane Trees that did not have to happen and before any redevelopment consent in place


This application for demolition of 1-3 Ellen Street and erection of 4-17 storey flats and loads of offices and a single retail outlet has languished since July 2016 and remains “under consideration”.  There was no affordable housing to begin with and only a few little units suggested along the way.  But in January…..


MATSIM put in this second planning application for the 1-3 Ellen Street shed site which looks like petulance and blackmail – convert the existing shed into smaller units with a new entrance onto Ethel Street (wrongly called Ethel Road in the application Planning Statement.  IThis application was submitted in January and REMAINS under consideration.  Have they given up on the 17 storey heaped up piles of nonsense?  See the post written for 1-3 Ellen Street in August 2016 for full briefing on the megalopolis. Alongside this intention application is one looking to change use class from warehousing to offices and another to add a two-storey extension at one end.  ALL are undecided and REMAIN under consideration on the council website.
Both applications for the SAME site remain “under consideration” so why vandalise and remove the trees now?
This conversion only application is an underdevelopment in contrast with that overdevelopment.  And losing these trees is a tragedy.  A really stupid thing for MATSIM to have done.  No taste, no sense and could care less about the emerging City Plan wishes for this area.  They made a brilliant softening contribution to an ugly street scene.  And this stretch of Ethel Street, leading to the steps up to Hove Station which has seen the backs of Goldstone Villas buildings and garages converted to an avenue of small businesses on that eastern side could have been maximised and added to by MATSIM by creatively using what was already there; but no.
