    hi all im writing a dissertation on a comparison between early 1900's and early 2000's construction quality and design, I aim to do a case study on an early 1900's 2 bed mid terrace and a late 2000's 2 bed mid terrace as I want to confirm or dispell the much over used phrase of new buildings being "flimsy" with "paper thin walls" and not being built to last etc,

    I wonder if you guys have any feelings on this and if you would be kind enough to share them with me and hopefully help me with areas of research.

    So do you think that major developers speculative houses nowadays are built to bare minimum standards and cut costs wherevere possible with prefab parts and unskilled labour with little thought to how the house will be used or do you think that we have reached a peak (so far) in building standards with quality being assured, designed to last and suit the requirments of the occupants.

    Do you think that victorian houses were thrown up with little regard to quality or safety (obviously energy wasnt considered) or that the cheapness and availability of quality materials coupled with highly skilled and motivated work force with cheap labour costs post 1900 meant that it was the pinacle of British housing quality and design.

    Had we perfected the house at around 1900 after years of improvements. The modern day terrace often has a downstairs toilet, small kitchen and 1 comunal area for eating, entertaining, living etc. Whereas most terraces post 1900 had a separate diner and lounge - does this suit the needs of modern people better than its modern predecessor?

    Do you find the original 'features' of victorian property charming or do you find them fussy and distracting. Do you find modern housing bland and souless?

    do you prefer the areas that 1900 properties were widely constructed nicer and with better street plans or do you prefer the diversity of modern estates with various housing types and cul de sac's etc.

    So are modern better or not? Have we achieved more than cavity walls, insulation and dpc's? Or is there much more than that? Why do some people prefer older terraces than new - despite no real difference in price.

    Are our builders better now or were they much more skilled 100 years ago?


    You thoughts greatefully received....
  1.  
    Some of my thoughts...

    The main difference between your 1900 terraced house and todays modern terraced house is in the nature of the construcution. Very simply, on a time line plotted between these two eras one sees a gradual shift from artisan /craftsmen construcution methods towards an ever increasing off site factory, produced, modular type of construction.

    Where once a master plasterer would carefuly prepare their lime mixes, applying several coats etc etc, now its plasterboard sheets, sacks of glue, bish bash bosh, job done, time is money.

    The same goes for any of the trades, including carpentry. Windows and doors which used to be hand made, are now factory produced and bunged in on site, sometimes with only expanding foam to hold them in.
    The point being that on the modern building site, construction methods are based on standardised materials manufactured off site and designed to save time, money and dare I say skill.
    100 years ago the situation was exactly the opposite.

    This is very general and of course not all modern houses are built like this .

    However if you want to have a clear and stark idea of present practices, just go and spend a couple of months labouring on a housing developement building site, all will become shockingly clear.

    I blame Thatcher for a lot of the present mentality.

    Not built like they used to be!

    I can confirm that as I have a socalled luxury house in Scotland
    5 large double bedroom/ jacuzzi

    build quality

    roof built wrong and not to design and poor qqulaity workmanship-installed by non-qualified carpenters.
    boiler under sized.
    hot water cylinder designed for a 3 bedroomed house to suit the under sized boiler.
    insulation - poor qulaity

    and that is not just my house

    Bot de Paille hit the nail on the head: Time is money.

    Follow the money and you'll most likely have your answer.

    The industrial revolution has been about exploiting cheap fossil fuel resources and replacing human input with cheap-energy-fuelled capital machinery. Consequence is that developers "value engineer" the hell out of everything, trying to minimise the build time and limit the variabilities of human input. This results in a general deskilling of the workforce (you don't have to pay them so much if they're not doing skilled jobs) in order that the developer can capture more of the value creation caused by replacing labour with capital machinery before they move on to the next plot. It's now all about marketing and selling a lifestyle to buyers than selling well built properties.

    Not a fully formulated dissertation for you, but just some thoughts...

    dandyclub - sorry I can't give your post the attention it deserves as I don't have the time but I thought I'd throw in a penn'orth.

    I was speaking to a colleague in the lift. She's renting a new flat at the Emirates Stadium Arsenal. It was 9C this am. She says she does't have the heating on and has never had the heating on ever and she's been there over a year.

    She moved from an ex-GLC (1940s built?) council flat. She said there she could never get warm, there was mould everywhere and she spent a fortune on laundrette tumble drying because it was pointless putting it out to dry in the winter, cos it never did.

    She's 22 - and a firm advocate of insulation!
  3.  
    Im not sure making a comparison with war/post war housing is fair. This was a special situation with thousands of homeless people requiring the mass construcution of housing, very very quickly.
    I seem to remember a figure like one third of london damaged or destroyed in the blitz, though not sure if this is correct.


    Possibly one of the rare instances when an exception can be made??

    A lot has happened in 100 years...

    Houses gained cavity walls
    We had two world wars and both had an effect on the quality of houses
    The introduction of softwood timber frame (problems and solutions).
    The introduction of the Building Regulations and the Planning system.
    An energy crisis and attempts to improve insulation.
    Global warming and attempts to improve insulation.
    Cement blocks introduced.
    The growth of large building firms and an increase in the use of factory assembly (roof trusses) and standardisation.
    Even the bricks we use have changed with many being imported from abroad.
    We still get shrinkage cracks where ceilings meet walls (why hasn't that been designed out).

    No sure all those are in the right order.

    Design may have changed but I don't think build quality has.

    We don't get those here as we use cornerbeads or tapes that are plastered over. And any painter that I know that's worth their salt also caulks all those 90o joints with flexible and paintable latex caulking for extra protection against such cracks.

    Posted By: bot de pailleThis is very general and of course not all modern houses are built like this
    That's very true. Our new house was largely built by three local craftsmen (the lead contractor was a former cabinet maker) - for the tasks they couldn't do, they subcontracted the work to other locals whom they knew and trusted. This type of situation is not unusual here where many people essentially "self build".

    Posted By: dandyclubDo you find the original 'features' of victorian property charming or do you find them fussy and distracting. Do you find modern housing bland and souless?
    I live in a Victorian-era property and like having separate formal dining and living rooms, as well as another room that functions as a communal area (commonly called a "den" over here). For the new house we built, there aren't so many demarcated rooms, but, as is typical over here, there's always a basement which can be used for all sorts of purposes. Many people have their "den" in there - even in small houses. Ours is currently unfinished, but there is plenty of potentially usable space for when we need it.

    In general, many people are "fashion" driven and aesthetics often trump functionality. It sounds like, in the UK at least, that the developers dictate the fashion and the sheeple follow. Maybe the planning system is to blame as, as far as I understand, self-build is very unusual. Over here, it's not unusual at all - even if the plans come from a catalog, the purchaser can usually customize them to their own taste and find contractors to turn them into reality. We don't have mega builders - at least, not in Quebec - I can't speak for the rest of Canada.

    What seems to happen here is that the ceiling shrinks and pulls the plaster off the wall. It's quite common to find the crack two inches down from the ceiling.

    Some sort of tape applied to the ceiling before the walls are plastered sounds ideal. Could save lots of work for self builders a year or two after moving in.

    Excellent!

    Thanks for your thoughts, it is VERY much appreciated,

    @vEHMv - I like your comments about marketing and selling a lifestyle, thats an angle i hadnt thought of actually but seems very true. The changing of what we all know is a flat to an 'apartment' is one example that immediatly springs to mind! I suppose it could also be argued that the lifetsyle of 'character' and 'period' living is one much used by estate agents and conservation bodies to promote pre WW1 housing


    @Bot de Paille & vEHMv - i think you are both right about costs and driving down skill levels to reduce wages. I think my work is heading down the path of construction now being more about making the house fit around the prefabricated parts rather than making the parts to fit the building, so to a certain degree the manufacturers are controlling the design.

    @ Cwatters - I understand what you are saying and agree that technoligically we have advanced greatly and our understanding of how buildings react to the environment has leaped forwards, but, has the standard of construction suffered? Do you think that the Victorians/Edwardians over engineered the buildings and today we just have a much more accurate understanding of what it needs and therefore do not need to go down the belt and braces route, have we seen a dumbing down of our builders work by the introduction of, for example, the b'regs telling us that all roofs must be tied down to the wall/gable?

    Why does the average layman assume walls are 'paper thin' in new build when our standards tell us that the sound transmission of a new build should be much less than a hundread year house with walls considerably thicker?

    Things like dry-lining dont give the impression of sturdy solid walls, is it all just in their mind or are we missing the point?

    @ Botdepaille - could you elaborate on your reasons for blaiming Thatcher please, I dont understand what link she has, cheers

    Dont know much about the circumstances surrounding building in the early 1900's, but modern building is dominated by a few large companies who seem to be focused on profit only. They build to absolute minimum requirements, even in the face of all we have learned over the last 100 years about how buildings work not to mention the climate change threat and energy resource depletion. It is largely these companies boardroom decisions that have lead to the decline of the trades as they have dictated how things are to be done.
    To add insult to injury they are allowed to get away with it.

    I once read/heard a comment by one of the head honchos of one of the big "building" companies in the UK in response to another comment about them being in the construction industry. He was clear that their business wasn't about building houses, it was about selling houses. Building them was one of the things they had to do to enable their real business. With this mindset, it's no surprise that they encourage the minimum build standard to get away with it rather than taking any pride in the quality of the houses.

    In my opinion, the companies are too big and there has been too little competition.

    to add to my soap box preaching - pointless as it is when speaking to the converted - how about a bit of conspiracy theory!!
    the lack of competition is due to the whole system being skewed in favour of the big companies.

    pass the soap box - ta
    Modern should be better - but it's worse because it seems to be dominated by a few big businesses and corrupt practices, in my opinion. It's the same with any trade, the big guys squeeze out the little ones, they command massive discounts from suppliers who can't survive without their business, who are forced to charge the rest of us over the odds for the same stuff. It's not about building it's about doing the bare minimum they can get away with and maximising profit. Almost anyone who hopes to stay in maintstream business and doesn't have a novel approach, ends up emulating them. It's considered weird not to want to cut corners on anything that will go unseen. I read (maybe here) about builders asking not how much to do the blower test, but how much to fake it. There are many exceptions I'm sure. That's British building today, I get the impression other countries do it much better - but why - more savvy consumers, more bespoke building, better checks and controls by BCOs - I don't know and maybe its just that the grass is always greener on the other side. step off soap box

    Interesting bit on the Transition Culture blog the other day, talking about past times in Totnes:
    his grandmother, with whom he and his mother lived, keenly moving out of an old house that was a converted cider press. “She just wanted modern. She wanted electric fires, electric cookers, electric everything. She wanted automatic this, that and everything. So we moved, at my grandmother’s insistence, from this wonderful rambling old building…. to a brand new house, typical of its time. Wooden framed, single glazed windows, open fire for a chimney which she quickly replaced with an electric fire, “I’m not having any more of that dirty coal business”. The winters were actually colder than the previous house. You’d wake up in the morning, and your breath would have condensed on the window, frozen on the inside. Inside it was cold, outside it was cold. Eventually my mother paid for an electric fire to be put in so you could reach out of the bed and turn it on. Electricity was cheap in those days”.

    http://transitionculture.org/2009/11/30/how-we-used-to-live-bringing-transition-and-oral-history-together/

    I think is is the critical bit "The winters were actually colder than the previous house". I don't know the date, but it sounds like a few decades ago. Maybe standards have improved since then, but it suggests that old isn't necessarily bad, and that the aim of new massed produced housing isn't about satisfying the needs of customers.

    In Victorian times, life and labour was cheap. They had cavity walls, but they filled the cavity with rubble and they used random and deep pieces of stone for the outer skin, incoporating through stones for strength instead of using cavity wall ties.

    They seemed to understand the need for a DPC by 1900, using slate or tar at DPC level.

    Timber for carcasing seems better than the stuff availabe today for Joinery.

    now i can't claim to have been in this game long.
    having only just completed a building apprentice ship over in NZ
    so take it with a pinch of salt.

    the standard i have been taught to think is acceptable through my qualification is a bit lame. but thats what we're taught to build - no more. it's all about the products.

    the theory materials we learn from are filled with sponsored advertising and pretty much teach you to build the prefab speculative housing that has rapidly sprouted up all over this country. then move on as fast as possible to the next one. the same company here owns the major wallboard, insulation, reinforcing steel, roofing steel, aluminium, timber treatment, formica, cement.. etc etc manufacturers and one of the larger disributions stores.

    strangely there is 1 part in about 50 units on alternative construction and zero mention of the environment in all this... anyway there's my rant
