My last post on materials is perhaps relevant to this one. Metal has pushed forward our construction techniques and what is achievable, but is it sustainable?
I suppose you must decide on what is sustainable. In a sense all buildings add to ongoing sustainability as they can be demolished releasing the land. Many of the raw materials can be used again, old bricks crushed to make modern lightweight blocks. Timber can be chipped and used in chipboard and MDF.
But to me sustainability is more than just reusing and building with efficient materials and techniques, it is building something to last in the first instance.
A modern skyscraper has a life expectancy of 75-100. I read the modern home is built with the expectation of lasting 50 years, yet we have the ability to build homes and buildings to last many generations. They could be supremely insulated and packed with eco-friendly devices and systems. A house that could be handed down generation to generation and perhaps paid for over generations making any added costs affordable. But if you where a house builder would you want that? I know white goods have a life-span factored in to them, the producers want you to buy new units on a regular basis. So why not houses too. 50 years is a slow turnover but it's better than hundreds of years. That's one factor, another is the quality of many things in today's world and in my view the lack of craftsmanship.
So I am a big fan of quality and things that last. But all too often profit and shoddy workmanship interferes with my expectations leaving me feeling a little ripped off. I appreciate everyone needs a profit but I believe if you offer a quality product that may well last decades or generations you are not only securing a lifelong customer, but a lifelong advert for your products and services. That is surely priceless. I hope that within my designs I will be able to reflect my beliefs.
Construction has changed greatly over the last few generations and we are now able to build structures unimaginable in days gone by. Precision engineering has moved forward leaps and bounds with many vast buildings constructed with tolerances of just millimeters. Materials are calculated accurately and on the whole the modern construction site if a safe place to work.All good news.
A still growing sector of construction is the reuse of buildings. Alteration and conversion to either offices or dwellings has seen some very creative uses and some in exceptional locations on many differing scales.
One big project I have been examining with interest is the rejuvenation of Battersea power station in Central London that was built throughout the early 1930's and completed in 1937. Positioned in a prime location on the banks of the River Thames at it's peak Battersea provided 1/5 of the electricity used in London. Equivalent to half the output of a modern nuclear power station. But could you ever see a modern power station of any kind turned into offices, shops and homes? Perhaps it's modern efficient design or the cost pressures of modern construction, but i cannot help thinking our predecessors tried harder with the finishing touches whatever size of project they undertook. Please check out the Battersea Power Station website to read up on current plans. It is an immense project and when completed will look amazing and it will still include one of our most iconic buildings when it might have been much easier to knock it down and start over.
