Hi Chaps,
All really interesting point raised above! My wife and I are just about to build our "dream home" here in cyprus and as I'm kind of in the industry, I've been taking quite an active interest in the techniques employed here. The recent move towards steel frame building systems is, from a design point of view, a real breath of fresh air. Not only from an asthetic point of view but from enviromental and cost points also.
Astheticaly, the potential delivered by incorporating steel and timber in a project can be unparalleled.
Economicaly, steel and timber (S+T) V's concrete (C), to me at least looks alittle one sided.
1. S+T construction time reduced compared to C = reduced labour time = less pounds spent over the life of the building
2. With S+T, the quality of the materials is more controlable when compared to C (anyone spotted a crumbling, scarred, concrete building here if cyprus?) so therefore, if properly selected and installed at the design and build stages, will give fewer head aches later in life. = less pounds spent over the life of the building
3. The flexability, with modification in mind, of a S+T structure outstrips a C structure with ease. The removal/modification of an internal wall within a C structure not only requires specialist equipment but will also require specialits Knowledge. The alternative in a S+T structure can be accomplished with a regular hammer and saw and a bit of DIY knowledge. = less pounds spent over the life of the building
4. Its HOT here in the summer, resulting in alot of A/C use = £££££££. A lack of a cheap heating fuel (natural piped gas) also means high bills throughout the winter months for heating = £££££££. The insulation values of concrete are a joke. The material is slow to react to its environment, but when it does it takes an age to reverse the process. In other words, it HOLDS heat in the summer, meaning hot buildings inside and out 24/7. But in the winter, when the sun is far less intense, the material keeps out what little natural heat is avaliable. When compared to modern, hollow fibre, laminated, insulation materials, concrete sucks. The knock on effect of these insulation issues on A/C (electricity) and heating (bottled gas - kerosine) bills will, over the life of the building, be an hugh reduction.
When I weigh up the reduction in costs over the whole life of the buiding, and the asthetic potential these alternative technologies offer, I can't really see a future for the, now established, concrete structure. I know we'll be doing everything possible to embrace this potential and as a consequence be producing not only a dynamic home but also a responsible piece of architecture.
Peace out
