Such a lot of crap in this thread
There's nothing wrong with timber framed houses they are a traditional method of construction, today's are well insulated and are built quicker that's why they are cheaper, I'll poke my head out of the window and look at the 700 year old timber framed houses in my street, oh they'll rot in ten years pfft
What people compare new build to are 1930's houses which are yes solid but are damp, shrinking, cracking, need lateral restraint, poorly insulated and not very secure, only by chucking a load of money to one will you create something that is superior.
Scandinavians don't use Scandinavian timber any more most of it comes from Poland / Latvia etc
Local DIY stores are he most expensive places to buy fixtures and fittings
NHBC / Zurich guarantees are 10 or 12 years
No one builds houses out of traditional 7kn blocks any more so those saying I'll only buy a house in blockwork are actually buying 3kn thermalites which you could push a screwdriver into. 7kn blocks are only used in the structural walls of a block of flats with Bison planks in between.
MDF is not used in external walls, you probably mean sterling board
New methods I've used are
SIPS and
BECO wallform, if you think timber frame is useless have a look at them, the truth being energy efficiency is where the market want the investment, we are building at the moment passive flats in London that require one small oil filled radiator to heat the entire flat (av 100sqm) as the MVHR distributes heat around the home from your body / cooking and hot water, this is a concrete framed building so has high thermal mass staying cool in the summer, BASF PCM board in the walls to again cool in the heat and heat in the cold, 140mm SIPS external panels and K3 Kooltherm insualation and triple glazed Swedish Composite Windows. None of that lot is cheap it's all modern but if you want your blockwork walls and hefty energy bills then go for it.
