I've been noticing more and more onsite timber frame small extensions get built on the back and sides of houses and it's got me thinking is this the cheapest option or is it for better insulation specs to meet building regs. I've been undecided on what building method for my own extension later in the year or next year.
Either a double skin of block with insulation in the cavity or on site built timber frame. Looking at the price of blocks compared to the timber price for wall plates, 6x2s, structural ply, vapor barrier and exterior breathable membrane, staples, nails, vents, fire stopper, straps and the labor involved for all surely the timber frame will cost more than a double skin of block.
