![]() ![]() ![]() Of course, the costs of the factory, the design and the delivery are then amortised over the whole package. How Much Difference is There in Wall System Costs? Meanwhile, when one receives a price for a timber frame construction, the price is based on the whole structure and typically includes the intermediate flooring, the internal partition walling and the roof structure, with all of it being made away from site in a factory and then brought to site for erection. The blockwork prices above don’t account for any openings or the lintels and cavity closers that each of those requires. And that’s because of the ‘horse and cow’ syndrome. If you try to do the same thing with timber frame or SIPs, you’ll come unstuck. You could amortise those costs over the whole area of the internal leaf of the cavity walling and be just about right with your answer, because any block, in any position in the home, performing any function within the structure, is going to basically cost the same.And finally there is the labour, which will average around £12.50/m2 - all of these elements add up to £36.10/m2.Then there are the extras such as mortar and wall ties, which add a further £1.60.To that, you have to add £12/m2 for the insulation in order to achieve the minimum U value.So one m2 of blockwork equals 10 blocks at a cost of, say, £10*, although you could do better.The cost of blockwork (masonry) for the internal skin is easy to establish, although it must also include the cost of insulation to allow for any meaningful comparisons. Trying to Compare Labour and Materials Costs Get a quote for your timber frame project.Trying to compare the costs on a like-for-like basis is a bit like comparing a horse with a cow - they’ve both got four legs and are covered in fur, but that’s where the similarities end. And what are the costs relative to each other? What are the likely costs you can expect per m2 of walling? So, the final decision may well come down to cost.
