What is Not Generally Included in meterage rates
Demolition of out buildings or part of the existing property may be required this would be considered an additional cost in these circumstances.
Professional and application fees, will vary from between 5 and 20% of the final cost of the project
Kitchens and Bathrooms can vary hugely in price and if you are building your extension to house a new bathroom or kitchen its cost will increase the meterage rate.
Steel work is not always the huge expense people think it will be, the insertion of small steels can be straight forward. However if you want to knock the corner out of your house, or want a four meter opening for bi fold doors, there will be cost implications.
VAT is something builders tend not to consider when talking about price. One of the reasons for this is that there are several VAT bandings that construction work falls under. New builds are zero rated, certain remodels fall under the 5% band. The bad news is that in all likely hood your extension will attract 20%. Beware builders who do not charge VAT. The VAT threshold as of April 2015 is £82,000 you do not need to do many extensions to hit that, and you want an experienced contractor.
So for a single storey extension that’s 4m x 6m = 24m²
24 x 1200 = £28800
Professional fees £3456
At the moment the cost of building is increasing faster than inflation. This is not because wages are increase dramatically or that companies are making more money. It is more as a result of the improving standards required by the building regulations. Among other things the thermal performance of new property has increased dramatically. Health and safety requirements have quite rightly been tighten up and are continually being tweaked. Also people’s expectations and standard of living tend to increase. More people want, underfloor heating, large bi fold doors etc.
At Doughty Construction we tend not to use meterage rates for anything other than budget costings. Even then we would consider among other things the level of finish required, what the extensions was to house, whether any demolition was required.
