How much will a building project cost me? Building design and construction costs demystified

Your project will attract costs such as net construction cost and VAT, professional fees (some consultants charge VAT, others don’t) and fees concerning statutory permission.

When it comes to the building cost, we recommend choosing builders who are VAT registered, who are either limited company or LLP and who have good reviews.

The standard VAT rate for construction works is 20%, but your project may qualify for a reduced rate e.g., 0 or 5 per cent – check for further info.

The professional fees vary. Factors affecting the costs include the size of the architectural practice, credentials of the professionals within the practice, its location, turnover and overheads as well as scope of service required by you. That’s why a good brief comes in handy.

Nothing wrong with using the service though. You need to be confident that you’ve appointed the right professional, who can deliver the service promised.

Always ask for clarity because the majority of fee proposals you get a chance to review will only state net amounts.

Statutory permission fees also apply; the two main application fees you should consider are planning and Building Control submission fees.
