Hi
We have had a QS report for our hoped-for extension in which the construction cost has been estimated at around £200k.
On TOP of that the QS has estimated:
- £30k for "preliminaries" - I don't understand why this is separate to the construction cost or why it's such a lot of money;
- 21k for "design reserve" - again I don't understand why this is separate or why it's so much;
- £12k for contingency;
- £52k for "professional fees" - this apparently is the architect, structural engineer, QS, and planning and building control fees;
- 3% uplift to take account of cost increases between now and the anticipated start date of the build.
All ex-VAT so the total is just shy of £375k.
This all seems like madness to me. Am I wrong to think that? The project is just a simple rectangular 2.5 storey extension totalling about 50 sq metres on the side of an end-of-terrace house, as well as a bog standard loft conversion with dormer to the existing house. We thought we'd be able to do it for £250k all in.
