I am planning an extension and have employed an architect to create the drawings. Everything has gone through planning and I am now out for quotes to local builders. However, I'm getting slightly frightened at the quotes coming back. The archiect had indicated an expected cost of around £84k but the quotes coming back are for £100k+.
Any advice on whether the quotes are reasonable or how to go about reducing them?
The extension is really in 2 parts:
The whole of the rear of the house is being extended out by 4 metres. The house is 10 metres wide and so the extension is effectivel 10m x 4m. The back wall will contain patio windows leading to a small decking area with steps down to the garden. A single 3.5m x 2.5m room will be created in the space with the rest forming an open plan Kitchen / family area. The downstairs bathroom will be extended and the quotes include installation of a shower, toilet and basin but not buying these. The building quotes include installing a kitchen but not buying the kitchen units / work surfaces. The internal stairs will be relocated and replaced.
The second part of the work is an upstairs extension. Currently it is a single large space with no Dormas. It is being extended with 3 Dormas and split into 2 bedrooms and a small bathroom. The quotes include installation of the bathroom but not buying it.
In addition to the quotes, we need to buy our own handles, light fittings and electrical switches.
