Depending on whether you will want us to build your house extension at the side or the rear of your existing home, and whether it will be a single storey or multiple storey, there are a couple of factors to consider in whether you will require planning permission. Please see our separate guide to planning permission for house extensions for full details.
All side, rear, single and multiple storey extensions will require building regulations approval from your local authority.
Your insurer should be made aware of the additional space within your home so that it is covered by your policy.
The average cost of building an extension in the UK is £27,000 for a single-storey rear extension measuring 20 square metres in ground floor area. A 20 square metre two-storey rear extension would usually cost in the region of £43,000. Although this is an average extension cost for the UK, extensions do vary significantly in their dimensions and specification and there are a couple of variables which will determine your total house extension cost. Please see our separate guide to the cost of house extensions for full details.
The average extension will take four weeks to complete but is dependent upon your ground conditions, access and the fixtures which are required (e.g. kitchens).
