Extension Cost
Extensions can vary greatly in shape, size and therefore budget. Whether you are planning a simple pitched roof extension or a larger project, costs can start to add up very quickly.
Velux offer advice on typical extension costs, which can help you gain an approximation of the build cost: -
'A basic single storey extension would typically cost around £1,000 per square metre but it could be up to £1,600 or more for a more premium two storey extension.
So a 3 x 5 metre extension would cost from £15,000 and from £50,000 for a two storey extension. These costs are just to create a room, they would not typically include the cost of a kitchen or bathroom.
This average cost should cover design through to decorating of standard rooms, but it is worth having a 10-15% contingency to cover unexpected costs.'
