What does a house extension in London cost?

The cost of a new house extension in London varies on a few factors. The main considerations are reliant on the planning authority, your property, your tastes and the scale of the project you would like. We have found as a guide side return house extensions are generally cheaper than a single storey house extension. Also, both of these are less expensive than the larger wraparound and double-storey house extensions. We always look for the best value in both the materials and hours we work to maintain the managed budget of the project making sure there are no hidden costs or surprises. We have found this approach results in the best house extension for the client leaving them much more satisfied and willing to recommend our services.
