How Much Does a Rear Extension Cost?
Multiple variables can affect the cost of a house extension project. These can include whether you own a terraced, semi-detached or detached house, as well as the size and roof type of your desired extension. For instance, a 3m x 3m flat roof rear extension has an estimated cost of £60,000.
We look to provide accurate cost projections from the outset and will be transparent about any additional costs. As part of this, we’ve created a clear and simple extension cost calculator – which includes 3D models of how your chosen extension would look.
All of our estimated costs for extensions include building work, plumbing, electricity, glazing, external doors and applicable VAT.
