Cost of dormer loft conversions in London

Dormer loft conversions are ideal if you want to add lots of extra space to your home. Adding a box-like structure or structures to the roof, you essentially extend the roofline to add significant square footage to your loft space. This makes dormer loft conversions one of the most popular loft conversion types, as they're ideal for adding a new main bedroom with en-suite or even a self-contained living space.

In London, prices for dormer loft conversions range from £40,160 (London Design And Build based in SW1A) to £41,944 (Adamko Dry Lining London based in WC2N), but how much your conversion costs will vary depending on the size of your property, how easy access to your roof is and what you want to use the space for. 

The best way to get an accurate price is to compare quotes from extension builders in London. Post your job on HaMuch now and we'll put you in touch with available extension builders.
