Cost of dormer loft conversions in City Of Westminster

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 City Of Westminster, prices for dormer loft conversions range from £41,840 (Pillar Contractors Ltd based in W1K) to £41,944 (CORRECTBUILDIV.LTD based in W1B), 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.
