Mansard loft conversions are ideal if you want to maximise the space in your home. Extending your roof out into a flat roof with an almost vertical wall, they almost always require planning permission but can add significant value to your home.

Mansard loft conversions range from the cheapest installation of £51,600 (CS Construction & Conversions based in S65) to the dearest of around £58,000 (C S Roofing & Building based in S8).

While these estimates give you a good idea how much you'll pay for a mansard loft conversion, the only way to get an accurate price is to get real quotes from real builders.
