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 £51,520 (Lincolnshire Building Services based in PE20) to the dearest of around £52,400 (PSP Developments based in PE6).

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.
