This depends largely on the size and complexity:

The bigger the floor area = the more expensive.

The cheapest option is the classic loft conversion in mid terraced house with back dormer.

Taking a step up in price, the next option is a loft conversion in semi-detached or detached houses – with hip to gable and back dormer.


A ballpark figure for this in London (zones 2, 3 and 4), would be somewhere in the vicinity of £1600 p/m2 to £2000 p/m2.

There is so many considerations: the complexity of the roof structure, the logistics of the project and the area of London that the home is located in (the closer to zone 1 your home is, the more expensive it is because of the logistics and restrictions).
