Mansard loft conversions in Notting Hill

Covering Notting Hill

Notting Hill sits 3 miles west of London, with Shepherd's Bush 1 miles to the south-west and Willesden 2 miles to the north-west.

Homes in London

London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.

What do you get with a mansard loft conversion?

A mansard loft conversion replaces one or both slopes of a roof with a near-vertical wall, typically at 70 degrees, with small dormer windows set into it. It creates almost a full extra storey and is common on terraced houses in towns and cities, particularly in London.
