Heritage Crest Build

Property Extensions

More space without moving house.

Heritage Crest Build designs and builds property extensions across Kent and the South East — double-storey brick and flint additions with new master bedrooms and en-suites, full open-plan kitchen extensions, lounge and living spaces, indoor-outdoor patio rooms and Crittall-framed sliding-door extensions.

Planning, structural design and construction all in-house. Same team from the first sketch through to the day the bifolds are signed off.
