Historic homes require sensitivity, expertise and a clear understanding of how old buildings work.
HAPA Architects specialise in the renovation, extension and careful adaptation of listed buildings across Sussex, Brighton and the South Downs.
We help homeowners modernise historic properties for contemporary living while preserving the character, craftsmanship and integrity that make them special.

Set in the heart of the South Downs National Park, Black Tile House involved the full renovation of a Grade II listed home alongside a contemporary flint extension.
Traditional mathematical tiles were carefully restored, historic details matched, and the extension designed to clearly distinguish old from new — avoiding pastiche while respecting the setting.
The project was shortlisted for the Listed Property Awards 2024.

A carefully considered barn conversion that transforms a historic agricultural building into elegant ancillary accommodation and pool house facilities.
Original beams, rafters and flint walls were preserved, while new insulation, underfloor heating and an air source heat pump bring the building up to modern comfort and energy standards.
The result is a calm, characterful space that beautifully balances heritage and contemporary living.
