Featured Project: Black Tile House, Firle

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.

Featured Project: The Barn, Sussex

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.

Planning Permission for Extensions

Many extensions require planning approval or must respond sensitively to neighbouring properties, conservation areas or design constraints.

We manage:

  • Planning applications
  • Pre-application advice
  • Design statements
  • Building regulations coordination
  • Contractor-ready technical drawings

Heritage + Modern Living

Many listed homes were never designed for modern family life.

We help sensitively introduce:

  • Better kitchens and family spaces
  • Improved circulation
  • More daylight
  • Utility / boot rooms
  • New heating systems
  • Better insulation where appropriate
  • Garden connections

Navigating Consents

Listed building work often involves multiple stakeholders including planners, conservation officers, estates or trusts.

We can manage:

  • Listed Building Consent applications
  • Planning applications
