What Is an Oak Framed Annexe?

An annexe is an independent living space on your property — designed for:

  • Multigenerational living (parents or grown-up children)
  • Guest accommodation
  • Short-term or holiday rental use
  • Home offices, studios or workshops with overnight capacity

Annexes can be stand-alone buildings or extensions connected to your main home. All our annexes are:

  • Individually designed for your site and intended use
  • Built to residential standards, with full insulation and heating
  • Planning-friendly, especially when replacing existing structures

Planning & Permissions
