Double Storey Extensions

  • Purpose: Suitable for adding space on both the ground and first floors, often used to expand bedrooms and living areas.
  • Property Types: Best suited for end-of-terrace, semi-detached, or detached properties with the structural capacity for a double-storey addition.
  • Permissions: Some double-storey extensions may fall under permitted development, but larger projects will need full planning permission, which we can handle on your behalf.

Loft Extension

  • Purpose: Dormer loft extensions are popular for transforming attic spaces into master bedrooms with en-suites or additional bedrooms.
  • Benefits: Maximises unused space in the attic, adding a significant amount of living area and enhancing property value.

Outbuilding

  • Purpose: Garden outbuildings can be designed as home offices, gyms, guest annexes, or storage solutions, depending on your needs.
  • Permissions: The requirements vary based on the size and location of the outbuilding. We’ll handle applications for permitted development or full planning permission as needed.

Basement Conversion

  • Purpose: Convert an underutilised basement into a bright, functional room—often used as an additional bedroom, recreation room, or even a home theatre.
  • Permissions: Basement conversions generally need planning permission due to the structural and safety requirements. This is true whether you are retrofitting a basement or using an existing one. We’ll design a layout that incorporates light and safety exit routes, aligning with council regulations.
