What is a Side Return Extension?

  • Enhanced Natural Light: Incorporate skylights or glazed roofs to brighten interiors.

Basements

In order to build a basement, you underpin the existing masonry wall or form a retaining wall in the garden to the desired depth of the basement. Once the building above and garden around is stable, the main area is excavated down and a new concrete slab is poured. The concrete box is then wrapped in waterproof membrane and a pump system is installed. Ready for fit out.

Please see our basement FAQs below:

Basements FAQs

  •  Often, side return extensions fall under permitted development rights. However, if your project involves a wrap-around extension or is in a conservation area, planning permission may be required. Our partner firm, Malone + Pike Architects, can assist with the planning process.

  •  Typically, a side return extension takes between four to six months, depending on the project's complexity.

  • Yes, a structural engineer is essential to design the structural elements of your extension and provide calculations for Building Control.

  •  Absolutely. Underfloor heating is a popular choice, offering efficient heating and freeing up wall space.

  •  While we don't offer in-house kitchen design, we collaborate closely with local kitchen designers to bring your vision to life.
