House Extensions & Loft Conversions

Extensions and loft conversions, designed and approved

We design rear, side return, wraparound and two-storey extensions, and loft conversions, for London homes. We take you from the first visit to approved drawings, with fixed fees for each stage.

How it works

  1. Visit and survey

    We meet you at home, talk through your ideas and measure the property.

  2. Design options

    We prepare two or three layout options with 3D views so you can see the space.

  3. Planning or permitted development

    We check what your project needs and prepare the drawings.

  4. Building Regulations

    We produce the technical drawings your builder and building control need.

Price
Design and planning drawings from £1,500, plus the council’s application fee.
