Extend your home with a considered layout and a coordinated build. We cover rear, side and double storey extensions, from groundwork and structural work through to the interior finish.

What your project can include

  • Groundworks, foundations and drainage
  • Brickwork, blockwork and structural steel
  • Roof construction and weatherproofing
  • Plumbing, electrics and underfloor heating
  • Plastering, decorating and interior finishes

Planning the work

Your drawings, site access, existing structure and specification determine the scope. We discuss these with you and set out the agreed work in a written quotation.

Your project, explained.

01

Choose the right space

A rear extension can create a larger kitchen or living area. A side extension can improve circulation, storage or utility space. A double storey project can add rooms on both floors. The layout follows your drawings and the way you want to use the home.

02

Connect the new and existing rooms

We discuss structural openings, floor levels, rooflights, glazing and how the existing services connect to the new space. These decisions help establish a coordinated scope before the build.

03

Plan the finishing specification

Kitchen installation, bathrooms, underfloor heating, flooring and decorating can be included where agreed. Your quotation identifies the included work and any items you will supply.

Every property is different. Your written quotation confirms the included work and any client-supplied items.
