What's included

Every extension is different, but most of ours include the following as standard.

Structural work

Foundations, steelwork, knock-throughs and structural openings, all signed off by building control.

Roofing & glazing

Flat, pitched and vaulted roofs, roof lights, and bi-fold or sliding doors onto the garden.

Kitchens & utility

Kitchen installation, plumbing, electrics and underfloor heating for the new space.

Finishes

Plastering, flooring, decorating and joinery so the new space feels part of the original house.

Party wall & planning

Help with permitted development, planning applications and party wall agreements.

Garden & drainage

Drainage, patios and landscaping to tie the extension into the outside space.

How we work

Building work is disruptive, so we keep the process simple and predictable.

01. Site visit

Ardian visits, listens to what you want and looks at what the building will allow.

02. Written quote

A clear, itemised proposal with a realistic programme. No vague allowances.

03. Planning & prep

We coordinate drawings, structural calculations, party wall matters and building control.

04. Build & handover

One team from strip-out to snagging, with a tidy site and a clean handover.
