Architecture for London homes

Every project starts with a close look at the house you already have.

All services
  1. House extensions Rear, side and wraparound extensions that fix how the whole house works, not just add floor area. Timber-framed kitchen extension with diagonal struts and roof lights at Albion Drive, Hackney
  2. Roof terraces & lofts Outdoor space and extra rooms where there seemed to be none: on flat roofs, in tall rooms and in the roof. Completed roof terrace at dusk on Godfrey Street, Chelsea
  3. Back-to-brick refurbishment When a house needs everything, we strip it back to the structure and replan it to work hard for every square metre. Refurbished penthouse living room under a pitched roof with roof lights at Shelton Street, Covent Garden
  4. Garden studios A workspace, studio or den at the end of the garden, designed with the same care as the house. Timber-clad garden studio with steel-framed glazing in a Hackney garden

Conservation areas and listed homes. Planning approvals in Chelsea, Covent Garden and Hackney, including a roof terrace won at appeal.

Precision design

Every part of the building, from the square centimetre to the square metre, is made to work hard.

About Theme2

  1. Find the hidden space

    We study the existing house closely and find room, space and storage that aren’t obvious at first.

  2. Spend to gain

    Everything new has to add something. Replacing like for like is spending money to stand still.

  3. Bring light deep inside

    Double-height spaces, roof lights and clerestory glazing, so no room is left dark behind an extension.

From first call to finished house

How we work
  1. 01

    Feasibility call

    Free, 30 minutes. Tell us about the house and what you want from it. We’ll talk through what’s likely to be possible, the planning route and the next steps.

  2. 02

    Survey and options

    We measure the house and look for the potential it already has, then show you options: what’s necessary, what’s desirable and what’s possible.

  3. 03

    Planning

    Drawings, a design and access statement, and talks with planning and conservation officers where they help. Permitted development, full planning and appeals.

  4. 04

    Technical design

    Detailed drawings for building regulations, structure and construction, down to stairs, joinery and bathrooms.

  5. 05

    Construction

    We stay involved on site, so what gets built is what was designed.
