Extensions & Loft Conversions in London

Explore the potential for more living space, from a garden-facing extension to a room in the roof.

Explore additional living space in your London home

An extension or loft conversion can be considered when the existing layout no longer suits your needs. Begin with the purpose of the space: a larger kitchen, an additional room or a better connection to the garden. The possibilities depend on the property, its structure and the assessments needed for a specific proposal.

Consider how an extension connects to your home

Rear and side extension ideas

Describe the space you hope to add and how it would connect to existing rooms. Photographs of the rear or side of the property, together with available drawings, help explain access, boundaries and the relationship to outdoor space.

Daylight, circulation and garden access

More floor area is only one part of an extension brief. Think about the route through the house, where furniture will sit and how doors or glazing might affect daylight and privacy. These are design questions to explore before selecting finishes.

Understand the starting points for a loft conversion

Roof space and staircase position

An initial loft brief should describe the existing roof space and possible staircase location. Usable space, access and the relationship to the floor below require assessment; photographs cannot confirm that a particular layout is achievable.

Services and the intended room use

A bedroom, workspace and bathroom each introduce different requirements. Identify the intended use early so heating, lighting, ventilation and any plumbing can be considered alongside the overall design.

Outline your extension or loft-conversion requirements

  • Rear and side extension enquiries
  • Loft conversion and roof-space enquiries
  • Connections between new and existing living areas

Feasibility, design and approvals

Feasibility, planning requirements, structural design and building regulations need project-specific assessment. No approval or additional floor area is assumed.

Questions about extensions and loft conversions

Should I send drawings with my extension enquiry?

Send any existing or proposed drawings you already have, along with photographs and a short brief. If you do not have drawings, explain the change you are considering so the next assessment or design step can be discussed.

Does an extension or loft conversion always need the same approvals?

No single approval route should be assumed for every property. The proposal, location and building circumstances need to be reviewed by the appropriate professionals before work or permissions are confirmed.
