House-to-flats conversions

The conversion of houses into self-contained flats, with planning strategy, layout and structural coordination resolved together.

Self-contained apartment interior with open-plan living and kitchen
The brief

The conversion of a house into self-contained flats requires planning, layout and construction to be resolved together.

Approach

Layouts are designed to exceed the Nationally Described Space Standard, with attention to daylight, acoustic separation, fire safety and refuse and cycle storage. Units that only meet the minimum are frequently refused.

Planning and regulation

Conversion to flats requires planning permission, and many London boroughs protect family housing through specific policies. Building Regulations apply to separation, fire safety and services.

Delivery

The studio prepares the planning case, the technical design and the coordination with structural and building control requirements through to completion.

Fees

Fees are fixed for each stage and confirmed in writing once the scope is agreed. Construction cost depends on the site, the specification and the procurement route, and is established through an indicative cost plan at feasibility stage.

Frequently asked questions

Is planning permission required to convert a house to flats? +
Yes — full planning permission is required. The council assesses unit sizes, natural light, parking, refuse, and neighbourhood impact. We handle the full application.
How are fees and construction costs established? +
Fees are fixed for each stage and confirmed in writing once the scope is agreed. Construction cost depends on the site, the specification and the procurement route, and is established through an indicative cost plan at feasibility stage.
Does a flat conversion increase property value? +
Typically yes. The uplift depends on location, unit quality, and local demand. We can estimate the uplift during feasibility.
