HMO conversions in London

Planning strategy, fire safety, licensing coordination and layout for houses in multiple occupation, for landlords and investors.

Well-designed shared kitchen in a modern HMO
The brief

The studio prepares planning strategies, layouts and technical designs for houses in multiple occupation, for landlords and investors.

Approach

Layouts are designed to exceed minimum standards for room size, daylight and shared space, because well-proportioned accommodation is more likely to be approved, licensed and occupied. Fire safety is integral to the plan rather than added to it.

Planning and regulation

Small HMOs may fall within permitted development unless an Article 4 direction applies; large HMOs require planning permission. Licensing, fire safety and Building Regulations are coordinated alongside planning.

Delivery

The studio manages the planning application, technical design and coordination with licensing 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 for an HMO conversion? +
Almost always in London, yes. Most boroughs have Article 4 directions requiring planning permission for C3 to C4 conversion (3-6 occupants). Large HMOs (7+ occupants) always need permission. We handle the 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.
What is the difference between a small HMO and a large HMO? +
A small HMO has 3-6 occupants forming 2+ households (Use Class C4). A large HMO has 7+ occupants (Sui Generis — requires full planning permission, additional licensing, and more stringent fire safety). Do not creep across the 7-person line without full permissions.
What yield can an HMO be expected to produce? +
A well-designed London HMO with high en-suite ratios typically generates 8-12% gross yield — significantly higher than a single let (3-5%). The difference between average and top-of-market yields is usually the layout design, not the location or the finishes.
