Flat conversions, HMOs and change of use in South London

Turning a large house into flats or a licensed HMO, or a shop or pub into homes — with planning, licensing and Building Regulations handled together.

Flat conversions & HMOs by Alozie Architects

Converting a house into flats needs planning permission almost everywhere in London, and the councils we work in have policies on minimum unit sizes, amenity space, cycle storage and — increasingly — restricting the loss of family homes. Knowing those policies before you buy is the difference between a good investment and a refusal.

HMOs are a special case: several South London boroughs, including Croydon, have removed permitted development rights for small HMOs, so a full application is required. We design layouts that meet the licensing standards on room sizes and shared facilities as well as the planning tests.

For commercial-to-residential — pubs, shops, offices — we assess whether the Class MA prior approval route applies or whether a full change-of-use application is needed.

How it works

Every conversions & hmos project follows the same five stages — feasibility, concept, planning, technical design and on site — on a clear fixed-fee agreement covering design, planning and building regulations. Read about how we work.

Flat conversions & HMOs: common questions

Do I need planning permission to convert a house into flats?
Yes, in almost every case. The council will assess unit sizes against the London Plan standards, outdoor space, parking and the effect on the street.
Do I need planning permission for an HMO?
For up to six occupants, only where the council has an Article 4 direction removing permitted development rights — which Croydon and several other boroughs have. Larger HMOs always need permission, plus a licence.
