Co-Living & Large HMO

Co-Living & Large HMO Architects

Beyond the standard HMO. Feasibility for co-living and large shared-living schemes, where amenity, management and fire strategy carry as much weight as the room count.

How it works →

The Opportunity

Co-living and large HMOs work on a different model to a five- or six-bed conversion: more generous shared amenity, on-site management, and a building designed around communal living rather than a house with extra locks on the doors. Done well, the yield and the planning case are both stronger for it.

What Is Hard

The Risks Unique To
Co-Living & Large HMO.

  • Sui Generis, not Class C4

    Once a scheme moves beyond the small-HMO thresholds, it falls outside Class C4 and needs its own planning permission, judged on its own merits rather than against a permitted-development fallback.

  • Shared amenity that actually works

    Communal kitchens, lounges and laundry have to be sized and located for the number of residents actually using them, not a token room ticked off a policy checklist.

  • Fire strategy and acoustics at scale

    More occupants and more shared circulation raise the fire engineering and acoustic separation bar well above a standard house conversion, and getting it wrong is expensive to fix after the event.

  • Management and licensing

    Larger schemes usually need a formal management plan and sit across more than one licensing regime at once, which has to be designed for, not bolted on afterwards.

How We Solve It

Built For
Co-Living & Large HMO.

Sketch Schemes

One to two layout options, drawn over your estate agent or measured plans.

Circulation and layout tested for a larger building, including how residents actually move through shared spaces.

Planning Policy Analysis

Planning policy, flood risk, Article 4, conservation, and heritage assessment.

Sui Generis precedent, licensing regimes and amenity policy read together, not treated as a bigger version of a small-HMO check.

Risk Register

Structural, environmental, and commercial risks, quantified with cost implications.

Fire strategy, acoustic separation and management-plan risk named and costed at feasibility stage.

I decided to work with Ed and the team due to their experience in HMO conversions. I was purchasing my first building to convert and needed expert guidance. The whole process was so enjoyable and the results were fantastic!

There's overlap, but co-living usually implies more generous, better-designed shared amenity and often on-site management, marketed as a lifestyle rather than simply a shared house. Planning officers increasingly expect that distinction to be visible in the design, not just the marketing.
