Flat Conversions in Croydon: what actually decides it

Croydon has a large stock of generously sized Victorian and Edwardian houses, which makes conversion attractive — and means the council sees a great many applications. Refusals cluster around a predictable set of issues: undersized units, poor natural light to habitable rooms, inadequate refuse and cycle storage, no private amenity space, and parking pressure on already saturated streets.

The national space standards are the baseline, not the target. A one-bedroom, one-person flat has a minimum gross internal area, and a scheme that only just clears it while offering a poor internal layout is far more likely to attract an objection than one designed properly from the outset.

Change of use also carries a separate question from the physical works. Whether you need full planning permission, prior approval, or both depends on the existing lawful use and what you are proposing. We establish that at the outset rather than discovering it after drawings are paid for.

How we work

Fixed fee, agreed in writing before any work starts — quoted after your free consultation, so it reflects your actual property rather than an average. A householder application to Croydon Council carries a statutory eight-week determination period.

Step 1

Free consultation

We talk through what you want to achieve, look at the property and tell you honestly whether it is likely to get consent.

Step 2

Survey & feasibility

A measured survey plus a check of planning history, constraints and permitted development rights for your specific address.

Step 3

Design & drawings

We develop the scheme with you and produce the drawings the council needs, revising until you are happy.

Step 4

Application & decision

We submit, handle the case officer’s questions and negotiate amendments rather than accepting a refusal.

Flat Conversions in Croydon: common questions

Do I need planning permission to convert a house into flats in Croydon?

Yes. Converting a single dwelling into two or more self-contained flats is a material change of use and always requires planning permission, regardless of whether external works are involved. Additional consents may also apply, including building regulations approval and, for larger HMOs, licensing.

What are the minimum room sizes for a flat conversion?

The nationally described space standards set minimum gross internal areas by number of bedrooms and occupants, along with minimum bedroom sizes and floor-to-ceiling heights. Meeting them is necessary but not sufficient — light, outlook, storage and amenity space all get assessed too.

Can you handle the whole process, not just the drawings?

Yes. We survey, design, prepare and submit the application, respond to the case officer, and produce the technical drawings for construction. For conversions we would usually recommend that route, because these applications very often need negotiation rather than a single submission.
