Earl’s Court is tall stucco terraces and red brick mansion blocks. Most were divided into flats.

A mansion block roof belongs to the building, not the top flat. Its freeholder decides first.

Philbeach and Earl’s Court Village are conservation areas. In Philbeach, even repainting a front needs planning.

Policy CD12 resists added storeys on intact terraces. Rows already broken can allow infill.

Our closest built work is a Chelsea terrace, up to its roof terrace.

Infill

Can the top flat in an Earl’s Court mansion block build upwards?

Only with the freeholder’s agreement and planning permission.

Mansion flats carry no permitted development rights.

Other leaseholders may have a say under their leases.

Does the Philbeach Article 4 affect roof work in Earl’s Court?

It shows how closely fronts are controlled there.

Even painting a house front needs planning in Philbeach.

A roof change will be judged at least as tightly.

Can an Earl’s Court terrace with several mansards take another?

Possibly. Infill can be permitted where the roofline is already broken.

We map every roof in the row first.

Will joining Earl’s Court flats give me the loft too?

Merging separate homes meets Policy HO1, which resists it.

A loft is a separate question for the freeholder and the council.
