Question 1

How much does it cost to renovate a mansion-flat apartment in South Kensington, SW7?

Accepted Answer

Budget between £75,000 and £145,000 for a two- to three-bedroom apartment in SW7 where the scope runs to a full strip-out, replastering, a new kitchen and bathroom, hard flooring throughout and redecoration. Lateral flats — those formed by merging two original Victorian units — sit toward the upper end because the structural alterations and increased floor area push up materials and programme. Specialist lime repair of original cornicing and ceiling roses adds further cost but protects the character of the flat. All of those elements arrive as individual lines on the quote so you can weigh each one.

Question 2

Can original Victorian plasterwork in a SW7 flat be saved, or does it need replacing?

Accepted Answer

Most original cornices, panel mouldings and ceiling roses in South Kensington mansion blocks can be retained and repaired rather than stripped. The deciding factor is the condition of the lime substrate beneath; our plasterer assesses it during the survey visit and confirms what can be stabilised or infilled to profile, and what has to be recast in matching lime. Sections with failed keys are reattached where the backing is sound and replicated in profile where it is not. We cost restoration separately from the main plastering so you can see exactly what keeping the original fabric adds to the budget.

Question 3

Do leasehold flats in South Kensington require freeholder approval before building work starts?

Accepted Answer

Yes — virtually every leasehold flat in an SW7 mansion block requires the freeholder or managing agent to approve works beyond basic redecoration, and many require a formal licence to alter alongside a schedule of works before wet trades or structural changes begin. RBKC may also require Building Regulations approval for drainage, electrical and structural elements even within the existing flat envelope. We identify the consents needed at the survey, prepare the schedule of works and technical drawings your managing agent will ask for, and coordinate sign-off before any trades go in.
