Question 1

What does a full kitchen and bathroom renovation cost in an NW3 Swiss Cottage mansion flat?

Accepted Answer

Budget depends heavily on how much of the flat is in scope. For a 90 m² two-bedroom Edwardian flat in NW3 — a complete kitchen refit, one bathroom replaced, walls replastered and new flooring laid throughout — expect a range of roughly £60,000 to £95,000 at current London rates. A second bathroom, bespoke fitted joinery such as alcove shelving or full wardrobes, and structural openings between rooms each add a material amount. We price every trade as a separate line in the written quotation so you can adjust scope before anything is agreed.

Question 2

Do I need freeholder approval before carrying out structural changes in my Swiss Cottage leasehold flat?

Accepted Answer

Yes, for almost anything beyond decorating. Removing a wall, altering drainage, opening up a chimney breast or modifying the flat's layout requires written consent from the freeholder or management company, usually in the form of a licence to alter with supporting drawings. Parts of NW3 also carry Camden conservation area designation, which brings additional controls over external changes. We identify exactly what consents apply to your specific block during the site visit — before we price the job — so there are no unexpected hold-ups once work is underway.

Question 3

How are the working weeks structured on a full NW3 mansion-flat renovation?

Accepted Answer

A complete renovation of a Swiss Cottage mansion flat — kitchen, bathrooms, replastering, flooring and decoration throughout — typically runs 10 to 16 weeks on site. Larger flats or those with extensive bespoke joinery or structural alterations sit at the upper end; a focused refit of two rooms can finish in five to seven weeks. Virtually every NW3 block imposes weekday working hours and restricts noisy phases to certain windows. We factor all those constraints into the programme, and start and completion dates are confirmed in the written quote before a single tool arrives.
