Fitzrovia Renovations & Design-Build — W1T

Yes. We take on a single shower room, en-suite or bathroom in a Fitzrovia flat or townhouse as a job in itself, without a wider refurbishment around it. Send the room size, photographs and the floor it is on, say where the shared stack runs if you know, and tell us whether another bathroom will stay usable during the work.

Check the full address. Westminster’s side includes the Charlotte Street West, Cleveland Street, East Marylebone, Hanway Street and Harley Street conservation areas, and Camden’s takes in all or part of the Bloomsbury, Charlotte Street, Fitzroy Square and Hanway Street areas. The council boundary runs down Cleveland Street and through Charlotte Place to Rathbone Place and Hanway Place, and part of Fitzrovia near Oxford Street now has the Oxford Street Development Corporation as planning authority.

Check the address. None of the minor-alteration directions on Westminster’s list falls in Fitzrovia, and Camden’s heritage index lists no direction for its Fitzrovia conservation areas, but each council has a basement direction covering its whole area. Listing applies building by building: 1, 1A and 2–8 and 33–40 Fitzroy Square are Grade I, and 143–149 Cleveland Street is Grade II. Inside a listed building, consent can be needed for work that touches its special interest.

Check before ordering. A flat has no householder permitted development rights, so any external change needs its own planning check, and in a listed building listed building consent can apply. The Fitzroy Square appraisal counts inappropriately detailed or proportioned replacement windows among the changes that have harmed the area. Compare repair, draught-proofing and secondary glazing first, and read the lease for any clauses on windows.

Ordinary internal works are generally not development, so they do not usually need planning permission, though merging two flats into one home in Westminster is assessed under City Plan Policy 12. The lease decides whether written landlord consent is needed and on what conditions. In a listed building, internal changes affecting special interest can need listed building consent, and the Building Regulations apply either way.

An engineer should confirm what the wall supports and how the floor runs, and the new bathroom position needs a workable fall to the shared stack as well as water and extract routes. In a listed building, Westminster’s City Plan treats plan form and room hierarchy as elements to protect. In a flat, check the lease, the sound requirements and whether the Party Wall Act applies.

Treat it as a separate project from refitting an existing lower ground floor. Both councils have removed householder rights for basement development through Article 4 directions. Westminster’s Policy 50 limits depth and garden coverage, and a new basement there is a Level 3 project needing a Construction Management Plan; in Camden, any basement excavation needs planning permission and new or enlarged basements need a site-specific Basement Impact Assessment.

On either side of the boundary, noisy work may run from 8am to 6pm on weekdays and 8am to 1pm on Saturdays, with none on Sundays or bank holidays. In Westminster, piling, excavation and demolition stay on weekdays, and out-of-hours work needs section 61 consent, given only exceptionally; in Camden, seek it at least 28 days ahead. Leases sometimes set tighter hours, so check yours.

Line them up item by item: the same rooms, quantities, repairs and finishes, and the same written provisional sums, exclusions and VAT position. Ask how listed fabric, protection of shared stairs, street licences and landlord requirements are handled, and which authority’s consents each one assumes. The address does not justify a set uplift or completion date, so agree the sequence once the main unknowns have been investigated.
