Question 1

Do I need planning permission for internal renovation work in a Mayfair or Belgravia apartment?

Accepted Answer

Internal works within a listed Mayfair or Belgravia property — kitchen refits, bathroom refits, replastering — generally don't require planning permission but may require listed building consent where structural walls are involved or original features are affected. In unlisted apartments within conservation areas, internal changes are normally unrestricted. Westminster City Council's heritage team can advise on specific properties. TB&D checks the listed status of every Westminster address before quoting.

Question 2

Can you renovate a flat in a Marylebone or Paddington mansion block?

Accepted Answer

Yes — full flat renovations in the Howard de Walden estate (Marylebone) and the converted mansion blocks in Bayswater and Paddington are a core part of TB&D's work in W1 and W2. Most leasehold flats require a licence to alter from the freeholder before structural changes, layout reconfiguration or wet-room installation. TB&D advises on what your freeholder will need — typically structural drawings, materials specifications and contractor insurance certificates.

Question 3

What's the typical cost of a full flat renovation in Westminster?

Accepted Answer

Full flat renovations in SW1, W1 and W2 — new kitchen, new bathroom, flooring, replastering, joinery and decoration — typically run £80,000–£200,000 for a two- or three-bedroom flat, depending on flat size and specification. Premium finishes (natural stone, bespoke cabinetry, underfloor heating) push toward the upper end. TB&D provides fully itemised quotes within 48 hours of the site visit.

Question 4

What party-wall obligations arise when renovating Westminster mansion blocks in Marylebone and Bayswater (W1/W2)?

Accepted Answer

In the leasehold mansion blocks of W1 and W2 — including the Howard de Walden estate in Marylebone and the large stucco mansion conversions in Bayswater — the floors between flats and the dividing walls are party structures under the Act. Any structural penetration, wet-room installation on a shared floor, or wall removal near a dividing wall triggers both a Party Wall Act notice to the adjoining owner above, below or beside, and a licence to alter from the freeholder. TB&D Construction coordinates the notice and licence together so neither process delays the other.

Question 5

What renovation and project capabilities does TB&D Construction bring to the City of Westminster?

Accepted Answer

Westminster's residential stock spans Grade I and II listed Georgian townhouses in Belgravia (SW1) and Mayfair (W1), Edwardian and Victorian mansion blocks in Bayswater (W2) and Pimlico (SW1), and the converted historic buildings of Marylebone. TB&D Construction handles full flat renovations within freeholder licence constraints, kitchen and bathroom refits in listed buildings, structural alterations in unlisted mansion blocks, period restoration of original Georgian and Victorian joinery, and boiler replacements via our Gas Safe registered partner. TB&D carries £1m PL and £5m EL insurance and holds a 9.92/10 Checkatrade rating.
