Your Mayfair builder.
Architect-led. Fixed price.
Mayfair — W1 — the Georgian and early Victorian estate district between Hyde Park and Regent Street. Most single-family homes are Grade II or II* listed; the mews behind the main streets offer a different scale of work. Nicholas Elias RIBA leads all Mayfair submissions.
Four services. One team. One number.
Mayfair projects: mansards on Georgian terraces under listed-building consent, mews refurbishments and rear-roof additions, full interior conversions, and bespoke joinery at the highest specification.

Georgian W1 — listed mansards and mews conversions at the highest specification.
Westminster's Mayfair submissions require listed-building consent alongside planning, and the design phase typically runs 6–9 months. Our Chelsea and Belgravia track record covers this standard.

What homeowners ask before booking a Mayfair builder.
What scale of loft project is typical in Mayfair?
Mansards on Georgian terraces are the norm, with budgets typically £250k–£500k all-in. Listed-building consent is required on most properties, and the design phase often runs 6–9 months. Mews properties are simpler — single-storey rear-roof additions with rooflights, typically £80–£140k.
