Why a local Mayfair builder

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.

Mayfair builder FAQ

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.
