    Common Questions

    Yes. We're familiar with the Grosvenor Estate's specific approval processes, design guidelines, and contractor requirements for Mayfair properties.

    Absolutely. Mews conversions are one of our specialities — we maximise space in these compact footprints while respecting their unique character and Westminster planning requirements.

    We use unmarked vehicles, maintain clean and tidy sites, coordinate with porters and neighbours, and assign a dedicated site manager as a single point of contact.

    Most require Westminster planning consent due to conservation area status. Listed buildings need additional listed building consent. Grosvenor Estate properties also need estate approval. We manage all of this.

    6–14 months depending on scope, listed building requirements, and estate approvals. We provide a detailed programme with key milestones before work starts.
