101 Park Street, Mayfair

In the heart of Mayfair, a private client wanted to transform a traditional London townhouse into a refined, modern residence.

We provided cost management and contract administration, working closely with the client’s representative to turn their ideas into a clear, detailed tender package. We then led a single-stage tender under a JCT Standard contract to appoint the contractor.

Precision costing, confident delivery

Lowering the lower-ground floor to create usable space was one of the most technical steps. This involved underpinning party walls and keeping open communication with neighbours. We also collaborated with a specialist interior designer to balance bold, contemporary finishes with the home’s Victorian character – all within planning requirements and Grosvenor Estates’ guidance.

Modern comfort behind historic facades

The refurbished townhouse now offers high-end living across every floor. Reconfigured layouts and improved ceiling heights make the most of the footprint. A new rooftop garden and terrace bring rare outdoor space to central Mayfair. Inside, a calm blend of contemporary style and period detail gives the home warmth and character in equal measure.

Adding value through thoughtful execution

Our cost control and contract administration delivered quality without compromising heritage or the client’s ambition. The result is a discreet, luxurious home that enhances both the property and the street.
