Avenfield House
Two Duplex Penthouses
 
Client:
Charles Street Estates Ltd.

Location:
Park Lane, London W1

Summary of Project:

The conversion of three existing apartments into two high specification duplex penthouses.

The project is located in the Mayfair Conservation Area within the City of Westminster, and as well as the necessary Council approvals also required negotiated permissions from estate freeholders and building owners.

Avenfield House is an existing eight storey building with residential uses on  the upper floors and mixed commercial uses on the ground and first floors, the building remained occupied throughout the duration of the refurbishment contract.

The architecture and space planning responds to the location by taking full advantage of panoramic views of the London skyline to the east and Hyde Park to the West. Living spaces are located at the highest floor level with large sliding doors opening onto west facing balconies, double height windows on the eastern elevation provide views of London’s principal landmarks.

Each penthouse has a master bedroom suite and three other bedrooms, all have individually designed bathrooms and interiors. 

The work involved:

  • Co-ordination of a full consultant team 
  • Extension of the building at roof level
  • Strip-out of existing walls, interiors and services allowing for completely new space planning and interior design. 
  • Installation of new heating, cooling and hot and cold water services, new electrical infrastructure and integrated intelligent building management and audio visual system with remote and local connectivity.
  • Refurbishment of common parts including boundary treatment, forecourt, entrance lobbies, passenger lifts, electrical sub station, and building services.

The ground floor entrance lobby and forecourt were remodelled and two new pasenger lifts were installed within the core of the building.
