Green Street Duplex Penthouse, Mayfair

Base Interior

Green Street Duplex Penthouse, Mayfair




Mayfair, London W1



This interior was created and project coordinated for a private developer that we have worked with many times over the past 8 years.

This was one of the most complex architectural projects that we have undertaken in-house, which saw the staircase relocated leading to interior space gains as well as formation of a larger exterior roof terrace.

Inspired by the period architecture of the building and driven by our Client’s desire for luxury and timeless sophistication, we introduced textured polished plaster, tailored upholstery and a divinely sculptural staircase and balustrade all flooded with light from our bespoke skylight and door.

As part of the brief, the Client required air conditioning, a high specification Modulnova kitchen featuring top of the range Miele appliances, a Lutron system to control the lighting, Lutron curtains and blinds and bespoke joinery throughout.

Base Interior designed and coordinated all aspects of the refurbishment, including all permissions, tendering, procurement and Client and Contractor liaison.
