Overview

Leconfield House is a proposed office building redevelopment on Curzon Street in Mayfair, London W1.

The new plans designed by EPR Architects see the reconfiguration and extension of Leconfield House.

The ground and first floors will be transformed to include restaurant space with a new stone facade on the ground floor.

The first basement level will house a health club and spa, while levels 2 and 3 will feature a health and diagnostic center with treatment, diagnostic, and doctor's rooms, as well as retail and food and beverage spaces.

Levels 4 and 5 will offer co-working spaces.

Levels 6 and 7 will be replaced with new rooftop levels featuring rooftop restaurants and terraces, and the rooftop will also host relocated plant equipment, screened from view from the street.

An additional basement level will be added for administration, staff areas, and mechanical plant spaces, including an improved sprinkler system.

Delivery arrangements will be enhanced by consolidating off-site deliveries to reduce the number of deliveries to the site.

History

The existing 7-storey building was the headquarters of MI5 following the Second World War from 1945 until the mid-1970s.

Leconfield House is situated on a site that was once part of Chesterfield House - a Palladian mansion built from 1746-1752 for Philip Stanhope, the 4th Earl of Chesterfield. The house was designed by Isaac Ware. The building sat on the corner of South Audley Street and Curzon Street, facing the park. Demolished in 1934 and replaced by Chesterfield House and Leconfield House.
