Maison Estelle

THE LINE UP

Developer: Ennismore
Architects: Blair Associates
Interiors: Roman and Williams
Quantity Surveyor: Greenway Associates
Structural Engineers: Design ID
MEP Engineer: Hoare Lea

Greenway Associates originally commenced work on this project in 2017, when Ennismore aimed to redevelop the Grade-1 listed building at 6 Grafton Street, Mayfair, into a private members club.

OUR ROLE

Greenway Associates are proud to have been involved as the Quantity Surveyor for the initial feasibility studies, cost planning throughout all stages (including interiors), as well as post contract, (excluding final interior finishes).

ORIGINAL SITE

The beautifully preserved building, designed by Sir Robert Taylor in 1772, provided a beautiful canvas for designers to shape, with high ceilings and plenty of original features. However, this was not without its challenges, with serious repairs required throughout the building, and a logistically tight corner site.

Significant repairs were required to the cantilevered stone staircase. Strengthening works were required to all the 18th Century old beams within the timber floors and many of the original roof trusses were strengthened, repaired or replaced.

PROJECT CHALLENGES

Additionally, the site is directly located above where the ancient river Tyburn continues to run today. The map below shows where the River Tyburn flows underneath the city streets. The blue line marks the flow of the river and the Grafton St project is indicated by the red star. In contrast to the surrounding grid system, these curved streets were built to follow the river’s path towards the Thames.

Significant alterations were required to the project basement in order to accommodate a subterranean bar and food preparation facilities. Undertaking these alterations over the Tyburn Culvert (as pictured below) caused the Structural Engineers some interesting challenges!

COMPLETED FEB 2022

Ennismore developed this project into the extremely private “Maison Estelle” members club which offers multiple restaurant, bar, lounge, retail and nightclub spaces, with a curated programme of events. Maison Estelle has quickly gained cult status, with a long list of celebrity guests.
