1 Grosvenor Square – Windows Fit for a President

Grosvenor Square, London View project details

Project Description

Following the completion of Twenty Grosvenor Square, George Barnsdale was selected to design, manufacture and install timber windows into a new development at No 1 Grosvenor Square, which promises to be one of the most revered addresses in the UK. Formerly the home of the US Embassy and more recently the Canadian High Commission, this stunning new residential project is being developed by contractors Mace Group on behalf of  Lodha UK . 

250 timber windows and doorsets are being manufactured in the Lincolnshire factory and installed by George Barnsdale’s dedicated onsite installation team according to the plan of works. As part of the listed building consent, the original neo Georgian facade has been retained by removing the stones one by one, labelling them and storing them offsite prior to being reinstated to their former glory. George Barnsdale has decades of experience in designing and installing windows for retained facades and has an extensive bank of interface designs to meet the unique requirements of each project.

A combination of  Box sliding sash windowsflush casement and tilt and turn opening in windows  make up the project incorporating acoustic glass to deliver the soundproofing requirements specified by the architects. Working with acoustic engineers and the wider team, the optimum solution was developed using our extensive library of acoustic data.
