The Building - A Rich History

This magnificent Grade 2 listed building was originally designed by Edward Mountford, architect of the Old Bailey, and was built in two phases in 1893 and 1896. It originally housed St Olave’s Grammar School and, more recently, Lambeth College.

 Purchased in recent years by theLalit Suri Hospitality Group for redeveloping into an Opulent Boutique Hotel.

 The Requirement 

Our Client required New Windows for this redevelopment , to improve the thermal efficiency (U - Value), in order to be more compliant with modern environmental credentials. 

As the building is listed, Sash were required to produce models and full sized samples to gain approval from the planning department. This was to demonstrate that the profiles of the new windows matched the original ones, in order that the facade maintained the historic integrity. 

The Challenge

The challenge was to design unique solutions to facilitate AOV smoke windows in the Great Hall, these windows were large in scale, they had to fulfil their functionality and yet retain the original historic facade and grandeur.
