Historic Building Repair and Maintenance
‘Section 20’ Major works / Contract Administration


EKA was instructed to carry out a window feasibility report ahead of an intended window replacement project and full external redecorations to this rather unique Grade II* listed building in the Queensgate Conservation Area of London. This included planning and listed building consent applications to replace all original metal casement windows with new doubled glazed replicas. The project has been tendered and works start in 2019 for the window replacement and full external redecorations.

This building on Palace Gate is of enormous historic significance. It was completed in 1939 by the famous architect Wells Coates and it belongs stylistically to interwar period modernism which makes its statutory listing of Grade II* very rare since only 5.5% of all listed buildings have a statutory listing of Grade II* –  and only 3% of those were constructed between 1900-1944. It is characterised as one of the most innovative blocks of flats built in Britain in the 1930s, designed by one of the leading modern architects of the time.

After consultation with Historic England and RBKC, EKA conducted a joint survey with the window historian Charles Brooking to all the windows, in order to identify the original window section and details, the number of the historic windows surviving, but also in order to receive specialist advice for our proposals. It has been identified that 70% of the original windows have been either replaced or altered over the years with several different units/ styles.

Following the advice given by Historic England and the RBKC, the Historic Paint Consultant Patrick Baty was appointed to analyse the paint of the external surfaces. Through this we identified the original colour and all the different colour schemes used up to the present day, and we were able to date most of them – such as the colour scheme during the war.

We will update this case study once this unique project has been completed.
