Physical performance for the replacement fenestration was put on a par with sympathetic styling by the project team responsible for the conversion of a former Royal Mail building in the heart of London; seeking to create residential accommodation as well as a contemporary design studio with a light and comfortable working environment.
Howick Place in Westminster dates from 1894 and had served as a sorting office until developer, Fabbriche & Ceramiche, purchased the property. The painstaking refurbishment of the premises, led by Squire and Partners, involved Crittall Ltd in supplying some 200 of its Corporate 2000 windows under a sub-contract package for ISG Interior & Exterior Plc.
Crittall worked in close cooperation with both the main contractor and the architectural consultants to ensure its high performance steel framed units met the project’s wide ranging requirements; including planning conditions, thermal performance and physical security.
The project architect at Squire and Partners commented: “I have used Crittall on other contracts in the past and knew they would be one of the few companies able to supply the profile required to match the original fenestration in this building. We also required a high specification in terms of thermal performance and Crittall therefore supplied argon filled 28 mm units to match the requirements of the Building Regulations.
“In terms of the design support the manufacturer’s technical representatives responded well when coming back to us with information and possible solutions. This was a major project and the spaces created are very bright and attractive, with the slim window profile offering the maximum transmission.”
The majority of the windows supplied for Howick Place are of the side-hung, open in configuration and were finished in anthracite grey polyester powder coat paint over the galvanised corrosion protection. The sealed units feature a 6.4 mm thick clear laminated inner pane with low-E coating, separated from a 6 mm clear toughened outer pane by the 16 mm gas filled cavity
