A substantial property refurbishment in one of London’s most desirable and prestigious addresses is now complete and offers mixed-use accommodation of private housing, retail units and commercial office space. Windows by Mumford & Wood, specialist manufacturer of period-style, high performance windows and doors, have been specified for this complex project.
In order to satisfy the strict design criteria set out by planners and architects, Mumford & Wood have addressed many issues in the design of both sash and casement windows and doorsets in order to match the original fenestration. The extensive structural refurbishment of the building involved the retention of the current facades although the property was underpinned and the existing basement slab removed, replaced and lowered. Mumford & Wood’s current window specification designs were adapted to meet, as closely as possible, the external detailing of the existing frame sections, and meeting rails on the replacement double glazed windows were required to stay in the same position in order to line up with stone features and brick work in the retained facades.
“This was not a one-size-fits-all project by any means,” states Paul Martin, Mumford & Wood. “Basically, our Conservation™ box frame sliding sashes, casements, fanlights and doorsets all had to be recreated to faithfully replicate the original frames which involved a great deal of intricate design input from us and adaptation of our standard product. But this is our manufacturing strength; this is what we do best.” Ground floor box frame windows required special, large meeting rails with a detailed mould fitted to the face; casements had special external feature moulding to the frame and casement fanlights had a special bar pattern – all of which were in keeping with the original windows.
“The large stair frame, over 7 metres high, was designed with a contemporary feel. The architects were very stringent on the detail of this window and we worked closely with them to achieve their vision. All drawings had to be approved prior to manufacture.” In this project the windows and fanlights were fitted internally in a check reveal showing only the exact frame proportions which matched the original windows.
