More than 100 timber windows are being installed at Sotheby’s in central London.

The windows, supplied by Bradford Joinery Manufacturing, were ordered by main contractor Techno Construction Ltd of Leeds for Sotheby’s administration building in Maddox Street. Westminster Council approved the job, which has a contract value of about £90,000.

  It involves 100 fully-finished and glazed sliding sash windows and a further 20 Heritage style units for the building’s front elevation.
