VELUX® GBI Head Office

Project description

Creating the perfect office environment

In a two-storey extension with large, horizontal and vertical spaces, optimised acoustic performance was crucial to ensuring comfort and optimal working conditions for the 160 staff.

Developing a two-storey, 37,673ft2 extension for 160 people presented a range of challenges in itself, but incorporating a curved ceiling into the design added an entirely different set of obstacles. Our expertise was required to develop a solution that would improve the acoustic performance of the VELUX® headquarters and facilitate the ideal office environment.

Working with Sinclair Watt Architects, ISG plc and PFP Ltd, we were able to deliver a solution that provides optimal acoustic performance, meaning 160 VELUX® employees can enjoy the ideal working atmosphere.
