Sunstone’s headquarters are located in Doncaster and the cutting-edge design of the space is very much on-brand for the property developer. The interior is defined by graceful curves, with bespoke joinery pieces and sophisticated finishes. Giving the impression of a luxury home rather than a commercial workspace, the design includes a generous conference room, gym, staff lounge and dining area complete with wine storage. The facilities span over two levels and are linked by a striking spiral staircase.
