What we can deliver
We agree the construction scope around the intended use of your premises. Office projects may include quiet meeting spaces and shared kitchens; gyms and studios need layouts that accommodate equipment and classes; shops need practical display, counter and customer areas.
Specialist requirements such as heating, ventilation, acoustics, electrical capacity and any approvals should be identified early so they can be allowed for in the quotation and programme. Read more about our Pilates studio fit outs and gym and fitness interiors.
