Over £5m

Project Description

The Quadrant was developed by Manor & Castle Development Trust Ltd, a social enterprise which uses profits from the centre to boost its regeneration work in south Sheffield.

The £12m state of the art development provides high standard office space for a variety of size of businesses within the South Sheffield area, from starter companies to larger scale firms requiring HQ accommodation.

The scheme was won through a competition for a design and incorporates two buildings based around streets running from the main entrance/exhibition and conference areas, set in a high quality landscaped area with surface car parking.

The client was looking for an innovative design for the buildings which could be split down into varying size units for different tenant requirements. The street acts as a focal point for access, meeting and social areas as well as providing natural daylight and ventilation.

By using low and renewable energy and environmentally friendly features, the Quadrant’s design makes the most of natural light, and requires minimum energy greedy heating and cooling systems. The roof includes photovoltaic tiles that convert sunlight into energy powering the building.

Terracotta tile hanging façade to all elevations
