Client: Trinity College, Cambridge

Services: Buildings, Infrastructure, Advisory & Planning, Building Standards

Architect: Scott Brownrigg

Value: £19.5m


Unit 26 - 27 is an office development on the site of two previous buildings, which were demolished to make way for the development. The project was developed to CAT A standard and is occupied by science-led tenants that meet the Science Park’s occupation criteria.


At circa 70,000 sqft and at three storeys high, the building sits on a landscaped podium over undercroft parking. The building is a 9m x 7.5m structural grid, and in order to meet the architectural brief for a distinct jagged form with significant cantilever floor plate, it uses a post-tensioned concrete slab construction, whilst simultaneously delivering commercial value to the landlord by using stepped blade columns in the facades to maximise the net internal floor area.

The four-storey internal atrium, from undercroft car park to roof, is dominated by a cantilever steel staircase which floats over the large reception area providing access to all levels.

Externally, the landscaped podium at first floor contains permeable paving and SuDS systems, minimising the buried attenuation required.
