Reviewed by Joe Ashwell
First reported on The Construction Index
30 Second Briefing
Topping out of the five-storey MY Central office block marks a key milestone in Railpen and Socius’s £180m Mill Yard mixed-use campus on Devonshire Road, Cambridge, which will deliver 110,000 sq ft of flexible workspace, 70 build-to-rent apartments and a 2,100 sq ft nursery by 2027. Morgan Sindall Construction is targeting NABERS Design for Performance 5-star and BREEAM Outstanding ratings for the all-electric buildings, using its CarboniCa tool to pursue an embodied carbon saving of 5,013 tonnes and diverting 99% of waste from landfill. The scheme includes 1.55 acres of public green space with over 120 trees, green roofs, bat/bird/bee boxes, hedgehog habitats and a 280% biodiversity net gain target, plus a community pavilion by George King Architects, perimeter running track and secure cycle facilities.
Technical Brief
- Five-storey MY Central office block has structurally topped out, roof construction completed and accessible.
- Campus layout comprises three office buildings (MY North, South, Central), two residential blocks and a nursery.
- Mill Yard sits off Devonshire Road in central Cambridge, forming part of Railpen’s innovation cluster.
- Topping-out ceremony occurred Tuesday 10 March, with stakeholders touring the completed roof level.
- Workplaces are planned to overlook landscaped gardens, with internal layouts configured for collaboration-focused fit-outs.
- Public realm includes a restaurant, café/bakery and an outdoor pavilion by George King Architects.
- For mixed-use urban regeneration schemes, Mill Yard offers a reference for integrating commercial, residential and community functions around a central park.
Our Take
Within our 786 Infrastructure stories, very few UK schemes target biodiversity net gains above 200%, so Mill Yard’s 280% ambition in central Cambridge positions Railpen and Socius at the aggressive end of local planning and ESG expectations.
The 99% construction waste diversion rate at Mill Yard suggests Morgan Sindall Construction is aligning site practices with the more demanding NABERS- and BREEAM-led office projects in our database, which can give them an edge in future city-centre tenders with strict circular-economy criteria.
