Morgan Sindall Construction has officially started work on Mill Yard, a £180 million mixed-use development by Railpen and its development partner Socius.

The project aims to transform a central Cambridge site into a sustainable, vibrant neighbourhood.

Formerly known as Devonshire Gardens, the site was rebranded as Mill Yard in 2024, reflecting its prime location on Mill Road near the city centre. The development includes 110,000 square feet of office space, 70 build-to-rent apartments, refurbished railway cottages, a 2,100-square-foot crèche, a community events pavilion, and retail units set around a 1.55-acre public park.

Mill Yard, situated near Cambridge train station, will feature extensive green spaces, including a central pavilion designed by George King Architects. The pavilion will anchor the public park, providing residents and visitors with accessible outdoor space. Additional amenities include a perimeter running track, a play street, and secure cycle parking with end-of-journey facilities, making it the only office development in Cambridge offering such features.


Sustainability is a cornerstone of the project. Morgan Sindall has employed its Intelligent Solutions model to minimise environmental impact, aiming to divert 99% of waste from landfill and save 5,013 tonnes of embodied carbon. The completed buildings will be fully electric, powered by renewable energy sources, including rooftop photovoltaic (PV) panels, and will use responsibly sourced materials.

Wildlife will also thrive in the regenerated area, with plans for a 280% biodiversity net gain. Enhancements include bat, bird, and bee boxes, green roofs, hedgehog habitats, and evergreen planters. The site will primarily be car-free, except for blue badge spaces and electric vehicle charging points.

Railpen and Socius, in partnership with Morgan Sindall, have committed to generating over £60 million in social value for Cambridge, a target verified by Social Value Portal. Initiatives include employing 12 local homeless individuals, creating apprenticeship and work experience opportunities, and donating 500 volunteer hours. More than £30 million will be spent in the local supply chain to bolster the local economy.
