A decade in the making: Stag Brewery redevelopment secures final approval

Following a decade of negotiation and a series of planning submissions, approval has now been secured from the Planning Inspectorate for the comprehensive residential-led redevelopment of the former Stag Brewery site.

Set on the banks of the River Thames in Mortlake close to the finish line of the world-famous Oxford vs Cambridge Boat Race, this historic site has lain vacant since completing its last brew in 2015. Spread across 22 acres, this Squire & Partners-designed mixed-use scheme will add 1,075 homes, a new 1,200-pupil secondary school, offices, a hotel and a full-sized community football pitch, whilst a range of retail units, a cinema, bars and restaurants will help create a thriving new high street. Nine acres of green and open spaces will punctuate the site, with new pedestrian and cyclist access routes enabling access to the river.

Development manager, Dartmouth Capital Partners are leading the scheme on behalf of Reselton Properties Limited, which will see historic elements of the site retained and enhanced as well as upgrading the existing flood defences. In addition, a range of associated highway works will support the development. Recognising the importance of air quality in Richmond, the scheme aligns directly with Air Quality Positive London Plan Guidance. Significant ecological enhancement measures are incorporated, with the development achieving an overall Biodiversity Net Gain.

Waterman has been involved with the Stag Brewery redevelopment since its outset in 2015, providing multidisciplinary support spanning the site’s appraisal and acquisition through to the various planning submissions and beyond into the appeal process. As Lead Environmental Consultant, we coordinated the Environmental Impact Assessment and delivered the Environmental Statement, in addition to undertaking a wide range of in-house technical surveys and reports, including air quality, noise and vibration, ground conditions and contamination, ecology, arboriculture, flood risk and drainage, townscape, visual and heritage. Our specialists supported the lengthy public consultation process, working closely with the London Borough of Richmond Upon Thames and statutory consultees, including the Environment Agency, to secure their approval for the proposed flood defence works. In addition, we also provided expert witnesses throughout the successful appeal process via the Planning Inspectorate.

Focused on maximising the usable space available across the various elements, our structural design helped unlock the site’s potential, whilst also accommodating the retention of the historic maltings building, along with the bottling plant’s façade and the former hotel. In addition, our building services specialists provided M&E design and consultancy support for the scheme. With sustainability high on the agenda, our energy strategy incorporates all-electric heating and includes low carbon technologies such as air source heat pumps and rooftop photovoltaic panels.

Commenting on the impact of this significant development, Polly Clifton, Waterman’s Regional Director for Infrastructure and Environment, said: “After a decade, we’re delighted to see this remarkable scheme finally secure full approval. Throughout the various iterations, we’ve worked with the client, planning authorities and statutory bodies to overcome a series of challenges and arrive at a stunning, climate-resilient solution which will benefit both residents and nature for generations to come. Now, with the site’s future secured, we’re looking forward to seeing the redevelopment get underway and all the hard work come to fruition.”
