Stag Brewery

The historic Stag Brewery site in Mortlake—vacant since 2015—presented a complex challenge. Spread across 22 acres, the brownfield site required remediation, flood‑defence upgrades and enhanced pedestrian and cycle access to the River Thames, while retaining its heritage Maltings building. Reselton Properties aimed to deliver a new neighbourhood comprising 1,068 homes (including more than 80 affordable), a secondary school for 1,200 pupils, offices, hotel, retail, cinema, restaurants and a community football pitch—anchored by strong sustainability and ecological enhancement goals.

G&T is providing Cost Management services throughout  development. We prepared a revised cost estimate to support planning submissions and viability appraisals, ensuring budget certainty across residential, education, leisure, hospitality and infrastructure elements. We have also managed procurement strategy, monitored costs through planning and fire‑regulation redesigns, and advised on off‑site highways works to mitigate traffic impacts—while upholding Air Quality Positive and Biodiversity Net Gain commitments.

With planning approval secured, the Stag Brewery masterplan is ready to progress on site. The scheme will deliver over 1,068 homes (80+ affordable), a new secondary school, community football pitch, retail, cinema, offices, hotel and green public spaces, linked by safe, well-lit routes to Mortlake Green and the Thames. G&T’s financial stewardship ensured robust cost control and technical rigour, supporting a sustainable, multi‑generational neighbourhood rooted in local identity.
