The project involves demolishing and deconstructing six buildings, retaining part of the existing basement and delivering a low-carbon, mixed-use development classified as a higher-risk building under the Building Safety Act. The ambition to reuse 2,000m³ of concrete from the original buildings adds technical and coordination demands. Detailed design, including significant contractor-designed elements, must support the Gateway submission process while integrating innovative structural reuse, energy-efficient building systems and high-quality amenities within a coordinated and deliverable scheme.

G&T is providing Project Management services, leading the project through the Building Safety Act Gateway submission process and procurement. Working with the project team, we have supported detailed design coordination, including contractor-designed elements, to help reduce client and contractor risk. The construction contract has been awarded and the Gateway 2 submission made. Demolition and deconstruction are underway, incorporating Piecewise Reuse of Existing Concrete in New Structures (PRECS), which enables recovered concrete sections to become part of the new basement structure.

The development will reuse 1,150m³ of existing concrete through PRECS and incorporate a further 850m³ of recycled aggregate into new concrete. Chilled slabs, natural ventilation and night-time purging will support operational efficiency, complemented by roof terraces, club rooms and enhanced end-of-trip facilities. Sustainability ambitions include BREEAM Outstanding, LEED Platinum, WELL-enabled design, a five-star NABERS rating and upfront embodied carbon of 542kgCO₂e/m². G&T’s ongoing Project Management is helping translate these ambitions into coordinated delivery while managing design interfaces and regulatory requirements.
