Structural Completion: 3 Copper Square – A Landmark in Hybrid Innovation

PCE has reached structural completion on 3 Copper Square, a striking 14-storey, 239,000 sqft development that stands as one of the tallest structures in the UK to combine precast concrete and cross-laminated timber (CLT). Part of Related Argent’s Brent Cross Town development, PCE were appointed as design and build specialists by main contractor BAM Construction.

Delivered using PCE’s HybriDfMA Frame structural system, 3 Copper Square exemplifies how early integration, precision engineering, and digital-led delivery can achieve exceptional results — bringing together certainty, quality, compliance, and value through a highly coordinated DfMA (Design for Manufacture and Assembly) approach.

Hybrid by Design

At the heart of the project lies a hybrid kit-of-parts solution, comprising 13 repeatable components that seamlessly integrate precast concrete, recycled steel, and mass engineered CLT. Over 4,800 offsite-manufactured elements were produced, transported, and assembled using standardised build methodologies that prioritised safety, speed, and consistency.

Components were designed with M&E integration in mind — with pre-formed beam openings and raised floor zones ensuring perfect alignment and coordination, simplifying downstream installation, accelerating follow-on trade access for fit out, and improving overall project efficiency.

Precision Delivery

The HybriDfMA Frame system enabled a rapid, predictable build sequence — achieving an average of 11–13 days per floor with a core team of just 26 multi-skilled PCE operatives.

Every component was digitally tracked in real time using Ynomia’s advanced track-and-trace digital twin technology, providing 16-stage progress verification, comprehensive QA evidence, and a single source of truth for complete transparency across the project.

Through just-in-time delivery and precise sequencing, the systemised approach reduces site deliveries by 80%, minimising local disruption and allowing the adjacent Brent Cross West Station to remain fully operational - despite being just inches from the construction zone.

Sustainable by System

Sustainability was embedded throughout the design and build process, evidenced by its BREEAM Outstanding status. All concrete incorporated 40% Ground Granulated Blast-furnace Slag (GGBS), significantly lowering embodied carbon. The inclusion of CLT as a key structural component contributed to whole lifecycle carbon being 29% better than the GLA’s benchmark targets (excluding tenant fitout), while the overall structure achieved a 13% reduction against LETI benchmarks.

A Smarter Way to Build

3 Copper Square demonstrates how the HybriDfMA Frame system delivers more than structure — it delivers certainty, coordination, and confidence. By combining the best attributes of different structural materials, hybrid DfMA construction continues to redefine what’s possible in modern, sustainable, and digitally assured construction.
