Global delivery consultants and construction experts, Mace, have been appointed by Pegasi to lead the transformation of Fresh Wharf, a prominent 1980s building, into a high-performance, sustainability-led workplace overlooking the River Thames in London.

Located just minutes from Tower Bridge, the 11-storey building will be reimagined into 120,000 sq ft of premium workspace, featuring 25,150 sq ft of outdoor space, a new riverside café, improved public realm and a destination restaurant. Designed by Buckley Gray Yeoman, the scheme reflects a growing market trend to reposition existing buildings for a net-zero future while enhancing occupier experience.

Mace states:

'Fresh Wharf is targeting some of the highest environmental and performance benchmarks in the sector, including BREEAM Outstanding, WELL Platinum, NABERS 4.5 Stars and WiredScore Platinum with a projected whole-life embodied carbon footprint of 933 kgCO₂/m².

'In addition, approximately 50% of the building’s raised access flooring panels will be retained and reused, potentially saving up to 100 tonnes of CO₂. For newly fitted areas, low-carbon panels made from 86% recycled content will be installed. Each flooring panel is backed by an Environmental Product Declaration and a material passport, ensuring full traceability and enabling future reuse.

'Early-phase works are already delivering results with 30 tonnes of glazing removed from the original building being recycled through Saint-Gobain’s closed-loop glass system, saving a further 21.3 tonnes of CO₂'

Stewart Ward, Managing Director Fit out & Retrofit, Mace Construct explains:

“This project is about more than refurbishment; it’s about redefining what’s possible with existing buildings. At Fresh Wharf we’re proving that a 1980s structure can be transformed into a workplace that meets today’s highest sustainability standards, while delivering on design, modern occupier demands and creating long-term value.”

Scheduled for completion in 2026, Fresh Wharf is set to become a benchmark for sustainable workplace transformation in the City of London.

Jo Upton, CEO of Pegasi Limited commented: 

“Our long-term decision-making means that all the relationships we enter into have to be built on absolute confidence in quality, deliverability and resilience for what the occupier - or more accurately customer - will experience, not just on day 1 after practical completion, but in year 10. The creativity and ambition of this project has truly been a team effort, and we are delighted to be working with Mace as part of that extraordinary team”.
