🟩 GreenBricks Building of the Week 🟩 One Angel Square

Huge green

One of the largest buildings ever to achieve such green credentials, this building is not about the environmental ‘add-ons’ or eco-bling wind turbines: sustainability is truly integrated into the structure.


Manchester, UK

🏢Building Details

  • 16-storey, 3-sided triangular structure; 325,000 sq ft

  • Completed February 2013; The Co-operative Group’s new HQ

  • 320-person ground floor auditorium

  • Nicknamed the ‘sliced egg’ due to distinctive shape


✍️Architects & Engineers


  • BREEAM Outstanding (95.3% = world-record at the time)

  • Fully glazed double skin façade with louvred panels – insulates in winter and facilitates ventilation in summer

  • Cogeneration heat and power plant uses biofuel and rapeseed oil, sourced from local Co-op farms = energy-plus building

  • Heat recovery from IT systems helps to heat building

  • Greywater and rainwater recycling systems for toilet flushing and irrigation

🥦 Wellbeing

  • Integration into public transport links, easily accessible by cycle routes; 105 on-site bike stands

  • Soaring open atrium flooded with natural light; reflected by white painted concrete reduces need for artificial lighting from 500 to 330 lux

  • Roof top and extended public area planting

  • Construction involved a high level of community engagement: 900+ people benefitted from on-site training, engagement with 1,000+ students, and 54% of workforce from Greater Manchester area

🎈Bonus feature

It’s future proofed against temperatures forecasted for 2050, meaning it can cope with a potential 3-5 degree increase and 30% more rainfall. The building becomes more efficient as global temperatures rise. Now that’s what you call forward-planning.
