🌱Sustainability
BREEAM Excellent
100% of existing foundations retained + 60 existing piles + majority of frame = 2,500T of CO2 saved: lettable area doubled, while reducing upfront carbon by 35%
Over a typical 10 year lease, a carbon saving of 25% is estimated compared to leasing a new building
Water consumption meets highest BREEAM standards: rainwater harvesting helps reduce reliance on mains supply by 50%
Exposed thermal mass of concrete soffits instead of suspended ceilings reduces cooling loads + draws heat away naturally; ventilation at night in summer months pre-cools exposed concrete slabs, using less carbon
🥦 Wellbeing

Enhanced ventilation system with high grade filters + CO2 sensors = 100% fresh air with no recirculation
