🌱Sustainability

  • BREEAM Excellent: CO2 emissions 65% lower than similar developments

  • Over 1,000 photovoltaic roof panels generate 30% of annual electricity requirement

  • Natural light and ventilation philosophy: saw-tooth roof ensures even distribution and 3.7m floor to ceiling height maximises airflow

  • Minimum daylight factor of 5% to all regularly occupied areas – minimises artificial light

  • Developed on brownfield site: removed contamination from Brunel’s Great Western Railway complex


🥦 Wellbeing

  • Central atrium roof glazing allows sunlight to illuminate communal areas throughout the day

  • Ventilation ‘snouts’ (made from recycled beer cans) provide year-round wind-driven ventilation – whilst maintaining sky view

  • High-level acoustic control: suspended acoustic baffles control reverberation in open plan meeting space; doubles-up as acoustic screens to create enclosed breakout areas with pulley system


🎈Bonus feature

Bespoke carpet made from the Trust’s flocks of Herdwick sheep is used throughout. As well as being highly durable, the commission supports local farmers. You herd it here first.
