🟩 GreenBricks Building of the Week 🟩 The Ridge

Breathing green

Awarded 6-star Green Star Design, The Ridge is 1 of only 9 other offices to achieve this to date. Its progressive design elements raise the bar on new developments across Africa. With energy performance and natural ventilation fully integrated – this is a building which literally breathes on its own.


Cape Town, South Africa

🏢Building Details

  • 4-storey, 3 basement levels for parking

  • 1st building in South Africa to employ CLT structure

  • Completed in 2020; rented by Deloitte


✍️Architects & Engineers


  • CLT structure reduces overall CO2 footprint by 60 tonnes

  • Building operates in 2 modes: conventional sealed air condition or passive naturally ventilated mode – BMS traffic-light system advises when to open windows

  • Thermally activated building system (TABS) in floor slabs regulates temperature by heating and cooling building mass through embedded water pipes: potential to naturally ventilate 80% of year

  • Roof harvests solar photovoltaic power with placement of PV panels = building generates 25% of its energy

🥦 Wellbeing

  • Zigzag-shaped façade allows occupants to enjoy maximum natural light while minimising heat gain

  • Internal atrium conceptualised as a street, facilitating staff movement and informal connections

  • Interior plantscaping and planted balconies, encouraging employees to sit less at desks

  • Tea and coffee hubs interspersed throughout the building allowing staff to decompress and interact

  • Intelligent lighting with smart controls emulates body’s circadian rhythm by changing tone throughout the day

🎈Bonus feature

12,000 ‘ecobricks’ are used within its structure: one of the very first buildings to do so. These ecobricks are made from plastic waste-filled PET 2l bottles, in other words, upcycled Coca Cola bottles dumped in Cape Town. This has saved approximately 24,000 litres of concrete, whilst removing 9,000 tonnes of non-biodegradable plastic pollution. Big win-win.
