SOLUTION - Case Study: Pines Calyx

The Pines Calyx conference and events venue was conceived of as a carbon neutral catalyst for rural and urban sustainable development and for grass roots responses to the challenges of ‘peak oil’ and climate change. The building, in a stunning parkland location nestled in the White Cliffs of Dover, acts as the centrepiece in the ongoing development of a Centre for Sustainable Living. The building’s developers and designers are all members of the Carbon Free Group, a consortium working to make zero carbon living a practical and economical reality. The international team collaborated in delivering an award winning commercial building which demonstrates a successful fusion of historic construction techniques with 21st century technologies, design and analysis. 
  • Earth-sheltered and curved design with all the main walls being constructed in rammed chalk excavated from its own site.
  • One of the most stunning features is the use of ‘timbrel-vaulting’ (‘Catalan vaulting’), a centuries’ old method of construction successfully revived on this project. The technique delivers optimum sustainability and economics in creating the building’s shallow domes (no concrete, no formwork and swift to construct).
  • Natural ventilation systems and ‘virtual daylight’ lighting. 
  • Fully sustainable water management systems including reedbeds naturally treating waste water. Unique for an earth sheltered building is the minimal use of concrete with a very high percentage of the building being constructed from local waste and recycled materials resulting in the building having the lowest embodied energy of any modern commercial building in the UK.
  • First commercial building in the UK to operate in a fully carbon neutral manner with its overall surplus energy supplying other nearby buildings.
  • The outcome of the construction of the building has also been an overall enhancement in on site biodiversity and general enrichment of local community initiatives in alignment with the building owner’s local environmental and community focus.
