Sustainable Design
Considered, informed design

We believe sustainable design does not have to be strawbales and recycled wellies, although we like them too. We take pride in our extensive and up to date knowledge of locally sourced and recycled materials and sustainable construction methods. We are always happy to give suggestions and advice on how to achieve the contemporary space you want with minimal environmental impact.

Shown here, our garden ‘The Rain Chain’ at the RHS Hampton Court Palace Flower Show in 2009 won the award for ‘Best Sustainable Garden’. It dealt with issues of flash flooding by using permeable surfaces, a green roof and a rain garden using plants tolerant of a wide range of soil conditions.

Green Roofs
Green roof and rain chain

We specialise in the design and planting of green roofs.

  • Award–winning green roof design service, taking into account pitch, aspect, weight loading, local climate and aesthetic requirements
  • Green roof planting design service, taking into account roof aspect, microclimates, substrate, local biodiversity and rainfall to ensure the success of the plants
  • Sourcing and supply of materials/plants for DIY green roofs
  • We work with teams of professional, experienced contractors to install the green roof system if required

Green roofs can be added to existing sheds, garages, flat or sloped roofs, bus shelters, bike shelters, car ports… see the Media section for a free information sheet.
