We are a couple of very environmentally conscious designers and builders. We wanted to build a thermally efficient building that is also healthy, using renewable products where possible to minimise the carbon footprint and to maximise affordability.

With this project we wanted to achieve high levels of operational energy efficiency and avoid energy costs, as well as creating a building fabric that has low embodied energy and creates a healthy home.

We used strawbales and lime-based plaster in order to have ‘breathable’ walls. The lime-based plaster can absorb moisture and allow water vapour to move through the building fabric. Using strawbales reduced the cost of the build, providing high-righted insulation as well as wall infill.

Double-glazed timber-frame doors and windows reduce the amount of heat gain/loss through the glass. The location of the openings have been designed to maximise cross-flow ventilation.
