Designed by Nicholas Groves-Raines of Groves-Raines Architects as an extension to the garden at Inverleith Terrace, Edinburgh, this sensually curving composting shed includes both a composting area and garden store.

The structure is constructed entirely from industrial concrete reinforcing bar using a technique similar to traditional willow weaving.

The shed, which was awarded The American Institute of Architects Excellence in Design Award, rises organically from the ground flowing upwards from its path edges, also constructed from woven re-bar.

Beyond the obvious ecological benefits the composting provides, the shed itself is eco-friendly.

The construction method minimizes impact on the ground and surrounding mature woodland since the vertical reinforcing rods are driven straight into the ground, eliminating the need for a traditional foundation.

Air and sunlight pass naturally through the weave, providing ventilation for composting while creating unique light patterns which change constantly throughout the day.

Further strengthening the connection between the structure and its wooded surroundings, there is also has a green roof  made from EPDM lined steel and planted with soft swaying grasses
