The Beehive: Derelict newsagent's shop to tiny home

The Beehive is the work of architect Clare Williamson and her husband, structural engineer Oscar Baldry who run design and architecture practise CandO. After a period of travelling abroad and living in a van, they turned the former 1960s shop in Shrewsbury into a 42 sqm tiny home. The one bedroom and the kitchen are on the ground floor and upstairs is a living and working space, with a a small terrace on the front. Here's what they say about it:
This project was self built by CandO to Passivhaus principles. The aim was to create a quirky, super energy efficient home at an very affordable cost. The dark timber cladding and the form of the first floor extension reference Shrewsbury’s black timber medieval architecture in a contemporary way. The timber framed extension is designed to be a lightweight breathable construction above the existing cavity walls below. 
The arrangement of large openings, living areas and a small roof terrace to the south within a well insulated, airtight envelope follow the principles of Passivhaus design. In addition by use of mechanical ventilation with heat recovery and minimising thermal bridges, the buildings heating costs are reduced to a minimum.
