In Wiltshire, planning restrictions mean that primary school teacher Tara can only build temporary structures on a piece of land she inherited. This, and her desire to only use upcycled or recycled materials provides a challenge for Simon and his team.Using a reassembled corrugated metal shed that Tara acquired second hand, Simon devises a plan to create a tiny off-grid eco shed that will be a truly unique place to stay. But when he comes up with a plan to double the tiny living space, Tara remains unconvinced until a visit to The Quirky Tin Cottage, a similar B&B nearby, also made of corrugated metal.As the site has no water or drainage, and everything needs to be removable from the site, top carpenter Ian Tsang is given the tricky challenge of creating a compost loo from recycled pallets, and designer Zoe Hewitt skilfully uses Tara's love of vintage furniture and recycled materials to create a stunning mid-century themed interior.
