Kevin McCloud meets Marcus and Abi, who are building a luxurious off-grid family home deep in 20-acre woodland in Pembrokeshire on a budget of just £100,000. Granted permission through the One Planet Development planning laws, which are unique to Wales, they are armed with determination and timber from the surrounding forest. With no detailed plans, the project pushes the limits of design and endurance, and proves a raw, physical adventure that defies convention and challenges many of the ideas around what a home should be.
