Kevin McCloud follows more of Britain's most ambitious self-building projects, as intrepid individuals attempt to design and construct the home of their dreams. In this first edition, Kevin meets former army captain Justin, who has spent £1.8million on an abandoned neo-Gothic cemetery keeper's lodge and adjoining ex-council toilet block in south-west London. Justin's vision is to restore the lodge but demolish the ugly toilet blocks and replace them with an enormous luxury ground-floor extension, with an added moat and a giant basement with a swimming pool - all just metres from the nearest grave.

Nathan and Amye are building a cathedral-like home modeled on local Dutch barn houses with a sleek twist and a 5000-tile armadillo roof. But the pressure mounts for project manager Nathan.
