Grand Designs: The Streets - Season 1 Episode 5 -

Kevin McCloud follows two more self-build plots in Oxfordshire. Engineers Sean and Dianna are building an `upside-down' house, with bedrooms downstairs so they can enjoy the views from their open-plan first floor. But an unexpected offer to work abroad upsets their carefully laid plans. Meanwhile, Garrie is building the largest house on the street, packed with expensive technology for wife Sue, who is disabled and has mental health issues.
