Grand Designs returned earlier this month with one of the biggest houses ever to feature on the programme
The £1.5 million single-storey house in Colgate, West Sussex, was the vision of Clinton Dall and Brighton designer Desmond Hammond.
With four bedrooms, the steel and concrete house was built in secluded woodland on the site of an old two-storey house.
The concrete base is 60m in length and big enough for seven normal-sized houses, and covered in grey pocelain tiles. To the south there is a glass wall, and to the north a wall made of white porcelain tiles each measuring 1.5m².
13,000m² of materials were used in the project, including the steel frame - enough to build ten new homes.
The house includes a double integrated garage, utility room, gym, games room, sauna, and open plan living area, with four bedrooms overlooking the 15m outdoor swimming pool,
