Grand Designs 26x1 - Worthing

Kevin McCloud follows more of Britain's most ambitiousself-building projects, as intrepid individuals attempt todesign and construct the home of their dreams. Howard and Sarahembark on their most ambitious building project yet - a sleek,angled, metallic floating home on a tidal estuary nearWorthing. Designed to look like a boat, and nestled within anidiosyncratic houseboat community, the structure will sit onan experimental prefabricated polystyrene slab to deal withhigh tides alternating with hours sitting in the mud. It's ahuge experiment, with £385,000 to spend over an 18-monthschedule, especially as they'll be doing much of the workthemselves and finalising the engineering as they go. Thingsget off to an agonisingly slow start when it takes months topainstakingly remove a condemned D-Day landing craft from theplot before they can even get started and the constant tidalshifts that disrupt any construction creates a real recipe fordisaster.
