The story of one man's heroic attempt to fulfill his childhood dream and bring back from the ruins an incredible castle set in one of the most beautiful landscapes in Ireland. Kevin McCloud meets more people trying to build dream homes, beginning with Sean Simons, who bought the ruins of Cloontykilla Castle in the Irish county of Roscommon with a view to using them to create a spectacular mock-16th-century home. However, the outlandish plans - including jacuzzis in the battlements and water-spouting gargoyles - have Kevin worried the project could become a garish nightmare, and his scepticism increases when he realises Sean has not consulted an architect. Disaster seems to be looming as the contractors get frustrated and planning regulations are ignored, but somehow things begin to slowly take shape - until a national economic crisis plunges everything into chaos.

Kevin McCloud marks the 100th episode with one of the programme's most ambitious projects to date. Leigh Osborne and Graham Voce want to convert and extend a landmark 150-year-old water tower in central London into a luxury home. Grade II-listed, derelict and with 6ft-thick walls, it's a huge challenge for the pair, who also plan to build two structures at the base - a lift shaft connected by a series of glass tunnels, and a modern living space. The result will be a four-bedroom property over nine floors, complete with a room at the top offering spectacular 360 degree views across the capital. The tower, which is located directly above London Underground's Northern Line, was originally built for Lambeth Workhouse in 1877 and became a Grade II listed building in 2008.
