Architect George Clarke returns to unlock the potential of old houses. He meets teachers Simon and Sofie, whose 1930s Liverpool semi has lost its way thanks to a small kitchen and some dodgy interior design choices made by the previous owner.

George Clarke meets single father Rick, whose four-story terrace in Stratford-upon-Avon has just one room per floor and is totally impractical when his children come to stay.

George Clarke sets out to turn a part-Victorian, part-Georgian and part-medieval house in Wales into a modern family home - but the biggest challenge comes when it turns out co-owner Oona does not like kitchens.

George visits a 300-year-old house with too many loos. And in south London, a mini 1930s bungalow with a tiny lounge needs clever design solutions.

George takes on an Edwardian home suffering from an extreme case of 1970s wall-to-wall paneling. He also tackles a mock Tudor cottage in Hastings.

George works on a stripped Victorian terrace in Plumstead, looking to create a new layout that won't break the bank. He also visits a magnificent villa near Liverpool.
