Ugly House to Lovely House with George Clarke

Fiona and Hugh hate absolutely everything about their home, except for the garden. They're won over by architect Greg Blee's modernist designs, but local planners aren't. Can they get the go-ahead?

George meets Matt and Kevin, whose 1930s home stands out for all the wrong reasons. Sitting alongside the elegant Victorian and Edwardian properties in south-west London, this three-up, three-down is ugly from the outside and even worse on the inside, with dark, dated and badly designed spaces. Architects Katerina Dionysopoulou and Billy Mavropoulos are brought in to make most radical transformation on the programme to date - but will their wildly ambitious poured-concrete extension prove too innovative for the owners?

Greg and Helen Watson have bought a home in one of the most expensive areas of Sheffield, South Yorkshire, but it's too cramped for their needs and needs renovating. What's more, their third child is due in 18 weeks and they are desperate to move in before then. Architects Howard Evans and Prue Chiles are given the job, but with the Covid-19 lockdown, the wettest month on record and some major design differences, the build is in danger of collapsing before their £120,000 budget runs out.

Back in 2017, George drafted in architect Chris Mason to help Wendy and Allan, whose Colchester home resembled a block of flats. They ended up with an enormous double-height extension and a Roman-style portico, but the ambitious scheme blew their budget and the project remained unfinished. George returns to find out whether they have managed to finish the property to the same exceptional standards.

George revisits Armin and Amifa, whose budget was sapped by their featureless suburban home's downstairs and an awful extension, leaving the upstairs unfinished. But is it now complete?

George looks back on some of the most radical transformations from across the series, including a 1980s property that was mostly garage, a depressing bungalow with fake-leaded windows and a house where the only access to the garden was through a bedroom.
