A four-bedroom terrace in Saddleworth near Oldham with a tricky layout, an architecturally important flat in Blackheath in London and a dilapidated cottage without a bathroom in Treherbert in south Wales are all bought at auction. Two of the projects will be the developers' homes, and the three developments take from a few months to several years to complete.

Developers who have bought properties online all have to deal with the rising costs of building materials. They're working on projects in Wednesbury in the West Midlands, Dunvant in Swansea and Norwich in Norfolk.
