This week, on Building’s new Regenerate web channel, we find out how derelict Doncaster bungalows are being turned into attractive family homes using a moveable extension.

We see what it takes to make a Victorian terrace into an eco icon and how to refurbish a sixties estate while cutting carbon dioxide emissions.

Meanwhile our expert commentators cover everything from investment in regeneration to whether “zero carbon” has lost its meaning. And after an estate was deemed too violent for cats, we ask animal charities how to make housing pet-friendly.
