Squatters have moved in next door. 195 Mare Street, a Grade II* listed Georgian villa built in 1699, is the second oldest surviving house in Hackney. It’s been derelict for years: windows boarded up, front garden overgrown. Until, that is, one evening last week, when I saw people passing bags and boxes over the gate. The next morning, some sheets of A4 paper had been posted to the railings.
