In March 2014, the residents of London’s New Era estate – a quiet little enclave in post-hip Hoxton – received a letter through the mail that landed like a bomb.

The flats they call home – and have done for years – had been sold to a faceless company based across the Atlantic: American pension fund manager Westbrook Partners. Within weeks, rents were raised by 17% – an instant burden on the civil servants, NHS workers and taxi drivers who call New Era home – but that opening gambit was just the start. With a shrug of the shoulders and a torrent of one-way exchanges, Westbrook have told residents, in no uncertain terms, that they can expect rents to rise to “market value” – a manufactured hike that will see a two-bedroom home rise from £600 a month to nearly £2,400.

It’s an unexpected twist for a story founded on good will. The New Era estate was built in the 1930s by the Lever family as a philanthropic venture to provide affordable homes to local workers. And that’s exactly what it’s done for the past 80 years, filling the void between state-funded social housing and a rental market that caters for white collars and cuffs.

Lindsey Garrett, an NHS care co-ordinator, lives on the estate with her 8-year-old daughter. She moved here when she was fifteen years old and her mum and dad still live in the adjoining block. Her auntie lives here; her great grandmother grew up here (“She was a local character, very well-known for all sorts of reasons”). When she walks around the estate people fling open their windows to say hello.

“I need my family, I need my friends. I’m a working single mum. Sometimes I work 45 hours a week, I need these people around me,” says Lindsey, who has been told she may have to move into a shared hostel if she can’t make rent and evictions go ahead in the New Year.

Lindsey is leading a campaign to keep rent affordable for existing tenants – the very people who grabbed Hoxton by the boot straps and pulled it up. “You wouldn’t have wanted to run through Hoxton when we first moved here, and we were a part of that change,” she says. “Hackney’s probably the centre of it, but this is a widespread problem across London. There’s no social housing. People can no longer afford to live in London.”

In a city that seems intent on fragmenting itself into solitary stories and vacant plots – as foreign investors see London’s housing market as portfolio opportunities not homes – the residents of the New Era estate, with charismatic Lindsey as their lead, are testament to what can happen to a neighbourhood when people take collective ownership of the area in which they live; when lives become intertwined and home becomes much more than the closed-off space of your own four walls.

Let’s hope they’re not the last.
