“Havering’s Greenbelt Under Threat: Will Sadiq Khan’s Housing Plans Turn Our Green Fields Into Flats?”

Nature or high-rises? Sadiq Khan’s push to reclassify greenbelt land could destroy Havering’s wildlife havens forever.

In a dramatic shift in policy, London Mayor Sadiq Khan could build tens of thousands of new homes on parts of the city’s green belt. Describing current protections as “wrong, out of date and simply unsustainable”, the Mayor now aims to increase London’s housing target from 52,000 to 88,000 homes per year — a move that has alarmed conservationists and local communities alike.

While Khan insists that brownfield sites will remain the priority, he’s opened the door to developing so-called “grey belt” land — green belt areas that are poorly maintained but equipped with transport infrastructure. Yet, many fear this is a slippery slope that will see protected landscapes bulldozed in favour of more tower blocks, traffic, and tarmac.

Havering: A Borough Under Threat

Havering, one of London’s greenest boroughs, is now seen as ripe for development. With vast swathes of farmland, green space, and semi-rural areas, it’s feared that Havering will become one of the first areas to feel the pressure of these new building plans. A proposed mega data centre in North Ockendon — set to replace a peaceful stretch of farmland — has already sparked local fury. The area is home to a range of wildlife, and residents have voiced strong concerns about losing their countryside to a ten-year construction project that benefits developers, not communities.

Figures show that Havering has already lost a significant portion of its tree coverage — dropping from 25% in 2018 to just 14% in 2024. Every tree lost takes with it an entire ecosystem, and as development increases, the birds, insects and mammals that rely on these spaces are being pushed out — with no sign of intervention.

A Concrete Jungle on the Horizon

Critics of the Mayor’s new plans argue that this is the beginning of the end for London’s natural landscape. Wildlife is declining. Birdsong is being replaced by the sound of diggers and cement trucks. Families who once chose Havering and other green belt areas for peace and tranquillity may soon find themselves surrounded by high-rises and office parks.

“How many enjoy waking up to trees swaying in a summer breeze or the sound of birds chirping away? Now London will wake up to another tower block, another cramped flat, another chunk of nature lost forever.”

The consequences of overdevelopment reach far beyond the aesthetics. Green spaces improve air quality, offer mental health benefits, and protect against urban flooding. Once they’re gone, they’re gone.

Are We Really Listening?

London needs homes — but does it need to sacrifice every last green space to build them? Communities across Havering and beyond are calling for smarter planning that protects what little nature we have left. As one resident recently put it: “There’s plenty of space to build if you look hard enough — but don’t touch our green belt.”

As the capital continues to expand, the question remains: do we want a livable London, or just a bigger one?
