HS2 green space loss has become a decisive issue in the Holborn and St Pancras byelection, as residents demand answers over disappearing parks and playgrounds. The high-speed railway project, which began construction around London’s Euston station in 2017, has permanently swallowed 14,404 square metres of green space from the constituency. This loss has sparked outrage among locals who were promised replacements that have yet to materialise.
The Impact of HS2 on Local Green Spaces
When HS2 construction began, residents watched as parks and playgrounds gave way to diggers and rubble. Dorothea Hackman, a local campaigner, voiced the frustration of many: “They have to give it all back. But they are destroying it – so there’s nothing to give back.” Planning documents reveal that the Euston section of HS2 will permanently consume 14,404 square metres of green space, with additional areas temporarily closed off during construction. The biggest park under threat is St James’s Gardens, an 18th-century burial ground designated as a site of importance for nature conservation.
Political Fallout and Byelection Dynamics
The Holborn and St Pancras byelection, triggered by the resignation of former prime minister Keir Starmer, has become a referendum on HS2’s environmental impact. Labour and the Green Party are contesting the seat, with green space and housing developments taking centre stage. The government estimates that the full high-speed railway between London and Birmingham will open between May 2040 and December 2043, but locals are more concerned about the immediate loss of their environment.
Comparison of Green Space Loss
| Area | Green Space Lost (sqm) | Status |
|---|---|---|
| St James’s Gardens | ~5,000 | Permanently lost, replacement cancelled |
| Other parks and playgrounds | ~9,404 | Permanently lost |
| Total | 14,404 | No replacement committed |
Key Takeaways for Residents and Voters

What’s Next for HS2 and Green Space?
As the byelection approaches, candidates are under pressure to address the green space crisis. The Labour Party, which has historically supported HS2, faces criticism for not doing enough to protect local environments. The Green Party is capitalising on the discontent, promising to prioritise green spaces if elected. Meanwhile, residents continue to demand that HS2 Ltd honour its original commitment to replace lost green space. With the full railway not expected to open until 2040-2043, the fight over Holborn and St Pancras’s green spaces is far from over.
