The climate-focused redesign has been in the works for 10 years

One of central London's oldest and most famous public spaces is set to reopen on Monday following an "extraordinary transformation" that's been a year in the making.

The new-look Grosvenor Square boasts more than 150,000 new plants chosen to withstand rising urban temperatures, alongside 40 new trees, two new wetland areas, a café kiosk and 300 extra seats.

The project represents the culmination of a decade of planning aimed at turning the square's original simple lawn into a biodiverse haven, those behind the project said.

Until it was closed for works last year, the square was primarily made up of traditional manicured grass and intersecting tarmac paths.

Jamie Whitty-Lewis, chief executive of Grosvenor Property UK, said: "We've truly revitalised it into a really special garden now."

Landscape architect Chris Stanton says the park brings "countryside back into the West End"

He said the changes would help the West End adapt to extreme weather, adding: "We are feeling the summers getting warmer and the winters getting wetter.

"The planting here has a cooling effect, so you'll feel right now it's actually quite cool here under the shade of the trees."

Chris Stanton, the lead landscape architect on the project, described it as an "extraordinary transformation".

"When we started, the space was primarily just grass and tarmac paths.

"What we've managed to do is introduce a bit of the countryside back into the West End."

While the layout relies on modern environmental science, aspects of the landscaping draw inspiration from the square's original 18th-century design.

The new redesign has seen 150,000 plants replace what was largely open lawns

While the layout relies on modern environmental science, aspects of the landscaping draw inspiration from the square's original 18th-century design.

The opening ceremony was marked by a welcome address from the Duke of Westminster, a direct descendant of Sir Richard Grosvenor, who first created the space for Londoners.

Jamie Whitty-Lewis says the square has been "truly revitalised"

The duke said: "We wanted a place that basically people came and stopped and were able to relax and sit, find their own space, be curious throughout the square, and enjoy it."

He said he hoped the new design would offer a much-needed escape for people to escape the hectic atmosphere of central London.

"I hope the way we've designed Grosvenor Square presents an opportunity for people just to relax a bit and find their own little area to sit away and have a moment to themselves."
