A “landmark” southwest London home said to have helped inspire two of the world’s most celebrated modern buildings has been given to the National Trust.

The Grade II* listed house at 22 Parkside, Wimbledon, is regarded as one of the most “significant homes in British architectural history” and an early expression of ideas that would later shape the Centre Pompidou in Paris and Lloyd’s of London.

Overlooking Wimbledon Common, the house was designed in 1967 by British architect Richard Rogers and his then-wife, Su Rogers, for his parents.

Its radical design broke with the conventions of the time, featuring a single-storey layout, a bright-yellow steel frame, floor-to-ceiling glass walls and movable internal partitions that allowed rooms to be opened up.

The property has now passed from private ownership to the National Trust, which says the acquisition will protect “one of the UK’s most important examples of modern architecture for future generations”.

Ben Rogers, the son of Richard and Su Rogers, said: “22 Parkside is much more than a family home. It is one of the most important buildings my father and mother created – a place where many of the ideas that would go on to influence my father’s work and some of the world’s most celebrated architecture were first tested and explored.

“As a family, we wanted to ensure that this remarkable house would be protected, cared for and shared with future generations, rather than remaining a private asset.

“The National Trust brings the expertise, public purpose and long-term commitment needed to safeguard its future, while opening up its story to students, researchers and visitors.”

Ruthie Rogers, who was married to Rogers from 1973 until his death aged 88 in 2021, said her late husband “regarded public access to culture – whether architecture, art, theatre, music, or design – as one of the great aspirations in life”.

She said: “It filled him with such joy that the public would have access to this that was once private, a house that was a prototype for what he thought houses could be for all.”

National Trust director-general Hilary McGrady said: “We are profoundly grateful to the Rogers family for placing this extraordinary house in our care. Their generosity means that 22 Parkside will now become part of our shared inheritance, belonging not to a single family but to the people of England, Wales and Northern Ireland.

“This extraordinary gift will ensure that a building where world-changing ideas were born continues to inspire new generations of thinkers, makers and creators.”

The charity plans to host guided visits, educational partnerships and interactive, digital content at the house, with the aim it “becomes a creative and educational resource for schools, universities and other heritage organisations around the world”.

This Saturday, 22 Parkside will open to the public as part of London’s Open House festival.

Awarded Grade II* listed status in 2013, it is also sometimes known as the Rogers House or Wimbledon House.
