An exhibition showcasing the brightest ideas on future garden cities opened today.

The International Garden Cities Exhibition display will run for six weeks featuring more than 200 entries from this year’s Wolfson Economics Prize which proposed ideas for new garden cities.

This will include Urbed’s winning entry for the £250,000 prize which suggests an imaginary city of 400,000 people called Uxcester, as well as children’s entries – including that of Letchworth schoolboy Ewan Frearson.

Visitors can delve into the entrants’ research, planning diagrams and illustrations, as well as key statements, quotes and powerful abstracts from their full submissions.

Chief Executive of Letchworth Garden City Heritage Foundation, John Lewis, said: “We are delighted to support the Wolfson Economics Prize exhibition and are pleased to be hosting it in Letchworth, the world’s first garden city.

“The Prize has stimulated a renewed interest in the garden city model, which we consider to be of continued relevance as part of today’s housing debate. The exhibition showcases a range of exciting new ideas and concepts.”

Simon Wolfson, founder of the Wolfson Economics Prize, said: “I am delighted that we have been able to stage this fantastic exhibition to convey the great ideas proposed by entrants to a wider audience.

“Anyone who has an interest in how we might build visionary, economically viable and popular garden cities will want to visit it.”

The exhibition first went on show in London after the prize was announced in September, and after being showcased in Letchworth it will tour to key Royal Town Planning Institute conferences throughout the UK.

Opening times are 10-5pm every Friday and Saturday, but other days are available upon request.
