Artists are transforming a building site into a model development.The site in North West Cambridge is being turned into a scale model of the 3,000 new homes an shops which will soon occupy the site.
It's being led by artist Karen Guthrie, who was inspired by the archaeological dig currently taking place on the site.
It's being built from an ancient building material known as cob - which is a mixture of mud and straw.
The model represents phase one. It includes a representation of the primary school.There's also a supermarket and community centre.
There's an open day to see the cob project on Saturday.
You can find more details about the project here.
