THIS old house ain't built with concrete, this old house ain't built with stone.
What this house is built with is willow daubed over with a mixture of clay and straw put together by a team of keen volunteer builders using age old skills.
The project to build the Iron Age Roundhouse has brought together The University of Sheffield and Heeley City Farm.
It's part of a Heritage Lottery funded project Digging Our Roots, which is enabling young people at the farm to explore farming heritage from the past to present day.
And visitors to the farm were invited to get involved.
Alan Lewis, a second year archaeology student from the University of Sheffield who is president of the University's Archaeology Society, said:
"The project has already been extremely rewarding and exciting.
"On the one hand, from an archeological point of view, it allows us to consider the problems and solutions that would have arisen in Iron Age Society when producing one of these structures, and on the other hand it has allowed us to interact with the local community."
Dr Roger Doonan, a lecturer in the Department of Archaeology at the University of Sheffield, added: "We are delighted to be involved with the Heeley City Farm project and to be able to work in the community to share our skills and expertise.
"The Roundhouse is really starting to take shape now but there is still a lot to do.
"Already a lot of people have joined in to help and there really is the sense that as we build the Roundhouse we are also building relations amongst ourselves.
Sally Rodgers, project officer at the farm, said: "Eventually we will build a furnace and smelt iron in a way that hasn't been done in our Steel City for at least 500 years.
"We also hope to use it as a classroom for further heritage workshops at the farm."
When it is finished the Roundhouse will have a turf roof and be brightly painted on the inside providing more opportunities for people to get involved as the project progresses.
There will be another chance to help build it on Saturday between midday and 3pm.
Admission to the farm is free and there is no need to book.
