The bulk of the house was erected in just four days
An artist has built a "click-together" home in just 10 days to challenge people's views on architecture.
Prof Wolfgang Weileder, of Newcastle University, erected the exact replica of a Georgian terraced house in the Sunniside area of Sunderland.
The main construction, using light weight concrete blocks, was completed in four days - a procedure taking up to three weeks using traditional bricks.
It is part of a programme of public art being developed by Sunderland Council.
The installation, part of a project called Fold-Up, will be on show until 3 August, after which the building will be dismantled and recycled.
The replica was made using continental construction techniques, where blocks click together like Lego without using cement.
The 43-year-old professor of contemporary sculpture said: "I think the focus of the project goes beyond the pure aesthetics of the structure.
"I would like to think Fold-Up will inspire people to take ownership of where they live and be more critically aware of their built environment.
"I hope that people appreciated the experience of watching the house unfolding before their very eyes, a unique occurrence that very few people have ever witnessed before."
