But it’s all a rouse. It’s a piece of art work based around a very large mirror by Argentinian artist Leandro Erlich who was commissioned to make the piece by the Barbican centre.
If you want to go and hand off a building you can find this piece outdoors in Ashwin Street, Hackney, on a plot that has remained largely vacant since the Second World War.
This is the second piece from curator Lydia Yee who was behind the very successful Rain Room in the Curve Gallery in Barbican earlier this year.
To visit and take part in the artwork is free and you are encouraged to upload your pictures to Twitter and Facebook with the hashtag #dalstonhouse. The installation will open on Wednesday until August 4. Visit barbican.org.uk/dalstonhouse
