I saw this today on freshome. If you are wondering is this is for real, it is. This is the Keret House by Jakub Szczesny of Centrala and it is really going to be constructed between 2 buildings in Wola, Poland. The house will have room for a bed, small kitchen area and work space. Maybe we will see it in Apartment Therapy's Small Cool house contest one day!
Yep, the plan is to put it there.
This is what the house will look like inside. Very small but maybe you're the type of person who can handle tiny like this. It really is a great idea to make use of unused space.
The stairs will be remote controlled retractable stairs.
