Dezeen is giving three readers the chance to win a copy of Mobitecture: Architecture on the Move, a book profiling structures that roll, slide and even float across water.
As well as tents and caravans, the publication – by author Rebecca Roke – presents modern houseboats, wearable structures and designs of the future.
Sibling's Walking Shelter and Kevin Cyr's Camper Bike appear in the book, alongside projects that experiment with material, colour and size.
Other featured designs, such as Angela Luna's Tent 2, draw attention to the current refugee crisis and migrants' urgent need for movable shelter when fleeing conflict zones.
Comprised of over 250 images, the book has been organised into eight thematic chapters – Human, No Wheels, One & Two Wheels, Three Wheels, Four Wheels, 5+Wheels, Sleds+ and Water.
Mobitecture: Architecture on the Move is published by Phaidon and is also available to purchase online for £14.95.
