Polish studio Mode:lina Architekci built a tank out of cardboard tubes to make this pop-up shop for Swedish watch brand TRIWA (+ slideshow).

Located in Poznań Plaza shopping mall in the city of Poznań, Poland, the Tube Tank was designed by Mode:lina Architekci to be low-cost and quick to construct.

The tank is built from over 900 cardboard tubes and held together with brightly coloured ratchet straps.

The architects settled on the material first and then discovered that a tank shape would be a simple and secure way to piece the cardboard together.

"When we did some experiments with strapping the tubes with ratchet straps, the most stable construction looked like a caterpillar tread – we decided to follow this look," architect Jerzy Woźniak told Dezeen.

The display cabinets for the posters and watches are made from chunky chipboard panels.

TRIWA sales assistants stand inside the tank to sell watches to passing customers.

Cardboard tubes have popped up in a few projects on Dezeen, including an installation in a London department store by Nicholas Grimshaw's studio and a Japanese boutique made of hanging cardboard tubes.

Previous projects by Mode:lina we've featured include a stark police station interior and a London soundscape played through tangled pipes, which we filmed as part of our Dezeen Platform micro-exhibition.

Here's some more information from the architects:

Once again mode:lina accepted a challenge, to create a temporary store for Swedish watch brand TRIWA. Goals, similar to previous year, were:
Use of renewable materials - Low cost
Speed of constructing
But above all, to further increase global brand awareness.

Previous cooperation between the two exceeded by far client’s expectations – pictures of the store were published around the globe, both online and offline.

Once more, designers decided to use a very well known raw material – paperboard. Only this time it was rolled into tubes. Over 900 of paper tubes, wrapped with ratchet-straps around cabinets built from raw OSB wood panels. That's how the Tube Tank was born. Meet Triwa Pop-Up store! See you at Poznań Plaza mall (Poland)!
