Is this the coolest dog bed ever?

What do you get when you cross two 3D printers with 1019 tennis balls?

If our dogs were able to tell us what their dream house would look like, we imagine it would look a lot like this.

A modular structure that is made almost entirely from tennis balls, and which can be made as small or as large as you like – no tools required.

The design, called Fetch House, was the brainchild of Dallas-based architecture and design firm CallisonRTKL, who created it to raise money for the SPCA of Texas.

The clever dog house won Best of Show at the Bark + Build Pet House Design & Build Competition, raising $1600 for the shelter.

Fetch House is an interactive shelter for the modern dog. The 3D printed modular support structure can house over 1,000 tennis balls, making it both easy to assemble and versatile – as gaps can be left to allow for more light and ventilation.

The dog house uses technology to promote an active lifestyle, and it explores how digital design and fabrication can change the way we think about how we build and live.

The lightweight dog house is designed as a kit with the modules snapping together – no tools required – and the versatile structure can also be made smaller or larger, depending on the size of the dog (and depending on how many tennis balls you have!).

The balls stay in place by compression but can easily be pulled out for a game of fetch. When play time is over, the balls can be returned to the walls of the dog house.

'We saw the competition as an opportunity to test our ideas and show that a bespoke design could be created and easily made available to the public via desktop 3D printing,' says Brendan O’Grady, a vice president in CRTKL’s Dallas office. 'At CallisonRTKL, we’re always trying to find ways that technology can aid us in the process of exploring new designs and innovative solutions.'

'Ultimately, we would like to create a platform that allows individuals to customise the doghouse design based on their specific dog,' says O’Grady. 'They can then download the digital model and use a local maker space or their own desktop 3D printer to fabricate the structure.'

The second prize for best overall design went to the White Paw design by design firm GFF, who won the “Hot Dog” award.

The 'Teacup Pup' award went to Pawsh Retreat design by GSO Architects for the best design for small dogs. This doghouse reflects edgy contemporary architectural design and utilises trendy finishes, while allowing for functionality and easy maintenance.

Taking home the award for cat condo, the Felix Helix by Omniplan was voted the best design for embracing the active, agile and curious nature of cats. Three helical molded plywood fins gracefully encircle four rotating wood platforms, with holes for access and play, with leave-outs for removable fabric inserts.
