Deadline extension: Design a Cabanon

Enter the RIBAJ Microarchitecture Award in association with SterlingOSB by Wednesday 13th May

Le Corbusier designed and built the celebrated Cabanon in 1952 as a tiny vacation home at Roquebrune-Cap-Martin on the Côte d’Azur, retreating there every summer for more than 10 years. He claimed to have sketched it out in 45 minutes. At only 3.6m2, it is a miracle of compact design.

It shows Corb’s adaptability in design, creative use of space and aesthetic simplicity.

This is a competition for Arb-registered architects to design an external living shelter from a kit of parts mainly made from SterlingOSB. Winning and commended entries will demonstrate SterlingOSB’s versatility, strength and sustainability credentials.

Karl Morris, managing director of Norbord’s European Operations, said: ‘SterlingOSB is widely used in the construction industry. However, its aesthetics are often hidden in the building’s framework. We’re excited about the innovative designs that this competition will generate.’

The award winner and commended entries will be published in a special RIBA Journal Supplement in October 2015. The winner will receive a £2,500 honorarium. 

Deadline for entries: 5pm Wednesday 13th May 2015


Chaired by the RIBA Journal editor Hugh Pearman, judges include Andy Von Bradsky of PRP Architects, Philip Marsh of dRMM, Hanif Kara of AKT II, Cindy Walters of  Walters & Cohen Architects and Karl Morris, Norbord Europe. 

Judges will be looking for entries demonstrating how creativity, innovation and collaboration using SterlingOSB have delivered exemplar design and product solutions to achieve an original concept.
