Dirrix won the Unfair Architect Award in 2018 with his sketch proposal “Four Walls”. For this design Dirrix got inspired by the historic and social idea behind fairs. The feeling of joy and social interaction that a fair brings is the base of this design. For ages, fairs took place in tents outside. When in the 19th-century fairs moved inside, people still used tents as decoration and so did Tomas. In a watchtower, showing the height of the building, the exhibition can be viewed from above.
