The Tenniscalator by David Tajchman may not have won the competition it was designed for, but it is definitely an impressive structure in anyone’s books.

Paris architect David Tajchman designed the Tenniscalator for a competition organized by the timber company Sodra. The Tenniscalator by David Tajchman is essentially a multi-level timber tennis center with five floors of courts stacked on top of each other. The facade features eye-like openings, which according to Dezeen, were inspired by the intricate wood knots found in timber.
