The most prominent feature of this project is the wooden tunnel arch that links art and history. The wooden arch creates a picture window of the castle beyond, uniting the art center with the surrounding historical scenery. The structure of the arch is made of steel, sandwiched with laminated wood sourced from Odawara, which provides the necessary fire protection and structural stability. In order to create harmony within the odd key-shaped site and neighboring building’s, as well as taking hint from the structure of a lantern’s bellows, this semi-cylindrical tunnel building is proposed.
