Operable Boundary creates a new field of openness, excavated from the lower level of an existing, traditional townhouse in Brooklyn Heights, New York.
Design concept and solution: Removing all of the servant functions from the house at both the garden level and the parlor floor liberates the space from its previous secondary status. The ground floor, originally the servants’ floor in this 19th century construction, is elevated to a new primary status, reorienting spatial and interpersonal relationships within the house. The traditional boundary between parlor and kitchen is opened through the excavation of a two-story space over the dining table, diminishing the sense of security and enclosure of the floor that would typically divide them. This upward extension of the ground floor into the parlor floor is amplified by the continuity of the stair connecting the private bedrooms to the rest of the house. The kitchen/dining space becomes an entertaining and family zone, equivalent in its activity to the formal parlor overhead. Open to each other as well as the garden, the joined spaces become an open field of occupation, abolishing conventional relationships of proximity and view.
