In the Greek Colony neighborhood, representing one of the significant traditional architecture of Jerusalem, two dwelling units for an extended family, are added as an attached three floor town house to an existing building. The design of building elements, such as stairs, terraces, fenestrations and masonry details, interpret motifs of the surroundings. A new main stairway is inserted between the exiting building and the addition, serving the upper dwelling unit, to emphasize the connection between the old and the new. A stairway, serving the duplex main dwelling unit, wraps itself around the corner of the building, screening the south light into the house interiors. The masonry wall is punctured with fenestration’s of different sizes, which together with masonry details aims to create subtle harmony with the neighborhood.
