The massing of the Ligonier Street Residence largely consists of a narrow, articulated rectangular volume that is bisected by a custom central staircase that links all four levels of the 3,557 square foot home. The natural sloping topography of the site allows for access to the home at the lower basement level from an alley condition at the downhill property edge and at the first floor from the public street at the uphill property edge.
