The late 1800's stone house is listed under North Sydney Council as being a Local Heritage Item. Over time various additions had taken place to the rear, with the front section remaining intact.

The brief was to facilitate modern living and respect the heritage significance of the building.

The new Kitchen and Dining area was built as a modernist addition to the rear enclosing but expressing the earlier Kitchen. The terrace also formed the roof over the garage. The roof was kept back from the stone wall to the north to allow the play of light down the surface, giving strength to the wall. The expressed edge of the terrace aligned with the string course of faced stone at the first floor level.

Resolving the vertical and horizontal access routes through the building was a significant turning point in the design. After investigation of the foundation space under the Kitchen and the rear gallery the decision was made to construct the new stair within the existing Kitchen expressing the changes in quality of the stonework, leaving the wood fired fireplace and hearth. The stair was floated free of the walls to provide an up-light pelmet showcasing the stonework. The first floor ensuite has been constructed within the Sitting Area. Importantly the fabric of the room has been retained, including the fireplace and mantle.

The additions undertaken retained the heritage significance of the building, integrating modern facilities. The external stonework was restored and replaced as required.
