Hadfield Residence

A subtle addition and renovation maintains the existing character of a century-old weatherboard cottage.

Summary

The Hadfield Residence is a century-old original weatherboard cottage in Mosman Park – one of the last undeveloped, non-heritage listed sites in the area.

During initial discussions, the Clients requested an additional children’s bedroom to their home, to maximise the livability and longevity of their residence. After some investigation into the existing house and the Client’s priorities, it was decided that a more optimum design would be the addition of a Master Suite and Study, and then the conversion of one of the existing Master Bedroom into the required children’s bedroom. This optimised the workings of the home, creating a clear children’s zone, and a new parent ‘wing,’ with associated livability, acoustic and energy efficiency benefits.

As a nod of respect to the existing housing form, the required addition was not a significantly more costly and destructive second storey addition, but a longer, narrower single storey design at the back of the existing residence. The traditional form and its value as part of the history of the area was thus maintained.

Optimising a north-south orientation, the design is a timber box, with large windows for solar efficiency.  A two-level design was utilised, with the bathroom and study section level with the existing house, and the master Bed sunken, grounded into the adjacent garden space.

Further works to the exiting included an updated kitchen and laundry, the addition of a scullery or wet-room, and a general update of the existing finishes, including painting and floor sanding.

The addition updates the spatial qualities of the home, ready for another century.
