The adjoining semi had been added to a few years ago, with a first floor addition approved by Mosman Council before the current controls came into force.
I was able to match the extent of the adjoining semi in my design, and successfully argued for a non-complying floor space ratio well in excess of that allowed for the property. During the DA assessment process, I worked closely with the Council planner and heritage officer, modifying the design so it presented more as a roof form rather than a wall facing the street.
A split level to the new open plan ground floor extension allows for higher ceilings and a closer connection to the backyard. A double-height dining room with an open timber stair and bridge marks the transition between the old part of the house and the new. The bridge connects the new rear bedrooms to a rumpus room located within the attic space. The rumpus room is an unexpected but valuable space within the house. The owners have since sold the house, but potential buyers and the new owners have all appreciated the unusual but effective design moves throughout the design. I know this since quite a few of them have approached me to do their Mosman houses next!
