Project Year: 2013 – 2015
Project Cost: $450,000

The owners of the northern half of the Rose Bay I semi were impressed with the results on the other side of the fence. They approached me to collaborate with them in designing a single storey addition to their house.

The existing interior was gutted and renovated throughout, with new bedrooms, bathroom and conversion of the existing patio into an ensuite. A timber and steel garage freshened the dated front, and also provides visual and acoustic privacy from the Old South Head Road traffic.

Towards the rear, the living room extension opens out the house to its backyard, previously blocked off by an existing laundry. A skillion roof slopes up from the existing gutter towards the rear, creating a high ceiling with tall bi-folding doors and a highlight window.

As with Rose Bay I, a Sydney Water sewer main passing through the site was taken into consideration during the design process. Unlike Rose Bay I, where a relatively simple encasement of the sewer was sufficient to comply with Sydney Water requirements, a further complication arose with an access manhole being required.

After the initial annoyance and frustration, I managed to turn the challenge posed into a positive feature, with a small light well stepping around the manhole. The light well brings north light into the house, allowing for a planted courtyard outside and a study nook inside.
