This terrace house is located in a distinct small heritage precinct of inner Sydney. Within the confines of being a Heritage Item, the house has been extensively remodeled. The design has responded to a way of living sustainably and efficiently in an increasingly hotter climate. The use of external shutters, glass louvres, ceiling fans, insulation and skylights, provide the means to tackle the discomfort of some summer days and contain warmth in winter.
The principles in remodeling this house within the confines of its heritage status were:
- Stabilise structurally: The building was previously detached on the eastern side. By using this space on both levels, piles and underpinning were designed inserted to stabilise the existing building.
- Provide a building that performs efficiently and effectively in summer and winter: Louvres are used in every possible location to facilitate cross -ventilation.
- Design an integrated plan on the ground level to reduce the “boarding house” effect and introduce planting as integral to the building and visible from most of the house
- Provide Light and Ai
The project has contributed greatly to the environmental factors now governing how we design such as:
- Re using the existing structure.
- Slotted timber shutter keep the house cool in summer, warm in winter.
- The house is now well insulated.
- Windows and doors are smart glazed.
- Louvres and doors provide plentiful cross ventilation.
- Ceiling fans in every room of the building assist in cooling and circulating the air.
- Low energy, low cost heating with hydronic heating giving greater efficiency.
- A solar consultant advised that the roof area did not receive enough direct sun light to effectively use solar panels. This is mainly due to the built up nature of the location.

The brief: Off-form concrete house for two adults, four children and a disabled grandparent.
The existing Edwardian basement walls set out the new building and children’s courtyard. The new building is orientated with the site to the south, opening to the north and west.
The living-dining room is canted to allow high eastern windows drawing light into the children’s bedrooms below. All windows hang within the walls of the building or from the roof minimizing heat transfer and allowing them to be open during rain.
Skylights have been used in both parts of the building to capture and draw down light through the immediate floor and to floors below.
Concrete has been used as blades, screens, overhangs and as the deep gills of the building. Concrete shades and ventilates the building. In summer there is significant cross ventilation and upwards drafting. In winter, aspect and thermal massing help with heating.

The Brief: The original house was designed by architect Hugh Buhrich and was completed in 1961. When our work commenced, the house had been vacant for 2 years, it was riddled with concrete cancer, leaked badly in several places and had little or no north light internally at each level.
The new central courtyard allows north light at each level to the internal spaces and provided.
Our clients had lived at this address for 20 years. They had no wish to move. They did however want to take full advantage of their site on the slopes of Balmoral. As the landform allowed only one entry point to the site, the solution was severely restricted. We were unable to exploit the sloping land at the back of this small site.
We had to build on the existing limited platform. Our clients requested that the house “breathe” and perform environmentally in all seasons:
• The house has a northerly aspect.
• There is cross ventilation through the hole of the house assisted by two
• There is never a reason to cool the house and rarely any reason to heat it.
While our clients needed a lap pool, it was to function as a lap pool rather than a “display” pool. We located it on the eastern side of the house and below the rear terrace. It is out of view when on the terrace and from all other parts of the house. The pool is surrounded by vegetation
