Development Summary
An existing period terrace home is extended by a prefabricated two-storey modular home. The compact design accommodates a 3 bedroom home on a very small inner urban site (approx 125m2) without compromising access to daylight and natural ventilation. A green roof will be installed that greatly enhances the site’s permeability and ecological value.

Selection of key sustainable design commitments
1.0 Indoor environment quality
- A central courtyard ensures the ability to cross ventilate the entire home and draws an ample amount of natural light into the ground floor kitchen area.
- It provides good access to daylight and natural ventilation to a bedroom of the existing period home.
2.0 Energy efficiency
- A 1.5m eave will provide sun shading to the west facing kitchen sliding doors. In mid-summer, the extensive overhang will provide full shading up to approx. 4:30pm.
- Deep vertical fins in front of the west-facing 1st floor window not only provide a privacy screen to minimise overlooking into surrounding properties but also extensive sun shading to reduce summer solar heat gains.
3.0 Water resources
- Water efficient fittings will be installed (showerheads: 3-Star WELS, taps & basins: 5-Star WELS, toilet cisterns: 4-Star WELS)
4.0 Stormwater management
- A 2,000L slimline rainwater tank, located between the home extension and the neighbouring dwelling provides water for 2 toilets and a washing machine.
8.0 Urban ecology
- A green roof will cover the entire extension, significantly enhancing the urban ecology and permeability of the site.
(Bill McCorkell):Sustainability for ArchiBlox is not just about our designs and build buildings it is a holistic sustainable business practice incorporated into our everyday business from our building techniques, staff members to our local community. We have been proactively evolving our sustainable design and building methods for several years and have an ongoing comprehensive sustainability program.
- We minimise materials used through smart design and clever construction with sustainable modular design and sophisticated pre-fabrication.
- Reduce toxicity used in our homes (through the use of natural materials and Non-off-gassing materials) We design our homes and work spaces to maximize the air flow and natural light that keeps spaces bright and clean.
- Minimise waste by considering raw material dimensions in the design of our modules such as the size of a timber, plaster sheets and steel lengths
- Double glazed argon filled windows are used to capture and maintain stable internal temperatures
- We integrate thermal mass into the home to stabilise and store internal temperatures
- Highly insulated construction techniques to provide a minimum 7 star energy ratings
- Light coloured roofing materials to reflect radiant heat from the sun
- We reduce our carbon emissions through contributing to tree planting schemes for every house built
- Use locally sourced timbers and materials and try to use local suppliers wherever possible
The design needs to take into consideration the end use and type of green roof being proposed. The structural elements and loadings of the roof then need to be engineered to accommodate the additional weight of the roof. The roof has been fully tanked with two layers of bitumen membranes and an oversized box cutter was installed to ensure efficient drainage.
- Increased vegetated areas of the site
- Improved insulation
- Reduction of impact to the storm water system
- Noise and sound insulation
The roof is like any garden and the water requirements are dependent of the type of vegetation planted, and like all garden beds the need for weeding is required.
