Mullum Creek designed by Habitech Systems is a new residential sub-division of an old orchard east of Melbourne in Donvale. The development sits beside Mullum Creek and has a strong environmental focus with all houses having to reach a minimum 7.5 stars energy rating and have a minimum of 4kW of solar panels.

The house is entered between two simple forms which define a strong circulation path through the building. This path cranks to the north as it moves through the house to maximise passive solar performance before terminating in a large east facing window which looks across Mullum Creek into a bushland reserve. As you move along the circulation path the floor level steps down whilst the ceiling remains high, opening up the rear of the house to the sky and garden.

The connection between the house and garden is a feature of the design with connected outdoor spaces to suit a variety of functions and seasons. To the north a large deck opens off the dining area for entertaining and enjoying the winter sun whilst taking in the great views the site offers. To the east a more private deck with a spa bath opens off the lounge and has views to Mullum Creek. To the south a sheltered and shady summer courtyard opens off the dining room.
