High on a hill to harness the Yallingup countryside – an eco house that epitomises an off-grid lifestyle.
This award winning project was designed as an energy efficient eco house for a young growing family who had purchased 120 acre farm in Yallingup. This eco house embodies the clients’ ideals to live sustainably and off-grid with the brief demanding the home be power self-sufficient and incorporate passive solar design principles to reduce energy consumption. This south west architecture optimises environmentally sustainable design principles by being sited at elevation to take advantage of views, cooling breezes and is surrounded by citrus, nut and pomme fruit orchards set out to permaculture principles as part of the design brief. It achieves passive solar design through a generous allocation of north facing glazing and end folding glass doors.
During the warmer south west days, the owners open the Breezeway glass louvres to the underside of roof eaves on the northern elevation to generate cross ventilation and cool the kitchen, living and dining areas. Throughout the colder days of a south west winter, the occupants close the operable windows and louvres to enjoy direct sunlight across 85% of the living floor space. The honed concrete floor to living areas captures the radiant heat from the direct sunlight during the daylight hours and releases the heat through cooler south-west evenings.
The specification for the house incorporates materials that have a low embodied energy with rammed limestone to the south elevation for heat retention and Corten steel cladding the west elevation. The kitchen perimeter benchtops are fabricated from 316 stainless steel and are framed by a white coloured back glass splashback. The island bench is made from a complimentary Essastone selection. Cabinetwork doors and drawers share laminate and a two pack epoxy finish while Blum Adventos lift overhead cupboards are situated over the southern slot window to the rammed limestone; doubling as the cabinetwork splashback. Artedomus tiles and Astra Walker tapware are specified throughout the kitchen and wet areas.
The house boasts complete power self-sufficiency with a 5.5kw photo voltaic array discretely hidden from view behind the single lock standing seam anthra zinc clad parapet. The house’s sustainable design credentials are further endorsed through rainwater harvesting and a potable water storage capacity of 550 kilolitres. The house’s green building benefits are also enhanced through incorporating a 440 litre Solarhart solar hot water system boosted by the Chazelle Chimneys wood fire box. The fitout has reduced the embodied energy of the build by utilising locally sourced recycled jarrah and sheoak hard wood species with a high natural resistance to white ants. The brief included an edible landscape surrounding the house comprising of dwarf coffee trees, feijoa, papaya, pineapple and tamarillo trees laid out to permaculture principles.
