These architect designed acreage house plans deliver an award winning solar passive design across two floors. The acreage house plans create three independent living spaces and seven bedrooms across 400 square metres (not including external terrace and alfresco areas). The acreage house plans deliver a stable ambient air temperature across all seasons with little need for artificial heating via the Chazelles wood fuel firebox; that also provides boosts the 440 litre solar hot water unit during the cooler winter months. The single lock standing seam parapets to the bedroom wing of the acreage house plans discretely hide an optional 5.5kw photo voltaic array to reduce energy consumption. The acreage house plans achieves solar passive design principles through a generous allocation of north orientated glazing resulting in deep penetration of the lower azimuth winter sun for heat gain over the cooler winter months and exclude summer sun from the fenestration with generous skillion eaves. The highlight glass louvres create stack effect ventilation throughout the living areas to contribute to internal ambient air temperature during the hotter summer months – excluding the need for air conditioning in the solar passive design display home.

The acreage house plans feature operable Breezeway glass louvres to the underside of roof eaves on the northern elevation, generate cross ventilation for hot summer months for the cooling of the kitchen, living and dining areas. The acreage house plans boast direct sunlight spilling across the open plan kitchen/living/dining polished concrete floor during the cooler winter months, and thereby capturing the solar radiant heat from the direct sunlight during the daylight hours and releasing that heat from the building’s thermal mass throughout winter evenings. Incorporating operable windows and louvres to the living areas of the acreage house plans maximises the solar heat gain of the solar passive design during winter.

“We commissioned Threadgold Architecture for the refurbishment of our house in Dalkeith for both design and contract administration services. We were delighted with the design which Stuart tendered to a select group of local builders. We were also grateful for Stuart’s contractual understanding and attention to detail which kept the builder focussed on the desired outcomes throughout the building process. We are very happy with the renovations and the enjoyment we now get from our transformed living areas.”

“I was very impressed with the ideas that Stuart incorporated into the design for our family home in Perth.   Stuart designed a free-flowing open plan living space that perfectly suits our family of four. Stuart listened to our ideas and delivered the brief within the budget constraints.  My wife and I would be happy to recommend Threadgold Architecture as a business that still promotes the old values of honesty and integrity.”
