Prefab Eco House

  • open plan passive solar design
  • 2 self contained living spaces
  • 226 sqm ground and first floors
  • 79 sqm alfresco and terrace
  • 6 bedrooms
  • 3 bathrooms
  • 5 carbays

This architect inspired design plan creates an affordable prefab eco house which is ideal for sloping sites, alfresco entertaining and enjoying picturesque sweeping views. The design plan achieves 226 sqm of area across ground and first floors. The design plan generates a prefab eco house ideal for short term stay accommodation by creating two separate first floor living areas, and the design plan’s pre fab and modular design techniques, generate a short building program. The design plan of this prefab eco house is also ideal to overcome the costs and logistics of building in remote or isolated locations with its patented prefab footing system.

The design plan elevates the prefab eco house above the sloping site and strategically planned around a centrally located and bi-parting stair – creating five carbays and 10 sqm of store at ground level. The design plan of the prefab eco house incorporates a double glazed and sound insulated timber pivot door to separate the two adjacent first floor living areas. The design plan juxtaposes two independent first floor living areas serviced by a kitchen and scullery. The five car bays to the lower ground floor service each self contained living area of the prefab eco house. The design plan lays out bedrooms and wet areas either side of the stair on the ground floor, to discretely service the three bedrooms of each self contained living space and maximise sweeping first floor views from the two living areas of the prefab eco house.

“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.”
