The brief was to design and build a passive house standard farmhouse that would allow two families to enjoy the home, yet maintain their own privacy. In addition, it had to be high quality, low maintenance, with exceptional levels of energy efficiency. The client wanted to incorporate modern architecture, design and materials, to create an exceptional living space.
A stunning contemporary passive house standard farmhouse
The Beattie Build System provides this bespoke farmhouse with very high levels of insulation and eliminates cold bridges within the structure. The house benefits from a mechanically ventilated heat recovery system (MVHR) with an integral air source heat pump. Intake air is drawn through an underground 50m ‘earth tube’. It is pre-heated or cooled naturally. Domestic hot water is heated by two individual air source heat pump electric cylinders run during the day while the sun is out and stored for night-time use. There are even three wood burners installed, more for aesthetics than as a heating source, with airtightness maintained due to the air flow channelled via a separate underfloor pipe.
Bathrooms and kitchen areas have under floor electric mats using electricity generated from a large photovoltaic array installed on the adjacent farm building roofs. This is a highly sustainable working building, which is rated carbon negative.
The Beattie Passive Build System has transformed our ‘grand design’ vision to a living, breathing reality. Nestled within the family farm, our home blends seamlessly into the rolling landscape and will be extremely cost efficient for years to come.
