House under the Oaks

Juri Troy Architects as Architects

The house under the oaks is a low budget passive house concept developed for a small Austrian family.


With a minimum footprint and a wide outstretching wooden box on six columns it offers a living area of about 100 m2 on a plot of 913m2. The whole structure was done in prefabricated timber with ecological wood wool insulation of up to 60 cm. The interior is done in local wood as well, with a simple white-pigmented oil cover.


A heat pump with a ground collector, a controlled ventilation system with heat exchange and photovoltaic panels on the roof offer a perfect energy concept with a minimum of required external energy – which is provided by eco electricity.


The layout is arranged along the back wall, which accommodates a number of functions in the most compact possible way and allows for a door-less organization, this being a reference to the Japanese origins of the clients.


It is a made-to-measure prototype for affordable living on minimal energy standards in Austria.
