Brief & Context:
A 400 sqm sustainable home to accomodate a large family of 6, designed to Passive House Principles. Floor plan arranged over 2 structures connected by its entry hallway, framing views to the garden & pool area.

Design Response & Description:
The home was completed in 2017 & one of the first homes in the western suburbs to be designed & built to passive house principles which include;

  • Constructed from a 170mm insulated timber frame.

  • Intello airtight membrane throughout.

  • Double Glazed uPVC glazing to meet Passive house standards.

  • All edges, corners, connections and penetrations designed & constructed to ensure no thermal bridges.

  • Heat Recovery Ventilation System- 75% of the heat from the exhaust air is transferred to the fresh air again by means of a heat exchanger.

  • Blower door tested ensuring Airtightness reading of a maximum of 0.6 air changes per hour at 50 Pascals pressure (ACH50), as verified with an onsite pressure test. Ensuring no uncontrolled air leakage through construction gaps etc…

  • Summer solar gain controlled with custom external timber solar louvres.

  • Rainwater harvesting with ingound tanks.

  • Large solar photovoltaics system.

  • The first homes in the Western suburbs to be built to Passive house principals. 

On completion; the home performed very well under an air tightness test; resulting in 0.6 ach@50pa which meets the requirement for passive house certification.  



Seamus worked with us to bring our luxurious, passive house design to life and we couldn’t be happier! A thoughtful Architectural design has brought out the best in our Nedlands block. Seamus incorporated as many aspects of sustainable healthy living as possible and we now have a beautiful home that is so comfortable to live in.

We highly recommend Seamus Ryan Architects to anyone seeking a custom architectural home and we look forward to working with Seamus again.
