The Mill House I - Sustainable House Day

House Notes – The Mill House I

This project called for an inviting family home that invested a small budget carefully, in the areas that would provide the highest impact on the dwelling’s performance and amenity. Employing passive techniques, investments were made in thermal mass, insulation, air tightness and triple glazed, thermally-broken timber windows.

The result is an engaging three bedroom home with 8-star performance. Of particular interest are:

– Passive principles including north facing living and bedroom areas, strictly limited east/west glazing, and placement of garage to provide heat/wind block, high thermal mass, high insulation
Recycled bricks for feature elements and thermal mass
Triple glazed, thermally broken timber windows (U- Value 0.8, SHGC 0.5)
Thermally broken, solid core, fully air tight internal door between Garage and Dwelling
High level insulation to walls and roof
4000L rainwater tank, with 100% of roof feeding to tank
LED downlights generally
Mulched garden beds with low water plants
Ceiling fans to all living areas and bedrooms

All donations on the day will go to The Motor Neurone Disease Association NSW
