The four-bedroom eco-friendly pad is certified as a ‘Passive Plus House’ which means it has a minimal environmental impact with a design that requires little heating and cooling. 

Its floors, ceilings and walls encase a thick layer of insulation and all the glass doors and windows are double-glazed to keep heat in during winter and out during the summer.

There is also a cleverly-designed ventilation system that keep the humidity levels inside the home at a comfortable 30-60 per cent throughout the year.

What is a certified Passive House? 

‘Passive House’ is a design standard that achieves thermal comfort with minimal heating and cooling by using insulation, airtightness, appropriate window and door design, ventilation systems with heat recovery, and elimination of thermal bridges.

Originally developed in Germany in the 1990s, Passive House principles are now being used throughout the world.

Passive House standards are performance-based: they set performance targets to be met but do not dictate specific materials or products.

The Passive House Institute administers a certification scheme that allows a building to be called a Certified Passive House once it has met certain performance standards.

While the home is airtight, it can be opened up to let natural breezes flow through.

An airy L-shaped family room houses a kitchen, lounge and meals area, features a soaring double-storey atrium and opens out onto a covered alfresco decked area. 

The dining space features a servery window that pulls back to act as a private bar and a Hamptons-style kitchen with marble benchtops and island with a breakfast bar. 

On the ground level is a master suite and upstairs features three more cosy bedrooms as well as a home study.

Adding to the home’s energy efficiency is also a ducted reverse cycle air conditioner and heat recovery system with medical grade filters as well as a rainwater tank. 

Marketing agent Richard Cocozza of Upside Real Estate told realestate.com.au, he believed the home is the first Passive House Plus-certified house to be sold in Australia.

‘The way air circulates in the house, and the idea that everything contributes to the heating of it, from the oven to a hairdryer, and given how airtight it can be, it is very efficient,’ he said.

‘That’s why the air conditioner is so small considering it’s a 220sqm house. When it is closed up, the glazing, the insulation, the gas sealed windows to keep it air tight, all mean it doesn’t take much to cool it down or warm it up.’

It sold in April for $630,000 to a local woman looking to downsize drawing in a profit of $100,000 since it last changed owners in March last year.
