The 20/20 House - Passive House Bayswater North

The house is constructed using Structural Insulated Panels (SIPs) from Fenster and Panel, providing superior insulation and airtightness. The triple glazed uPVC windows from Bluesky Windows ensure that the house is energy efficient and thermally comfortable.

Certified as a Passive House, the 20/20 Passive House is a double storey home with a compact footprint. Downstairs, the open kitchen living dining area is spacious with a high raked ceiling and exposed timber beam over the living area. The dining area opens up to a fire pit area, perfect for cozy gatherings. The living area at the rear opens up to a spacious deck for outdoor dining and a BBQ area.

The tiny home studio at the back of the house offers a separate space for work or creative activities. The garden is a work in progress, with plans to include a lawn area for the kids to play, lots of native plants, a veggie patch with fruit trees, a small shed, a chicken coop, space for a trampoline, and a small sauna.

Upstairs, the master bedroom boasts stunning views of Mount Dandenong. The main feature of the bedroom is the green built-in wardrobe, providing ample storage space while keeping in line with the sustainability theme of the house. The spacious ensuite features a walk-in shower. There are also two kids size bedrooms, a study nook, and a kids bathroom.

Non-toxic finishes have been used throughout the house, making it a healthy and safe living space for everyone. Overall, the 20/20 Passive House is a beautiful and sustainable home that perfectly balances style and functionality.

The compact footprint of the 20/20 Passive House also means that it has a smaller environmental impact than a larger home. This makes it a great choice for people who want to live more sustainably and reduce their carbon footprint.

You may ask yourself: Why the 20/20 House? What does it mean?

I guess if you have studied architecture and even more so if you design houses for a living, it is only natural that all that you are dreaming of is designing and building your own dream home one day. For us as a couple with 2 architects (no, hold on, I’m not allowed to say that since I’m not registered as one) with 2 that have studied architecture, it was a real mission.

Several years ago, while we were still looking for our first home, that turned out to be our 8.4 Star renovation in Vermont, we started to make plans for our future home. Our goal was to be in our very own home by 2020. Also, especially when coming to Australia, we were really shocked about the quality of the homes and how cold they felt and how difficult it was to feel comfortable in them. The mission was to create the perfect family home. Nice and comfortable, not too big, not too small. Architecturally appealing, energy efficient, sustainable and most importantly affordable.

This was the 20/20 Vision for our Future.


 We did move into our home in mid 2022. But we barely have any decoration yet. So official photos are still a while off…
