We bought our new home at 16 Livingstone Street in April 2013. The 1970’s Italianate house sits on a quarter acre surrounded by subdivided blocks – instead of bulldozing the house to build two big houses, we wanted to try something different.
Warden (ocean) is a single room studio apartment. Moveable book cases and wardrobes mean the space is flexible. A special bed with plastic storage tubs on wheels underneath, plus a well-designed kitchen located in the previous hallway mean the 37m² space works well.
Ngardak (underneath) has been created by dividing the triple garage space into a one bedroom apartment. Moveable soundproof walls separate the living space from Tim’s workshop next door, and this plus the installation of a commercial kitchen allows for the possibility of using the space as a classroom in the future. A funky semicircular shaped bathroom dug into the limestone caprock is a feature of this 45m² apartment.
Koolark (home) is our place, and consists of an 18m² bedroom and clothes storage area, a small bathroom and a 51m² office, kitchen, dining and living space. Koolark is in the middle of the house but the clever removal of roof space and the installation of a solar pergola allows northern light to penetrate onto the concrete slab in winter.
Moortung (extended family) is the common shared area of the house, consisting of the front verandah, side kitchen and dining area (66m²), small storage area and laundry (with shower and loo). A full height loft provides a space for airbnb guests, WWOOFers and other short term visitors. This space faces north with 6m² of sliding doors and a large pergola there is good northern light and heat control.
Ecoburbia continues to run it’s famous monthly movies over summer, but we now have a purpose built outdoor movie area created from the tiered front garden.
Our two goats (Whimsy and Little White) share their pen with 12 chickens, and provide us with enough milk for our needs, the making of goat’s cheese and some trading of milk. Two other “non residential WOOFERs” trade milking skills for goat’s milk.
The rainwater system proved to be a major project. We installed a 50,000 litre concrete rainwater tank underground at the front of the block (no mean feat when the heavy machinery had to dig into caprock).
Tim estimates that with five people living here, with a daily water use of 50 litres, we should be able to survive 100 days with no rain, essentially taking us “off the grid” in a typical summer.
Two evaporative tube hot water systems serve the needs of the main house and boodjar, without the need for back up heating.
The living spaces with northern aspect should not need heating, but south facing warden and ngardak have both had wood fired pellet heaters installed. Low tech power saving initiatives include solar ovens, cookers and food driers available for residents’ use. There are no televisions and one computer modem services all residents. In the future a battery bank will ensure the house is “off grid”. We are also looking at miro steam generation.
But that is not the only reason for having rental accommodation on our property – we are realistic about our financial sustainability as well. We hope that once Ecoburbia is fully established the income from renting the various accommodations, coupled with our reducing living costs, will enable us to spend less time worrying about income and more time doing the sustainability work we love doing in our community. We are looking forward to being able to more fully integrate our home and “work”. We like the idea of retirement being the freedom to do whatever work we like without having to worry about the money involved. We want to be able to age in place.
Ecoburbia is run by benevolent dictatorship – even if there is sometimes disagreement who that is! Visit ecoburbia.com.au for more.
