House Notes – The Bunker
The Bunker was extended and renovated with a young growing family in mind. The owners were very conscious of sustainability and wanted a healthy, low impact, energy efficient home. By extending and renovating rather than a pull down and rebuild the home owners were able to cut costs along with minimising their landfill contribution and staying in the location they love. Timber, bricks and aggregate was reused, retro bathroom fittings were sold, plants were mulched, excess bricks, timber and plants were given away.
The original house was facing west so the rammed earth extension comprising of bedrooms was situated to the west and the living room and kitchen to the north east. The front of the house has high windows so from inside you can only see the trees.
All internal and external walls are insulated and all appliances energy efficient. The home has minimal need for heating/cooling as the passive solar orientation eliminates much of this. The west and south facing windows have “eyebrows” or awnings to assist with shade in the heat of the day. The solar power is on grid but battery ready so in the near future the family can go off grid. The home is on one level with a wide hallway so it is suitable for multi-generational living in future. The garden is a work in progress and eventually the rear garden will be an organic edible garden with chickens.
The Bunker was designed and built by Earth House Australia
