100 Hubble, an environmentally friendly accommodation, boasts the following eco-friendly modifications:

Recycled building materials - Andrew is a self-confessed 'hard-core appropriator': all materials, from the structures to the tiles, are remodeled 'found objects'. Some of these objects include a cray fishing boat wheel house (now a kitchen), a 1950's phone box (now a shower), and a timber railway carriage (now the master bedroom).

Organic Matter - All organic matter is composted with the aid of worm farms, and placed on the garden.

Grey Water - With respect to conserving WA's water, all "grey water" (shower, kitchen, sink & laundry water) is used to water the gardens and lawn. The grey water is distributed by an underground filtration system, rather than being spread over the surface, so there is no smell or residue.

Cleaning Agents - Only environmentally friendly detergents and cleaners are used.

Northern Lighting - Lighting is based on the "Northern Lighting" concept. This means that all structures have been built to accommodate natural lighting, allowing for warmth in winter and coolness in summer.

Solar Water Heating - All the hot water supplied in the accommodation (showers, laundry, kitchen etc) is heated by a modern solar hot water system with a gas booster.

Alternative Power - The one area that Andrew is currently working on is an alternative power source. The current options are solar power or wind power or both.
