Parker Cottage Guesthouse is striving to combine luxurious hospitality with an active project around sustainability and the environment. Parker cottage would like to show that it is possible to respect the earth while running a bed and breakfast and by 2015, Parker aims to be 'off-grid' for water heating, electricity, water and sewage and recycling 90% of their waste.
 
Phase 1
Completion July 2010.
Install loft insulation to lessen heat absorption in summer and retain heat in winter Replace first electrical element hot water cylinder with a solar-ready one. Install ceiling paddle fans instead of air conditioning as necessary Plant only indigenous or water light plants in the garden of No. 1 Carstens Remove alien vegetation (yuka trees etc.) from garden Recycle 80% or more of household solid waste at local recycling site.
 
Phase 2
Completion July 2011
Install a roof shade/terrace on the flat roof sections to minimize the heat absorbed by the first floor roofs Cost the installation of a biodigester and French drain and connecting all sewage to it. Cost the installation of an on site water treatment plant Cost a centralized heat exchanger system to add additional cooling and heating capacity Install 1 x 5000 litre capacity water butts to catch winter rain from the roof Install first photovoltaic panel and deep cycle batteries in roof. Run at least one fridge off PV panel energy Install first solar water heating panel Replace all light bulbs with warm white energy efficient bulbs. Replace lower level steel roofs with heat and glare resistant material.
 
Phase 3
Completion July 2012
Install biodigester for sewage and biodegradable waste. Install further 5000 – 10 000 litre capacity water tank below veranda Install second and third solar water heating panel Install further photovoltaic panels and deep cycle batteries in roof. Run all computers, fridges and lights for at least one house off PV panels Connect hot water cylinder to urn in kitchen for ready boiled water.
 
Phase 4
All hot water cylinders solar heated
80 – 100 % of all water treated on site
80 -100 % of solid waste, organic and inorganic, recycled
80 – 100 % of all electricity solar generated
House heated and cooled by heat exchangers
