Is it expensive to incorporate environmental features into my new home?

No!
The initial investment in incorporating a full range of environmental features in an Ecovision home including building in Urbanform, using E rated glass, full insulation to roof and ceilings, installation of power saving lighting and appliances,  grey water installation, rain water harvesting and water tanks, drip irrigation systems, water saving fixtures and fittings, photovoltaic power generation and solar hot water systems would be less than 10% of the cost of construction but have immeasurable future cost saving benefits. With our buying power these costs are constantly reducing as a fraction of overall construction cost.
