All buildings have been designed to maximise comfort by using passive solar energy, cross ventilation, thermal and acoustic insulation, wood heaters and fans.  Construction materials have been chosen to compliment the surrounds as well as for their practical application.  The use of strong chemicals for termite protection has been avoided where possible by using cypress timbers, termite mesh and practical design.  Unfortunately it was necessary to clear heavily wooded areas to position buildings safely here at Heaven, but all timber has been used onsite for landscaping, fencing, rough construction, or future firewood.  Reforestation of these areas has been a priority.
