cheaper and cheaper (1879 days ago)
It looks like I’m starting to get the hang of this: after the (n)teenth design model over the past year or so, I seem to have found myself (surprise-surprise) with a conglomerate of all the previous designs, all rolled into something that promises to be very affordable (and flexible)

A quick study showing the 45° council-stipulated shadow-setback plane (the primary constraint on this site I've found), some notional portal-frames, the inclined slab anchored to the slope, and finally the concrete wall/blades on the northern edge (to help trap and store as much of the sun's heat as possible). This technique can be used anywhere on the site, and still use the same set of standard components AND remain within council planning guidelines.
Been trying to reach you in past few days..no luck. Could you send me your contact info?
I may be coming to Australia next month. It would be great to see you.
