Your local stone supply should know. can work backwards from the central Victorian granite quarries to ask them who they supply on your side of the city. Many quarries in the yellow pages

Thanks for the photos, they help clarify your situation. A few points. The front wall, going by the brickwork, is approx. 700mm high. You could get this down to 600mm by sloping the lawn or garden slightly. Doing this should be fine and then you can pass the construction off as complying and replacement of existing wall. I'd assume the garden in front is part of the council nature strip in which case you can't move forward. I can't see neighbouring front fencelines so it's not obvious. Often there is up to 600mm between the boundary and the footpath but not always. I think there would be too much gabion. Contact a landscaper for a comparative price with sandstone. Obviously it's cheaper if you were intending to build the gabion yourself. The driveway is quite narrow. Widen it towards the lawn, not the boundary. You need to leave that narrow garden for softening of the fence in particular. A picket fence along the front should look fine in white, if that colour appears on your house but the paling fence should not be white. If you are doing a major reno of the house then the landscape items would be best left until the major work is complete. Then you can consider the landscaping in relation to the new look of the house.

Well it's is simple, as we will now have concrete floor that get huge amount of winter sunlight in that main living room area our thermal mass figure went up. with the use of phase change material in the roof it to give a thermal mass effect but lot less weight. What it does is stores the energy/heat and transfers it back into room a night. You must realise that this is a very exposed site and we had to get min 6 star rating. Our insulation goes like this from roof down 1, R7 Rock wool batts 2. 90mm Phase change Material 3. to support pcm you have to use 12mm ply sheeting in place of plasterboard 4. Float concrete 5. Electric in slab heating 6. Precast tilt, but played down slabs Underslab 7. R7 Rock wool again 8. 75mm foam batts 9. Reflective foil 10. Box in around steel and make air tight as possible Also all the glass is double glazed, argon filled and thermal shield. We had all that minus pcm and failed because standard way of accessing doesn't have it in calulations. i had to go and show council a sample of the stuff an how it works. This is not cheap but we can just about say that room will sit at a constant 21 to 24 degrees all year around without need for air conditioning . Phase change article

You can buy spiral rods specifically made for constructing gabion baskets from weldmesh. Gabions need to withstand tonnes of weight. A few C rings isn't going to cut it as the weldmesh will bend outwards under the weight. Hence the spiral ties which are sold. I looked into making my own gabions but discovered that I wouldn't save any money doing so and would only waste my time and put myself through a lot of effort when I could have just purchased flat packed baskets anyway.
