Yes please, we have a retaining wall dilemma & have bought 2 round tanks but yours are ace! I saw you website a while back & put it in the too hard basket case, lol! Message on my profile works fine thanks David, cheers LouieT

@HU-319610855 I’m not saying this to be even the slightest bit contradictory, so please don’t take it that way. We had seperate everything. Doors, walls and divisions everywhere. We pulled it all out and went combo. We‘ve never had an issue with conflicting use, and we love the feeling of extra space and openness it created. I’m sure it all depends on your household. :-)

also in NSW we were given permission to build a habitable room over sewer pipes as long as the the sewer pipes were encased in concrete according to Council specs and we couldn't use a concrete slab floor and had to build the room on piers with an accessible crawl space underneath the floor..we took all our info to the local building inspector and they suggested an ideal work around (by moving our building sideways) ..but i'm shocked that your building designer allowed the planning to progress this far without identifying the potential problem ..could you move the studio closer to the house with a courtyard space between dining and studio or build a proper non habitable room ie out of different materials eg a sound insulated steel shed build on piers..there must be an answer and your building designer needs to do the research as they should have already known..best of luck

Firstly OP, I believe the NSW government has no rebates for solar (except a minor trial for a low income rebate for solar in selected areas). Only a loan scheme. The main rebate for solar is the STC rebate, which is a federal rebate. Victoria has a state rebate, worth an additional $1,800 (plus another $1,800 as an interest-free loan), or there abouts. But to the crux of your question. If people have an unshaded roof, I think they'd be crazy not to invest in solar PV. Technology has improved over the years, & prices have tumbled. In most areas, single phase homes can have a solar system up to 6.66kW (5kW inverter) installed - any larger than this & export limiting will occur. A system this size can be installed for somewhere around a cost of $5,000 - $6,000. $3,500 to $4,500 in Victoria. With savings on electricity of up to $1,500 a year, payback times average from 3 to 5 years. After that is all profit. Tell we where you can find an investment with these sorts of returns. From you bank, shares, real-estate, I don't think so! If I was building now, not only would I spend a lot of time getting the passive solar design right, & making sure my building envelope was well insulated & air tight (most new Aussie homes are very leaky). I'd also make sure my roof was well designed to accommodate solar panels. This is often not the case in Australia, where we have a fascination for hip & valley tilled roofs. Hint: a rectangular panel doesn't fit well on a triangular roof face. A complex roof, with multiple angular roof faces, over many aspects, will reduce the available area for solar panels. It will complicate the installation, increasing costs. Plus the final result will look like a dog's breakfast. But I'd be going much further than just installing solar panels. I'd be building an all-electric house. Split system reverse cycle AC (heat pump), the most energy efficient, cost effective form of heating. Fans for cooling (AC is energy hungry for cooling). Heat pump hot water, again, the most energy efficient way to heat water - unless you're in northern Australia, where solar thermal water is a good option also. Induction cooking. As responsive as gas. But with even more control over temperature, & far, far easier to clean. This means no gas to the home! A saving of over $300 a year, just in service charges alone! Plus cheaper running costs, especially when powered by solar PV. Installing solar PV & saying no to gas is also far better for the environment. The federal government may tell you that gas is a great transitional fuel, it's not! Why was the CO-VID Commission stacked with gas executives? Jobs for the boys, their fingers in the pie. Not only does combustion of gas create quite a lot of carbon dioxide (about 50% as much as coal). But natural gas (methane) has a global warming potential of 25. That is, it's 25 times worse than carbon dioxide! This means that if only 3% of it leaks into the atmosphere during its extraction, processing or transportation, emissions are just as bad for gas as they are for coal! Progressive government's like the ACT are considering banning natural gas from new developments. Other government's, who are too friendly with the fossil fuel industry, & are addicted to their political donations turn a blind eye to science & tell you gas is great!
