Well if your over designing and putting in more then what is required you are just becoming a part of the problem. Because the amount of energy that has gone into manufacturing your home and each material in it. Those materials require energy to produce them..... On the other hand yes there is that question what if there is not enough can we trust government policy. I think our focus should really be how can we design homes that design for current conditions, have a zero and no carbon footprint and the costs of manufacturing do not offset this goal. So I do place my trust in the science and research from the CSIRO. And policy that has been created as a result of their research yes.

After I had finished my Archi Masters I was working for an architecture firm who also did a small amount of work for a volume builder. They were actually a pretty good quality builder and at least got the orientation of their 'pre-designed' plans correct. We had the ability to make minor changes to every job and it pained me to see so many simple to implement passive options not being incorporated. Had most of their clients known that they would be saving MONEY over the longterm by making a few minor changes to suit their site, they all would have done it. The problem is unless someone can sell this idea to them as a financial/lifestyle choice, many just think it is about saving the world. It is a no-brainer if you have in interest in it, but for those who don't know, there is no-one there selling it to them, especially on the lower end of the market.

I personally think that it is overkill to get an architect because you think that the orientation of your home is difficult. Its not. You could be wasting money getting advice that is not required. My own home has the heart of the house - the kitchen, facing north. This is ideal because we spend a lot of time here and it is great in winter with slow cooked food in the oven, using the oven to warm the room while also getting any winter sun that is available. My best advice to anyone is to have a home with doors in it; open plan is fine for people with money who can pay for double/triple glazed windows, insulated walls etc and elaborate air conditioning systems. Most people need to think about how they can get the best out of the money that they have available and being able to close doors to keep rooms cool or warm is to me, essential to the fuel economy of the home. So your orientation to me is what is often recommended - it certainly isn't east west. Just use trees correctly to help insulate your home even further.

Hi oklouise, Below is an image of how the houses should fit together. I have included rough measurements for sons house.

I will put measurements for my pantry and vac on tomorrow morning. This image might look slightly different to his latest plan which I uploaded earlier he has altered a few things overall still same footprint. I'm pretty new to anything to do with designing house plans so thanks for all of the suggestions and plans so far. I definitely like the way you have narrow shelves for storage in your pantry. but
