We're already at the "old age" with problems stage, so have gradually adapted most areas to suit our limitations. What has amazed me is how suddenly the body changes have seemed to come all at once. We have a 4x2 on a quarter acre close to amenities, and I would hate not to have it. I love having all our varied fruit trees and raised garden beds, but admit I have a strong young man to help for 2 hours a week. Had spinal and knee ops last year which has limited what I can do. Bad part of getting old is the mind staying young - tells the body to do something beyond it's present state. Example is lifting a huge bag of fertiliser out of car boot. Result was spinal surgery, and being told that lifting heavy objects will put me back under the knife. The 1 thing left to do in the bathrooms is install higher toilets, as the knees don't bend so well any more. Walk in showers, bidet toilet seats, and heated bathrooms are a boon, and grab rails are well used. We have a small step to the patio, but have installed a ramp for that, otherwise we have no other steps. Rugs and carpet have been replaced with tile which is easier for using walking frame. Installed more and brighter lights for OH,s fading eyesight, and replaced our t.v. with a larger one. Have enclosed part of our huge patio to create a sunroom off the family room. This brings more warmth into it when the sliding doors are open, and we can vent the heat in the hotter summer months. Our next project is to replace our [only] 4 years old kitchen so we don't have to bend or stretch so much to reach what we need, especially all my appliances and gadgets. Now all we have to do is hope we live long enough to enjoy it lol !

Hi there Nick, looking at your photos you look like a modern hamptons family which is lovely, do you live in a warm climate. I did like the photo you posted of the open plan living and think that you are on the right track with interior colours I have marked out how I would like the first floor, I have moved the kitchen to the end wall to line up with BBQ outdoor kitchen, plumbing for this would have easy access via the garage below. The white tiles look lovely and hard wearing for the entrance foyer and Rumpus room, the stairs in timber due to the amount of traffic even continuing in up stairs foyer kitchen dining living, Carpet in bedrooms and downstairs theater. Kitchen in white but possibly Shaker style white doors these are very popular. Using existing sliding exterior doors if possible from kitchen.Dining to verandah, I think this ceiling would be best kept white to help reflect light back indoors, the tiles appear to be in good order but you might consider changing these along with new upstairs flooring Some where for a laundry shute would be handy, actually a Dumb Waiter so you could move the laundry with ease both up and down! The roof painted a soft colour, grey/white or off white, the verandah railing could be the same colour or you could do glass. The builder had a very different style of house to what I think you are wanting. Your photo

If you "change" anything that involves a building approval then the floor area on the plans relevant will count towards the overall amount. If it amounts to beyond 50% of the existing conditions then the whole building becomes applicable to energy calculations and so you enter into up spec'ing existing areas. And yes it can often be a good thing to be doing anyway, but of course it costs money. If the total area being changes is below 50% then only the areas of new work are applicable. I'm honestly not a specialist in this area, but I have to deal with the issues naturally in the course of the design and resolution of project solutions I provide, and hence I use an energy consultant regularly and we have a way/system of working through together how best to achieve the requirements for permit. As far as I understand it's a case by case/project specific exercise and also there's various ways of negotiating/achieving the necessary performance requirements - e.g. you can play around with different levels of insulation together with a particular glazing/window spec, and depending upon circumstances you can save money one way or another. Sometimes I'll squeeze windows overall down to get it under a certain amount to not trigger requirement for expensive glass...also timber windows rate better, but if you are in a bushfire area you'll be caught out or require very expensive timber windows...it's a real juggling act in particular contexts...which is why you really need to be working collaboratively with an energy consultant/specialist to work out the best solution in this regard, as well as the other aspects of design, structure and bushfire etc. It's a true team effort ;) If you're really up for some technical reading you there is some further energy info here NCC Volume One Energy Efficiency Provisions 2016 - Australian ... but it may get confusing........Coming back to the core of it, my advice: 1. define your budget 2. list and prioritise your requirements 3. seek some preliminary advice/assistance from a seasoned designer doing this type of work to test whether or not the general concept of what your endeavouring to achieve is viable, and this depends upon the relevant context/existing conditions etc (and bushfire rating is yet another layer on top of all this), and then refine the concept from there. If you are just doing a bathroom or kitchen isolated then you can arguably do it yourself, but if you're re-jigging the whole house like it appears you are heading towards, and on a very tight budget then I'd highly recommend (to save yourself headaches and frustration going around in never-ending circles) to invest some of your available budget into front-end design, to get to a solution that works to your nominated priorities so you achieve a viable and professionally advised outcome. Trust me it will be money well spent. Have a great Christmas, and best of luck with continuing to work through it all :)

siriuskey, Yes, the courtyard is open to the sky (no roof over it), I assume this is what you mean by double story. Ref. below photos, I would love to get this look, especially the first and last photo, where you can see family living space from the first floor. I can't achieve this in my plan as it eats a lot of floor space upstairs. The referred plan (photos) has a very big void combining staircase, hallway and dining area. I know it is not easy with cooling and heating when you have such a big void. So, I explored a few ideas (with my limited knowledge on this topic) before achieving the current floorplan. I have also thought about, in my current plan, extending the void on the staircase to the dining area (it is more like L shape) but i wasn't sure if that makes any difference. keen to hear your thoughts.
