Hi "theomoors" It is a great opportunity to live on forty acres just North of Melbourne, I congratulate you on your purchase, I can understand why you are looking for all possible ideas. You have a very "ample plan" with lots of living areas which I'm sure you intend to make great use on long winter days. There might be a way of planning the same areas and make some of the spaces slightly more efficient and still get a good result, and reduce your running costs a little especially heating in winter. You might like to consider placing your furniture on the drawing, this will give you a greater understanding of space and circulation and where you might need to reduce or enlarge to obtain a better result. Also you might like to look at your L shape Plan design, it does not really take advantage of the North orientation and the views, (especially for the rumpus and upstairs areas) its seems a pity considering that you have 40 acres of land and not take full advantage of Orientation. If you could manage to re-look at your design and try a liner design, then your rumpus room and the rest of the living areas would take advantage of both orientation and views. (I think Evirotecture has mentioned this design issue) Also the massing of the whole structure seem to have more of a "large corner suburban block feel" to it, rather than a "a rural feel". You might like to look at something with more balanced proportions, both in plan and elevation might give a greater feeling of restfulness to the design. At the moment the design seem to remind me more to a outer Melbourne northern suburbs rather than rural design. Looking at some of the existing rural houses on any Google search might give you a point of reference. As you have a northern entry with some steps, you might consider developing this a little further to give a welcoming feel, considering that this is how you see your "property on your return home" when you are tired, you want a welcoming feeling. Maybe a detailing the front (elevations and Views) with larger drawings might help in this pursuit, even it you have to use decking materials that are highly fire resistant to meet fire requirements. I like the way you have planned the kitchen, the island bench with a butlers sink and a full sink behind with a full butlers pantry seems to work well. The circulation space around of 1000 is slightly undersized 1200 is generally the preferred space if you can afford it, I make mine never less than 1100. Also you might consider the space between the hot plate and the sink, about "one working station" (about 800 to 1000) and the hot plate the same distance from any wall seems to work better than greater distances.. Closet space for linen, hanging of clothes while ironing, brooms, vacuum cleaners, freezer/s, shopping trolley, and all the other knickknacks that make up a family seems slightly under-catered. Maybe an inventory of existing storage might be a help in coming up with requirements. Also the fixed size space for the fridge can sometimes be a disadvantage as size and function of fridges tend to change, and it might reduce your capacity to upgrade later on, straight line space might be a better solution. The laundry, and that section of the kitchen might need a slight redesign so as to incorporate a more flexible result. It would be a good idea to show the position of Water tanks, hot water heaters, solar cells and storage, wood storage for the fireplace (BAL requirement in some states), air conditioning units & pumps, and all other mechanical equipment. These items relate to the house design and can be highly visual, and sometimes may require specif placements which may influence the placement of windows and doors and can be pleasant or unpleasant when viewed from certain perspective, so taking them into consideration at this time may avoid later issues. Also you have not shown vehicle storage and circulation in relation to the site which may influence the design directly. You might also consider a "Mud Room", I can see a relatively good size deck from the laundry and rumpus room which might help, but if this is not well sheltered people tend to be lazy and bring the mud inside rather that change shoes or clean up as required. A good size mudroom might help to store boots, raincoats and other heavy gear often required for every member of the family, in a small farming environment. You might like to combine this with a "pet area" considering that you might have a dog etc. that forms part of the household. There are other areas that you might like to look at in relation to fire requirements and sizes of glass especially in your first floor areas. It might worth while, if money permits the use of fire-shutters at least in the upper areas. New homes are definitely a grueling exercise, but it is always easier and cheaper to change a design than the building. I hope my comments are of some help, I wish you the best in your en-devour, and look forward in seeing your final design proposal. Regards - Michael Manias .

thanks everyone. oklouise, plans look fantastic! After some serious evaluation and looking how much garden would be left at the back with all the bedrooms downstairs (and wanting to put an 8x4 shed at the back) we are almost concluding that we need to put some stuff upstairs to maximise the block. Initially we thought about just one room but it seems the setup costs to get up there (approx 60k we've been told) make us think we may as well put more up there and maximise the size of the block to allow us to have a garden and veggie patches, trees, chicken coop etc. I was concerned if we gave the kids their own space upstairs we would never see them, but I think in reality putting the second living area upstairs with 2 bed and a bathroom is probably going to extend the life of the house and appeal to more if we do well it later.. . I also read a few chapters of a book from the 1970s architect talking about the optimum design for small families suggesting that there should be 3 non bedroom areas; one for children, one for adults (to not be parents) and a common area for both, which resonated with me - can't recall the name of the book. We spoke with a engineer 're the excavation for garage and they estimated 60k, and I think I'd prefer to build up in that case. not sure if I would bother with a balcony though as it would push us to to 3 outdoor areas, but may really improve the facade with a balcony... listened to those podcasts from the undercover architect - absolutely fantastic. so much food for thought. Now realise how lucky we are to have the view north.

Shifting the laundry will create a larger laundry and allow for a 'kids bedroom zone' with better access to bathroom for all 3 minor bedrooms. Place the rumpus where dinning is. This can be separated or use the great sliding wall/door idea. It also allows view from kitchen. I agree with moving the fridge and creating a more open WIP. This also allows for a WI Linen - which could be opened up to the mud room, or even a powder room. I found the front living room to be an awkward size and shape so did a slight rearrange in that area. This gives the Living Room access to the north facing patio/outdoor area, tying all the living spaces together while keeping them seperate.

Thank you. The level of insulation provided by ICF construction depends on the type of ICF system is used and the thickness of insulation, but it is often greater than R3. In Australia the insulation levels achieved in ICF construction is in the range of R3 to R6 . We used the 203mm foam blocks that gives an overall width of around 225mm.
