Hey Nik Star, I've had a PowerPoint play with oklouise's edits. This is what I meant about garage entry to the pantry and a laundry in the garage. The red arrows are to stipulate to the builder that level access is required. I added extra garage depth to allow for the garage, that would definitely impact your facade elevation. If you remove the wall between the butler's pantry and mudroom you would have a SUPER PANTRY! But a true butler's pantry in that it was supposed to be where you would land with the veg from the garden so you would kick your shoes off inside the door, so I've noted a little bench seat there, then head in and wash it before heading over to the actual cooking area. Then if you get rid of the sliders and reduce the storage to shallow shelving on the middle wall you would have plenty of space to manoeuvre with mobility devices. For the washing labour machines - washer, dryer, dishy - try getting those mounted on plinths so the load on your poor back is reduced. I have dodgy joints so I am researching all the ergonomic ways to design work spaces to help me when I get to the awesome stage you guys are at with getting to build!

@oklouise - that's ok, I've managed to redraw and tweak it a little as well! I think for us, we will actually not use the formal living as a formal living, but as an Office/Library. We work from home quite a lot, so we would need to look out at something, preferably a nice garden or the backyard. At the moment it will be looking out onto the side with 2-3m's of gardens, so that will be very nice :) We can create a nice courtyard area for where the formal living/study windows will look out to. The area that is marked as a study in your plan, maybe is not needed or used to create a larger ensuite and WIR. I quite like the rectangular kids zone, I can't see it fitting two sets of seating, but I can see one half of it having a drop zone where bags/jackets etc can be dumped as they enter the house. At the moment in our current house (which will be knocked down to build this), we don't have a dining space, but we have a huge deck which we entertain on a lot in summer, but in winter, we cannot entertain at all :( That is our biggest gripe! I am wondering if this problem can be solved with having a deck that can be closed off with stacker/bi-fold doors, because to be honest, if we can entertain outside in winter, we would much rather sit outside looking at the gardens then be inside! :) That also means we can shrink the footprint of the house, and thus have a larger backyard. @Paul - We actually did want a side entrance, but I couldn't think of how to work that in .... Wrap around porch would be amazing! @Ruth - The rooms will not be looking out onto a 20cm blank wall :) They will be looking out to 1m gap, thus will have a side garden. Ideally everyone is sitting together in the living zones together and not in their rooms :) Porch hardly counts as a living space! The formal living will double as an office/study, so I don't think that will count as a "living" space. Three living spaces does seem excessive, but there will be three generations of family in the household! I think as the family grows, we need to allow space for kids play areas to evolve to craft areas to evolve into studying areas then to relaxing areas as they start working. Also want some of these living areas to double up as guest sleeping areas for sleep overs and friends coming over :) Would love an internal courtyard for the master! Originally we were trying to get the master to have a view into the backyard with doors that go out to the backyard! I think taking into account what I've said earlier, I will try and do that by removing the formal dining area which we don't really need! I also wanted to have a rooftop garage, but I think that's probably too ambitious taking into account our budget. Everyone's comments have been great! Has given me lots of ideas of what can be changed/updated to improve the floor plan :) :)

underfloor heating can be installed under some new floating floors and fitted carpets but you'd need to contact the manufacturers of the flooring and heaters to confirm precise conditions to suit your existing timber floor but we have an electric blanket style floor heater that slips underneath an area rug and is excellent for keeping feet warm under a table or desk and just plugs into a wall outlet ...we're very happy with our Coldbuster heaters that can be ordered on line in various sizes but first try some large area rugs for instant insulation that can be removed in hot weather

Ps. My island in my current small kitchen is on lockable castors. It was made by the cabinet maker at the same time as the kitchen. On three sides the panels go to the floor and you can’t tell it moves. The front with drawers has no kick board so you have access to the castors. I don’t move it a lot but it was handy when the kids were little - I moved it totally out of the kitchen and put in a small table. Occasionally I move it over a bit if both kids are cooking at once.
