Just trying to study your floor plans which unfortunately I can't read so can only guess at the room use. I have no idea of the room sizes either, but I'm just wondering if you have actually done furniture layouts for each room to scale. This is really important. It seems to me like you have some great ideas you have picked up but then tried to make the rest of the house fit around them. How many people do you intend having live in the house? You have a lovely generous ensuite with a private toilet area for two people, but then have a main bathroom for how many people, jammed into a space almost half the size of the ensuite. Even the toilet is in there with no privacy whatsoever meaning that entire space can only be used by one person at a time. If you are planning this for kids, that will translate into lots of fights and arguments. If you want to create a really luxe and practical space, create a separate enclosed toilet, the shower and bath in an enclosed space and the vanity open for use at any time. This would be more in keeping with the standard you have set in the ensuite and balance the house so much better. These sort of details have a major impact on the overall value and attractiveness of your home. I don't know what you plan for the open space upstairs, but with a window along one wall a passageway the other side and only minimal wall space your use of this room will be severely restricted. Similarly the room under it will be very limited in its use. All the more reason to plan furniture to scale. I have seen master bedrooms done with the double doors which look very grand in the right sized room but in the wrong sized room, it just looks ridiculously pretentious to fling the doors open with a flourish, take two steps into the room and fall over the end of the bed. I'm sorry if I'm sounding harsh here, just trying to use my years of experience to help you create an amazing house. I've seen many pitfalls and I know how easy they are to make. You obviously intend spending a lot of money and you have some great ideas judging by your Ideas Books. Create more Ideas Books to cover every room of your house, then go talk to an architect, show him/her what you want, your Ideas Books will be invaluable to understand your likes and tastes and let him/her create something unique and special for you.

People love to kick up a fuss about everything and anything!! If you would like to have the bathrooms upstairs using a different tile to whats downstairs, then do so - as long as there is consistency whether it be in colours, size or shape of the tiles. Seeing as it's going to be from your living room, I'm assuming it will be a non domineering coloured tile, which means that even if it is in the bathrooms and laundry, you could always have an interesting wall tile or colour to bring some individuality into those rooms. I don't think it's a cardinal rule, but from an interiors point of view, too many clashing designs, styles, tiles, colours etc can cause a headache. Also resell - when that time comes, it really affects the valuation as future buyers consider that an on-top expense after purchase.

Could you extend the study nook out to the left to create a meals area (combination of built in bench seating and free seats) and then depending on which room you wanted seperate to the kitchen/meals allocate a lounge and playroom to the now semi divided rooms? The kitchen configuration looks like it should stay, assuming you’re not extending out, but you could enhance the two rear windows to take in the yard...

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
