Sorry to continue....the plan by Louise on the 20/01/2017.... But the laundry ( with internal access or through cloak room) and ensuite to the rear of the garage the master behind...... Then a Wir separating the master form the living or a bathroom...... The a fireplace if required against the western wall central in the house.... The entrance and small cloak room for the winter woollies against the garage and the other three beds at the front RHS with bath near.... The lounge/ kitchen/ dining in a similar layout but with minimal a walls blocking the view from the entry to the living/kitchen .... I like at lease a small wall dividing the living and lounge for the teenagers also.... If I get an chance I will sketch something up. Good luck this the paperwork... Plans are the fun part.

I would be looking carefully at your bathroom and powder room arrangements, especially with the shower and water splash distances. I can't see any shower screens to either shower? As it is drawn I hope you like mopping floors after every shower. For a family home there will be privacy issues when someone needs to access the laundry, while another family member is having a shower. I would separate the laundry and family bathroom into two distinct rooms as the current design is a compromise. With space so tight the second shower in the powder room seems excessive, and it is so small it is not very functional. You need to think carefully about the freestanding bath, the space it takes up, and the cleaning around it. A more traditional bath hob will give you fewer compromises in other areas as it will take up less space. Have you considered flyscreening with your bi-fold doors to the rear? Have you considered how you are going to furnish the living room? There is lots more, no doubt other Houzzers will pick up on. If you want a proper, detailed design/review or chat feel free to contact me. Best of luck, Dr Retro of Dr Retro House Calls

i have a problem with the awkward location of stairs that wastes the sunroom, makes the rumpus room difficult to furnish and the front door has a view of the toilet ...beginning with central stairs and potentially modifying doorways to allow for the stairs without having to walk across the rumpus or upstairs living room attempts to avoid the big wide hallways affect without useful locations for furniture ..the rumpus room now has space for comfortable furnishing and private access to a full bathroom and good sized laundry...using the old sunroom for a compartmented bathroom retains the original walls and windows and includes space for a bathtub and shower with big views.. we should always include real scale sized furniture to establish the best walking paths across rooms and my suggestions also retain the size of the original kitchen to keep more of the original walls and ceilings and retains the proportion of the bay window and allows space for an alternate access to bed 3 (preferable the linen cupboard would remain in this location) and consider avoiding the enclosed pantry (would the door ever be closed?) in favour of a more open space for better light and ventilation and maybe a herb garden window box in the bay window with external blinds to exclude western sun.. there's a fridge closer to the outdoors, stacked wo and MW to define the pantry and only a small sink in the island for more useful set down space for shopping and serving meals

From a "passive solar design" point of view, everything is right. Rectangular home facing north/south. With north facing living rooms, rarely used rooms to the west. But one other thing to consider, plumbing. Locating it close together will lower building costs, & the wastage of water, waiting for hot water. So I'd consider swapping bedroom 4 for the western wet areas. Behind the kitchen is have the laundry, then bathroom, then linen, the bedroom furthest to the west. I'm not mad about western bedrooms, especially in hot climates. But in this case it sounds like it would be used sparingly. Plus if make sure there was no western window, just a northern one. Insulating the western wall well, & using a radiant barrier (reflective insulation). The approach will also significantly shorten the length of the western hallway. Greatly increasing the size of bedroom 4. Talking room sizes, & room numbers, from a sustainability point of view, I think the home is too large for what is likely to be a two person home for much of the time. The embodied energy (emissions created) from a new build home is huge, averaging 15 years of operational energy. I'd be looking to reduce the house size, by using multipurpose rooms. The occasional kids housed in the study, or the media room. This can work out great with clever design (like incorporating murphy beds). How will the media room be used? Will noise be an issue. Will you be happy to have it so close to the master bed? The building orientation/shape will be great for solar PV, with a large roof area facing north. I'd I was building nowadays, is be aiming for an all-electric home. Ditching gas - of its even available where you are - in favour of efficient electric appliances. Reverse cycle AC for heating (if it's required), supplemented by fans for cooling, hot water heat pump (extremely efficient), induction cooktop (sensitive, fast acting, easy to clean). All powered by solar PV. If it's an option, I'd look at 3 phase power, which will let you install a larger PV system. It will also allow you install a fast charger for EV, likely to be your next car purchase, or soon after.
