The interior of the home was largely left intact aside from the new kitchen and dining and new master suite on first floor extension. The pool was replaced with a neat rectangle pool in the corner of the site.

Is this a new build? I would suggest you look at each room in detail and put the actual furniture arrangement you will have, to the right scale, and think about how you will move through and use those spaces. Some of those look odd to me, but it may be the way you intend to use those spaces is different to my imagination. The access to the changing room seems only through the Kitchen. and either out the front door or dining and living to get to the pool area. How will this be fenced? Where is washing to be carried from the laundry? Is there a line nearby? Out the front door, or through kitchen dining and living? Bed 4 has to go through a living space to a bathroom, the living room is hard to imagine in use as arranged, and bed 2 and 3 look to have the beds right into a corner for no reason. How would you accommodate a double bed in these rooms? In a few years this may be what you want. If you will have other furniture, draw it in. There a large walk in cupboard/robe off a store room. What will be in the storage room? Draw that in too, so you know there is space and it won't block access to the robe. Many of the storage spaces/benches/shelves are shown with corner shelving arrangements which isn't often the best use of space. Bed 1 looks out onto the front access. How will you provide privacy? What different uses do you imagine in the living, family and rumpus rooms?

I can't get the picture to blow up big enough to see much , but unless you are running a backpackers , I would suggest 1 bathroom for 3 bedrooms would be all you need , in fact unless you are having a 'grannie flat' or similar built in , I would think that 2 bathrooms and a 3rd powder room with its own handbasin would be all you really need . Of course , more is more luxurious , so having a second ensuite is good , having a shower and WC in every room has advanatages , mind you so does having another with a bath and twin showers , 3 seperate WC's in case you have 100 people visit , a seperate spa room with its own shower and toilet , a sauna , an outside pool with its own male and female changing rooms with showers -- in other words , do what YOU want once you get past the basics . And I'm not a fan of two doors from 2 bedrooms into a bathroom -- especially if there is a bath or shower and a toilet -- it relies on everyone working together , but also on everyone pushing the right combo of locks so that there's no accidental walking in on someone .

windows in master bedroom need to allow views and privacy and much as i would prefer bed on NE this keeps the bed in view towards and from family room so prefer bed on south wests wall and small sliding doors pushed towards north side of room with tall narrow window beside sliding door and highlight window for light with privacy and wall space for chest of drawers...acknowledging theta the pwdr doesn't have a window but my suggested arrangement uses less total space more efficiently and is better for older kids and long stay visiting parents (more people can use the various options at the same time) and a small ventilating skylight will exhaust and brighten the toilet and vanity area ...the wide door into the lounge can be a stacker or stable door so you need to investigate local options (and everything is expensive unless it does what you want...we always use solid core doors that can be ten times the price of a basic hollow core door but love them so we economise elsewhere) and barn door between entry and family would be OK as long as you like them and it doesn't compromise lounge doors but could look ok if both doors are the same style and different widths...and location of dishwasher is personal and if you have already been unhappy with sink in main kitchen then have it in the scullery...main advantage of my suggested kitchen location is that it's closer to the front and the family area and external doors and the pantry uses the central space that can be much better illuminated with another ventilating skylight instead of a tiny external window and noisy exhaust fan
