Hi there - a few things stand out to me... yes keep bedroom sizes no less than 3000mm wide, offset the door to the laundry so you can't see the toilet from the front door - yuk! Minimise/simplify number of piers by turning front porch 90º. Keep the footprint as simple as possible. With oklouise's plan, which i think makes more sense, cut 300mm into each of the bedrooms and push out towards the left into the deck. Much better use of space. If west is to the left put a whole wall of cupboards along in bed 1 and get rid of the others, and add door out to deck on the (new) north wall. Do you really need a bath? Living in country they are wasteful of water even if it goes back onto your land. Alternatively have a combined shower/bath? Babies and toddlers wash quite well in the laundry tub then learn to shower with you or on their own quite happily. I'd make the shower a big bigger (and the cupboard on the hall side) and get rid of the bath. Make sure you have excellent insulation in walls, ceiling and under floor. Consider hebel panels as flooring (also, the reinforced ones span great distances) and walls for both fire safety and insulation value. If possible look for ramp potential in case of disability and also for getting furniture into house. If you're in a fire zone make sure all windows and doors comply with your zone rating. And if you are building high up on piers make the external cladding is something that never needs painting and is minimal maintenance.

I'm going to thro a wobbly into this mix: Have you thought about going two storey so there is some outside space for boys to play? Looking at your site plan play is either in the pool or the street! Master bedroom, with all the robe you want upstairs and a kids free zone! Or boys rooms above as long has they do not own hob nail boots! Then do not use ALL the extra space on ground for your film works! Seriously this would give you some breathing space and some real outdoor living area to enjoy which you can do in Ipswich climate. Four beds separate bath rooms and stairs above with a laundry chute. Down stairs a real laundry (proportional to a five bed house) A powder room with shower for after pool. Your study of a size worthwhile and theatre room for family second sitting room as well as clients. The master can then have better sized robe, all the bits you want in ensuite including separate loo (lovely idea) but please on outside wall with window. Personally, I'm not one for two storey but in this tight site I think it would be much better. Good Luck, Margot

I really love the work of Ross Chapin, he has really influenced my approach to homes in general! He is a US (i think) based architect who champions small homes and has a concept called a pocket home. I've read a lot of his articles and he likes homes that are homey and cottagey and small neighbourhoods with common parklands and great greenspace access. One feature of his homes is they are typically 1-2 bedroom a thing he often does is replace what would in other homes a whole room with a nook. So for example, a hallway might be extra wide but have a nook for an office that could be closed off with a sliding door into a spare room. Or an attic space that can sleep grandkids, dining nooks off the kitchen so entertaining is possible, like an oversized bay window. Decent living spaces. His designs are worth a look at to get some ideas. https://rosschapin.com/plans/small-houses/ I've also stayed at a newly built unit for an elderly person. There was this large foyer space at the entrance with an extra wide door that was level with the paving, no lip at the entrance. It was designed so ambulance access would be easy in an emergency. The large foyer had cupboards with a laundry and storage, and then there was a bathroom directly across, again for easy emergency access. There was a phone in the bathroom too in case of falls. The whole area was tiled from door to bathroom for easy maintenance and access. The kitchen was simply run across one wall of an open plan dining and lounge area with like a corridor of tiling to designate it as separate. You can use flooring changes to create different spaces. It there were no awkward pokey spaces and it was the easiest place I have ever stayed for cleaning and organising. There is a universal access guideline, its worth checking things like bench heights etc... https://www.architecture.com.au/wp-content/uploads/Universal-Access-Policy.pdf

my previous post was to illustrate how much space there is around your house for a generous 4 bed 2 bath 2 living area plans (i used my own house plans to avoid breaching any copywright) but here is so much land left over that i can't fit the imnage into a readable post and i've had a look at your new plan and it looks good for your wish list but do you want 4 bedrooms and drive through access to the backyard or space for a pool and/or a pool house or separate workshop or mancave and, before considering this plan you need to check with local council if they will approve the garage at the front of the block...usually councils prefer that the garage is further back than the entry but itm i will consider some ideas for you
