Where is north. If it is not at front I would have the guest room at front and sitting overlooking pool

The plans are hard to read so at the very least could you maybe post larger ones, and do you have elevations? I'm not sure what you mean by "aesthetically" but I hope you will also consider functionality. Orientation is important, and so easy to plan for at planning stage and so difficult to fix later.

Some details has added to the main post based on the questions asked. thanks

plans are very hard ti read and we need room sizes with length and width of rooms not square metres and where is the front entry?? and i prefer master bed windows facing north to allow for some more privacy and what is the distance from the house to each boundary..is there enough space for a clothesline or garden south or west of the house?

In Melbourne I would have alfresco on west side more protected from afternoon sun. Try and get some access to powder room from pool. A wide eave on western roof to front guest/living plus louvres on west windows

And don’t forget the pool shed to house the equipment and noisy filter

@oklouise . room sizes are big enough, beds are 4x3.5m, master 5x5, sitting 4x4, office 3.3x2.7, theatre 4x5.5, dining living 6x10m, alfresco 4x4.6m etc. Kitchen, WIP, WIR, laundry, bath all proportinally bigger, total 46sq home.

i dont know why its reduced the quality so much. 1.2m to south, 2-3m to north, 8m where the pool is, 6.5-9.5m to east(front), 3.5m to west, so there is enough space around

@kate alfresco - that would be next to kitchen, only windows facing west is the guest or sitting, will have eaves around the north side. havent thought about where to place the pool pump

we need room dimensions not squ M to work with, can you provide block dimensions as well.

@siriuskey beds are 4x3.5m, master 5x5, sitting 4x4, office 3.3x2.7, theatre 4x5.5, dining living 6x10m, alfresco 4x4.6m etc. Kitchen, WIP, WIR, laundry, bath all proportinally bigger, total 46sq home. land is 842m2

Can not work out on the blurred plans where the entrance from garage into house is. Can you please highlight. Personally I would,not have minor bedrooms, which are used all the time, backing onto to the garage. Noise factor and the hallway would be always used for going in and out of home. I would put utility rooms, theatre room, office, WIR and bathrooms on the wall of a garage, not bedrooms. Where are the entrances to bedrooms? I would put guest bedroom at the front, not on the alfresco wall. I would have master bedrooms facing north away from pool. Again noise factor and privacy.

Agree with Kate, have the pool on south west side and alfresco also. Have the living areas on the north east side. Can have wonderful windows opening up to north winter sun and morning east sun. Western side can protected by alfresco.

A overlay on your plan of my ideas. Orientation is the key.

Your first plan is my preference of the 4. The alfresco is both close to kitchen for outdoors dining and protected from the western sun. The living has view of pool and viewed from front door with guest room tucked away. Make sure you consider the need for a pool fence all the way around the pool unless it is raised. A wall can be part of fence . You Can’t have a door from pool into house.

And create a shade zone on north side of pool for lounging.

Couple of extra options i thought to get make the roof line more simpler without having too many cuts.

Why such massive rooms, it all costs to heat and cool, and all the time spent vaccing. Australia has the biggest houses on the planet, I do not understand why those fortunate to be able to afford it are not investing in good quality functional and sustainable architecture instead of mere size? You didn't answer the questions about who the house is being built for etc. For example do you regularly have guests or is the second ensuited bedroom for extended family? Does it serve a purpose? Or is there a guest room because 'guest rooms' are now a 'thing'?

builing for ourself, with 3 kids. yes guest is for extended family, my mother or my wifes. mostly get used.

we still need to know total width and length of your block as well as location of front entry to the house and the garage ... it's very unusual for the garage to project so far forward of the main house.. have you confirmed location of garage with local council regulations?

its a 15.58x54.31 corner block. garage is at the back. hosue is facing east and thats where the entry(porch) is.

where is "back" do you mean that the driveway is from the long side of the block and the front entry is through the alfresco??....a rough hand drawn sketch of the block showing the location of the driveway, both roads and the front entry porch would be clearer than what we have

Oikl my guess is laneway along short west side and frontage road on east

but could also be at the end with the office and porch???

based on your original plans my suggestions include variations with a much simpler gable roof (and maybe a raked ceiling in the kitchen living areas?) ...alteration in the size of some rooms to include storage, mudroom and pool change room and keep overall size within the 46squares (427sqm) but there's ample room to reduce the size/cost without altering the basic floorplan too much...hopefully these plans won't be too hard to read

the same floorplan could be reduced by more than 6 squares or 55 sqm and still provide a comfortable home with more gardens and @ around $5000 per sqm that could be a very significant savings that could be invested in better quality fixtures and finishes like a gable roof and raked ceilings, Solar Panels, quality built ins, improved insulation, better windows, cheaper running costs, landscaping, etc etc

We have decided to go with this plan.

Great
A couple of comments. Both powder rooms seem tight when inside opening door.
Add doors in hall at each end of great room to zone off areas for noise and heating. Also to pantry for noise - great if using blender etc.

Hard to read your plan can you post a clearer view

you need to click on the plan to see it big, not matter what i upload th esite reduces the quality.

Tried that but still hard to see details, great to see you have made a decision, all the best with your new home

it was great help from the community, we took most of the suggestions onboard and it also helped to make some decisions like the location of alfresco etc.
