It's useful to know more. For example your reasons for the rear garage, which occupies what would often be the valuable northern aspect of the house, not to mention the expense and wasted space and potential drainage issues of such a long driveway. What sort of climate are you building for? What is your concern about Bedroom 4? If it is the western orientation you can extend the alfresco and/or shade it in other ways, but Bedroom 1 is in a similar situation so is it something else?

About the rear garage , and I haven't seen if it is drawn to scale , but its quite a tight turn , and it doesn't look like you have a huge amount of clearance -- it will only take 1 vehicle to have the front ( or rear if the car is reversed in ) 20cm off-square , and you'll get scrapes , whether it be a car or a wall or the door frame .

When I was a kid , we had essentially a 6 car garage ( in fact , it was bigger than that , as we'd have 4 cars , a boat , a caravan , a couple of farm bikes and a couple of kids bikes , and then heaps of boxes and tools and a ride-on mower and push mower etc ) . It was built at right angles to our house ( Dad used to say it was done like that because it was about 25 metres on its own -- if it had been added to the end of our already 40 metre long house , the neighbours would have thought we had money haha -- I'm not 100% sure if that was the actual reason ) similar to this design .

One day Mum drove down the drive , swung into the garage , was distracted and drove into the wall at the end of 'her' parking area . The car went to the panelbeaters , the builder fixed the wall , BUT he Ramsetted a huge railway sleeper to the floor a metre in from the wall ( apparently at Dads request -- not surprisingly , he claimed the builder must have 'just used his initiative' ) . But the bill was descretely paid and the sleeper stayed , and even though they sold the farm 20 years ago , it's probably still there ! .

It's a strata block with shared driveway on the right. This is front block. That's why the garage is there. We are building in Perth. The waste of space at the back of the garage is the concern and can't move bed4 anywhere so we can change living size etc.

So the driveway continues to other properties? It says reversing bay. But then Bedroom 1 is labelled ensuite, sorry, no, I looked again and it's m/suite. Can you post a larger plan, so we can see the dimensions too? So what I was going to say is I'm still not sure what you don't like about Bedroom 4 but vehicles accessing neighbouring properties past the other bedroom windows might be a noise/privacy issue. Also now you've explained it's a shared driveway it looks like a strange place for the laundry to open to. Do you need the storage in the garage? Or if you do can you not make the garage deeper to line up with the house, then everything moves further north and your living and activity rooms can be lengthened. Am I understanding correctly that you need 4 bedrooms but would like larger living areas?

The 4m wide drive way continues to other property at the back. There is 2m more in front of garage as reversing bay. Yes, laundry looks odd. I want to have bigger living space and Alfresco.

if the entry is moved to the eastern side how would you use the old entry space and front porch.. can the old front porch be removed and are there any restriction to alternate location for the prayer room ... and if you need a bigger living space and Alfresco that usually means enlarging the whole house.. what is the maximum size allowed on your block and do you need 4 bedrooms and a study and the activity room?

I gather there are cultural factors at play here , but the floorplan wouldn't be anything close to what I would do . I wonder about flipping the whole plan ( except the garage obviously ) and having the kitchen etc near the shared driveway -- I know that gives you a problem with the Alfresco , but a lot of the other rooms make more sense to me that way .

Even the garage I'd look at moving a metre or so left .

Some rooms seem big for the use they'd get , whilst others seem smaller than expected .

Maybe I'm weird , but the bedrooms all have at least 1 room between them and the next bedroom -- so you end up with a variety of views and sun direction , and fairly long walks to the toilet at night , and 1 bathroom for 3 bedrooms . Of course , they may not all be used all the time , but then you'd ask do you need them all , and if you do , do you want 2 or 3 'together' , maybe with an extra bathroom , and maybe a smaller study or activity room ?

Likewise , a few changes could mean the hallway could be reduced or deleted , or maybe just a wall to hide direct views of a bathroom etc . Likewise , theres a fairly large square 'foyer' near the prayer room -- that foyer may be for cultural reasons , but I can't work out it's main purpose ?

Just throwing some ideas around . . . . . . . . . . .

Why can't the double garage be at the street frontage. With front door also at street frontage?

pending extra information these variations add extra space to the living area, make the activity room a more useful space and there's enough space for a separate guest ens, more generous family bathroom and a new front entry with porch

I'm with dreamer, it's a pity that there's a share driveway running down the full length of the eastern side of the block, but does the garage really have to be out the back, dominating the northern aspect of the home?

This garage will rob the home of any northern light, making it darker & colder in winter.

Is there a chance to move the garage to the front of the home. The SW corner with a driveway to the street would be ideal, but even the SE corner would be a vast improvement.

If you can move the garage you can have your living areas to the north. They'll have great connection to your yard. Where they'll be light, warmed by the sun in winter, protected from summer sun by eaves. Currently the living areas will be very dark, with no northern light, only receiving some western light, will get very hot in summer.

Which brings me to the fact that two bedrooms face west. A bad idea, particularly for the master! These rooms will be hammered by the afternoon summer sun, & will be extremely hot in the evening. I'd be looking to redesign the home, to eliminate these problems. At the very least I'd be removing the western window from the master. Using a reflective radiant barrier in that wall, to try to reduce afternoon summer heat radiating into the master.

oh, I meant to link this brilliant government website,

https://www.yourhome.gov.au/passive-design/orientation

I'd recommend you read it all, starting with the sections about orientation & passive design. Orientation is critical in achieving a comfortable, energy efficient home.

If I was going to be investing my life savings in a home I'd certainly want to make sure I was happy with the results. I'd want a comfortable, energy efficient home.

In your plan a bathroom with two doors is always a concern. If occupants forget to lock one door, and the guest walks in....a bit embarrassing. Oklouise has solved this issue, much better.
Have you a large family, or would relatives be always visiting from overseas? You have three living rooms?
A shared driveway is also a negative. Visitors of other homes, unaware, leave their vehicle parked in front of your garage, and you can't get out etc etc..
If you have room in the front for the garage and entry, I would be changing the design to move garage to the front, and have more home opened up to the north. This will give you a dedicated driveway, not shared. Unless the design has been done this way because you don't have enough metres at the front set back for a driveway.

Hello everyone, sorry I couldn’t post it here before. Thank you all for you suggestions. It helped me very much. My husband and I, we both work from home few days a week so we really wanted separate study. I really liked the idea of front garage so asked the builder to draw another plan. Let me know your thoughts about it.

Much better, but why can't you have the entrance to the garage directly from the street, instead of at 90 degrees.?
Make sure you install either external blinds for master suite or good block out curtains. The west sun in the afternoon will make the room hot.
The same with the front living area, and the back dining room windows.
Otherwise much better, and gives you a good sized outdoor area.

@dreamer, we had to use the common drive away on the right as council is not allowing the separate driveway.

Much better. And now you get to use the valuable northern side.

Add doors, sliding or swing in some cases where you have dashed lines and it’s perfect

We were actually thinking to change this plan as the hallway is very long. This is the another one we’ve.

I'd rather a long hallway than missing out on the benefits of northern orientation for the living areas.

What is so long about the hall. Now what is planned on the block to the north.? Need to consider the shadows it may cast. Will it be 2 storey? You may be better having your covered alfresco on the northern boundary to maximize sunlight into your house,

Sorry, don't like that last one at all!

No winter sunshine into the living areas (the alfresco area will shade them. Northern aspect wasted on minor bedrooms. More bedrooms facing west, they'll get very hot in summer.

You could make a feature of the long hallway, with interesting artwork, like a gallery. The addition of clerestory (highlight) windows will keep the hallway light.

Another unusual option could be to move your side entrance even further down the home, to shorten the distance between the entry & the living areas. This could allow you to move the master to the SE corner, a much better aspect for a bedroom than west.
