Where is north south east and west?

The living area (dining and lounge) are not in proportion in size, for how many bedrooms you have.
Remove the powder room from the dining room. Include it in the study area. Then the powder room door can open from hallway, and occupants will have privacy, instead of being part of the eating area.

I’d look at moving powder room, swap dining and living, increasing bedrooms to 3 m width and increasing size of alfresco to 4 m to accomodate a table .
Do you need 4 bedrooms plus Study?

An Shhireen, are you at the most you can build on your block?

Therefore, Are you looking for internal suggestion changes only?

internal changes only, the patio is in North and alfresco in south

Okay, thank you for compass points.
The minor bedrooms and family, run along the east side, so those rooms will get plenty of light into them in the morning to around 1pm. Bed 4 with the north window, will be a lovely room.
West side main bedroom is protected from the west sun, with having the small window, on the south side, so that is good also.
Enquire about installing skylights or solar tubes into the passage way. This will light up this area.
Otherwise, you have done the best you can with block size and orientation.
But, I would still relocate the powder room out of the dining room. Or eliminate that toilet. Make the toilet near main bathroom a powder room.

patio is north n alfresco is in south

if I have to remove a bed room which one should it be

The one you don't need.

Genius....

I would re-evaluate my brief, my budget and my site. It is another case of trying to squeeze too many rooms into too small a space and compromising the living space. If you draw furniture to scale in your living room then you will see that it is undersized for a four bedroom home.

With the best orientation going to the garage door and bedroom 4 I would look at a complete redesign by pushing some of the bedrooms to the rear, and a central courtyard to give you an opportunity for north facing light to a living room.

There is nothing nice about the current design and will feel like an apartment with little resale appeal. The designer has shown no flair or imagination in this "gun-barrel" floorplan, and is a variation on a concept that has been around for centuries.

But your biggest problem is the number of rooms. Do you really need 4 bedrooms plus a study and 2.5 bathrooms, a long wasteful hallway, and only one modestly sized open plan living area and kitchen on a narrow block?

I would start again with a smaller brief and a designer who can challenge your thinking about what good small house design actually means. Small house design is the hardest to do really well, so don't use a large house designer.

any small house reno designers here??

I agree with DR retro... it's just too big for the block! A garden is a special thing and worth investing in. You'll need some outdoor space. Do you need all the bedrooms? I really like an architect in the US called Ross Chapin and he specialises in small houses and what he calls pocket neighbourhoods. I have a limited budget and I've learned a lot about how to scale down living spaces. He often will replace what people use a whole extra room for with a nook, or widen hallways so they can have nooks for a study spot that might be able to be closed off if a guest comes. Or little mezzanines for extra storage or a grandchild guest room. He replaces a dining room with a booth attached to the kitchen. Not saying you have to do these things, but its worth considering how you can maximise the space that you really will use. i've often rented houses without linen cupboards and I ended up downsizing linen to just a winter and summer set each, stored in the bedroom. My family, we've realised can live without lots of bedrooms each, but we desperately need a few large living areas, we homeschool, and do lots of crafts and art and boardgames. Other households could be the opposite.

I m looking for any interior designer for small homes in Australia, preferably in Sydney

An Shhireen, don't get an interior designer to try and plan your new home, especially if you have a narrow block and with the constraints that you have. Designing a new home is more than superficial finishes, it also involves structure, BASIX, roofing, light, orientation, service infrastructure and lots of other things that are beyond the training of most interior designers.

You asked if I had any small 3 bedroom, 2 bathroom floor plans, which I do. But they are individual designs that I have completed for clients. I don't hand out floor plans that I have designed for other people, who have paid for my design services. As they are designed for my clients my designs make the most of the opportunities of their respective sites in respect to orientation, their views, privacy from their neighbours, and even the crossover location. These will be very different from your property's constraints and opportunities.

If you would like to know more about how my design process works for small homes please feel free to contact me directly, as I have clients from all around Australia which I talk to via Zoom.
