You have posted the same plan several times in the last 2 months, Patrick! And you have had different budgets in the posts, $150k to $400k. And different things you have wanted to do.
Would be good to confirm your budget and wish list.

Yes sorry - :(

Our goal is always to have brand new interior, create more spaces on our existing land but we just have $400K.

Hence I was intended to KDRB for 400K but after I have been talked to few builder $400K does not qualify.

We were also look for adding a second storey on top but looking at $400K is also a "no" since it does not qualify / enough $ to have ground-level renovated at the same time.

And now - after we talked to council and we realised the setback limitation, so we might only go via a major reno the existing floor space and see if we can knock off walls and create more spaces.

We look for 4 beds and 2 baths. we do not mind to get rid of the laundry room and set cupboard alike outside for washing machine & dryer.

You will need builder to quote something like this might work with
E being the 2nd bathroom or en-suite.

"And now - after we talked to council and we realised the setback limitation, so we might only go via a major reno the existing floor space and see if we can knock off walls and create more spaces."

Surely block isn't exactly L-shaped following shape of house? Area marked pergola is presumably buildable, and is shed shown in position?

@Kate thank you for suggestion and we never thought about this.

@macyjean it is looking like the below. Shed is not shown in position.

4m rear setback at the hills district is somehow blocking our ability to extend at the rear.

Making it a 4 x 2 does not leave enough living area

As commented on another post about the same thing. Convert your garage to a bedroom and ensuite.

@oklouise I am extremely keen if it fulfills western setback requirements and my budget is able to achieve. What kind of option for (e.g. the roof?, rendering?) if we are keen to see it seamlessly integrate into the block while we look at it from external)?

HOUZZERS can't attempt to answer your questions until you provide exact dimensions of all rooms, details about existing building materials for roof, walls and roof including external photos of the front, back, sides of the house and overhead view of the roof and exact precise setbacks needed from every boundary and you can get that from local council... otherwise we will just keep making suggestions that you will still need to discuss with council and a builder and a limited budget will mean that compromises will have to be made regardless of what you would like to have

Agree, we and you are going around in circles. Go to the council. Get the setbacks that are correct for your block.
Then you have a base to start with, instead of dreaming and then realising the land and budget for changes are not feasible.

@oklouise@dreamer this is so true that precise dimensions / block measurements are required. We have got the doco and realized the setback requirements - 6m from the front and 4m from the rear. What is blocking is that we have a tenant lives in there and without disturbing their lifes it is had to arrange for somebody builder to get in to measure and evaluate.

P.S. Given the current COVID lockdown situation we were decided to renew the contract with the tenant for another 6 months and see what the situation will be. But we are keen to get prepare and explore what we can do upfront..... hope it clarifies my situation.

Patrick, you can ring your Council and ask them re the setbacks while you are waiting for access. I’d be particularly asking them to clarify the 4m rear boundary setback. If it applies to the entire length of the rear boundary then you will have limited opportunity to extend to the side also. While on the phone I’d also ask about the possibility of carports within the front 6m setback. They can be done in my Council area with an approval process. This would then give you the option of the garage conversion. You really need this info before you do anymore planning. Good luck.

you should be able to ask council about required east and west setbacks and they may also have copies of the original floor plans and you should be able to arrange a site inspections through your rental agent at a time convenient to the tenants and would be well worth investing in a professional surveyor to make an accurate site plan that will critical for any future plans and no point guessing what's possible until you know exactly what you have

Is the corner of Bedroom 4 on the setback? Drawing a line out from there parallel to the boundary might give you enough of an idea to play around with some concepts?

For proper plans and quotes, I agree with the advice to seek original plans and more detailed advice from council.

What "doco"? General setback requirements? What about easements for that particular block?

The existing materials, etc question is important. And how old is house? If it might contain asbestos that needs to be addressed before proceeding, for both safety and budget.

Thank you all @oklouise@bigreader for your advice.

You might have seen the engineering sketch below and perhaps I need to pay for a more precise drawing from the qualifeid surveyor.

@macyjean doco mean documentation. :) Yes indeed the house was built around 70's and I know it cannot be ruled out the existence of asbestos.

Easement wise I cannot see easement mentioned in title search, Plus, reason I don't have too much concern as you can see on 2nd picture (in which I captured from the contract) below.

I came across a situation once where an easement did not lie within the general setback boundaries, which is why I thought of it. That looks like an easement at the back but it's within the setback. I'm not sure your shed is legal? It would not be in my council area.

Can you extend out from master for en-suite?

Hi all, I am unsure if you still able to see this update on this post, (rather opening a new one for identical topic)

I decided to do ground level extension and eract additional structure on the deck area (New kitchen area shown below) . I have been told by the builder it will be very expensive to demo the wall against the laundry since it is load-bearing.

They come up with the following suggestion on dining and living. It looks really weird but I am out of idea on its alternative.

Any suggestion is welcome :)

Exterior walls are expensive to remove but not impossible. Did they give you a figure so you could make an informed decision or just tell you it’s too expensive? As drawn it’s an awkward space with neither the dining nor the living working well. In your earlier posts did we discount using the garage? It looks like it’s under the same roof line and would be the obvious place to push out for space.

@bigreader thank you for your prompt response ( as usual ) - I was informed it is just too expensive and without telling how much cost it will be incurring if going ahead. We are super keen to keep this tiny garage for my lovely vehicle - this is the only tiny space for him though.

Here are two very rough suggestions using the space in your most recent plan. One would involve moving the kitchen inside the current house. Blue = kitchen / built in storage, green = living, maroon = dining.

@kateinhobart I find your suggestion (the bottom one) is inspiring! Thank you!
