Also, the area in red is where we are hoping to extend.

Thanks

I assume that north side is your frontage. You need to check with council what setback you must have

Yeah that is north. Council said we could build as far as our neighbours garage which is about where the red line is.

I would simplify your extension footprint to a simple rectangle. Avoiding angles and minimising the interaction with the existing building will minimise your costs.

Thanks!

I am concerned that if we extend using the same angles as the existing house, we will end up taking up alot of the front yard and also the driveway entry would be very close to the corner.

What is the distance from the front corner of house to the red line you can extend to
?

about 15 meters

You could keep laundry where it is taking up some of kitchen. Kitchen diner become master then the new front wing is new living kitchen.

first step would be to arrange for an accurate site plan to confirm precise space available but using approximate angles and dimensions and allowing for the angled building my suggestions inlcude the new master suite, double garage, extra study/bedroom, separate laundry and powder room with some variations to the kitchen and retains the original front and rear carports

Wow, thanks so much for doing that! What software do you use? Do you think there would be an easy way to do internal access to the garage?

Thanks

internal access from the garage could sacrifice north facing light into the new ens, master and living or steal more space off the garden but could possibly be achieved by adding a long narrow space at the south side of master but depends on how you want to use all the spaces eg what size garage, how many bedrooms, would you like a bigger kitchen, different dining, laundry or bedrooms or? but i cant read all your dimensions... please measure and confirm all the room sizes and enlarge the plan and share more photos of the existing driveways and the house and can you measure from the outside corners of bed 1 and 2 at right angles from the house to all fences ignoring the existing big carport... i use a very basic vintage software program called 3D Home Architect but no program creates a design it only makes it easier to share ideas and we also need to have knowledge of basic building practices and suitable shapes and sizes for proposed extensions or renovations especially for roofs but i suggest that the most useful plan you could make is an accurate site plan showing the house placed on the block with all the distances from the existing house to all boundaries to show how much space is available and that will help HOUZZERS suggest alternatives ideas

Thanks so much!

Basically our wish list is, master bed and ensuite, additional living space, study/bedroom, garage (ideally 6.7m x 6.7m but minimum 6m x 6m) and laundry.

Our 'nice to haves' if possible are: additional bathroom/powder room and if possible, a living room opening to the back yard in the south-east corner. Fully understand this may not work.

We are definitely keen to utilise the carport to the north of the lounge as an internal area and initially wanted to have the master bed/ensuite that end of the house but we cant increase the length of that roof line as we are already as close as possible to the set back so assumed this would be too small for the master bed.

We have actually already changed the layout slightly in the existing lounge, kitchen, dining by opening this area up and this is not reflected in the plan but we are pretty happy with these areas.

Thanks so much for your help. What you have drawn is what we were hoping would be an option but wasnt sure about all the angles etc. Looks great on your drawings though.

My first thought was to change everything to take advantage of the Northerly aspect, dimensions aren't exact but could be worked to fit your site, basic idea follows

That was my first thought as well. Change the old house for the bedroom master suite, laundry and the new extension has the kitchen living. It just depends where you wish to entertain. Out the back or in the front yard which gets most of the sun throughout the year. I have NORTH as running towards the street entrance, where the garage is proposed. Siriusky design will still get the northern sun though. But also the west afternoon sun, which would be good in winter.

Another option, as it appears from overhead shot, that you have a drive through from north street to the west street, with exisiting crossover on the west street. Build your new double garage as a separate building on that west street. Leaving the east side boundary for your new extension. Just depends which road is busier etc. and also build ratio allowance percentages. I have drawn a rough placement of double garage in purple.

When buying an older house the first thing that most consider doing is a new kitchen but when this includes an extension this gives the opportunity to improve the flow of the whole house plus take advantage of the aspect. Moving the kitchen in this situation can be cost effect as well.

What is the distance from the house to where the garage starts allowing for set back from the street

That’s great! Did you have any suggestions for making the other carport internal space too? That is kind of an awkward space too

the carport could be converted to a separate rumpus or MPR with a concrete slab at ground level with access through the original entry porch enclosed to allow all weather access and use the old driveway for an outdoor sitting area and/or maybe use my new corner study as an alternate location for a new laundry to allow more space in the kitchen but it will need careful planning of a new "front" gate and footpaths to show clear directions to make sure visitors know how to find the "front" door.. attempting to access the new rumpus from the family room would create challenges with doorways, changing old external walls, ceiling and floor heights so i would simple enclose the carport space and keep it separate from the main house and you should be able to find inspiration from many examples of similar era homes (eg Pettit and Sevitt) that had timber cladding combined with blond brick walls BUT it would be very useful to organise a site plan showing the house and accurate distances to all boundaries, scale sized buildings, existing driveways, front gate, location of street address, power, waters, sewerage, precise direction of north and any trees that you would keep...an accurate site plan and more photos could help inspire other options or confirm that my suggestions are either possible or not

Thanks oklouise, this looks great! What you have drawn is pretty much exactly what we were hoping for but just lack the expertise to create a plan. We just wanted to see if it was feasible before engaging a designer.

I really appreciate all your work and advice, was far more than i expected!
