Love this. Can you do any kind of design on it?

It seems (the design/layout) of the building form is progressively getting bitsy and tight ( like in a typical volume build plan) in the main living/kitchen/dining/alfresco area rather than being elegantly resolved with the flexibility potential layout usually exemplified in a custom home .......what is going through my mind is what exactly is the function of the external space to the west which is not at all connected with the internal.....I'd be considering configuring the ground floor better to maximise/exploit the northern aspect...It would simplify the whole thing, be more efficient and less block-like with building chunks cut-out/doglegged just to suit a table or whatever..........It's like the requirements are being somewhat forced within a particular set building shape rather than designing it so it all flows more naturally/balanced and is more elegantly linked and maximises the available land/space/aspect...form (should!) follow(s) function.........may I also comment that perhaps some care/caution/discretion should be taken when uploading documents clearly associated with a particular designer on forums (for public critique/comment!) ;)

If you are in Brisbane would rec Cullens Cubbies & Forts. They custom built a cubby for our family that is still going strong 10 years later and our older children still like to hang out there. We particularly wanted one with an large open area that even as adults you could stand in. Did not want it enclosed with the hot summers we experience. Kids have had sleep overs in there and many a party hangout. Google them :)

I would check with your Council first as to the requirements for permits as you’re altering a structural part of the house. And to get the permit you’ll need plans. A qualified builder, which you need, won’t look at the job until you have those two things in place.
