Shed home / liveable shed/ class 1a

*We live in rural WA

*council allows shed homes

*only custom builders where we are but WAYYY out of budget for a tiny brick house

Hi All, we are looking at building a shed home (class 1a) a livable dwelling, the kit we’ve been quoted 120k for a 12mx30m this includes delivery, install and the slab for a standard shed so we would need to pay to have engineered to be 1a - what would we be looking at cost wise ?

We where hoping to get a local builder to do the install to make it habitable, we are extremely time poor (fifo hubby) and 2 kids under 2.

We ourselves can do the painting, floor boards, kaboodle kitchen, landscaping and any earth works.

Do you think we could have a builder do a habitable extremely basic fit out just to pass council for under 300k ?

Then over time we can do the rest ourselves ?

All and any advice needed and appreciated!
