    Depends on if you're in the middle of the desert or closer to a capital city.

    we are building a granny over double garage 120 sqm

    This doesn't sound legal.

      i agree, physics says no

    please measure again, most double garages are closer to ~6m x ~6m = 36sqm.
    further, please confirm your take on 'brick veneer' - is that just a single course of bricks as both interior/external walls, or is there something additional on the inside.
    too many variables. photos may help.

    • JIMB0 on 05/03/2021 - 11:09

      Minimum size for a double is 5.4m x 5.4m = 29.16m2.

    Member since 7 hours. Welcome to OzB free consulting service.
    It is a pretty poorly structured request, insufficient and inaccurate information. So, is you are not an owner builder, then are you the builder, or asking for a friend?
    I would suggest first do some more research then make another post. Happy to help, just don’t look to take advantage of anything free.

      I agree it's pretty basix.

    You can build a whole house for less than 250k… or could pre-covid.

    We are building a 4mx4m room on our 3rd story. It's basically adding 3 walls and a roof plus power (it was a store room).

    We are doing this across 4 residences.

    So far it's been $24k in "development" costs. I think it will top out at $45k including our project manager costs. The actual build to lock-up will be ~$250k. Carpet, paint, etc will add a little more.

    It works out at $75k per room.

    Why hasn't the granny flat got a kitchen?

    • spal on 05/03/2021 - 14:10

      Probably granny gets meals on wheels or Uber Eats. Well the location makes better sense now, closer to the cars to get meals.

    Why hasn't the granny flat got a kitchen?

    My first thought on reading the post.

  • Euphemistic on 05/03/2021 - 14:26

    Ao you’re building the granny flat AND the garage?

    • Logical on 05/03/2021 - 23:49

      It is a 2 level structure, garage space on ground floor and granny flat on first floor.

      • Euphemistic on 06/03/2021 - 06:16

        Yes. I get that, but wasn’t sure wether the garage was existing.

        • OZWLD on 06/03/2021 - 17:37

          No both garage and granny flat r new

    be careful that garage has plenty of ventilation, and that living areas over and next to it have carbon monoxide alarms

    so many accidental deaths from cars left running by accident in garages that are attached to houses

    Cost per sq meter will be between $2,000 to $2,200, as such price range for a 120m2 two level build will be between $240,000 to $264,000 inclusive off all designs, approvals, building costs, builder's profits and margins.

    Where are you located? Have you had a preliminary chat with local council? Some councils are positive or neutral on granny flats, whilst others are anti and obstructionist.
