I have found a kit home design I almost like. I would want some modification to the interior layout and also to replace the cladding and swap out some external windows for double doors.
The company seems to be open to some modification, but not on materials. They use Bunnings for their lining kit. I like Bunnings for purchasing tools, but am not interested in having their chipboard shelving, cheap doors, etc, in my house.
Is it okay to just buy a modified lock-up kit and have someone else redesign the interior for me, or does that pose a copyright problem?
