Hopefully FOSS software In architecture will get popular soon, so that when I get to build my home I can get files from my architect, make some adjustments and send it back for discussions and verification. It would be cool to truly “own” design of my own home (also I would overoptimise and overengineer the design w.r.t. to energy efficiency air flow etc. more than an architect reasonably should and could due to time constraints).
