Industry has such workflows but they currently revolve around heavy products like Tekla Structures, Grasshopper/Rhino, Revit, Archicad and so on. I'm not aware of "light" version for "non-professional" residential projects. The thing about buildability is that when you want an _actually_ buildable model you want vendor components(windows, curtain walls and whatnot), manufacturable details and so on and those come out of the box AFAIK only in a product like Tekla Structures. Industry is reaching a stage where the house that is to be built on-site can be actually modeled in 3D - the current WOW is mostly that the 3D model is used to output 2d drawings and then manual building ensues as it has for centuries/decades with details that are not exactly right, lots of manual fittings and ad-hoc installations if HVAC and so on. BIM 3D models are only now becoming detailed enough with enough cross domain support to actually model the whole thing.
