I also recommend sh3d to do exactly what you needed: got the plans of my home (straight out pdfs) fed them to an LLM and got the 3D version of it in minutes.
Then started plopping in furniture and such, wonderful experience. Then you can navigate your home as a "visitor" to get a better feel. Definitely more realistic than Minecraft for actual planning.
