I did something similar in 2020 when we constructed our sauna/guesthouse. Used a program called "LiveHome3D" to build out how what we were looking for, then exported as an OBJ and imported it via Google Poly into "Tilt Brush" on the Oculus Quest.
I also did some light simulations so we could see how the skirting roof around the building would allow light in for summer vs winter.
We have been very happy we used VR. It allowed us to iterate on what felt right, communicate exactly what we wanted to the builder, and the sunlight simulations have allowed it to be comfortably usable year round - letting light in during the winter, but keeping direct light out during the summer.
