During the sixth module of my study, I created a Japanese house 3D model. It is complete with a self-modelled interior and an environment around it and a day-night cycle.
A set of doors can also slide to open and close, which you can try for yourself, in your browser, in a small online simulation I made.
I also rendered some images for it (which took quite a while), which can be seen below.

It may take a while to load. Also, please note that only the sliding doors have collision with the player.
Use your WASD keys to move.
