Dude this is awesome, love how you separated the floors too, lighting was real good to. only issues I see so far is you left your glasses in the bathroom floating over the tub on the main floor I think, and a lack of surface colliders for things like the beds, chairs counters tables etc etc. other than that great work. I'm gonna use it. I have a few ideas for it.
thank you i have built and designed the house myself, have worked on it the last 10y =S
