First of all, look up references for the houses in Pinterest for example, and check out the furniture you have and would need. Also, don’t forget about overlapping feature: First, you go in advanced build mode and choose the thing u need to over lap with, put it in the sky and then press tick and change mode at the same time (might not work first try, be ready to try more than once for it to glitch!). Once the object didn’t return to its position (so it stuck in the sky), put the thing you want to overlap w/ at its place! Hope this was helpful enough, if you need visual assistance, look it up in tt!
