The new minimalist interior design is great, I also used pure white wallpaper, light wood floors and the flat ceiling lamps to match the trim and the stairs. It's going to be fun decorating with this new interior design :3
I do hope they allow us to change the colors of the stairs, rails and trim to have other color choices in the future. Having no pillars already saves me dozens of slots from having to hide them. The trim also saves me dozens of slots as well and I'll figure out what to use for the windows but for now, I'm pretty happy with this new interior design. There is even space underneath the stairs in the basement, so that's also really neat. I'm also going to use all three floors and just have the basement empty until the furnishing limit expansion arrives to decorate :3
Oh, buy the pure white wallpaper, light wood floors and flat ceiling lamps from your local housing merchant since the MB already has people selling them for many times their cost of 5000 gil each lol.
