How much has the base building system developed over the years?

i havent played this game in a couple of years and kind of have an itch to come back and build some houses but im wondering how much the base building aspect of it has progressed since then. are there more tile shapes available to use or low slope roofing options? and more importantly have they expanded f2p furnitures at all or is everything still very much behind a paywall.

this was the last build i made before i stopped playing a couple years ago when the game felt like it got very stale. https://www.youtube.com/watch?v=DlTjBwOSHWo
