I wish I can join that community posting.My S.O. and I love interior design so we're always experimenting with the furniture and wallpaper in the game. Having someone to take inspiration from helps a lot. Having a community posting what they've created is major brain fuel for creativity. This applies to not only the house but the farm ground as well. I see a lot of players' farms on social media which makes me glad that the forums are here now. Hopefully we'll see more community creations on here.
In my current run I've changed my design every year so far. Normally I try to keep everything very square and efficient. I'm in winter now but I have a plan to sort of make things look a little more natural and not worry so much about maximizing space come Spring.

(Although some people seem to have a natural talent for designing these things)The trick to having good far design is to just keep trying new designs until something sticks.
