To start our hexagon house-tiles series we made wood floor tiles.
These wood floors come in 2 patterns, with the beam-ends connecting either straight or diagonal to a hexagon-side. This way the wood floor can be laid out in any direction you want.

Our tiles are made for about 32mm scale, but we made them a bit larger (gloomhaven size-ish) because the baseplates of our 28-32mm sized medium creature mini's did not fit between the walls in a small alley.
