Id like to suggest being able to place these 2 types of floor (Timbered & Half-Timbered) from an additional tile away (placement range would be 1 adjacent tile away from the player in all direction). The issue being its very difficult to plan some areas before you start placing down buildings and such, and then after something is placed you cannot place a floor underneath as you cannot get to the center of said tile. A prime example is Wooden Tanning Vat which is costly to make only takes up one tile and would look great with wood under it, but once placed you cannot reach the area to place floor.
