Great job here! I really like this house a lot. You've come up with an original design that is indeed very easy to make, with common pieces. I LOVE the details on the ground around the house. They just look great with again, such a simple design (green 1x2 plates and grass) but it really pops. That and the goat, and barrels and pumpkin patch
. I think you're Cuuso idea is right on. I have been considering doing a castle version of this where there would be 3 sets, for example a tower and wall set, a gatehouse set, and some third set (undecided at this point). The idea would be that if you bought, say 4 tower sets, a gatehouse set, you could build your own castle, but it would be designed to be expandable, so you could use, say 3 tower sets, or 6 tower sets. Each set would also have an alternate build, so maybe the gatehouse could also be used to build a barracks, or something similar. I think your idea has better marketability though. I would like to see the other build options be buildings other than a house though, as that may be more appealing to the public? Excellent MOC and idea though. I love it!
