Part 2 - Special Area
When you look at the middle of Figure 1.1 on the previous page, the colored middle tiles are an area that can sometimes have house blocking items inside it. Not trees or large rocks, but those thorny looking bushes, house blocking flowers, small rocks or uneven terrain.

Uneven Terrain has to even out before it leaves the middle area. Take for example a keep, its base is level, but a lot of keeps have uneven terrain in the middle and through out. In addition I placed a log cabin in which the middle covered up a fairly good size hill, it was gradual 3 tiles up then 1 tile level then 2 tiles down if I recall, you get the idea right? Don't just pass by that spot because you can see a small hill.

Log cabins may have the advantage when placing over tough terrain, maybe OSI intended this to be so, think about it, you have to walk up 2 or 3 tiles to get to the door, so the floor is a whole 2-3 tiles above ground. hmmm.

Small Marble Work Shop Ver Small Tower

Since the footprint of the Small tower [8x7] is different from the Small Marble [7x7], when checking for a spot, check each spot for both the marble and the tower.  Basically you can fit more "stuff" inside the middle area of a small tower.

Figure 2.1 we have a nice spot I found one night, It has a lot of "stuff" that people think houses can't be placed over.

The red circle means I can't put the West wall of the stone over it, but it can be next to it, since you can walk over those flowers.

Green Circles mean they can be inside the stones middle area.

Figure 2.2 is a transparent display of the house and what is under it.
Figure 2.3 is the resulting placed house.

Take a special note of what Figure 2.1 has on the ground. All of those plants, rocks, and bushes can be inside the middle areas of homes. Figure 2.4 shows some pictures of which plants can be inside. As for rocks, it depends on the size of the rock. Most can be in the middle area. However a rock on a slight hill could be a problem.
