To save time, and not over-power the shorter side walls, I only placed one column at each corner.
Note to self: The more holes you place in a wall, the more flippin' columns you have to make.
The stairs to the porch, and on up to the roof. These, and all subsequent stairs, will hold a figure on a 25mm base. As stated earlier, I have nothing against using pre-textured sheet. Here you can see the 'O'-scale Dressed Stone by Plastruct.
When I started working on the roof, I felt the walls weren't tall enough. So I raised the roof with these 1/8" x 1/2" strips.
The original builders had two large entry doors, but later inhabitants bricked-up one to increase the building's living space.
Small side entrance.
The roof, which is removable, with the stairway opening. Something to keep in mind, there will be two large walls coming off both sides of this fort. The side and rear doors and windows will not be exposed to the enemy.
Looking down on the stairway.
The garrison's living area. The troops will eat and sleep on this raised platform, made of Plastruct's Oak Plank sheet. The three windows provide light and ventilation. (Remember, there are horses in here sometimes.
The floor is covered with Polished Stone sheet. That should stand up well to horses' hooves.
While I hand-scribed the flagstones on the floor of the Porch and the stair treads, I needed something faster and easier for the roof. Plastruct's Random Tile to the rescue. "Why the odd shape?" you ask.
To fit around the shooting platform and railings, of course.
