This is a recently completed Charleston Single House that I designed and am in the process of parting out for my next Bricklink project.
Modeled after the predominant home style of Charleston, South Carolina, USA, I tried to keep the look of the house architecturally consistent while adhering to the confines of the standard modular footprint (though the left roof line and a couple of tree branches do extend 1 stud past the 32x32 stud boundary).
In keeping with the style, the house is only one room deep and is actually situated sideways on the lot, with the front door opening up to a porch and the main entrance to the house facing the courtyard.
The first floor contains a full kitchen and the stairs leading to the second floor. I tried a couple of times, unsuccessfully, to find the space to make a small breakfast nook to my liking, but I may work that out in a future version.
The second floor contains the living room, complete with sofa, chair, table, TV, bookshelf, and access to the balcony.
Lastly, the third floor contains the bedroom, bathroom, piazza, and of course, the roof.
Additionally, since I am building this for myself, I stuck with only using widely-available brick and color combinations. As such, it is constructed of mostly 1x2 bricks in medium blue, since it is easier and cheaper to buy 600 1x2s in that color than it is to buy 300 1x4s. The rest of the 3,408 parts are pretty standard and easy to acquire.

Enjoy.
