Town House Extension parts

To extend Detailed Town House(http://www.thingiverse.com/thing:943662) i made some changes on a few stl files

Now it's possible to add the upper floors. Print L_Wall_1stFloor and I_Wall_1stFloor 4 times each and you can extend the building with an extra floor.

Next todo, stairs? or an elevator maybe? Sunscreens in combination with new Exterior_Brick_Clad parts.
