Basement Design and Layout

I am adding a basement to the Painted Lady Dollhouse nicknamed the "Frankenstein House". I'm using the left-over stairs from the original Le Chateau Dollhouse kit before it became the New Orleans Townhouse. I plan to attach the actual basement to the Painted Lady but the stairs will just bump up against the front of the dollhouse.

As always I start with a 3D foam board mock-up, I'm a visual person so I need something more tangible than a flat drawing. I created a template of the main floor that leads down into the basement as well. As you enter the hallway from up stairs to the left is the kitchen with a pantry in the rear and a door that leads to the outside. There may be a small powder room underneath the stairs. If there are stairs. I am going to have to reverse the stairs in order to give me the space I need, I really don't like looking at the back of the staircase, still working it out.

On the right of the stairs is another room which I think will be for the live-in help. The lady of the house looked like she needed some assistance around with the cooking and cleaning. They are both suppose to be maids but I didn't like the cook's outfit, so the one in grey is the cook. In addition to the dolls, I bought a couple of things for the Painted Lady Dollhouse from The Dolls House Emporium USA website but I will reveal those with the furniture.
