I'm making a new cottage dollhouse called Quintessential Cottage.
On this house I did the porch a little different by keeping the floor longer than the porch roof. I already wired all the lights with battery operated lights I bought at Evan designs: http://www.modeltrainsoftware.com/mi.html
The front and this side have premixed concrete used as stucco and also as carved out bricks. The timber is wood pieces.
On the other side, I used birch siding that I glued on vertically.
Inside, I did the downstairs ceiling light and the upper ceiling dark. I'm thinking this will make a great cozy cottage look. Both ceilings are Popsicle sticks, even the beams.
The fireplace will get these flickering lights put in to look like a real fire. I just hide them in sticks I find outside. Add a little moss and you get a pretty little roaring fire.
