Dollhouse Stairway Surround

I carved the posts out of 3/8" square pieces like the one on the left (a prototype).  The "surround" will fit into the posts as illustrated in the picture on the right.

This is the gist of the stairway enclosure.  I will glue it together,  stain it,  and then install it in place.  A similar construction will be made to fit the staircase on the lower level.
