Hi there...this is the first time that I have written a question. I am currently retrofitting/remodeling (kitbashing :-)) a 35 year old Dura Craft Colonial dollhouse which my parents had built for my daughter. I recently purchased one of the lovely curved staircases to replace the one which had come with the kit. Unfortunately the staircase did not contain information regarding the size of the opening required at the top of the stairs. The original Dura Craft opening is too small.
i am concerned that I will make a “huge, irreparable hole” in my attempts to enlarge. Has anyone out there installed one of the curved staircases who can provide some dimensions? Thank you in advance.
