Need custom built wood house

Its been quite awhile since I have been on the forum. I am actually needing a custom built wood house for my rabbit not my chins but I have bought some before ( i forget from whom) for my chins that are nice and held up well and want to get one for the bun as I am redesigning her cage. Basically I am looking for some solid wood construction, something she can chew on if she wants. She's around 8 lbs, maybe something along the lines of 12 D x 12H x 15-20" long (her current housing is 24" x 48" and is going to be expanded to have a second story of about the same area. This house would work as both a hiding house and a step to the second level. Wood doesnt have to be super thick, just enough at least that she could stand on it without it breaking)



Thanks a bunch!
