Generally they're open on the back... The dollhouse is for sure.
Some of the sets had full walls, but not many.
Like I had the western sets which consisted of square houses you could link together or stack... Ala the old west and everything. Well, they were all open in the back for access... You could technically have walled those in but it won't work on the dollhouse i don't believe.
I saw someone once (9th WaffenSS maybe?) who did the dollhouse up as an SS headquarters or something... Had little Nazi banners and everything. Really nice set-up...
With how price the Playmobil is, you almost hate to paint the house up to look more realistic... it's ok, but a coat of paint on it would make it really sharp and realistic. But even the prices at stores aren't cheap really. Compared to the website Playmobil has they're cheaper, but not by a ton more.
God I'm still irked they make civil war dudes NOW instead of then. And in army builder packs on top of that!
