there is still some space. I´m sharing a "man cave" with my father under the roof of my parents´ house, there are most of my father´s Luftwaffe planes, the rest is spread all over the house. Thank god most WW1 and WW2 subjects don´t need that much space. Only built few bigger WW2 and post WW2 aircraft, which are my interest. When I get more into modeling back again I´ll have to make space for the big jets, maybe I´ll adept one of my former youth rooms. Also started to take most of our armour collection and some jets to my appartement, where I have a "mens room" with enough free space on the walls to build up shelves.
I really gotta start building again to support my father, so that the many kit boxes that are still there get fewer and make room for built up models
as someone always states here: It´s only a hobby
