Thanks guys for your reactions.
The house and base are scratchbuild using (plaster covered) foam-carton, plastic strip, wood and pe (balconies, from Scale Line). It's really not that hard, it's just takes (an awful lot of) time!
giving up on it? sorry, it might take me (light) years but I'm gonna finish this one (I know, I know there's still a lot to do; vehicles, figures, water, boats etc etc)
kind regards
Mark
