If you want to do it yourself and haven't got the tools, check out the Home for Do it Yourself --
Haus der Eigenarbeit: (Do it Yourself-House)]http://hei-muenchen.de/They have rooms that you rent by the hour and trained carpenters, electricians and whatnot, and all kinds of tools. They give lessons too.
More for the search: not Eigeninitiative, Eigenarbeit -- DIY.
They have rooms and tools and space for: hobbies, ecological building materials, restoration (of what i don't know - books? paintings? furniture maybe?), carpentry, ceramics, jewelry, textiles / fabric / clothing /sewing, upholstering / upholstery, metalworking / metal shop, papermaking, sculpting, bike repair. And their website's not in English and it's hard to find online even if you're searching in German so I put it all here for the hell of it. Maybe they'll hire me to fix their site up a bit.
