Non-degree furniture/ interior architecture courses in EU?

My background is in mechanical engineering, but in my spare time I build furniture & sculpture out of concrete, metal, & wood. My methods to design so far have been to make up dimensions & hope for the best. Some pieces I’m been proud of… others are a mess of disproportionate components. So I’m looking to learn some design principles (ideally applied to furniture & interior architecture) while living in a European city for a few weeks / months. Sort of an ‘educational vacation’. I searched the “schools” forum but couldn’t find what I was looking for. Anyone have any tips?

Not exactly furniture focused, but this looked like fun to me. Pretty cheap too, $2500 for a 10 day course including what looks like pretty awesome room and board:

Wow Thanks Scott. This is EXACTLY what I was looking for. I’ll definitely take a detailed look.

Still open to other suggestions if anyone knows of others.
