We got this wooden toy warehouse for my son’s first birthday and it’s a huge hit!  When he was little he loved opening and closing the doors and peeping through the windows, and his his big sister liked climbing into it very much (we went for the more expensive sturdy version with a bottom plate for this reason!).  And it’s still being played with on a daily basis, as a doll’s house, a shelter for the Schleich animals, or as part of a city.   And my husband and I like the fact that it looks really cool in our living room.  Very Amsterdam!
We got our warehouse at Sherwood on the Elandsgracht, but online it is sold at Spelmaterialen.nl.  Unfortunately they only ship to the NL, Belgium and Germany, but I also found a similar (and cheaper) warehouse at Toypost in the UK, and they will ship internationally.  Because I don’t think it will fit in your suitcase easily!
