I am often asked about how to start a modern dollhouse hobby on a budget. I'm not an expert and so my automatic response is typically "roombox", but I forgot that I once used an IKEA CD cabinet with sliding glass doors as an open plan modern ranch dollhouse. It worked well. It also was quite space efficient since it was mounted up on a wall. The recollection sent me to the IKEA website where I found two cabinets (pictured above) with sliding doors that would make nice inexpensive modern dollhouses. The first image (my fav) is the Odda wall cabinet for $69.99 and the second image is the Grimle cabinet priced at $99.99.
