Here's a nice plastic HO kit from Dave Grandt at Grandt Line. It's called "No Problem Joes." I've built four of these for different projects. It's based on a prototype in the west but will fit in almost anywhere on a model railroad. All the plastic parts fit perfectly and it comes with good instructions. Perfect for the beginner.
I decorated the front room (with the double windows) with a bed, a night stand and two figures. It has a 12V grain of wheat lamp with an orange shade to light the bedroom.
