Scratchbuilding an N-scale house, part 1

This is the first of a 4-part series in which I document my first attempt at scratchbuilding in a new scale. No I haven't abandoned my HO-scale layout in favor of a new scale. This is a professional structure building contract - hopefully the start of a new career. It's certainly easier and quicker building a house in N-scale than in 12"=1ft scale.

Correction: The random stone foundation is "N-scale Architect", not "JTT".
