CENTREVILLE, Md. — The two-story home Vicco von Voss built for his family here is more like a giant piece of custom-made furniture than a house.

For starters, there are no nails in the frame; it’s held together entirely with wooden pegs in an impressive display of mortise-and-tenon joinery. And every plank and beam was milled on site by hand, most from fallen trees collected nearby and salvaged.

So it will come as no surprise that it took a little longer to build than the average house. In fact, after 10 years, it’s still a work in progress.
