Mason and son ROCKS! Dennis is, hands down, the best designer I have ever worked with. He has a keen eye for the site, a steady hand at the drawing board, and a gift for understanding his clients almost to the point of telepathy. Beyond this insight, he has the good sense to respect, and to capitalize upon, the experience and ability of the tradesmen, craftspeople and artisans he engages to manifest his designs. Further, having worked with him on and off since 1989, I can say without reservation that Dennis Mason is the single most even-tempered person I have ever met. If you want a TRULY custom-built home, talk to Dennis.
