Kind Words About Us

Bill Patterson was the easiest and kindest to work with. Upon a still foggy dream of building an ADU, Bill effectively brought our ideas into place with multiple sketches of possibilities, research for codes, setbacks, marking our lot out, determining electrical options, and laying out turn key price options for us, everything included. Bill returned our phone calls same day, and came to our house to visit right away. His timeliness, professionalism, and designing was spot on. Our ADU dream, with the proper financing in place, wins Bill Pattterson’s talent!
