Sam and his team did an amazing job with a complete renovation of our late 80's PNW contemporary. We gutted the top 3 floors which included all the main entertaining areas and bedrooms, as well as adding a bedroom with en suite bath. It was a pretty significant project with lots of moving pieces, but Sam kept everything moving forward and on track. We were so pleased with the overall result that we had the team back a year later to redo our rooftop terrace with a new glass railing!!Read More
