      I hired Matt and his team to help frame my new dream home. When my foundation crew skipped town and left me in a bind, Matt jumped in and saved the day. In an area where construction seems more like the wild west where there is no quality control or repercussions for people who have no business in construction, Matt is a rare find. He is trustworthy, honest, and hard-working, qualities that are definitely hard to come by in construction in Seattle these days. If you are in need of work to be done, I would not hesitate to call Matt and his crew.

      No. 7 Development is a first class company. Matt is a solid guy that sticks to his word. We had Matt and his crew do a build out in our office location and he got done earlier than planned and on budget. Two things that rarely happen these days. Their work is top of the line and I was really impressed with the final product. I would recommend No. 7 Development to anybody looking for a great builder.
