This review is delayed by a few years, but better late than never. We hired Aaron Sitzmann Construction to build a 2-story sunroom where a deck and patio were both enclosed. These were two areas of our house that we had never used previously due to road noise you could hear on the outside of our home. The vision we had for this sunroom was exactly what Aaron built - the upstairs sunroom is breathtaking and the #1 focal point in our house, and we are now able to enoy our view unobstructed of Poo Poo Point, Issaquah Highlands, and other Issaquah areas. The attention to detail and craftsmanship is of the highest quality. Aaron worked with us side by side on every detail and from the windows, to the flooring, to the walls - everything is flawless. Lastly, the basement (patio) level sunroom has become a gym in our home and is also the perfect addition. All in all we couldn't love our house more thanks to our sunroom and can't recommend Aaron enough. We hope to one day do further updates on our house and would want to work with Aaron in a heartbeat.
