"At every step along the way they were thorough and professional. The estimator provided a very detailed scope and quote and patiently answered my questions. The installation crew was quick, efficient, friendly, and were so meticulous with their prep that up you couldn't even tell they were here after they left. I also appreciated the "after-photos" they sent me, it looks great!"

Thoughtful design for residential and small commercial projects in the Pacific Northwest.

"Lisa is a genius! With creativity and precision, she maximized every nook and cranny of our tiny 1906 cottage and brought it into the 21st century, while maintaining its original charm and character. Our "new" home is so much more functional now, and a delight to live and work in. Lisa took the lead on our projects (kitchen, bathroom, basement), but Adam is equally savvy. Both are fantastic listeners, brainstormers, collaborators, total professionals and all-around lovely human beings. We highly recommend Christie Architecture, and look forward to working with them again in the future!"

Baker & Son Construction has more than 45 years extensive experience in every aspect of building, developing, remodeling and reconstruction. We will get your job done on time and on budget. Our team has the highest standards and stand behind every detail in the construction process. Client trust, attention to detail and a commitment to excellence are our highest goals, and our customers have proved their trust over and over by giving us their return business and recommending us to their friends and family.

"The project was essentially a remodel of a circa 1950's beach cabin with a small addition. We chose Baker and Son on the recommendation of our neighbor who had used them to build a detached garage. Our plans were relatively simple at first: build the addition, expand the kitchen, build a new bathroom and create a new entry. As work was underway, it became clear through the advice of Baker and Son that our kitchen was too big and out of scale for the cabin. We ended up eliminating some walls and opening up the cabin in such a way that created one large room but still a separate kitchen, dining and living. It was a huge improvement to the original design. In addition to the interior work, Baker and Son completely overhauled the exterior which included new windows and siding. New structural headers were required because they didn't exist. Also, since the cabin is post and pier construction, they leveled and strengthen the existing structure. Work included new skirting as well. Their attention to detail was very impressive. They are masters at creative problem solving, patient, responsive and positive. They have a very strong sense of design. We were never pressured into quick decisions. The contract arrangement for our project was essentially time and material because formulating a bid on an old cabin remodel would involve too many unknowns. We agreed to a fair hourly rate and all material and subcontracted work we paid directly with no additional overhead or fee. This saved us money. Since we lived out of town, Baker and Son were so well connected with various vendors and subcontractors, it simplified making arrangements. Now that our project is complete, we are so excited about the end result! We would highly recommend using Baker and Son Construction for any project."
