"I was highly impressed with Systematic Engineering. Jennifer from their main office was very cordial and friendly in setting up my appointment. The company's President, Frank, arrived promptly and gave me a professional and thorough assessment of what I needed to know about my property. I will definitely call on them again!"

"It went well. I was pleased with the services that they provided and the plan that they came up with. I had no trouble submitting it to the city in order to obtain a permit. They were easy to work with, even coming out on Saturday or Sunday, or the evenings - whatever worked with my schedule. They are really friendly, helpful and easy to get along with. It was a great experience and I plan to go to them for some additional work that I am planning on doing."

"Chris Merrill was an absolute pleasure to work with. He was quick, responsive and incredibly helpful during a difficult situation while selling our home. My family and I cannot recommend his services and wealth of knowledge enough. Iâ m glad we had the opportunity to meet him and use his services!"

"I was really under the gun due to a prior Architectural firm not performing their duties per building plan codes. Not only were the plans incomplete but the City Plan Reviewer states(The Worst plans he’s ever seen) they will not make adjustments unless there is an additional charge for Thousands. Evaluation’s saved my clients and drew our project per code, along with Engineering in less time then they quoted. I highly recommended them, Especially Kirsten. You went above and beyond trying to coordinate this project. The staff was very professional and I will use them on all my projects. Sincerely, Frank B BCM Builders"

"Very professional and detail oriented."

Our sustainable architectural services support clients that are moved by their physical and emotional surroundings and seek affordable and honest expressions of their needs. The design process seeks to push the envelope of enclosure using the tools of practical forces to create aesthetic solutions suitable for today and tomorrow's inhabitants. Each project seeks dynamic interaction with its surroundings while expressing the integrity of its construction and materials. Generally, we strive to create simple, well-articulated forms that have an enduring meaning with materials that provide lasting value and low maintenance. Each integrated, holistic design solution seeks to unify the design interests of the client to find the sweetness of life merged with their changing lifestyle.\n\n We explore together spatial alignments that benefit from established site views and provide designs that benefit from natural day lighting, natural ventilation, grid-tied solar energy, geothermal heating or cooling systems and reuse of stored grey water for site irrigation. In this context, each project compliments the surrounding community's built expressions and adapts to the technological advances that are leading our culture towards an electronically connected network of balanced living and working conditions for family growth.\n\nOn this Web site you will discover innovative designed homes of remarkable strength, economy, and beauty, brought to life by a distinct architecture combined with a source of pollution-free energy. Each built-in biosphere, in gradual but constant motion, draws energy from the sun, and /or geothermal stability from the ground, creating a temperate climate that supports the primary living spaces. These holistic design expressions below represent some of the project solutions for our clients.\n\n
