Home Owners

We all dream of our just right home – however you define it. Creating a home designed to support the lives and activities of those dwelling there can be an enormously rewarding undertaking. Architects have important contributions to make to this process.

Finding the right one is important. Choosing the right residential architect is even more critical.

I firmly believe that creating a new house for a client is a collaborative process between architect and client. I listen very closely and ask thoughtful questions to help me understand and identify your goals and priorities. Your answers will tell me about how you live, your aesthetic preferences, your budget, and your desired time frame. What you tell me will dictate the concepts, ideas, and possibilities that I’ll develop as we create the design concept for your remodel, addition, or new home.

Sustainability / Green Building

The most efficient way to design a sustainable / green project is by creating a design that works efficiently with the least amount of building space, which means that less space is required to be built and maintained, energy costs are lower, and less construction waste is produced during construction of the project.

These more efficient designs can have spaces that are designed for shared uses, reducing the impact on the site and can save the owner significant amounts of money. Design to respond to the site –attention to site orientation can make significant differences in the costs of heating, cooling, and lighting in a building.

Green buildings can be designed in any architectural styles and do not need to be designed in a style that happens to be popular this year and may not be next year. Higher insulation values, careful sealing of all exterior openings, more efficient mechanical systems, and products with non-toxic finishes are all examples of energy saving techniques that do not affect the exterior appearance of the building, yet can still be very cost effective.

For clients who are interested in remodeling or constructing an addition, I remind them of the saying that “The greenest building is the one already built”. Their existing home or building represents a sizable investment in energy required to originally construct that building. We can definitely improve the layout, appearance, and the energy efficiency. Tremendous energy and costs can be saved if the existing building can be improved, rather than tearing it all down and starting over. In some cases, that may be the best choice but the question “Is this building worth saving” certainly deserves to be considered.

Carl has an inherent sense of design elements, functionality, beauty, and precision. His designs are practical, yet innovative. He knows how to maximize a site and how to work positively and creatively within physical, economic, and regulatory constraints. His designs have what I refer to as the “Ahhhh” factor. They are intuitive and pleasing to the eye; they are interesting, but feel natural and “right”.

In 20 years of developing and building projects, the architect I have enjoyed working with the most has been Carl Colson. His plans are the most complete and extremely thorough. I use Carl exclusively for all of my projects, including a multi-family townhome project of 101 homes, 40 townhomes in Sedro Wooley, and 54 single-family detached homes in a mixed-use community.
Carl has always met the project deadlines, is very creative, and open minded about suggestions. Every one of my staff, including the field crews, has spoken very highly of Carl’s work – I have recommended Carl in the past and will continue to recommend him.

I have lived in a Cascade Cottages townhouse for the past year and a half, and I just love it. The entire space is thoughtfully designed and beautifully built. It’s clear Carl Colson understood what makes a beautiful home: spacious rooms, functional design and attention to detail.

Ann W.· Edmonds, WA

Carl’s designs are amazing and get the most for the client. He thinks about site design, exterior designs, interiors, curb appeal, and cost management. His exterior designs were very appealing, and his interiors were fantastic. I would strongly recommend Carl Colson for any of your architecture needs, from residential remodels to complex high-rise commercial developments and everything in between.

John Bissell· Edmonds, WA

Carl added a second story to our 1925 home on Queen Anne Hill. We liked the location but the bungalow was too small and dark. We envisioned a big bathroom and bedroom trying to capture as much light as possible. Carl designed the house to still look like a 1925 house outside and a light open space inside. Carl succeeded where I don’t think many architects would have. We love our house inside and out, and are still delighted with the light and space.

Eileen Enstrom – Edward Hart· Seattle, WA

We highly recommend Carl Colson! As homeowners, we truly appreciate Carl’s insight in the design process. We couldn’t be happier with the look and feel of what Carl created. The plans were incredibly detailed and accurate .and had absolutely no issues during the construction of the additions. Carl not only has an eye for the design of a project but he also has the practical building process knowledge that makes the construction practical saving time and material costs. We would strongly recommend Carl for any architectural project.
