THE RIGHT ADDITION
It Should Feel
Like It Was
Always There.
That means understanding the architecture, structure, proportions, materials, and character of the existing home before deciding what to change. It also means understanding how you actually live — and designing a solution that fits both the house and your future.
At Crimson, we approach every addition as part of the home, not a separate structure attached to it. We study what exists, address what isn’t working, and design the new space to feel natural, intentional, and enduring.

WHAT CAN CHANGE
More Space. A Better Way to Live.
01
Gain the space you need without leaving the neighborhood you love. Second-story additions create new bedrooms, bathrooms and living areas while preserving your outdoor space.
02
Create the additional room your household needs for everyday life, entertaining, working from home, or accommodating a changing family.
03
A kitchen addition can transform how you cook, gather and live — with more space, better flow and a stronger connection to the rest of your home.
04
An addition can do more than add space. It can improve circulation, bring in more natural light and create a home that works better for the way you actually live.
WHY CRIMSON
Design What You Build.
Build What You Design.
At Crimson, the architect, designer and builder are part of the same team. That means the person designing your addition understands how it will be built, what it will cost, and what it will take to get through permitting and code. You get one team, one contract and one accountable party from first sketch to final punch list.
INTEGRATED TEAM
Architecture, design and construction under one roof.
REAL BUDGETS
The design is developed with cost in mind from the beginning.
EXISTING HOME EXPERTISE
We evaluate the actual conditions of your property, not just the drawings.
CONSTRUCTION DOCUMENTS
Full permit sets, engineering and jurisdiction-specific requirements.
CLEAR COMMUNICATION
You’ll always know what’s happening, what’s next, and what it costs.
“A beautiful drawing that can’t be built for the money the client has isn’t design. It’s a sales tool.”

"Glenn and the Crimson team did a complete remodel of the top floor of our home, including a complete reconfiguration of the bathroom. They are pure professionals. They know all the ins and outs of everything. For us, Glenn did the architectural work, and him and the team did all the construction work. Our house turned out amazing, and we would highly recommend him. If we ever need to do significant work on the home again, we will use him and the team at Crimson."

"Glenn and the team of professionals at Crimson Design did an impeccable job creating our state of the art video and photography studio. From the technical needs - like a 20' backdrop - to the client facing details - like the climate controlled, glass-walled conference room, Crimson had the expertise to get the job done and done well. Every person on his crew was conscientious and experienced, assuring no detail was overlooked. It was a relief to work with a contractor I could trust and talk freely with throughout the entire process. They even stayed within budget! I will absolutely be calling Glenn for my next project."

"After years of contemplating a first-floor remodel of our split-level mid-century modern home, we chose Crimson Design & Construction to bring our vision to life—and they delivered beyond expectations. From the beginning, we were impressed by Glenn’s architectural background and his ability to truly listen. He helped us reimagine our space, showing how removing walls and expanding the kitchen would enhance not just the kitchen itself, but also our living, dining, entryway, and outdoor areas. The remodel was extensive: structural wall removal, load-bearing beam installation, sliding doors and windows, hardwood floor refinishing, door replacements, electrical upgrades (including burying overhead lines), a complete kitchen renovation, and replacing our old deck with a maintenance-free composite one—all while we remained in the home. Glenn, along with designer Heidi, project manager Alex, and the entire construction team, delivered outstanding results while maintaining the integrity and style of our home. The craftsmanship, attention to detail, and overall quality exceeded our expectations. The team was professional, courteous, clean, and deeply committed to their work. Though the project took a bit longer than expected, it stayed on budget—and the results speak for themselves. We love our new kitchen, deck, and expanded living space - what a transformation! We highly recommend Crimson Design & Construction."
