ADUS & COACH HOUSES
A Separate Space,
Designed Around Your Plans.
An ADU or coach house can give your property significantly more flexibility without giving up the home and neighborhood you already love.
Whether you need space for family, a private workspace, guests, or another long-term use, the design has to work with the property, the existing home, and the requirements of your municipality.
Crimson brings architecture, interior design, documentation, permitting, and construction together under one roof, giving you one team from the first idea through completion.

THE RIGHT BEGINNING
Before we draw the first line, we want to understand what you need the space to accomplish.
Who will use it? How will they enter? How should it relate to the existing house? What needs to happen inside? And how should the new space fit into the property?
Those questions shape the design from the beginning.
The goal is not simply to add another structure to your property.
It is to create a space that feels intentional, works for its purpose, and makes sense alongside the home that is already there.
YOUR NEEDS
YOUR PROPERTY
YOUR FUTURE
A SPACE THAT MAKES SENSE.
THE CRIMSON DIFFERENCE
ONE TEAM.
FROM FIRST SKETCH
TO FINAL DETAIL.
An ADU becomes much more complicated when the people designing it are separate from the people building it.
At Crimson, everything works together.
Architecture, interior design, construction documentation, permitting, selections, and construction are connected from the beginning.
The person making the design decisions understands how the project will be built. The construction team understands why it was designed that way. And you have one team responsible for carrying the project forward.
ARCHITECTURE
Designed around your property.
INTERIOR DESIGN
A space designed for how it will be used.
CONSTRUCTION
Built with the design in mind.
ONE VISION. ONE PROCESS. ONE ACCOUNTABLE TEAM.
A MORE COHESIVE EXPERIENCE
When design and construction are connected, important decisions can be resolved earlier, the budget can stay tied to the design, and the finished space can feel like it was meant to be there.
BEFORE THE DESIGN
Know What’s
Possible Before
You Commit.
A great ADU starts with more than a good idea.
It starts with understanding the property, the intended use, the local requirements, and what the project will realistically involve.
We evaluate the existing conditions, zoning and permitting requirements, project scope, and investment before moving too far into design.
That clarity gives you a much better foundation for deciding whether and how to move forward.
01
THE PROPERTY
What can actually be built?
02
THE SCOPE
What does the home need to accomplish?
03
THE INVESTMENT
What level of investment makes sense?
04
THE PLAN
What needs to happen before construction begins?
YOUR PROPERTY
SETS THE STAGE.
An ADU or coach house has to work within the realities of the property.
We look at the existing home, available space, site conditions, zoning, setbacks, access, and the requirements of the municipality before developing the design.
The goal is to understand the opportunities and constraints early, rather than discovering them after the design is already underway.
SITE & EXISTING CONDITIONS
Understand what is actually there.
ZONING & REQUIREMENTS
Identify the rules that affect what can be built.
DESIGN OPPORTUNITIES
Find the best way to make the new space work with the property.
THE RESULT
A Clearer Path
Forward.
Understanding what is possible early allows for a more thoughtful design, a more realistic plan, and an ADU that makes sense for your property, your goals, and your investment.
FEWER SURPRISES
BUDGET & CERTAINTY
YOUR BUDGET
SHOULD HAVE
A PLAN BEHIND IT.
An ADU involves a lot of decisions.
The earlier those decisions are understood, the more control you have over the project.
We work through the scope, design, selections, documentation, permitting, and construction details so the investment is based on a defined project rather than a vague idea of what the finished space might cost.
The goal is straightforward.
Know what you are building. Know what you are investing. And have a clear plan for getting from one to the other.
A CLEARER PATH
From Ideas
to a Defined Plan.
Through early collaboration and detailed planning, we help you understand what is possible, establish the scope, align the design with your investment, and move forward with confidence.
01 UNDERSTAND
We evaluate the property, your goals, and what’s possible.
02 DEFINE
We establish the scope and develop a realistic investment range early in the process.
03 ALIGN
Design, selections and budget are considered together — so everything works as one.
04 MOVE FORWARD
With a clear plan, the path to construction is straightforward and the vision stays intact.
“Good design starts with understanding what the project needs to accomplish, and what it will realistically take to build.”

"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."
