I had a consultation with Sustainable Design Build regarding a basement project, and even though the project ended up being too small for the type of work they typically take on, Mike McCarty still spent a tremendous amount of time helping me. He patiently answered my questions, shared his knowledge, and provided multiple referrals for mold remediation, testing, and construction professionals who could better fit my needs. At no point did I feel rushed or dismissed. In fact, he went above and beyond to help me move forward with my project even though there was no benefit to his company. That level of honesty, professionalism, and genuine willingness to help is rare. It was clear that Mike truly cared about helping me find the right path rather than simply trying to sell me something. I am incredibly grateful for the time, guidance, and referrals he provided. If my project ever grows into something that fits SDB's scope, they will absolutely be the first company I call. Thank you again, Mike!

My wife and I had a great experience with SDB, specifically with Mike McCarty and Trevor. This is such an intimidating and cumbersome experience but Mike was incredibly patient and thorough and made the entire engagement enjoyable.

I highly recommend Sustainable Design Build for any future design needs you might have! They were wonderful to work with, and their attention to detail was second to none! Designers Megan and Mallen were wonderful to work with along with the rest of the staff we encountered. I will definitely use Sustainable Design Build for my future projects!

I recently reached out for an estimate on a home addition, and I couldn’t be more impressed with the professionalism from start to finish. They showed up on time, walked me through every detail of the project, and answered all my questions clearly. It’s rare to find a builder in Denver who combines great communication, transparency, and true craftsmanship, but these guys do exactly that. If you’re looking for a trustworthy team for a home addition or any major project, I highly recommend them — top-notch experience all around.

We reached out to Sustainable Design build while looking at different general contractors for our home in Denver. Being in the very early stages, we weren't sure about which direction to go with our home whether it would be a pop top and building a home addition or remodeling our whole house. From the very beginning, the team was straightforward and transparent about what was realistic for our house and budget. They were educated and knowledgeable about Denver building codes, we even learned we could build an ADU if we wanted to. Mike was especially helpful, laying out what our home actually could be within the budget we set, which was nice comparatively to some other companies we talked with who just seemed ready to sign us on without much of an idea. SDB's responsiveness was the best part, from the start all of their team was involved. They even have in-house architects and interior designers presenting plans on paper for us to look at. They made sure we knew all the possibilities for our home and made sure we understood what every step would be like before committing to anything. Working with SDB was confidence inspiring for such a big undertaking our family was exploring.

Common Questions about Sustainable Design Build and our Full-Service Design Build Process

What is a Full-Service Design-Build Firm?

A Full Service Design-Build Firm is an organization that offers both the design and construction services required for building residential or commercial projects. The Design services offered include architectural, structural, soil, and other required disciplines. All of those services will be managed and run by SDB as the project lead and main point of contact. SDB will also schedule, manage, and perform all construction trades needed to complete the project. The benefit of this is an all-in-one approach allows SDB to leverage their experience of construction through all phases of a project and produce efficiencies in a client’s budget, schedule, and finished product.

The difference SDB makes compared to others is our approach to project design and estimation. We operate with first a design phase that lays out a design tailored to your goals, a detailed and complete scope of work, and a fixed cost for the entire project.

This type of service is especially valuable to clients who are seeking larger construction projects such as home additions, Accessory Dwelling Units (ADUs), or custom home construction. SDB provides turn-key design and construction services to clients looking to build the home of their dreams.

Is Design-Build more expensive than a General Contractor?

No, the design-build process is laid out to produce efficiencies where traditional construction methods lack. This maximizes the value a client receives throughout the entirety of the design and build construction process. By being a Full-Service design-build firm, it makes SDB keenly equipped to provide the most accurate pricing and efficient construction practices. Efficiency in construction gets you back into your home sooner. 

What are the BENEFITS of the Design-Build Process?

The design-build process is a unifying method of construction that is led under a single point of contact, much like a general contractor. However, the design-build company offers much more by being a part of the design process of a project. This lends conscious decisions in the design of the project which will help align client goals.

Communication

Single point of contact. SDB communicates with all trades and disciplines required for construction; architectural, structural, civil, soils, City Officials, Carpenters, etc., so you don’t have to!

Faster Project Completion

With SDB’s experience, industry knowledge, unique design build process, and team approach your construction project will be on the fast track to completion. 

What is The SDB Design-Build Process?

The design-build process is a streamlined construction method where architects and designers collaborate directly with Sustainable Design Build who will manage all the construction of your project. By acting as the single point of contact SDB will guide your project through three phases.
