Sustainable Design Build (SDB) is a Denver-based design-build firm specializing in residential construction, accessory dwelling units, home additions, remodels, and custom homes. Founded in 2017, the company originally focused on multi-family construction projects and townhome developments throughout Denver before expanding into full-service residential design and construction for individual homeowners.

Today, SDB is recognized as an award-winning homebuilder and has earned a reputation for delivering integrated design-build solutions that streamline the entire construction process under one contract.

A Fully Integrated Design-Build Approach

Unlike traditional construction models where homeowners separately hire architects, designers, and contractors, Sustainable Design Build operates under a unified design-build structure. This creates a single point of accountability from the earliest concept discussions through final construction completion.

The advantage of this approach lies in early collaboration between:

Architects
Designers
Engineers
Project managers
Construction teams

By integrating these disciplines from the beginning, SDB is able to improve communication, reduce delays, minimize costly change orders, and maintain tighter budget control throughout the project lifecycle.

Clients work directly with one team instead of coordinating multiple vendors independently, simplifying both communication and project management.

The SDB Three-Phase Process

Sustainable Design Build structures projects into three clearly defined stages:

Concept Phase

The process begins with discovery meetings focused on understanding the homeowner’s goals, property conditions, budget, and long-term plans. During this phase, the team develops:

Concept plans
Floor plans
Initial project scope
Preliminary feasibility analysis
Fixed project pricing guidance

Design Phase

Once the project direction is established, SDB manages the technical and permitting aspects of development, including:

Permit submissions
Structural engineering
Energy compliance engineering
Site surveys
Soil testing
City coordination and approvals

This phase is designed to resolve potential construction challenges before breaking ground.

Construction Phase

After approvals are secured, SDB oversees the complete build process, including:

Construction scheduling
Trade coordination
City inspections
Engineering inspections
Final punch list completion
Workmanship warranty support

Their integrated workflow helps maintain consistency between design intent and field execution.

Specialized ADU Design and Construction

Accessory dwelling units are one of Sustainable Design Build’s primary specialties. As an experienced ADU contractor and detached ADU builder, the company works with homeowners across Denver and surrounding metro areas to create functional, efficient secondary living spaces tailored to both the property and the homeowner’s goals.

Their ADU services include:

Detached ADUs
Backyard cottages
Granny flats
Garage conversions
In-law suites
Junior ADUs (JADUs)
Attached accessory dwelling units

Thoughtful ADU Floor Plan Design

Designing an ADU requires careful attention to how space functions on a day-to-day basis. SDB approaches each project with a strong focus on usability, natural flow, and spatial efficiency.

Their design team evaluates:

Property layout
Access points
Privacy concerns
Natural light exposure
Existing lot constraints
Zoning limitations

Floor plans are carefully arranged to maximize openness and comfort, even within compact footprints. Storage solutions, kitchen functionality, furniture layouts, ceiling heights, and window placement are all strategically considered during the design process.

The result is an ADU that feels practical, comfortable, and visually connected to the existing property.

Navigating Denver Zoning and Permitting

One of the most challenging aspects of ADU construction in Denver is understanding zoning eligibility and navigating permitting requirements.

Sustainable Design Build has extensive experience working within Denver’s zoning system and understands the complexities involved in ADU approvals across a wide range of residential zoning districts.

The company assists homeowners with:

Zoning verification
Feasibility analysis
Setback requirements
Lot coverage limitations
Permit coordination
City planning approvals

Their familiarity with Denver Community Planning and Development processes helps streamline projects and reduce unnecessary delays during permitting.

Additional Residential Construction Services

Beyond their work as an accessory dwelling unit builder, Sustainable Design Build also provides a broader range of residential construction services, including:

Whole Home Remodels

Comprehensive remodeling projects involving design, architecture, interior selections, permitting, and construction management.

Home Additions

Custom additions designed to expand existing homes while blending naturally with the original structure.

Custom Homes

Turn-key custom home design and construction services from initial planning through move-in completion.

Built Around Efficiency and Collaboration

SDB believes the design-build model creates efficiencies that traditional construction methods often lack. By keeping design, engineering, budgeting, and construction aligned from the beginning, they aim to deliver projects with greater transparency, faster timelines, and stronger cost predictability.

Whether a homeowner is planning a detached backyard cottage, a garage conversion, a full home remodel, or a custom home build, Sustainable Design Build offers an integrated process designed to simplify construction while delivering tailored results built around the client’s long-term goals.
