Room Addition & ADU Construction Denver

Expand Your Home, Enhance Your Life

Transform Your Living Experience with a Custom Home Addition

For those looking to create a new kind of living space or generate income through rental, a new custom accessory dwelling unit is the answer!

Our Denver construction company focuses on tailoring every ADU project to the customer’s needs, blending high-end design quality with function.

Why Denver Homeowners Are Choosing to Expand Instead of Move

Home additions can be a more cost-effective solution than moving to a larger home.

In the Denver metro area modern real estate market, homeowners are left wondering whether to expand their current space or endure the stress of a move.

Home additions can effectively provide more space as families grow.

Unlock More Space and Comfort for Your Growing Family

As your family grows, your home can feel smaller.

Rather than uprooting, you can choose to evolve your current space.

This can provide you with an additional bedroom, a mother-in-law suite, a new play area for the little ones, or even help you optimize existing square footage with basement remodeling.

When your design-build process is thoughtfully done, you don’t have to make a sacrifice to sell the house and relocate.

Increase Your Property Value with Strategic Upgrades

Strategic ADUs don’t just provide more room; they deliver a high return on investment.

This can significantly boost your home’s long-term market value.

By increasing the home’s square footage, your property suddenly stands out among the rest in Denver’s evolving landscape.

Specialized ADU Construction that Denver Can Trust

Since late 2024, Denver has permitted ADUs in more than 70% of residential areas.

With Verified Builders, we can easily navigate citywide zoning laws to design and build the highest-quality ADUs in Denver.

We are here to streamline the complex permitting process, ensuring your newest room addition or expansion offers all of the comforts of home, no matter what the intended use.

What is an Accessory Dwelling Unit, and Is It Right for You?

ADUs can truly enhance the value of a property and generate rental income for homeowners.

But assessing your home’s square footage and how you intend to use the extra space is essential to determining which type of expansion is right for your home.

ADUs in Denver typically require fewer resources to build and much less energy to heat and cool due to their smaller size, contributing to environmental efficiency.

Shared utilities for ADUs (water, sewer, electric) are preferred when feasible in Denver, though new water licenses may be required.

Detached ADUs: The Perfect Guest Suite or Rental Income Source

A detached ADU is a great option for homeowners hoping to maximize the space on their property.

This option provides the following benefits:

  • Financial independence to generate a monthly income for long or short-term rentals.
  • Additional layers of privacy if you are looking to separate your work from your home, or provide an extra space for guests.
  • Independent living options for aging parents, providing all the amenities of a standalone home.

Attached ADUs: Seamless Extensions for Multigenerational Living

The attached ADU options are simply extensions of the current living space.

The design of home additions should match the existing home’s architectural style and materials for a seamless look.

These are great for the following:

  • Flexibility in your current space with a garage conversion or lateral addition.
  • Utility efficiency offers a faster process and simplified costs all in one space.
  • Integrate accessibility throughout the home, offering a space that can be used by children, caregivers, or for work!

Home Additions: Build Up, Not Out

A popular home addition is a pop-top addition (AKA second-story additions), which can maximize a home’s footprint.

Vertical expansions allow many homeowners to increase their square footage and enjoy more living space.

Maximize Your Lot Potential with Additional Space

Opting for a story addition is ideal when you live in places like Wash Park or Sloan’s Lake.

When outdoor space is limited, there are generally requirements that prevent you from expanding outward.

Pro Tip: Attic conversions are a common type of home addition that can provide additional living space.

Is a Room Addition the Right Solution for Your Single-Story Home?

Deciding on a room addition requires thoughtful design.

It is a significant undertaking, but it can reveal more spacious living and rewarding results.

Start with the following before making your decision:

Structural Considerations for Second-Story Expansions

Remodeling to add a story to your home requires a full-scale design and engineering evaluation.

You will need to ensure that there are load-bearing walls present to support the new addition.

Luckily, our team manages complexities to ensure every project meets local safety codes!

Custom Room Additions & Bump Outs for Multi-Generational Living

Our team helps residents with a wide range of home addition projects.

This can include fully custom room additions and bump-outs when you aren’t in the market for a full house remodeling project.

Your project manager supports you through expanding a cramped kitchen or even adding a new sunroom.

We’ll be there every step of the way to achieve your dream home.

Sunrooms and Enclosed Patios for Year-Round Enjoyment

Soaking up the sun is something Denverites are used to, being a mile closer to the sun than the rest of the country.

But not everyone has access to a premium sunroom!

By using energy-efficient glass and climate control, Verified Builders can create a new sanctuary for your household.

Architectural Design and Lasting Value Planning

We allow clients to interact with options and every square foot of the new addition.
