Why Arvada Homeowners Choose Christie's

Because the Home You Love
Should Have Room for What Comes Next

For more than 25 years, Christie’s has helped Arvada homeowners create the space their lives have been asking for. A first-floor addition that gives a growing family room to spread out. A private ADU where parents can stay close while still having a place of their own. Extra square footage that solves the daily frustration of a home that simply feels too small. The goal is always the same: make staying feel better than leaving.

At Christie’s Design/Build Remodeling, we start by understanding why more space matters to you in the first place. We look at where your home feels tight, how your family uses each room, and what would make the years ahead easier. From established ranch homes near Olde Town to larger properties west of Wadsworth and newer neighborhoods toward Indiana Street, we plan additions and ADUs around the home you already have, the property it sits on, and the life you want to keep building there.

What Makes Additions & ADUs Different In Arvada

More Space Has to Feel
Like It Has Always Belonged There

Adding onto an Arvada home means working with what is already there, from the structure beneath it to the character that made you love the house in the first place. Older ranches near Ralston Creek can bring foundation, roofline, and mechanical considerations, while newer homes farther west may call for careful planning around lot size, setbacks, and neighborhood design. At Christie’s Design/Build Remodeling, we look at the entire home before deciding where new space should go. The goal is an addition or ADU that improves how you live without losing the proportions, flow, or familiar feeling of the home you wanted to stay in.

.01

Arvada Homes Come in Many Forms

Mid-century ranches, split-levels, and newer homes each create different opportunities for added space. We study the existing structure and property first so the addition begins in the right place.

.02

The Existing Structure Sets the Rules

Older Arvada homes can have unique foundations, rooflines, and load paths. Understanding those conditions early helps us create an addition that connects naturally and performs as one home.

.03

Older Systems May Need Attention

Opening walls can reveal electrical, plumbing, or HVAC systems that need updating. Identifying those needs during planning helps prevent surprises once construction is underway.

.04

Colorado Weather Shapes the Details

Strong sun, temperature swings, snow, and dry winters all influence exterior materials and insulation. We plan those details carefully so the new space feels comfortable and holds up over time.

Arvada, CO Neighborhoods

More Room Without Leaving
the Arvada You Love

Arvada is filled with homes people have already built a life around, which is exactly why an addition or ADU can mean so much more than gaining square footage. Some families need another bedroom before the kids get older. Others are making room for a parent who wants independence without being far away. Sometimes the kitchen, living room, or primary suite simply needs the space the original floor plan never provided. Across Arvada, the right solution depends heavily on the home and property itself, from established neighborhoods near the center of town to newer communities stretching toward the foothills. Local zoning also considers factors such as building placement, lot dimensions, and accessory structures, making thoughtful planning especially important before a design takes shape. We approach each project by asking what would make staying in this home feel easier, more comfortable, and right for the years still ahead.

Meadowglen

Give a Familiar Home Room to Breathe Again

Meadowglen has the kind of established character that makes leaving difficult. When a home starts to feel tight, an addition can create the space a family needs without giving up the neighborhood they already love. That may mean a larger kitchen, a new primary suite, or an ADU for a parent or adult child who needs privacy while staying close. We look carefully at the existing structure, rooflines, circulation, and outdoor space so the new square footage feels like a natural extension of the home.

Meadows At Westwoods

Expand the Home Without Losing What Makes It Special

Homes in the Meadows at Westwoods often already have generous layouts, attractive surroundings, and a strong connection to the outdoors. Here, an addition may be less about fixing a small house and more about creating the space that is still missing, such as a larger primary suite, dedicated office, expanded kitchen, or private family accommodations. We plan around the property’s existing architecture, views, and outdoor areas so the new space adds comfort without taking away from what made the home special in the first place.

Village Of Five Parks

Make More Space Feel Completely at Home

Homes in Village of Five Parks may already feel modern and open, but family needs can still outgrow the original floor plan. An addition can create a guest suite, larger family room, office, or extra bedroom, while an ADU can give extended family a private place nearby. Because the neighborhood has a cohesive architectural feel, every detail matters. We consider rooflines, exterior materials, proportions, and interior flow so the added space feels intentional and fully connected to the home around it.

Leyden Rock

Create Room for the Life Still Ahead

Even newer homes in Leyden Rock can start to feel different as life changes. A permanent home office, growing children, longer family visits, or aging parents can quickly create the need for more flexible space. An addition or ADU can solve those needs without giving up the neighborhood or setting homeowners chose. We plan around the property’s grade, outdoor living areas, existing architecture, and views so the new space feels integrated from the start and supports the way the household wants to live in the years ahead.

Candelas

Grow Into the Home You Planned to Keep

Candelas homeowners often choose the area with the expectation of staying long term, which makes an addition or ADU a natural solution when the house needs to evolve. A growing family may need another bedroom, a larger gathering space, or a dedicated office. Others may want a private place for parents or adult children. Because these homes are newer, additions need to feel especially cohesive. We match proportions, materials, windows, and rooflines carefully so the added space feels like part of the original home rather than a later addition.

Our Arvada Additions & ADU Process

From First Idea to Finished Space

Adding an addition or ADU in Arvada comes with questions that are specific to both the property and the home already standing. An older ranch near Olde Town may need a completely different approach than a newer home in Candelas. Our process guides each project through site evaluation, design, permitting, construction, utility coordination, and final completion, keeping every phase clear while making sure the new space feels fully connected to the home you already love.

.01

Site & Structure Review

Every Arvada addition or ADU begins with understanding the property. We evaluate the lot, existing structure, setbacks, access, and how your household currently uses the home. We also look closely at foundations, rooflines, and load-bearing conditions so we know how new square footage can connect safely and naturally. Starting here gives the project a realistic foundation before design decisions begin.

.02

Goals & Design Direction

Before plans take shape, we talk through what the new space needs to change for your family. That may mean more privacy, another bedroom, a larger gathering area, or an independent ADU for someone you want nearby. We consider circulation, storage, access, and how each new room should relate to the existing Arvada home so the design feels personal and purposeful.

.03

Detailed Project Planning

Once the direction is clear, we work through the details that turn the idea into a buildable plan. Foundation work, framing, insulation, utilities, interior layouts, and material selections are coordinated around your property and existing home. This stage helps everyone understand how the addition or ADU will come together before construction begins, reducing unnecessary changes once work is underway.

.04

Permits & Trade Coordination

Before construction begins, we coordinate the permits, approvals, inspections, and trade scheduling required for the Arvada project. We manage filing, review timelines, material lead times, and the order each specialty trade needs to arrive. Keeping those pieces organized early helps prevent avoidable delays and gives you one clear point of communication instead of managing contractors, suppliers, and inspectors yourself.

.05

Construction & Communication

With approvals in place, your new space begins taking shape. Framing, insulation, mechanical work, drywall, flooring, cabinetry, and finishes move forward under one coordinated team. Whether we are building a primary suite, family room, office, or detached ADU, we keep you informed throughout construction while protecting the quality, organization, and connection between the new space and your existing home.

.06

Final Review & Completion

As construction wraps up, we walk the completed addition or ADU with you and review the details together. We confirm finishes, address remaining items, and make sure the new space connects comfortably to the rest of the home. The goal is a finished project that feels settled, intentional, and ready to become part of your family’s normal rhythm from the moment you move into it.

What Arvada Homeowners Want From Their Addition or ADU

More Room for the
Life You’re Building

Addition and ADU projects in Arvada are rarely about adding square footage for the sake of having more of it. Most homeowners are trying to solve something they feel every day: a kitchen that gets crowded too quickly, nowhere for visiting family to stay comfortably, kids who need more room as they get older, or parents who would be better close by without giving up their independence. Older homes near Olde Town and along established corridors can require more creative planning, while newer neighborhoods may offer different opportunities for additions, bonus spaces, or detached ADUs. What Arvada homeowners tend to want most is space that feels useful, connected, and completely natural to the home they already love.

More Room For Family

Space That Finally Fits

In established Arvada neighborhoods like Allendale and Westwoods, many homes were built for smaller households. A thoughtful addition can open the main living area, create a larger primary suite, or give kids and visiting family space of their own without leaving the home everyone already loves.

Flexible Floor Plans

Room to Grow Into

Some Arvada homes still carry layouts that worked decades ago but feel restrictive today. Reworking the connection between old and new space can create better flow, fewer awkward transitions, and rooms that adapt as family needs change.

Smart Storage

A Place for Everything

Larger Arvada lots can create opportunities for additions that solve more than square footage. Built-in storage, mudrooms, laundry space, and thoughtfully planned closets help the new area feel calmer, more organized, and easier to live in every day.

Private Family Space

Close, With Room Apart

For homeowners near Ralston Creek and Lake Arbor, an ADU or private suite can make multigenerational living feel comfortable instead of crowded. Separate entrances, bedrooms, baths, and living areas give family members independence while keeping everyone close.

Durable Finishes

Made for Colorado Living

Arvada additions need to handle snow, strong sun, muddy shoes, pets, and constant seasonal changes. Durable flooring, exterior materials, and practical finishes help the new space stay beautiful while standing up to the way Colorado families actually use their homes.

What To Consider When Building An Addition or ADU In Arvada

Plan for the Space Your
Life Actually Needs

An addition or ADU can completely change how an Arvada home supports the people living there, but the best projects begin with more than a square-footage goal. An older ranch near Ralston Valley may offer opportunities a newer home farther west does not, while lot size, existing structure, access, and utility placement can all shape what is practical. Before design begins, it helps to understand what the new space needs to solve, how it should connect to the home, and what will make it feel right years from now.

What Does Your Family Need Most?

Start with the reason you want more room. A growing family may need bedrooms and gathering space, while aging parents may need privacy and accessibility. Knowing what should feel easier once the project is finished helps determine whether an attached addition, private suite, or ADU makes the most sense.

Every Arvada lot creates different opportunities. The home’s placement, available yard space, existing rooflines, access, and surrounding outdoor areas all influence where new square footage can comfortably go. Planning around those conditions early helps the addition feel connected instead of forced onto the property.

Adding living space often means extending electrical, plumbing, heating, cooling, and other systems already serving the home. Older Arvada properties may require more coordination before new rooms can be added comfortably. Evaluating those systems early gives the project a clearer path and helps reduce unexpected changes during construction.

The transition between the original home and the addition matters just as much as the new rooms themselves. Flooring, ceiling heights, windows, exterior materials, circulation, and natural light all influence whether the space feels seamless. The goal is to walk through the finished home without feeling where the old house ends and the addition begins.

Arvada Addition & ADU Frequently Asked Questions

The Questions Behind
Making More Room Feel Right

Adding onto a home you already love can bring a completely different set of questions than starting somewhere new. In Arvada, the answers can depend on everything from the age and structure of the house to lot dimensions, zoning, utilities, and whether the new space will be attached or independent. The City also has specific permitting and development requirements for additions and ADUs. These are some of the questions we hear from homeowners who want more room without giving up the place that already feels like home.

Can I build an ADU on my Arvada property?

In many cases, yes. Arvada allows ADUs in connection with single-family homes, but the design still has to meet the development standards that apply to the specific property. Lot size, zoning, placement, and whether the ADU is inside the home, attached, or detached can all shape what is possible. We start by understanding the property before designing around an idea that may not fit the site.
Arvada ties allowable ADU size to factors including the existing home’s living area and the size of the lot. Newly constructed attached ADUs generally cannot exceed 40% of the primary home’s living space, and additional maximum floor-area limits can apply based on lot size. ADUs created within the existing home, such as a basement conversion, are handled somewhat differently.
Potentially. Arvada recognizes ADUs created within the footprint of an existing home, including basement spaces. These projects still need to satisfy building, safety, access, utility, and permitting requirements, so having unused downstairs square footage does not automatically mean it is ready to become a separate residence. The opportunity is often there, but the existing conditions need to be evaluated first.
Residential additions require permitting through the City of Arvada, and plans may need to address the structure, property layout, electrical, plumbing, mechanical work, and other elements of the project. The City requires permits for attached and detached structures, including residential additions, before construction begins.
Absolutely, but older homes deserve a closer look before walls start moving. Existing foundations, framing, rooflines, electrical service, plumbing, and HVAC can influence how an addition is designed and connected. That early evaluation is especially valuable in Arvada’s established neighborhoods because it lets the new space respond to the house that is actually there instead of forcing a newer plan onto an older structure.
An ADU can provide opportunities beyond family living, but the intended use matters. If you plan to operate the space as a short-term rental, Arvada requires both a short-term rental license and a business license. Rental plans are worth discussing early so the layout, access, privacy, and permitting strategy support how you actually expect to use the space.
Not necessarily. How plumbing, electrical, heating, cooling, sewer, and water are handled depends on what you are building and how independent the new space needs to be. ADU projects can also involve additional utility requirements and fees, including potential sewer and water considerations. We account for those connections during planning so they become part of the design rather than an expensive surprise later.
That starts long before choosing finishes. We look at rooflines, window proportions, ceiling heights, exterior materials, interior circulation, and where the new rooms meet the existing floor plan. The goal is for an Arvada addition to feel settled into the house, so once your family begins living in it, the new space feels less like something that was added and more like something the home was always missing.
