Home Addition in Owasso, Oklahoma
Cornerstone Homes & Properties brings over 20 years of custom home building experience to Owasso, OK. From new construction and whole-home renovations to additions and outdoor living spaces, our in-house design-and-build team delivers homes tailored to the Owasso lifestyle.
Owasso, Oklahoma has earned a well-deserved reputation as one of the best places to live in the entire state. Situated just north of Tulsa and approximately 15 miles west of our Claremore headquarters, Owasso is a community Cornerstone Homes & Properties knows intimately. Over the past two decades we have built custom homes, completed major renovations, and constructed additions for families throughout this thriving suburb. When you choose Cornerstone as your custom home builder in Owasso OK, you are partnering with a locally rooted team that understands the neighborhoods, soil conditions, building codes, and lifestyle expectations that make Owasso unique. Our proximity to the community — just a short drive west on Highway 20 from our Rogers County office — means we can be on your job site quickly and stay closely involved from the first shovel of dirt to the final walkthrough.
With a population that has surged past 40,000 residents, Owasso is no longer the small bedroom community it once was. It has evolved into a dynamic city with a robust retail and commercial corridor along US-169, a nationally recognized public school system, top-tier recreational amenities, and a housing market that continues to attract young professionals, growing families, and retirees alike. The city straddles both Tulsa County and Rogers County, giving homeowners access to a variety of lot sizes and zoning options. Whether you are looking at an established subdivision near downtown Owasso or a newer development farther north along 96th Street, Cornerstone can help you navigate the permitting landscape and design a home that fits both the lot and your long-term goals. Our experience with home construction in Owasso Oklahoma spans single-story ranches, two-story traditional plans, modern farmhouses, and everything in between.
Education is one of the primary reasons families choose Owasso, and the Owasso Public Schools district consistently ranks among the top school systems in Oklahoma. With campuses that include Owasso High School, the Owasso Ninth Grade Center, Owasso Junior High East and West, and more than a dozen elementary schools, the district serves a large geographic area and maintains a commitment to academic excellence, competitive athletics, and robust fine-arts programs. Cornerstone Homes has built for many families who specifically selected their lot based on school attendance zones, and we are happy to discuss how different neighborhoods feed into specific campuses. A custom home builder in Owasso OK should understand that schools often drive the building decision, and we factor that into every consultation.
The US-169 corridor is the commercial backbone of Owasso, lined with restaurants, medical offices, retail centers, and entertainment venues that give residents the convenience of a major metro area without the congestion of downtown Tulsa. Families enjoy quick access to grocery stores, fitness centers, and dining along this route while still returning home to quiet, well-maintained neighborhoods. Owasso also features outstanding parks and recreation facilities, including Rayola Park with its splash pad and walking trails, Veterans Park with sports fields and pavilions, and the Owasso YMCA, which serves as a community hub for fitness and youth programs. Many of the homeowners we work with prioritize proximity to these amenities, and Cornerstone helps them find lots and design floor plans that maximize the Owasso lifestyle.
At Cornerstone Homes & Properties, our design-and-build process eliminates the disconnect that plagues traditional construction. Rather than hiring an architect, waiting months for blueprints, and then bidding the project to multiple contractors, our clients sit down with an in-house design team that understands construction costs in real time. We create custom floor plans and elevations tailored to your family, your lot, and your budget — and because the same company handles both design and construction, the transition from paper to job site is seamless. Every detail you approve in the design phase is faithfully executed in the field. This integrated approach has been a cornerstone of our business for more than 20 years and is one of the key reasons families seeking home construction in Owasso Oklahoma choose to work with us.
Transparent pricing is another differentiator that sets Cornerstone apart from other builders in the Owasso market. We provide detailed, line-item estimates before construction begins so you know exactly where every dollar is going. There are no hidden allowances, no vague categories, and no surprise change orders. If an unexpected site condition arises — and in Oklahoma, they occasionally do — we communicate immediately, present options, and let you make an informed decision. This level of honesty and openness has earned us a loyal client base across Rogers County, Tulsa County, and the surrounding region. When you hire Cornerstone as your custom home builder in Owasso OK, you can trust that the price we quote is the price you will pay.
Beyond ground-up custom homes, Cornerstone is a trusted partner for whole-home renovations and additions in Owasso. Many of the city's established neighborhoods — including areas around Main Street, Bailey Ranch, and the Stone Canyon community — feature homes built in the 1990s and early 2000s that are structurally sound but ready for updated kitchens, expanded master suites, modernized bathrooms, or energy-efficient windows and insulation. Our renovation team approaches each project with the same precision we bring to new construction, carefully protecting existing finishes while transforming the rooms that matter most. Whether you want to open up a closed floor plan, add a second-story bonus room, or completely reimagine your kitchen, Cornerstone has the design talent and field experience to deliver results that exceed expectations.
Kitchen renovations are consistently among our most requested projects in Owasso. The kitchen is where Oklahoma families gather — cooking, doing homework, entertaining friends — and a thoughtful remodel can redefine how your entire home functions. Cornerstone designs kitchens with custom cabinetry, durable quartz or granite countertops, center islands with seating, upgraded appliances, and layered lighting plans that balance task illumination with ambient warmth. We also address the details that matter behind the walls, including plumbing updates, electrical upgrades, and improved ventilation. The result is a kitchen that looks beautiful on day one and performs flawlessly for decades.
Outdoor living is an essential part of the Oklahoma lifestyle, and Owasso homeowners increasingly turn to Cornerstone for screened-in porches, covered patios, and outdoor kitchen additions. The spring and fall seasons in northeastern Oklahoma are long and mild, and a well-designed outdoor space lets you enjoy them without battling mosquitoes, summer heat, or unpredictable rain. We build screened porches that seamlessly extend your living area, with ceiling fans, lighting, and finishes that complement your home's interior. For homeowners with larger lots, we also construct detached garages, workshops, and boat houses — functional outbuildings that serve practical needs while matching the architectural character of the primary residence.
Owasso's mix of established and new subdivisions means that Cornerstone works across a wide range of lot types and neighborhood covenants. Newer developments on the north and east sides of the city often come with architectural review boards, specific setback requirements, and design guidelines that must be followed. Older neighborhoods may have fewer restrictions but present unique challenges related to lot grading, mature trees, and existing utilities. In both cases, Cornerstone handles the due diligence — reviewing covenants, coordinating surveys, managing permit applications, and scheduling inspections — so that your building experience is smooth and stress-free. Our familiarity with both the City of Owasso permitting process and the Tulsa County and Rogers County requirements ensures that nothing falls through the cracks.
One of the questions we hear most often from Owasso clients is how we compare to the large production builders that dominate the local market. The answer is simple: Cornerstone builds your home, not a version of someone else's. Production builders rely on a limited catalog of floor plans and predetermined material packages. Cornerstone starts with a blank sheet of paper and your family's specific needs. Want a mud room that can handle three kids' sports gear? A home office with built-in bookshelves and soundproofing? A master closet designed around your actual wardrobe? We design and build those details into the home from the start rather than offering them as costly upgrades after the fact. This bespoke approach costs less than most people expect and delivers a home that feels unmistakably yours.
Owasso sits at the intersection of suburban convenience and northeastern Oklahoma's natural beauty. From your front porch you can reach Tulsa's employment centers, medical facilities, and cultural attractions in under 20 minutes, yet the rolling hills, wooded lots, and open skies of Rogers County are just minutes to the east. Cornerstone Homes & Properties is proud to serve this vibrant community with the same dedication, craftsmanship, and integrity we bring to every project in our service area. If you are considering building a custom home, renovating your existing home, or adding an outdoor living space in Owasso, we invite you to contact our team for a no-obligation consultation. With over 20 years of experience, in-house design capabilities, and a commitment to transparent pricing, Cornerstone is the partner you can trust to turn your vision into reality.
Our Home Addition Process
Cornerstone Homes designs and builds home additions in Claremore, Rogers County, and the Tulsa metro area. From room additions and second stories to sunrooms and in-law suites, our experienced team seamlessly extends your living space—engineered for Oklahoma soil conditions and built to match your existing home perfectly.
For many families in Rogers County, their home sits on the right street in the right school district with the right neighbors—but it no longer has the right amount of space. Maybe a second child arrived, an aging parent needs a place to stay, or years of working from a cramped spare bedroom have finally hit their limit. Moving would solve the square footage problem, but it would also mean leaving behind the community ties, the short commute on US-66 to Tulsa, and the mature trees that took twenty years to grow. That is exactly why home additions have become one of the most requested services at Cornerstone Homes. A well-planned addition gives Claremore and northeastern Oklahoma homeowners the extra space they need without the disruption and expense of selling, buying, and relocating. Real estate transaction costs alone—agent commissions, closing fees, moving expenses—can consume tens of thousands of dollars that are better invested into the home you already own. Our clients consistently tell us that adding on was not only the more practical choice, but the more personal one: they got exactly the space they wanted, in exactly the place they wanted it.
Home additions come in many forms, and the right approach depends on your property, your budget, and how you plan to use the new space. A ground-level room addition is the most common option we build in the Claremore area—it extends the footprint of your home outward to create a new bedroom, family room, home office, or expanded kitchen. For homeowners on tighter lots or in neighborhoods with setback restrictions, a second-story addition builds upward instead of outward, effectively doubling available living space without consuming yard area. Sunroom additions are popular across Rogers County for families who want a light-filled space that bridges indoor comfort and outdoor beauty, perfect for enjoying Oklahoma’s long autumn evenings without the mosquitoes. In-law suites—sometimes called accessory dwelling units—are increasingly requested by Claremore families caring for aging parents; these self-contained living quarters include a bedroom, bathroom, kitchenette, and private entrance, giving loved ones independence while keeping them close. Cornerstone Homes has built every type of addition across northeastern Oklahoma, and we guide you through the pros and cons of each so you make the best decision for your family and your property.
One of the most critical factors in any home addition in northeastern Oklahoma is the foundation. Rogers County sits on a mix of clay-heavy soils, sandy loams, and limestone-influenced substrates that behave very differently under load. The expansive clay soils common throughout the Claremore and Owasso areas swell when saturated during spring rains and shrink during the dry summer months, creating cyclical ground movement that can crack slabs and shift pier footings if not properly addressed. Before we design a single wall, our team conducts a thorough site evaluation that includes reviewing soil composition and drainage patterns specific to your property. We specify foundation systems—whether monolithic slab, pier and beam, or hybrid designs—that account for these soil conditions and tie into your existing foundation to prevent differential settlement. Proper drainage planning around the new addition is equally important; we grade the surrounding landscape, install French drains or surface channels where needed, and ensure water is directed away from both the new and existing structures. This foundation-first approach is not glamorous, but it is the reason our additions in Rogers County remain structurally sound for decades while others develop cracks and moisture problems within a few years.
The hallmark of a successful home addition is invisibility—when it is done right, no one can tell where the original house ends and the new space begins. Achieving that level of seamless integration requires careful attention to rooflines, exterior materials, window styles, trim profiles, and interior finishes. At Cornerstone Homes, our in-house design team studies your existing home’s architectural character before drawing a single line. We match roof pitch and overhang dimensions, source siding and brick that blends with your current exterior, and align interior ceiling heights, baseboard profiles, and door casing styles so the transition between old and new is invisible. For older homes in established Claremore neighborhoods, this can mean sourcing discontinued materials or custom-milling trim to replicate original details. We also address the connection point between the existing structure and the addition with engineered flashing systems and properly detailed weather barriers, ensuring the junction is watertight even during the severe thunderstorms common in northeastern Oklahoma. The result is an addition that looks and feels like it has always been part of your home—because from a design and construction standpoint, it truly is.
Energy efficiency is a major consideration when adding onto a home in the Tulsa metro area, where summer temperatures regularly exceed 100 degrees and winter ice storms can send the thermometer plunging below zero. A poorly planned addition can overwhelm your existing HVAC system, driving up utility bills and leaving the new space uncomfortable. Cornerstone Homes prevents this by designing each addition with its own thermal performance in mind. We install high-performance insulation in walls, ceilings, and floors—often exceeding current Oklahoma energy code requirements—and specify low-E, double-pane windows that reduce heat gain in summer and heat loss in winter. We evaluate your existing HVAC system’s capacity and either extend ductwork with properly sized runs or install a dedicated mini-split system for the addition. Some additions increase the square footage to a degree that a second HVAC unit is required; together with the homeowner we decide the best option for your home, delivering better comfort and efficiency. Electrical service is assessed as well; older homes in Claremore may need a panel upgrade to handle the additional circuits required for the new space. LED lighting, smart thermostats, and energy-efficient appliances round out our approach, ensuring your addition performs as well as—or better than—the rest of your home. This attention to building science keeps your monthly operating costs low and your indoor environment comfortable year-round.
If your home is running out of room but your heart is not ready to leave, a home addition with Cornerstone Homes is the answer. We have helped hundreds of families across Claremore, Rogers County, and the greater Tulsa metro expand their homes without sacrificing quality, comfort, or curb appeal. Our design-build process means one team handles everything—design, engineering, permitting, construction, and finishing—so there are no communication gaps and no finger-pointing between separate contractors. Contact us today for a free, no-obligation consultation. We will visit your home, discuss your space needs and budget, evaluate your property’s soil and structural conditions, and provide an honest assessment of what your addition will involve. Whether you need a single extra bedroom or an entire second floor, Cornerstone Homes has the experience and local expertise to deliver an addition that feels like it was always meant to be there.
What Sets Our Home Addition Apart in Owasso
Seamless Architectural Integration
Every addition we build in the Claremore area is designed to look and feel like an original part of your home. Our in-house team studies your existing roof pitch, siding material, window proportions, and trim details before drafting the addition’s design. We source matching or complementary materials and align interior ceiling heights, flooring transitions, and molding profiles so the connection between old and new is invisible. For homes in established Rogers County neighborhoods with unique architectural character, we custom-mill trim and source specialty materials to ensure a flawless visual match inside and out.
Foundation & Structural Engineering
Oklahoma’s expansive clay soils and variable substrates demand careful foundation engineering for any addition. Cornerstone Homes evaluates your property’s soil composition, drainage patterns, and existing foundation type before specifying the right system for your new space—whether monolithic slab, pier and beam, or a hybrid approach. We engineer the connection between the new and existing foundations to prevent differential settlement, a common failure point in Rogers County additions. Proper grading, drainage channels, and moisture barriers protect both structures from the cyclical soil movement driven by Oklahoma’s wet springs and dry summers.
Roofline Matching
A mismatched roofline is the fastest way to spot a poorly planned addition. At Cornerstone, we design roof structures that continue your existing pitch, overhang, and fascia details so the addition looks original from every angle. We use engineered tie-in methods and flashing systems that create a watertight connection at the junction—critical in northeastern Oklahoma where severe thunderstorms and driving rain test every joint. Shingle matching, drip-edge alignment, and soffit ventilation continuity are all addressed during the design phase, ensuring your expanded roofline performs and looks its best for decades.
Electrical & HVAC Extension
Adding living space means adding electrical circuits, lighting, and climate control. We assess your existing HVAC system’s capacity and either extend ductwork with properly sized runs or install a dedicated ductless mini-split system—whichever delivers better comfort and efficiency for your Claremore home. Electrical panels in older Rogers County homes often need upgrading to safely handle the additional load. Our licensed electricians ensure code-compliant wiring, properly placed outlets, dedicated circuits for high-draw appliances, and modern LED lighting throughout the new space, all designed to integrate cleanly with your existing systems.
Interior Finishing
The interior of your addition should feel like a natural extension of your home, not a separate space tacked onto the side. Cornerstone’s finishing crews match drywall textures, paint sheens, flooring materials, and trim profiles to your existing interior. We handle every detail—baseboards, door casings, crown molding, hardware finishes, and cabinetry—so the transition from original home to new addition is seamless. For Claremore homeowners updating their entire home during the project, we coordinate full-house finish upgrades that tie everything together into a cohesive, modern interior while maintaining Rogers County charm.
Permit & Code Compliance
Home additions in Rogers County and the Claremore area require building permits, structural inspections, and compliance with local zoning setbacks and codes. Cornerstone Homes manages the entire permitting process—from initial applications and plan submissions to scheduling inspections and securing final sign-off. Our familiarity with Rogers County building department requirements, Claremore city ordinances, and Oklahoma state residential codes means fewer delays and no surprises. We ensure your addition meets all structural, electrical, plumbing, and energy code requirements so you have complete peace of mind and full legal compliance from day one.

Home Addition FAQs for Owasso Homeowners
- How much does a home addition cost in Claremore, Oklahoma?
- Home addition costs in the Claremore and Rogers County area vary significantly based on the type and size of the addition, foundation requirements, finishes, and mechanical system needs. A basic room addition typically starts at a lower price point per square foot than new construction because the core home already exists, but costs increase for additions requiring complex foundation work, second-story structural support, or high-end finishes. During your free consultation, we evaluate your specific property and design goals, then provide a detailed, line-item estimate so you know exactly what to expect. Our transparent budgeting process eliminates hidden fees and surprise change orders throughout the project.
- How long does it take to build a home addition?
- Most home additions in the Claremore area take between three and six months from design finalization to completion, depending on size, complexity, and scope. A single-room addition with standard finishes typically falls on the shorter end, while a second-story addition or in-law suite with a full kitchen and bathroom requires more time. Permitting in Rogers County generally takes two to four weeks, and we factor Oklahoma’s seasonal weather patterns—particularly spring storms and summer heat—into our construction schedule. Our design-build approach saves time compared to hiring separate architects and contractors because design, engineering, and construction overlap rather than running sequentially.
- Can I live in my home during the addition construction?
- Yes, most homeowners stay in their home throughout the addition process, and we plan every project with that in mind. We establish clear construction zones, seal openings between the existing home and the work area to control dust and weather exposure, and maintain safe access to your home at all times. Our crews follow a consistent daily schedule so you know when work will start and stop. Temporary utility interruptions—for example, when tying new plumbing or electrical into existing systems—are scheduled in advance and kept as brief as possible. Claremore families consistently tell us the process was far less disruptive than they expected.
- How do you match the addition to my existing home’s style?
- Matching is one of our core specialties. Before we begin design, our team documents every detail of your existing home—roof pitch, siding type and color, window style and proportions, brick pattern, trim profiles, and interior finishes. We source matching or closely complementary materials and, when exact matches are unavailable for older Claremore homes, we custom-mill trim or work with specialty suppliers to replicate original details. On the interior, we match drywall textures, paint colors, flooring transitions, and hardware finishes so the addition feels like an original part of the home. The goal is always invisibility—a completed addition that no one can distinguish from the original structure.
- What permits are needed for a home addition in Rogers County?
- Home additions in Rogers County require a building permit that covers structural, electrical, plumbing, and mechanical work. Depending on your location within the county or city limits of Claremore, additional zoning reviews may be required to confirm setback compliance, lot coverage limits, and easement clearances. If the addition includes plumbing—such as a bathroom or kitchen—a separate plumbing permit is typically required. Cornerstone Homes handles the entire permitting process on your behalf, from preparing and submitting plans to scheduling all required inspections throughout construction. Our established working relationship with the Rogers County building department and Claremore city permitting office helps ensure a smooth, efficient approval process.
