Home Addition in Tulsa, Oklahoma
Cornerstone Homes & Properties brings over 20 years of design-and-build expertise to Tulsa and its surrounding neighborhoods. From Midtown bungalow renovations to new construction in South Tulsa, we deliver custom homes, additions, and remodels with in-house design, transparent pricing, and hands-on project management.
Tulsa, Oklahoma stands as the second-largest city in the state, home to roughly 413,000 residents within the city limits and nearly one million across the greater metropolitan area. Known worldwide as the former Oil Capital of the World, Tulsa has evolved into a diverse, forward-looking city with thriving aerospace, energy, and technology sectors, yet it has never lost the neighborly warmth and civic pride that define Oklahoma living. For families and individuals looking for a custom home builder in Tulsa, OK, Cornerstone Homes & Properties offers the rare combination of small-town values and large-project capability. Headquartered in Claremore — about 30 miles northeast of downtown Tulsa along the Will Rogers Turnpike — Cornerstone has been designing and constructing custom residences, renovations, and outbuildings across northeastern Oklahoma for more than two decades. Our decision to serve the Tulsa market stems from a simple reality: many of our Claremore-area clients work, worship, and socialize in Tulsa, and as word of our craftsmanship spread, Tulsa homeowners began reaching out to us for the same personalized building experience we had delivered throughout Rogers County.
What makes Tulsa such a compelling place to build or renovate a home is the sheer variety of its neighborhoods. Midtown Tulsa, stretching roughly from the Arkansas River north to the Inner Dispersal Loop, is famous for its tree-lined streets, walkable blocks, and eclectic mix of Tudor Revival, Craftsman, and Art Deco residences dating to the early twentieth century. Homeowners in Midtown frequently partner with Cornerstone for thoughtful whole-home renovations that preserve historic architectural character while introducing modern mechanical systems, open floor plans, and energy-efficient windows. Just south of Midtown lies Brookside, a vibrant corridor along Peoria Avenue filled with locally owned shops, restaurants, and bungalows on generous lots. Maple Ridge, immediately east of Brookside, is one of Tulsa's most prestigious historic districts, where stately homes sit beneath mature oaks and the demand for high-quality renovation work remains constant. When you hire a custom home builder in Tulsa, OK who understands these neighborhoods the way Cornerstone does, you gain a partner capable of honoring the character of an older home while upgrading it for twenty-first-century living.
South Tulsa represents a different building opportunity altogether. The corridor stretching south along Memorial Drive, Yale Avenue, and Lewis Avenue toward the Jenks and Bixby school districts features newer subdivisions, larger lots, and a suburban character that appeals to growing families. Home construction in Tulsa Oklahoma's southern reaches often involves ground-up custom builds on half-acre to two-acre tracts, where Cornerstone's in-house design team can create floor plans optimized for the specific topography and orientation of each site. Whether you envision a single-story ranch with an oversized garage, a two-story transitional plan with a main-floor master suite, or a modern farmhouse with board-and-batten siding and a metal roof accent, our team translates your ideas into construction-ready drawings and then builds them with meticulous attention to detail. South Tulsa also offers convenient access to the Creek Turnpike and Highway 169, giving residents quick commutes to employers throughout the metro.
Education is a top priority for many families who choose to build in Tulsa. The Tulsa Public Schools district operates more than 50 elementary schools, along with middle and high school campuses spread across the city. Families in South Tulsa may also fall within the highly regarded Jenks Public Schools or Union Public Schools districts, both of which consistently rank among the best in Oklahoma for academics, athletics, and extracurricular programs. Broken Arrow Public Schools serve portions of the southeastern metro as well. Cornerstone Homes understands that school district boundaries often drive the home-building decision, and we help clients identify lots and neighborhoods that align with their preferred attendance zones. Our familiarity with the geographic boundaries of each district ensures that the investment you make in your custom home also places your children in the educational environment you value most.
Tulsa's cultural and recreational amenities rival those of cities many times its size. The Gathering Place, a 66-acre riverside park that opened to international acclaim, offers world-class playgrounds, gardens, skating rinks, and event spaces that have become a centerpiece of daily life for Tulsa families. Philbrook Museum of Art, housed in a 1920s Italianate villa surrounded by formal gardens, draws visitors from across the country, while the Gilcrease Museum holds one of the finest collections of Western American art and artifacts in the world. Downtown Tulsa's Arts District pulses with live music venues, galleries, and restaurants, anchored by the BOK Center and the ONEOK Field baseball stadium. Residents who build custom homes in Tulsa enjoy easy access to all of these attractions, and Cornerstone designs homes that complement the active, culturally rich lifestyle the city affords — from mudrooms sized for gear-laden families returning from The Gathering Place to wine rooms and entertaining spaces inspired by Tulsa's vibrant dining scene.
Cornerstone Homes & Properties differentiates itself from other Tulsa-area builders through a fully integrated design-and-build process. Many production builders offer a limited catalog of pre-drawn floor plans with a fixed set of upgrade options. Cornerstone takes the opposite approach. Every home we build starts with a blank sheet of paper and a conversation about how you actually live. Our in-house designers sit with you — at our Claremore office, at a Tulsa coffee shop, or on your lot — and sketch concepts in real time. We discuss room adjacencies, natural light, storage needs, outdoor connections, and the small details that turn a house into your home. Because design and construction operate under one roof, pricing feedback is immediate: if a design decision has a significant cost impact, you know about it before the first stud is framed, not after. This transparency is central to who we are, and it is a primary reason Tulsa homeowners choose Cornerstone over larger, less personal builders.
Our construction methodology reflects over 20 years of building in the Oklahoma climate. Tulsa's weather ranges from ice storms in January to triple-digit heat in July, with severe thunderstorms and occasional tornadoes punctuating the spring and fall. Cornerstone builds to exceed code requirements, incorporating features such as engineered roof trusses rated for high wind uplift, continuous exterior insulation for thermal performance, advanced moisture management details at windows and wall penetrations, and storm shelter options that meet FEMA 361 standards. We have built through enough Oklahoma weather cycles to know which products and techniques perform over the long term and which do not. That hard-won experience translates directly into a more durable, energy-efficient, and comfortable home for you.
Beyond new custom home construction, Cornerstone is a trusted partner for major renovation and addition projects throughout Tulsa. Kitchen renovations rank among our most requested services, and for good reason — the kitchen is the heart of every Oklahoma home. Cornerstone kitchen remodels feature custom cabinetry, quartz or granite countertops, professional-grade appliances, thoughtful lighting design, and functional layouts that eliminate the bottlenecks common in older Tulsa floor plans. We also design and build room additions ranging from expanded master suites and sunrooms to second-story pop-ups that add square footage without sacrificing yard space. For homeowners in Midtown, Brookside, or Maple Ridge, our renovation team approaches each project with a preservationist's eye, ensuring new work integrates seamlessly with existing trim profiles, window proportions, and rooflines.
Outdoor living construction is another specialty we bring to the Tulsa market. Oklahoma's generous spring and fall seasons make screened-in porches, covered patios, and outdoor kitchens some of the most enjoyed spaces in any home. Cornerstone designs these spaces as true extensions of the interior, matching materials, scale, and finish quality so the transition from inside to outside feels effortless. We also build detached garages, workshops, and accessory structures for Tulsa homeowners who need dedicated space for hobbies, vehicles, or home-based businesses. Every outbuilding we construct meets the same structural and aesthetic standards as our primary residences.
Navigating Tulsa's permitting landscape requires experience and attention to detail. The City of Tulsa enforces its own zoning ordinances, building codes, and stormwater management requirements, and projects in historic overlay districts such as Maple Ridge or Swan Lake carry additional architectural review steps. Cornerstone handles every permit application, plan review submission, and inspection coordination on your behalf. We maintain productive working relationships with the Tulsa Development Services department, and our construction documents are prepared to the level of detail that reviewers expect, which translates into faster approvals and fewer revision cycles. For projects that fall within Tulsa County's unincorporated areas or adjacent municipalities like Jenks and Bixby, we are equally familiar with the applicable regulations.
Tulsa's road network makes commuting and daily life convenient regardless of where you build. Interstate 44 and the inner-loop expressway system connect all quadrants of the city, while U.S. Highway 75, Highway 169, and the Broken Arrow Expressway (Highway 51) provide efficient north-south and east-west routes. The Creek Turnpike links South Tulsa to Broken Arrow and points east, and the Will Rogers Turnpike connects Tulsa to Claremore, Vinita, and the Missouri border. Tulsa International Airport sits just a few miles northeast of downtown. Many Cornerstone clients appreciate that our Claremore headquarters is a straight 30-mile drive up Highway 66 or the Turnpike, making site visits, material selections, and face-to-face meetings easy to schedule without the delays that often plague builders who are spread thin across too wide a geography.
When you partner with Cornerstone Homes & Properties for your Tulsa project, you are choosing a builder whose reputation has been built one home at a time over more than 20 years. We do not mass-produce houses; we craft them. Every floor plan is original, every budget is respected, and every timeline is communicated honestly. Our clients in Midtown, South Tulsa, Brookside, and beyond will tell you that what sets Cornerstone apart is the personal relationship — you have Craig's cell phone number, you get weekly progress updates with photos, and you never wonder what is happening on your job site. If you are ready to build a custom home, renovate a historic gem, or add the outdoor living space you have always wanted in Tulsa, Oklahoma, we would welcome the opportunity to sit down, listen to your vision, and show you how Cornerstone turns plans into places people love to come home to.
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 Tulsa
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 Tulsa 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.
