You’ve outgrown your home, but you love your neighborhood. Let’s build the space you need without losing the home you’ve invested in.
Select your situation below
Your family has grown, your needs have changed, and every room is doing double duty. Maybe you need space for a parent to move in, a home office with an actual door, or a bedroom that isn’t also a playroom. Your house was designed for a different version of your life.
But you love your neighborhood, your schools, and your commute. And in today’s market, uprooting your family to find a bigger home doesn’t make financial sense, especially if you’re sitting on a good mortgage rate and a large lot. A well-designed addition gives you exactly what you’ve been missing.
Before we ever draw a single line, we sit down and talk about how your household functions: who needs what, where the friction points are, and what “enough space” actually looks like for your family. The result is an addition that adds the right square footage, whether that’s a main-level primary suite, a semi-private space for a family member, a proper home office, or a great room that finally gives everyone room to breathe.
We match your existing roofline, siding, window styles, and decorative accents so the addition feels like part of the original design, not something bolted on later. When we can’t perfectly match old materials to new, we repaint or re-side the impacted facades entirely so there’s no visible seam. Inside, we align drywall texture, trim, doors, and flooring so the transition is invisible.
Nothing is worse than designing your dream addition and finding out your lot, setbacks, or zoning won’t allow it. Before we begin, our team conducts a complete feasibility study: lot lines, setbacks, access, zoning, permit history, HOA requirements, and more. That means the plan you fall in love with is one we can actually build. No surprises. No redesigns from scratch.
You’ve outgrown your home, but your lot is small, steep, or subject to environmental restrictions. A traditional side or rear addition isn’t practical, or isn’t possible. That doesn’t mean you’re out of options.
When building out isn’t feasible, we build up or down. An attic conversion, often with a gable pop-out to increase headroom, can add a full story of living space. On a hillside property, a multi-story addition or basement dig-out can unlock significant square footage that a flat-lot addition never could. We’ll evaluate your specific site and tell you honestly what’s possible.
Adding a story or building into a hillside changes how a home reads from the street. We design carefully to preserve your home’s overall aesthetic: matching siding details and accents, making cosmetic adjustments to the front entry to keep it in scale, and coordinating window and door styles so the addition looks like it was part of the original plan.
The stair connection point is one of the most consequential decisions in a vertical addition. We’re strategic about where it lands. By repurposing a pantry or closet, or borrowing from a small room and folding the remainder into an adjoining space, we make sure you don’t end up with dead zones or awkward traffic patterns. Every square foot works.
The bedroom and bathroom you use every day are upstairs. The entry has steps you’re already thinking about. You want to stay in this home for the long haul, but right now, it isn’t designed for it.
We design and build primary suite additions guided by Universal Design principles, such as, wide doorways, accessible layouts, and zero-threshold entries. Your space is safe, beautiful, and fully usable for all ages and abilities. We include laundry in the suite so there’s no need to carry baskets across the house, and we make sure the finished floor height transitions seamlessly from old to new.
An addition is a natural opportunity to improve the exterior while we’re already mobilized. As part of the sitework, we can regrade parts of the yard to eliminate steps into the home, pour wider sidewalks, remove dangerous drop-offs along the edges, and add attractive handrails — making the whole property safer without it looking like a retrofit.
We can create a new entrance into the addition or rework the existing front entry to provide a wide, covered landing with attractive railings and a zero-threshold entry. The result is a home that’s welcoming, accessible, and protects your resale value, because a home that works for everyone is a home that more buyers can picture themselves in.
Every home addition starts with a conversation, and ends with a space that looks like it was always meant to be there. Here's how we make that happen.
We start with a short phone call to learn about your vision, timeline, and investment expectations. There’s no pressure and no obligation. If we’re a great fit, we’ll schedule a time to come see your space. If we’re not, we’ll tell you honestly and point you in the right direction. Either way, you’ll leave the call with more clarity than you started with.
We visit your home to understand how you live, what’s not working, and what your dream looks like. We encourage all decision-makers to be present so everyone is on the same page from the start. We take detailed measurements and talk through early feasibility and investment ranges — so you know what’s realistic before moving forward.
We present a detailed Project Development Agreement that outlines exactly what your project involves, how we work, and what to expect along the way. A $1,000 design retainer kicks things off to begin the design phase — and it’s fully credited back to your construction contract when you decide to move forward. This is where the partnership officially begins.
Our in-house designer creates conceptual drawings, renderings, and mood boards so you can see your possibilities before any decisions are locked in. We’d rather you fall in love with a direction than guess at it. This phase is all about making sure we fully understand your vision and give you the chance to refine it before we go deeper.
We take your chosen direction and finish it completely — refined renderings, full material selections, detailed specifications, and trade walkthroughs with every subcontractor. By the end of this phase, you’ll have a fixed-price contract you can count on. No guessing, no vague estimates. Just a real number for a fully designed project.
Once the contract is signed, we apply for permits, schedule our team, and order materials. We don’t break ground until everything is ready to go — which means your project runs on a real schedule. Your dedicated Project Director is with you every step of the way, keeping you informed with daily updates and photos through your private client portal. When we hand back your keys, the only thing left to do is enjoy it.

Addition pricing is based on square footage, plus the cost of whatever you’re putting inside it. A simple bedroom or family room? Use the square footage pricing below. A primary suite addition? Start with the square footage pricing and add the cost of a primary suite.
One important thing to know: the smaller the addition, the higher the cost per square foot. The most expensive parts of any addition (site work, foundation, and tying into existing utilities) cost roughly the same whether you’re adding 200 square feet or 600. That fixed cost gets spread over fewer square feet in a smaller addition, which drives the per-square-foot price up.
Timeline: 12 to 16 weeks
Timeline: 14 to 18 weeks
Timeline: 16 to 20 weeks
Base pricing includes: single large room, engineered hardwood flooring, windows, limited cabinetry/closets, flat site, limited excavation, utility tie-ins, asphalt shingles, and off-the-shelf siding to match existing.
Many homeowners use an addition as the perfect opportunity to refresh the rest of the home at the same time. Common upgrades include:
New siding, roofing, gutters, and exterior paint
New windows and exterior doors
Covered outdoor living areas via roof extensions
Curb appeal and landscaping improvements
Upgraded electrical, plumbing, and HVAC systems
Additional insulation and energy efficiency upgrades
New flooring, trim, and interior paint throughout
We're proud of the spaces we build, but hearing how those spaces have changed our clients' lives is what means the most to us.
That depends on the jurisdiction where your property is located and your existing site conditions — things like lot lines, setbacks, zoning, and access. Our feasibility study answers all of those questions before we start designing, so you know exactly what’s possible on your specific property.
No. We complete and weatherproof the exterior shell of the addition before we ever break through to connect the interior spaces. Your existing home stays dry and protected throughout he process.
Absolutely. There may be some noise and brief interruptions to electrical, plumbing, or HVAC service, but daily life continues as normal until we connect the new and existing interior spaces. Moving out is rarely necessary for a home addition
The most expensive parts of any addition are the site work, the foundation, and the tie-in to your existing electrical, HVAC, and plumbing systems. Those costs are driven more by the specialized equipment and skilled labor required than by the amount of material used.
An addition with 40 feet of foundation requires the same backhoe and excavation expert as an addition with 120 feet of foundation. Trenching a few less feet or using a few less bags of concrete doesn’t move the needle much on overall cost. With fewer square feet to spread those fixed costs across, the per-square-foot price goes up on smaller additions.
Before we begin designing, our team conducts a thorough review of your property: lot lines, setbacks, access, zoning regulations, permit history, permitting requirements, design standards, and any applicable HOA rules. This ensures that the design you fall in love with is actually buildable and financeable before you invest in it. No wasted time. No expensive redesigns.
A home addition adds living space that is fully connected to and integrated with your existing home. It functions as part of the main house. An Accessory Dwelling Unit (ADU) is a separate, self-contained living space with its own entrance, kitchen, and bathroom, designed to function independently. Some homeowners add an ADU as part of a larger addition project. Not sure which is right for your goals? We can help you think it through.
Yes. Our team manages the entire permitting process from start to finish. Home additions are subject to more jurisdictional review and compliance requirements than most other remodel projects — which is exactly why you want an experienced team handling it.
Let's find out what's possible on your property and what it would take to build the space your family needs.
