Your location works. Your layout doesn't. We design and build home additions in North Myrtle Beach that integrate structurally and visually with what you already have—managed by a licensed SC general contractor.
A home addition adds new square footage to an existing structure—a full room, a bump-out, a second story, or expanded garage space. The structural tie-in is where additions succeed or fail. Rooflines, framing connections, utility extensions, and exterior details all have to be planned before a wall gets opened. We do that work up front.
Additions make sense when the lot and location are right but the layout isn’t. Primary suites, home offices, enlarged living areas, and garage expansions are common drivers. We review setback requirements, existing structural conditions, and utility access before confirming a scope—so there are no surprises mid-build.

Common questions about additions in North Myrtle Beach.
Second-story additions, in-law suite additions (mother-in-law suites and ADUs), garage additions, primary suite additions, room additions, sunrooms, and bump-outs are the most common scopes we plan and build. If you're not sure which approach fits your goals, share your situation and we'll help you figure it out.
Yes. In-law suites (also called mother-in-law suites or accessory dwelling units) are one of the most common addition types we plan in the Grand Strand. Whether attached, detached, or above a garage, the build typically includes a full kitchen or kitchenette, bathroom, separate entry, and HVAC—coordinated to meet local zoning, setback rules, and Horry County permit requirements.
Yes, with a structural assessment first. Second-story additions require evaluating the existing foundation, load-bearing walls, and load paths to confirm the existing structure can carry the new floor—or what reinforcement is needed if it can't. In coastal SC, wind-load engineering and FEMA flood zone elevation rules also factor into the design. We coordinate the engineering and permitting before any framing starts.
Most do. Any addition that involves structural work, new electrical, or plumbing will typically require building permits in Horry County and inspections. We identify what applies to your specific scope and coordinate the permitting path so it doesn't slow the build.
Size, structural complexity, inspection timing, and material lead times all factor into the schedule. After the walkthrough and planning session, we give you a realistic timeline—not a range wide enough to mean nothing.
Yes. Rooflines, exterior siding or trim details, window profiles, and interior finishes are all planned so the new space reads as part of the original home—not as something tacked on.
If your goals require a complete layout reset or a square footage increase that would exceed what an addition can reasonably achieve on your lot, new construction may make more sense. We can walk through both options and help you decide. See our Custom Home Builder page.

"We recently had our bathroom completely remodeled by Baldwin Builders, and they did an absolutely amazing job! From the initial consultation to the final walkthrough, the entire team was professional, communicative, and attentive to every detail. They stayed on schedule, kept the worksite clean every day, and minimized disruptions to our home. We couldn’t be happier with the results and highly recommend Baldwin Builders!!"
Tina Gibbins
"We were referred to Baldwin Builders by a friend and are so pleased. Our newly purchased vacation condo needed to be completely painted, bedroom flooring replaced to match existing, a new kitchen fixture and desk area built. George walked the property, gave great suggestions and had a proposal to us in a few days. His communication with calls and photos and his responsiveness was fantastic. They matched the existing flooring perfectly and made my workspace vision come to fruition. If you want quality work done, call Baldwin Builders."
Bill Baker
"We recently purchased an older home in SC knowing some work would be required before leaving our home state. We turned to our many long-term acquaintances in the area for contractor recommendations. Repeatedly, Baldwin Builders came up on the top of every list. Baldwin Builders was sensitive to our absence during the project and contacted us almost daily with project status and solutions to any unforeseen challenges. I would characterize Baldwin Builders as a company of uncompromising integrity and pro-active communicators."
Phillip Wisdom
"Baldwin Builders recently remodeled our bathrooms, and we couldn’t be happier with the outcome. From the initial consultation to the final walkthrough, their team was professional, responsive, and detail-oriented. They helped us choose modern fixtures, updated the flooring, and improved the overall layout. The transformation is incredible—our bathrooms now feel like a high-end spa. Highly recommend Baldwin Builders for any remodeling needs!"
Vincent Padavano
"I have nothing but great things to say about Baldwin Builders. I had a guest bathroom remodel done by them and it turned out amazing. They paid attention to detail, cleanliness and finished the job within a short/appropriate amount of time. I would definitely recommend this young, professional, up-incoming business to anyone for home repair/updating needs."
Thomas Veith
"I hired Baldwin Builders to do a full renovation on my beach vacation rental and have nothing but great things to say. Their head sales guy, George, was with me through the entire project displaying perfect communication. He went above and beyond to hold everyone accountable and shared my vision as if it was his own. Larson, the owner, delivered my estimate and acted in my best interest throughout the entire project displaying honesty and transparency."
James Moye
"George is extremely accommodating & professional. Great communication! Also met with his brother Larson. Nice guy & it’s very impressive they created such an excellent business together. I needed a sub floor from recent demo go bad & they got on it & handled so quick. I’m continuing my relationship with these 2 brothers & crew."
Thomas Neat
"I don’t know where to begin explaining how happy I am with my sunroom. It was a screened porch and I said I wanted a room to use all year round with a view of the pond behind me. Beyond my expectations. George, Larson, and crew worked fast, kept me up to date, treated my family and even my pets with respect. I will not hesitate to call them if I have another project."
Andrew Zaloom
"I could not be happier with the quality and service that both Larson and George provided. From the initial consultation to delivery, they were thorough, honest, and attentive. Within a few days, they were able to do an extensive door replacement and structural repair. I own several rental properties in the area and this was the first group I’ve worked with that did not over promise and under deliver."
Gina Thomas
"After building a new house and being left without shower doors for our walk in luxury tile shower it was a major burden. We researched and looked for a couple of weeks to find a builder to install shower doors and Baldwin Builders came in showed us our options for our price range. Larson is extremely efficient and knowledgeable. The installation was easy and perfection. If you are looking for a contractor who cares and is professional, Baldwin Builders is your company."
Ed Cristina
"Hired Baldwin Builders last minute to build a staircase for my porch. We needed it done quickly. I gave them pictures on a Friday and it was DONE Monday!! AND it was absolutely perfect; exactly what we wanted and hundreds less than the other 2 companies we called. Ask for George or Larson: both were great!!"
