Adding a room to a Camp Swift home usually costs between $85,000 and $190,000 depending on the sub-service, and a sunroom addition typically runs $45,000 to $95,000. We build room additions, second story additions, sunroom additions, bathroom additions, garage additions, and bump-out additions across Bastrop County, and we’re familiar with the particular headaches Camp Swift lots throw at homeowners: unplatted parcels from the old military reservation, older ranch homes with cloth-wrapped wiring, and septic systems that dictate what the county will approve. If you’re planning a Home Addition Contractor project, call (254) 615-3842 for a free estimate with a written price before any work begins.
Why Seedling ADU Austin Is Camp Swift’s Preferred Home Addition Contractor Company

Camp Swift homeowners call us because we understand what opening up a 1970s or 1980s ranch home actually turns up. Our crews work on homes near County Road 367, off of Turkey Trot Trail, and throughout the wooded lots that still follow the old Camp Swift military grid, and they know to expect the unexpected: outdated wiring, termite-damaged sill plates, failed waterproofing, and framing that was never meant to carry a bump-out. Every project starts with an inspection, and every surprise gets documented, priced, and approved in writing before we touch it.

Ben Ortega Leads Every Camp Swift Project
Ben Ortega runs our Camp Swift work the way he’d want it done on his own property: plainly, carefully, and with a written price before a single tool is picked up. When he walks a lot off of Plainview Drive or near the Colorado River basin, he’s looking at parcel lines, septic capacity, and tree preservation, because those are the things that determine whether your addition gets approved the first time or gets flagged by the county. You’ll get his direct line of sight on your project from the first site visit to the 365-Day Done Right Promise at the end.
Sunroom Addition in Camp Swift
A Sunroom Addition in Camp Swift is one of the most practical ways to add living space on a larger wooded lot without triggering the full cost of a stick-built room. Most sunrooms here run between $45,000 and $95,000, and the design almost always has to account for two local realities: hot, humid summers that demand proper ventilation and insect screening, and a potential for flooding from the Colorado River basin that pushes foundations up and calls for moisture-resistant materials. We also have to check the existing structure first, because many Camp Swift homes from the 1970s and 1980s have sill plates and rim joists that termites have been working on for decades.
Elevated Foundations and Moisture Control
Camp Swift’s climate doesn’t forgive ground-level shortcuts. We specify elevated foundation details and proper drainage on sunroom additions so the first heavy spring rain doesn’t find its way under your new floor. Vented skirting, insect screening on all openings, and James Hardie trim that shrugs off humidity are standard here, not upgrades.
What a Sunroom Addition Lets You Live With
Families in Camp Swift use sunrooms as breakfast rooms, play spaces, and quiet spots for teenagers to do homework away from the main living area. Because we write the price before work starts and hold to it unless something hidden is found, you can plan for the cost of the room without worrying that the bill will wander after the crew arrives.

Room Addition Contractor in Camp Swift

A Room Addition Contractor in Camp Swift is usually adding space to a single-story ranch or a manufactured home from the 1970s through the 1990s, and the work ranges from $85,000 to $190,000 depending on the size, the sub-service, and what the existing structure will support. This is where the old military grid comes into play: many local properties were unplatted subdivisions from the 1940s Camp Swift military reservation, so we often have to survey the parcel before any foundation work to confirm the actual boundaries. Oddly shaped lots and deep setbacks can mean a planned addition encroaches on an easement or a historic utility line, and the county will flag that.
Surveying Parcels With Irregular Lines
We opened up a 1970s ranch home off of a wooded lot near the old Camp Swift grid and found original cloth-wrapped wiring and termite-damaged sill plates. Because the permit triggered code upgrades, we had to re-feed the panel, sister the floor joists, and add hurricane ties before framing the sunroom addition, and every surprise was documented, priced, and approved in writing before we touched it. That’s not unusual for Camp Swift. It’s the norm.
Working With Septic and Floodplain Limits
Bastrop County’s rural zoning and floodplain rules constrain most Camp Swift additions. Adding a bedroom means adding a fixture count, and the existing septic system has to be able to handle it legally. We check septic capacity before we draw anything, because there’s no point designing a room the county won’t permit. For homes that sit low near the Colorado River basin, we raise the foundation and detail the waterproofing so a ground-level room stays dry.
Common Home Addition Contractor Problems We See in Camp Swift Homes
- Skipping a septic capacity check before adding a bedroom. The existing system may not legally support the extra fixture count, and the county will not issue the permit. We verify septic capacity before the design leaves the desk.
- Assuming a standard setback on an unplatted Camp Swift parcel. Odd lot lines from the old military grid mean the county can flag an addition for encroaching on an easement or historic utility line. We survey first.
- Framing over existing wall sections without verifying waterproofing and termite damage. A 1970s or 1980s ranch home often hides rot behind the siding, and new framing over it just traps moisture. We open the wall and document what’s there before we build over it.
- Ignoring the Central Texas humidity when choosing materials for a ground-level addition. Moisture-resistant products and proper ventilation are not optional here. They’re the difference between a sunroom that lasts 20 years and one that sweats through its first Camp Swift summer.
Pricing for Home Addition Contractor in Camp Swift, TX
A room addition in Camp Swift typically runs $85,000 to $190,000, while a sunroom addition is usually $45,000 to $95,000. Bump-out additions tend to be on the lower end, second story additions on the higher end. What moves the price is what we find when we open the wall: outdated wiring, damaged framing, failed waterproofing, and the code upgrades a permit triggers once anything is exposed. We handle that with an inspection first, allowances written into the contract, and any surprise priced and approved in writing before we touch it. Call (254) 615-3842 for a free estimate, and you’ll get a written price before any work starts.

FAQs About Home Addition Contractor in Camp Swift
You don’t know until the septic capacity is checked against the fixture count a bedroom addition triggers, and we run that check before we draw anything. Existing Camp Swift septic systems from the 1970s through the 1990s were often sized for the original home, not an added bedroom, and the county won’t issue a permit if the system can’t legally support the addition. Call (254) 615-3842 and we’ll check your system as part of the free estimate.
Yes, it changes everything about the survey and setback work. Unplatted subdivisions from the 1940s Camp Swift military reservation often have irregular parcel boundaries and deep setbacks that don’t match what a standard builder assumes, and the county will flag an addition that encroaches on an easement or a historic utility line. We survey the parcel before foundation work so the permit gets approved the first time.
As soon as the wall is open, the inspector can require the exposed wiring to be brought to current code, which on an older Camp Swift home often means re-feeding the panel, replacing cloth-wrapped wiring, and adding arc-fault breakers. You may also be looking at hurricane ties on the framing, sistered floor joists if there’s been termite damage, and updated waterproofing details. We write those allowances into the contract before we start so the price you approve is the price you pay, and any surprise gets documented and priced in writing before we touch it.
We raise the foundation, specify proper drainage, and use moisture-resistant materials on any ground-level addition in a flood-prone part of Camp Swift. The hot, humid summers and occasional flooding from the Colorado River basin mean elevated foundations and well-screened ventilation are not optional here. We’ll show you the drainage plan and the product choices in writing before you commit.
In most cases, yes, but the attachment detail matters more than anything else on the job. Manufactured homes move differently than site-built homes, so we detail the connection so the addition doesn’t fight the existing structure during temperature swings. We’ll also check the existing support and the county’s requirements for tying the addition to the home before we frame anything. Call (254) 615-3842 and we’ll take a look with you.
