A room addition in Lake Worth typically runs $175 – $285 per square foot for site-built work, with most full-size additions landing between $52,000 and $128,000 depending on foundation type, finish level, and whether you’re on city sewer or septic. That’s the honest range we quote from before a single shovel turns. Benson ADU Fort Worth serves homeowners throughout Lake Worth with written pricing, a 365-Day Done Right Promise, and crews who know the difference between a Pier-and-beam ranch on Azle Avenue and a newer slab home off Boat Club Road. If you’re weighing a sunroom, an extra bedroom, or a full second living space, call (682) 204-9686 and we’ll scope it properly.
Why Benson ADU Fort Worth Is Lake Worth’s Preferred Room Addition Contractor Company
Lake Worth homeowners keep our number because we treat county and city permitting as two different jobs, not one blurry “we’ll handle it.” Most additions inside city limits go through Lake Worth’s building department. Properties on acreage off Ten Mile Azle Road or north of Loop 820 often fall under Tarrant County jurisdiction, which changes setbacks, inspection schedules, and which office actually stamps the final. Our team tracks that before we quote, so the price you see is the price you pay.
We’ve done room additions around the older ranch neighborhoods near Cherokee Drive, down by Marine Creek, and through the newer developments east of the lake. Our reviews mention the same three things: the price didn’t move, the crew showed up in uniform and on time, and any issue after close-out got handled under the 365-Day Done Right Promise. Troy Eastman, who leads Benson ADU Fort Worth, insists on that from every project. A live person answers our phones around the clock, not a voicemail tree.
Working with Lake Worth homes means understanding what’s under them. Slab-on-grade ranches from the 1950s to 1970s have their own plumbing personalities. Pier-and-beam homes have theirs. We scope both before quoting, and that local knowledge is exactly why homeowners on both sides of the lake choose us over a contractor from Dallas who’s never dealt with colluvium soils shifting a foundation line.
Sunroom Builders in Lake Worth
Sunroom Builders in Lake Worth handle a particular challenge here: hot, humid summers that punish cheap glazing. A properly built sunroom on a Lake Worth home needs tempered or laminated glass with a low-E coating, a mini-split sized for the room’s orientation, and flashing that holds up to the spring and fall storm lines that roll across Eagle Mountain Lake. Most sunrooms in Lake Worth run $145 – $225 per square foot, with three-season rooms at the lower end and four-season conditioned rooms at the upper end.
Foundation and tie-in work
A sunroom addition on a slab home usually means saw-cutting the existing slab edge and doweling in new rebar, then pouring a matched slab. On pier-and-beam, we level the existing perimeter beam before adding new piers at the same depth. Skipping that step causes the sunroom to settle away from the house within two years.
Glazing and HVAC choices
Lake Worth humidity drives the glass decision. We spec insulated units with the low-E coating facing the right direction for our climate, and most sunrooms here get a dedicated ductless mini-split rather than a tied-to-the-main-system register run that never keeps up in August. The written quote includes both the glazing specs and the cooling load calculation.
Room Additions in Lake Worth
Room Additions in Lake Worth range from a 14×16 primary suite bump-out to a full wing with a bathroom, walk-in closet, and laundry. The work means cutting into the existing roofline, matching your current pitch, tying foundation properly, and extending mechanicals. Most single-room additions here land between $48,000 and $96,000. Adding a bathroom pushes toward the higher end because of plumbing and a likely sewer line review.
Sewer scope before framing
Before we frame a room addition with a bath or kitchen on a mid-century slab home, we run a sewer camera down the existing line. That $300 – $500 inspection catches offsets and cracks in original cast iron before they become a $4,000 tear-out after the city inspector refuses to sign off on the rough-in.
Roof tie-in and drainage
A flat or low-slope section on your existing roof changes how we flash the addition. On Lake Worth homes with composition shingles, we do a full section tear-in rather than a patch job so the seam doesn’t leak during one of our heavy spring downpours. Drainage gets scoped at the same visit: swales, downspout extensions, and grading away from the new foundation line.
Trusted Brands We Service in Lake Worth
Benson ADU Fort Worth builds with Dvele’s high-performance panelized systems and Mighty Buildings’ prefab wall assemblies, plus Boxabl for detached units when the lot and access allow. What that means for Lake Worth customers is faster framing on site and materials that arrive pre-cut to spec, which matters when your driveway off a county road can’t handle a dozen lumber drop-offs. We stock common trim, flashing, and tie-down parts for these systems locally, so if a piece gets damaged during a burn ban wind event, you’re not waiting two weeks on a replacement part. Troy Eastman’s team walks you through which brand fits your addition before you ever sign.
Common Room Addition Contractor Problems We See in Lake Worth Homes
- County permit gaps on acreage lots: A homeowner assumes Lake Worth city permits cover the addition, then a Tarrant County inspector shows up and flags setbacks the plans never addressed. We verify jurisdiction first, before you pay for drawings that won’t pass.
- Septic and well setbacks forcing redesigns: Adding a bathroom or kitchen on a large lot means the drain field and well location dictate where the addition can sit. When nobody checks that early, homeowners pour a foundation and then fail the county health inspection, which means relocating the entire addition.
- Long hauls and torn-up yards: Unpaved county road access or a 400-foot driveway off Ten Mile Azle Road means heavy trucks need a plan, not improvisation. We schedule material drops with equipment the access road can actually handle, so your yard doesn’t become a mud pit before framing starts.
- Hidden cast-iron offsets under slabs: Original sewer lines on 1960s ranches shift over time. The offset only shows itself when a second bathroom or laundry goes in, and by then the rough plumbing is already installed. A camera scope before framing costs a few hundred dollars and prevents a four- or five-figure change order.

FAQs About Room Addition Contractor in Lake Worth
It depends on whether your property sits inside Lake Worth city limits or in unincorporated Tarrant County. Inside the city, you’ll pull through Lake Worth’s building department. On acreage outside the city, Tarrant County permits govern the work, and the setbacks and inspection timelines differ from city code. We check your parcel before quoting so the permit path is correct from day one. Call (682) 204-9686 and we’ll verify your property during the free estimate.
Your existing drain field and well head create fixed exclusion zones that a room addition cannot encroach on, and Tarrant County enforces those setbacks strictly. On a one-acre lot with a traditional drain field, that often pushes an addition toward the front or side of the home rather than the rear. We pull your county health records during the scoping phase and mark the setbacks on the plan before any foundation work is quoted. Call (682) 204-9686 to have your lot assessed.
Most flat lots in Lake Worth need a combination of regrading around the new foundation, French drains along the tie-in edge, and sometimes a swale if the neighboring lots sheet water your way during heavy thunderstorms. We include drainage scope in every written quote, typically $2,000 – $6,000 depending on the slope and soil. It’s cheaper to plan drainage with the foundation than to retrofit it after the first big spring storm. Call (682) 204-9686 for a drainage line-item specific to your yard.
Because original cast-iron lines under mid-century slabs in Lake Worth often have offsets from decades of soil movement, and those offsets only become visible when a second bathroom or laundry adds flow to the line. A camera scope costs $300 – $500 and shows the condition before you invest in framing. If we find an offset, we price the spot repair into the quote instead of surprising you mid-project. Call (682) 204-9686 and ask for a scope on your free estimate visit.
It changes everything, because the build site is farther from the road, usually down a long driveway or unpaved county access. Delivery trucks, concrete pumps, and a mini excavator all need a stable path, and on wet Lake Worth springs, that often means scheduling gravel or using smaller staged deliveries to keep your yard passable. We account for that in the written quote, including $800 – $2,500 for access prep on hard-to-reach lots. Call (682) 204-9686 and we’ll walk the access route with you before quoting.
