Why Groundwork Construction Co. of South Florida Is Country Walk’s Preferred Home Additions & ADU Company
We’ve worked in Country Walk long enough to know which homes are original late-1970s CBS construction and which were rebuilt after Hurricane Andrew tore through in August 1992. That distinction matters more here than almost anywhere else in South Florida. Our crew has navigated Miami-Dade’s High-Velocity Hurricane Zone permitting on dozens of Country Walk properties, and we know the inspectors by name - not because we cut corners, but because we show up with the right hardware schedules and structural details the first time.
Homeowners in Country Walk choose us because we’re a single-source contractor. You don’t need a separate designer, a separate permit runner, and a separate foundation crew. We handle ADU design and permitting, garage conversions, room additions, and second-story builds under one contract with one point of accountability. Raymond Estevez, who leads Groundwork, reviews every Country Walk project personally before it hits the permit desk.
Our response time to Country Walk is typically same-day for consultations, and we keep a rolling schedule open for Miami-Dade permit expediting. We’ve learned that in this market, speed without accuracy costs more than patience with precision.
Our Home Additions & ADU Services in Country Walk
ADU Design & Permitting
Every ADU in Country Walk starts with a site analysis that most contractors skip. We check your existing roof-to-wall connections, your slab thickness, and your proximity to the community’s drainage canals before we draw a single line. Miami-Dade’s HVHZ code requires Miami-Dade County Product Approval on all structural components, and we spec those from day one. Our permitting package includes the hurricane clip schedule, the sheathing nail pattern, and the wind-load calculations that Country Walk inspectors expect to see. We’ve had permit applications approved in 6 weeks and we’ve seen competitors’ applications rejected twice for missing H2.5A clip details on pre-Andrew homes. The difference is in the prep.

Garage Conversion ADU
Garage conversions are the most common ADU request we get in Country Walk, and they’re also the most likely to hit surprises. We recently converted a garage into a junior ADU on a pre-Andrew CBS home near the Country Walk community center. The existing slab was only 3.5 inches thick and un-reinforced, so we had to cut a new 12-inch-deep footing into the oolitic limestone - using a jackhammer - to meet Miami-Dade’s HVHZ requirements for the new ADU. We also upgraded the original rafter tails with Simpson H2.5A clips, which the inspector flagged before we even tied into the roof deck. That project came in at $47,000, and the homeowner now has a permitted 420-square-foot rental unit.

New Detached ADU
Detached ADUs in Country Walk give you the most design freedom and the fewest structural entanglements with your existing home. We build these stick-framed or with prefab units from Abodu, Dvele, Mighty Buildings, or Boxabl, depending on your timeline and budget. The catch is always the foundation. Country Walk’s shallow Miami rock means standard post-hole diggers stop dead at 14 inches. We price rotary or jackhammer excavation into every detached ADU quote for this area. A typical 600-square-foot detached ADU in Country Walk runs $110,000-$180,000, with foundation work representing 15-20% of that total.

Junior ADU & Interior Conversion
Junior ADUs work well in Country Walk’s larger post-1992 rebuilds, where the original floor plans included flexible spaces that can be partitioned with independent exterior access. We handle the interior framing, the separate electrical meter coordination with FPL, and the kitchenette rough-in. In pre-Andrew homes, we often need to upgrade the electrical service panel to 200 amps to support the additional dwelling unit. That’s a $3,500-$6,000 line item that we identify during our first walkthrough, not after drywall is up.

Room Additions
Room additions in Country Walk - whether it’s a master suite expansion, a family room bump-out, or a home office - require the same structural scrutiny as ADUs. The roof tie-in is where most projects stumble. Pre-Andrew homes often have 2×4 rafters with minimal overhang and no hurricane straps. Miami-Dade inspectors will reject any addition that doesn’t upgrade every existing rafter tail within the connection zone. We build that upgrade into our scope and our price from the start. A 300-square-foot room addition on a Country Walk home typically runs $65,000-$95,000, including structural upgrades.

Trusted Brands We Service in Country Walk
We don’t lock Country Walk homeowners into proprietary products. You choose the brand, we handle the build. For ADU and addition cabinetry, we work with KraftMaid and Wellborn across multiple price tiers. Countertops draw from Cambria, Silestone, and Caesarstone. Exterior cladding on additions often spec James Hardie fiber-cement siding for its HVHZ approval rating and impact resistance. Our roofing materials come from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - each with their own material warranties that transfer to you. We stock common hardware like Simpson hurricane clips and Miami-Dade-approved fasteners locally, so we’re not waiting on supply house deliveries when your inspector shows up.
Common Home Additions & ADU Problems We See in Country Walk Homes
- Permit delays when pre-Andrew homes lack hurricane clips. Miami-Dade inspectors routinely fail addition work that would pass in Broward County. We see this on at least half the pre-1992 homes we touch in Country Walk. The fix is straightforward - Simpson H2.5A or stronger at every rafter tail - but it adds $2,500-$5,000 and a week of labor that wasn’t in the original homeowner’s budget.
- Foundation excavation hitting shallow Miami rock. The oolitic limestone under Country Walk sits 12-18 inches down in most lots. Standard excavation equipment won’t touch it. We budget for rotary hammer or jackhammer work on every foundation job, and we warn homeowners that “soft dig” assumptions from out-of-area contractors will blow up their budget.
- Mismatched structural standards creating weak points. Attaching a new HVHZ-compliant addition to a pre-Andrew CBS shell without properly connecting the roof-to-wall load path creates a failure point that inspectors spot immediately. We’ve had to demolish and rebuild connection details on competitor projects that skipped this analysis.
- High water table complicating drainage and utility runs. Country Walk’s position at the eastern edge of the Everglades means seasonal water tables that can flood open trenches. We spec French drains and raised utility connections on ADU projects that inland contractors wouldn’t anticipate.
Pricing for Home Additions & ADU in Country Walk, FL
Here’s what we’re seeing for Country Walk projects in 2025-2026. These ranges reflect the HVHZ structural upgrades and limestone foundation work that this market demands:
| Project Type | Typical Range in Country Walk |

| ADU Construction (detached) | $90,000-$220,000 |
| Home Addition (room or bump-out) | $45,000-$130,000 |
What moves you within these ranges? Foundation conditions are the biggest variable - jackhammering through Miami rock adds $4,000-$12,000 compared to standard diggable soil. Pre-Andrew structural upgrades add $2,500-$8,000 depending on roof complexity. Finish level moves the needle too: KraftMaid semi-custom cabinetry versus Wellborn’s full-custom line can swing a kitchen-equipped ADU by $8,000-$15,000. We don’t guess. Our estimates are free, detailed, and itemized, so you see where every dollar goes before you sign. Call (844) 665-0162 to schedule.

FAQs - Home Additions & ADU in Country Walk
Your garage conversion must meet Miami-Dade’s High-Velocity Hurricane Zone standards, which include Miami-Dade County Product Approval on all structural components, hurricane clips or straps at every rafter tail, and impact-rated openings if the ADU is within the envelope of the existing structure. On pre-Andrew homes, inspectors will require upgrades to existing roof-to-wall connections as a condition of permit approval. We build these requirements into our design phase so your plans pass the first time. Call (844) 665-0162 and we’ll review your specific home’s structural status.
Yes, but it requires a full structural analysis and typically involves reinforcing or replacing the existing foundation, upgrading the load-bearing walls, and installing continuous hurricane straps from foundation to ridge. Pre-Andrew CBS homes in Country Walk were built with 3.5-inch slabs and minimal rebar, so the foundation rarely supports a second story without significant intervention. We bring in a structural engineer early in the process to determine whether it’s more practical to add a second story or to build a detached ADU instead. For a free feasibility assessment, call (844) 665-0162.
The most common reason is inadequate roof-to-wall connection details on pre-Andrew homes. Miami-Dade inspectors in the HVHZ enforce stricter hardware schedules than anywhere else in Florida, and they will reject work that lacks documented hurricane clips, proper sheathing nail spacing, or Miami-Dade-approved product labels. We’ve also seen rejections for foundation details that don’t account for Country Walk’s high water table or limestone substrate. Our permitting package includes every detail the inspector expects, because we’ve been through their checklist dozens of times. If you’re stuck in a rejection loop, call (844) 665-0162 - we can review your existing plans and identify the fix.
A detached ADU in Country Walk typically costs $90,000-$220,000, with foundation work representing 15-20% of the total. The shallow Miami oolitic limestone means standard excavation stops at 12-18 inches, forcing us to use rotary or jackhammer methods for footings and drainage. That adds $4,000-$12,000 compared to diggable soil, but it’s non-negotiable for a permitted foundation. We include this in our upfront estimate, not as a surprise change order. For an exact quote on your lot, call (844) 665-0162 - estimates are free.
Yes, if your home was built before 1992. Miami-Dade inspectors require hurricane clips or straps at every rafter tail within the connection zone of any new addition, and they will flag inadequate existing connections on the original structure. This applies to sunrooms, enclosed patios, and any roofed addition. The upgrade typically costs $2,500-$5,000 and adds 3-5 days to the framing schedule. We identify this requirement during our initial site visit so it’s in your contract from day one. Call (844) 665-0162 to schedule that visit.
