Why Rowan Construction Group West Palm Beach Is Wellington’s Preferred Home Additions & ADU Company

We’ve built and converted in Wellington long enough to know the difference between a Paddock Park slab pour and a Preserve estate footing. That matters when your addition sits on land where the water table can reach within 12-18 inches of grade.

Our Wellington customers find us the same way they research appliances - they read the three-star reviews, then call to see if we’ll put a number in writing. We do. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Every time. Across 4,000-plus projects, our final invoices have stayed within a few percent of that written number because no change proceeds without a signed change order.

Our crews are background-checked and uniformed. Every visit produces a documented photo record included as standard, not an upgrade. And our 365-Day Done Right Promise is printed on every page, backed by a terms page, not an asterisk.

Our Home Additions & ADU Services in Wellington

ADU Design & Permitting

Wellington’s Equestrian Preserve Area zoning does not just govern barns and arenas - it restricts subdivision and mandates equestrian-compatible land use, so adding an ADU or second-story addition inside the Preserve frequently turns on whether the new square footage reads as an accessory dwelling for family or caretakers rather than a second residential unit, a distinction that simply does not exist in Royal Palm Beach or Greenacres. We handle that zoning analysis upfront, before design hours are spent. Our ADU design and permitting service in Wellington includes site plan review, drainage compliance given the area’s high water table, and permit package preparation that accounts for whether your lot sits in the Preserve or in standard residential zoning. A typical detached ADU in Wellington runs $90,000-$220,000.

Garage Conversion ADU

In Olympia, we converted a 55+ homeowner’s original tub-and-shower combo into a zero-threshold walk-in shower with backing installed for future grab bars, then widened the hall doorway to 36 inches and swapped the vanity for a Kohler comfort-height model with Silestone top to keep the space slip-rated and low-maintenance. The same client’s seasonal residency meant we scheduled the rough-in and inspection sign-off during the summer months so the punch list was closed before they returned. We also set the exterior approach with slip-rated pavers and a single-level threshold because the slab sat high on Wellington’s water table. Garage conversions in Wellington typically cost $30,000-$80,000 and always require permits - skipping inspection sign-off surfaces later when a future buyer’s lender demands closed permits for the added living area.

New Detached ADU

Detached ADUs in Wellington face unique site challenges. The flat, low-lying land adjacent to the Everglades Water Conservation Areas means slab and footing design must account for hydrostatic pressure that doesn’t exist in West Palm Beach’s higher coastal ridges. We specify vapor barriers, perimeter drains, and finished floor elevations that keep living space above seasonal groundwater. For Preserve-area estates, we design ADUs that read as caretaker quarters or guest housing under equestrian-compatible use rules, with separate utility metering where required. New detached ADU construction in Wellington starts around $90,000 and ranges to $220,000 depending on size, finish level, and site complexity.

Junior ADU & Interior Conversion

Junior ADUs - converted within the existing footprint, often from a master suite reconfiguration or attached garage - work well in Wellington’s 55+ communities where aging-in-place needs outpace the desire to relocate. We design for future grab-bar blocking, 36-inch doorways, and single-level living even when the original home has split plans. Interior conversions in Wellington’s CBS construction require careful evaluation of load-bearing walls; we identify structural modifications during the written quote phase so the price you sign reflects the actual framing, not a cosmetic assumption. Bathroom remodels tied to these conversions typically run $9,000-$28,000, with walk-in shower installations at $4,500-$12,000.

Room Additions

Room additions in Wellington’s HOA subdivisions face architectural review boards with specific material and design guidelines, while Preserve-area additions must maintain equestrian-compatible character. We navigate both. Our room addition process starts with a site evaluation that includes drainage planning - critical in Wellington where improper grading on new slab work produces chronic standing water that homeowners fight for years. A typical room addition in Wellington costs $45,000-$130,000 depending on square footage, foundation type, and finish specifications.

Trusted Brands We Service in Wellington

We source across fifty-plus vetted brands so the written quote carries honest numbers rather than inflated ones. For Wellington’s aging-in-place and ADU projects, we regularly specify Kohler comfort-height fixtures and Moen grab-bar-ready valve systems, with Caesarstone or Silestone surfaces for low-maintenance, slip-rated bath environments. Blanco silgranit sinks hold up well in seasonal residences where kitchens sit unused for months. We stock common configurations locally for faster turnaround on replacement and repair phases, and our relationships with these manufacturers mean warranty claims route through us, not the homeowner.

Common Home Additions & ADU Problems We See in Wellington Homes

• Chronic standing water beneath new slab work. Wellington’s water table sits 12-18 inches below grade in many areas. Skipping drainage and site-grading review on ADU slab pours leads to moisture intrusion that destroys flooring and breeds mold. We specify perimeter drains and vapor barriers as standard, not as change orders.
• Unpermitted garage conversions surfacing at sale. Treating a garage conversion or junior ADU as cosmetic and skipping permits creates a title defect. Future buyers’ lenders require closed permits for added living area. We pull permits on every job, schedule inspections, and deliver signed-off documentation.
• Mid-construction change orders for aging-in-place features. Designing additions without advance blocking for grab bars or load-bearing wall analysis forces reframing when the zero-threshold shower or widened doorway won’t fit the existing structure. We identify these requirements in the written scope before work starts.
• Winter Equestrian Festival timing failures. Wellington’s January-April influx of seasonal residents means permits and subcontractors for additions and ADU work must be locked before November. Contractors who miss this window lose the season to competitors who planned ahead. We schedule Wellington projects with this calendar in mind.
