Dvele Home Additions & ADU: The West Palm Beach Owner’s Guide
If you own a Dvele home in West Palm Beach and are planning an addition or ADU, you’re looking at an installed price range of $45,000 – $130,000 for a home addition, and $90,000 – $220,000 for a detached ADU. We install Dvele-compatible additions and accessory dwelling units throughout West Palm Beach, and we carry the panelized components, connection hardware, and finish materials this work requires. Most Dvele owners call us when they’ve outgrown their current footprint: a second child arrives, an aging parent moves in, or a home office suddenly needs to be a permanent room rather than a corner of the dining table.
The conversation usually starts with a question about whether a Dvele home can even be extended. The answer is yes, but it’s not a conventional stick-frame addition. Dvele homes are built around a specific panelized system, and the addition needs to match those connection points, dimensions, and material tolerances. That’s where we come in.
Before anything gets ordered, Graham Stein walks the site himself. He checks the existing Dvele connection details, verifies what the foundation can carry, and puts a written scope of work in your hands. Itemized labor, materials by brand and quantity, and a firm start and end window. Put it in writing, then do exactly that.
Key Takeaways:
– Dvele additions and ADUs in West Palm Beach run $45,000 – $130,000 for attached additions and $90,000 – $220,000 for detached ADUs
– Dvele’s panelized system means the addition must match specific connection points and dimensions – this is not a generic stick-frame job
– We provide a written price before any work starts, every time
– The 365-Day Done Right Promise covers every completed project: if it’s not done right, we make it right
Which Dvele Models This Applies To
Dvele builds homes around a proprietary panelized construction system rather than conventional site-built framing. That means the walls, floor cassettes, and roof panels arrive on-site with connection hardware already engineered into them. Any addition or ADU has to match that system, and that’s where a lot of contractors in West Palm Beach get into trouble. They treat a Dvele home like a stick-built house, frame the addition conventionally, and end up with mismatched wall depths, awkward transitions, and a marriage line that leaks or settles differently over time.
The most common Dvele configurations we work with in West Palm Beach include their single-story and two-story panelized homes, which feature wall panels that are typically thicker than standard 2×4 or 2×6 framing. Before we order anything, we verify the specific panel dimensions on your home, locate the existing connection points, and confirm the foundation type. Homes on slab foundations require a different tie-in approach than homes on raised piers.
The OEM-versus-aftermarket decision matters here. Dvele’s original components carry manufacturer warranties and are engineered to match your existing structure exactly. For structural elements like wall panels and roof cassettes, we recommend staying with Dvele-spec materials. For finish work inside the addition, cabinets, countertops, and fixtures, you have real choices. We work with KraftMaid and Wellborn cabinets, Cambria and Silestone countertops, and Kohler, Moen, and Grohe fixtures. Those are brands you can research by name, and their warranties travel with the finished project.

Signs Your Dvele Home Additions & ADU Is Failing
If you already have a Dvele addition or ADU, these are the symptoms we see most often in West Palm Beach before a homeowner calls us:
- Visible separation at the tie-in line. The seam where the addition meets the original structure develops a visible gap or crack. This usually means the connection hardware wasn’t installed to Dvele spec, or the two structures are settling at different rates in Florida’s sandy soil. In neighborhoods like Flamingo Park, where groundwater and soil movement are real factors, this is the single most common call we get.
- Humidity or condensation inside the ADU. Florida’s humidity will find any gap in the building envelope. If the addition feels clammy or you’re seeing moisture on interior walls, the vapor barrier or panel seals may not be continuous. Dvele homes are designed around a tight envelope, and a poorly executed tie-in breaks that seal.
- Uneven floors at the transition point. A slight step or slope where the new floor meets the original one signals foundation movement or an improper floor cassette connection. This is a structural issue that worsens over time and should be evaluated by someone who understands panelized construction.
- Doors or windows that stick seasonally. This indicates the addition is moving independently of the main house. In West Palm Beach’s wet-dry seasonal cycles, soil expands and contracts, and a poorly tied addition will flex at the connection points.
- HVAC imbalance. The addition never quite gets to the same temperature as the rest of the house, or the system runs constantly. This points to undersized ductwork or a building envelope that wasn’t sealed properly at the tie-in, often because the addition’s thermal boundary doesn’t match the Dvele original.

AfterReplacement Cost & What’s Included
For West Palm Beach homeowners, here’s what you can expect on price:
| Project Type | Installed Price Range |
|---|---|
| Attached Home Addition (Dvele-compatible) | $45,000 – $130,000 |
| Detached ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
What drives the range is square footage, foundation work, and how much of the existing Dvele structure has to be opened up at the tie-in. A smaller addition with a simple slab extension and minimal electrical work lands near the bottom. A full ADU with a kitchen, bathroom, and separate utility connections lands near the top.
Every project includes a written line-item price before any work starts: materials by brand and quantity, labor broken out, and a firm start and end window. Drop cloths on the floors and shoe covers at the door are included on every job, not charged as an add-on. When the crew leaves, you get a photo of the clean-up as proof the home was left right. And the 365-Day Done Right Promise covers the completed project, if anything isn’t done right, we make it right.
DIY or Call Us?
An addition or ADU is not a DIY project, and we’d say that even if we weren’t the ones doing the work. The structural connection between a Dvele panelized home and any new construction involves load calculations, foundation engineering, and connection hardware that has to be installed to manufacturer spec. Get that wrong and you’re not looking at a cosmetic fix, you’re looking at a structural failure. In West Palm Beach, hurricane code requirements add another layer: any addition must meet current wind-load standards, and permits have to be pulled and inspections passed.
What you can do yourself is plan. Walk your property, look at setback requirements, think through how the addition connects to your roofline, and write down what you actually need from the space. That prep work helps the first estimate conversation move faster.
If you already have a Dvele addition that’s showing separation, moisture, or movement, don’t wait. Those symptoms don’t fix themselves, and they get more expensive the longer they sit. Call (728) 203-3270 and we’ll schedule a walkthrough. Graham still visits every job site himself before a single drop cloth goes down.
FAQs
How long does a Dvele home addition or ADU last?
A properly executed Dvele-compatible addition should last the life of the original structure, 50 years or more. The longevity depends on two things: whether the tie-in was done to Dvele’s connection spec, and whether the building envelope was sealed continuously. In West Palm Beach’s humidity, the envelope matters as much as the structure. Call (728) 203-3270 for an inspection if your addition is showing its age.
Can you repair a failing Dvele addition instead of rebuilding it?
In many cases, yes. We can often address tie-in separation, envelope gaps, and settlement without tearing down the addition. The repair path depends on what we find when we open the connection point, and we’ll only know that once we’re in there. Call (728) 203-3270 and we’ll give you a straight answer after a site visit.
How long does the work take?
A straightforward attached addition typically runs 4 to 8 weeks from permit to final walkthrough. A full ADU with a kitchen and bath can run 3 to 5 months. We give you a written start and end window before anything starts, and we hold to it. Call (728) 203-3270 to schedule your free estimate.
Do you stock Dvele-compatible parts and materials?
We don’t warehouse Dvele panels on a shelf, but we order Dvele-spec components directly for every project, and we carry the connection hardware and finish materials that go with them. For cabinetry, countertops, and fixtures, we also work with KraftMaid, Cambria, and Silestone. Call (728) 203-3270 for an exact quote, estimates are free.
