Custom Fireplace Mantel & TV Feature Wall in World Golf Village, St. Augustine FL

The Project

When a homeowner in World Golf Village reached out to AVP Construction JAX, they had a very specific vision: take a completely bare corner of their living space in St. Augustine, Florida and turn it into a warm, traditional focal point — something that felt like it had always belonged there. They wanted a place to mount their TV, but more than that, they wanted the cozy, classic feel of a fireplace mantel. The result is one of our favorite builds in St. John's County: a full floor-to-ceiling feature wall with vertical board paneling, a hand-crafted traditional fireplace surround, a checkerboard tile hearth, and an electric fireplace insert — all finished in a rich, dark warm-gray that anchors the entire room.

The Challenge

The starting point was as blank as it gets. As you can see in the before photo, the corner walls were flat white drywall with nothing to work with — no ledge, no niche, no architectural detail of any kind. There wasn't even a practical wall to mount a TV on without it looking stranded in space. The homeowner wanted a traditional fireplace aesthetic, but the home had no gas line and no existing firebox. Everything — the structural build-out, the paneling surface, the mantel, the tile surround, and all the finish work — had to be created from the ground up in that corner.

Building into a corner also meant the framing had to be precisely plumb and square on two planes simultaneously so that the finished wall would read as a single cohesive feature rather than two walls awkwardly meeting. Getting the depth right for the fireplace insert pocket while keeping the overall profile tight to the room was the kind of detail that separates a carpentry build from a furniture store purchase.

The Build

We started by framing out the corner. In this build photo you can see the clean lumber skeleton — vertical and horizontal members creating a pocket for the electric fireplace insert at the base, with the full-height frame establishing exactly where the paneling surface would live. The framing needed to be dead-plumb so every vertical board above it would hang true all the way to the crown.

With the framing solid, we installed vertical tongue-and-groove style boards across the entire face of the feature wall, running them floor to crown. This gives the wall that classic board-and-batten / vertical plank look that pairs so well with a traditional mantel. You can see in this during photo — with the wall primed white and nail holes still fresh — just how much coverage and architectural presence the paneling creates even before a drop of finish color goes on. A substantial crown molding profile caps the top edge, tying the whole panel into the ceiling line.

Meanwhile, back at our Jacksonville shop, the fireplace mantel surround was taking shape. We built it as a traditional-style surround — thick tapered legs, a bold header with layered molding profiles, and a proper mantel shelf with returns. You can see the raw pine construction in the shop photo: every joint is tight, the proportions are classic without being heavy, and the corbel details at the header corners give it that period-appropriate character. This isn't a box with trim glued on — it's a proper mantel built the way they were built a hundred years ago.

Once the wall was painted in its final deep warm-charcoal tone and the mantel was ready for its finish, we applied a rich dark stain to the surround right on-site, working in the driveway to let each coat breathe before installation. That stained mantel against the dark painted wall creates a tonal layering that reads as sophisticated and intentional — you see the texture of the wood grain through the color, which keeps it from feeling flat. The checkerboard tile in muted sage green and warm white was set into the firebox opening as the hearth surround, adding a playful, slightly vintage note that works beautifully with the traditional mantel legs flanking it.

The electric fireplace insert was set into the framed pocket at the base, wired to the existing outlet, and the TV was wall-mounted above on a bracket anchored into the structural framing behind the paneling — no wobble, no visible wires, just a clean floating screen above the mantel shelf.

The Result

The finished feature wall stopped being a corner the moment we were done. What was a forgettable blank space in this World Golf Village home is now the undeniable focal point of the room — a tall, dark, richly detailed wall that draws your eye the instant you walk in. The vertical planking catches the light differently depending on the time of day. The stained mantel surround glows against the dark paint. The checkerboard tile hearth gives the whole composition a personality. And the large-format TV mounted above looks completely at home rather than like an afterthought bolted to drywall.

Sitting in that room with the electric fireplace flickering and the TV on above the mantel, you'd never guess the entire thing was a bare corner twelve months ago. This is exactly the kind of transformation we love doing in St. Augustine — taking a builder-grade blank slate and giving it the kind of custom millwork detail that makes a house feel like a home.
