This project was built and designed by Marcus from Salty Woodworking. It’s the first phase of a built-in entertainment center featuring a fireplace, floating shelves, and custom cabinetry.
Marcus starts by converting a blank wall into a structured framework using stud markings and a laser level. The design is mapped in Fusion 360 to streamline measurements and ensure accuracy during the build.

Laying Out the Foundation
Stud locations are marked to prepare for framing, with a laser level helping keep lines true. Tools are staged nearby to minimize back-and-forth, and the floor becomes a practical workspace.
Using Fusion 360, Marcus lays out the entertainment center’s dimensions before cutting. This planning stage saves time and reduces errors throughout the project.
Framing Lessons and Adjustments
Initial framing with Phillips screws led to stripping issues and delays. Switching to a framing nailer sped up the process and improved efficiency.
Removing crown molding was necessary for a snug fit and room for shiplap. After a bit of trial and error, the molding went back in with a clean, finished look.
Building the Fireplace Wall
The center structure includes space for the electric fireplace and TV mount. A minor miscalculation in height was corrected quickly, showing how flexibility is key during installation.
The original plan called for an overly deep recess for the mount, which was later adjusted. A depth of just two inches worked perfectly while keeping the mount secure.
Installing the Touchstone Fireplace
The electric fireplace was mounted easily and adds warmth and modern appeal. It’s secured with screws and sits flush with the structure.
Marcus selected a log insert for a traditional look. The fireplace features multiple control options, including Wi-Fi integration for remote operation.
Wrapping Up Phase One
To finish this phase, the crown molding was caulked, and the entire unit received a fresh coat of white paint. Though not filmed, the painting step helped unify the whole installation.
With framing and fireplace work complete, Marcus will move on to the mantel and cabinetry in part two. The project is already shaping up to be a standout feature for the home.

Matt’s Take
These are my personal thoughts and tips based on my own experience in the shop. This section is not written, reviewed, or endorsed by the original creator of this project.
Marcus tackled this project with smart planning that really shows. Using Fusion 360 for layout before making cuts is something more of us should embrace — it catches those measurement mistakes before they turn into expensive lumber. That laser level for keeping everything plumb is crucial too, especially on a project this size where small errors compound quickly.
The switch from Phillips screws to a framing nailer is a lesson many of us learn the hard way. Those thin screw heads strip out fast when you’re driving into framing lumber, and a nailer just powers through without the frustration. For anyone considering a similar built-in, having that nailer will save hours of work and plenty of stripped fasteners.
That minor height miscalculation Marcus had to correct is totally normal on custom work like this. Built-ins rarely go exactly to plan, and being able to adapt on the fly is part of the skill. The two-inch TV mount depth he settled on is actually perfect — gives you enough room for cables without creating an unnecessarily deep cavity that eats into your wall space.
Electric fireplaces have come a long way in terms of looks and functionality. The Wi-Fi control feature is pretty slick for a built-in application where you might not want to walk over to adjust settings manually.
