Adding an Arch to an Existing Walkway
Arched openings can completely change the feel of a space. They soften transitions between rooms, add architectural character, and make a home feel more custom without changing the layout.
Most people assume arches are something that has to be designed when the house is built, but that’s not always the case. Recently we helped a homeowner add an arch to an existing walkway that already had finished drywall on both sides.
Because the wall was already finished, the process was a little different than building an arch during new construction.
Working with an already finished opening
When a walkway already has drywall installed, you can’t simply cut the curve and be done. The drywall edges would be rough, the framing wouldn’t support the shape properly, and it would be difficult to get a smooth transition.
Instead, we built the arch structure first.
We constructed the curved arch pieces that would form the shape of the opening and installed them on both sides of the existing drywall. This creates the structure for the arch while keeping the opening clean and symmetrical.
Building the arch without shrinking the space too much
One concern homeowners often have is that adding an arch will make the opening feel much shorter or smaller.
To avoid that, the curve has to be designed carefully. The goal is to soften the top of the opening without dramatically lowering the height. In this case, we shaped the arch so it created a smooth curve while still maintaining the openness of the walkway.
When done correctly, the change feels natural rather than noticeable.
Installing drywall to form the curve
Once the arch structure was in place, we installed new drywall pieces to form the curved underside of the opening. Curved drywall work takes a bit of patience because the material has to be shaped carefully so it follows the arc smoothly.
After that, the joints were taped and mudded so the new drywall blended seamlessly into the existing wall.
Making the transition look original
The final step is where the real detail work happens. The drywall compound is built up and sanded so the transition from the wall into the curve feels smooth and continuous.
When the work is done properly, the arch shouldn’t look like something that was “added on.” It should look like it was always part of the home.
This is where careful mud work and finishing make all the difference.
A small change that makes a big difference
Architectural details like arches can transform a plain hallway or walkway into something that feels more intentional and finished. It’s a relatively small modification, but it can add character to a space that previously felt very square and basic.
