5. Architectural Plaster Arched Sconce
Introduction A sculptural wall sconce that integrates seamlessly into drywall, creating a built-in, Mediterranean alcove aesthetic using basic foam board and joint compound.
What This Idea Means This approach mimics custom high-end plasterwork found in European boutique hotels. It uses plaster textures to turn the light source into an architectural feature that blends directly with the wall.
How to Make It
- Cut high-density foam board into a classic arch silhouette with two tiered side-retaining walls that project 4 inches from the wall.
- Glue the components together using strong construction adhesive to form a hollow back-less hood.
- Coat the entire structure with two to three layers of lightweight joint compound or Venetian plaster, sanding lightly between coats for a matte stone finish.
- Install a wireless, rechargeable warm-glow LED tap puck onto the wall, and hang the plaster arch directly over it using French cleats.
Tips & Variations
- Textured Stucco: Use a coarse sponge during the final compound coat for an earthy, rough-hewn clay texture.
- Limewash Finish: Paint with beige or sand-toned limewash to create depth and visual movement.
- Fluted Arch: Line the face of the arch with half-round wooden dowels before plastering for a ribbed texture.
