Building a Plasterboard Pillar for an Electrical Point: From Framing to Flawless Finish

When it comes to home renovations, sometimes the most functional elements can also become statement features. Recently, a customer approached us needing a new electrical point on their kitchen benchtop, but there was no wall nearby to support it. The solution? A custom-built plasterboard pillar, running from ceiling to benchtop. In this post, we’ll walk you through how we framed the internal structure with hardwood, applied plasterboard, completed plastering, and finished with skirting to create a seamless, eye‑catching pillar that’s both practical and beautiful.

1. Understanding the Requirement

The project began with a clear functional need: the homeowner wanted an electrical outlet conveniently located above their benchtop for small appliances like a toaster and coffee machine. Because there was no existing wall in the right spot, we needed to build a freestanding support—a plasterboard pillar—that would house the wiring safely and look like a planned architectural feature.

Key points to consider:

• Pillar location and alignment (to match ceiling joists and benchtop edge)
• Adequate space inside for electrical conduits and junction box
• Structural rigidity to support the weight of the plasterboard and skirting

2. Framing the Internal Structure with Hardwood

Rather than using metal studs, we opted for hardwood (typically treated pine) for its strength and ease of on‑site modification. Here’s how we constructed the frame:

1. Marking and Measuring
   We carefully measured the distance from ceiling to benchtop and marked the exact position on both surfaces. Precision here ensures the pillar is perfectly vertical and stable.
2. Cutting the Hardwood Studs
   Hardwood pieces were cut to length. Two main side studs run the full height, with horizontal blocking at top, bottom, and mid‑height to prevent twisting and to provide surfaces for screw attachment.
3. Securing the Frame
   • Top Plate: We attached a small top plate to the ceiling joists with heavy‑duty screws and brackets.
   • Bottom Plate: A matching bottom plate was fixed to the benchtop support structure.
   • Bracing: Cross‑braces and blocking were installed midway to stiffen the assembly and create nailing surfaces for the plasterboard.

This hardwood skeleton provides a rock‑solid backbone for the plasterboard, ensuring there’s no flex that could crack the surface later.

3. Applying Plasterboard

With the frame in place, it was time to skin the pillar:

1. Measuring and Cutting
   Sheets of 12.5 mm plasterboard were measured against the pillar dimensions, with allowances for the electrical box opening.
2. Fitting Around the Electrical Box
   We marked and cut the opening for the junction box before securing the sheets. This pre‑cut approach saves time and ensures a snug fit.
3. Screwing to the Frame
   Screws were driven into the hardwood studs and blocking, about every 200 mm along edges and 300 mm in the field. Screws were countersunk just below the paper surface without tearing it.

4. Plastering the Surface

To create a seamless, paint‑ready finish, we applied joint compound and tape:

1. Taping Seams and Filling Screws
   Self‑adhesive fiberglass tape was applied over all joints. A first coat of joint compound covered the tape and screw heads, feathering out to blend with the surrounding plasterboard.
2. Second Coat for Smoothness
   After the first coat dried, we sanded lightly and applied a wider second coat, building up the surface until the seams disappeared.
3. Finish Coat for Perfection
   A thin final coat of lightweight finishing compound was applied with a 12‑inch blade. Once dry, a fine‑grit sanding block revealed a flawless surface.

5. Installing the Skirting

To protect the base and complete the look, we added skirting (baseboard) around the bottom of the pillar:

1. Choice of Material
   We used a moisture‑resistant MDF skirting, matching the home’s existing profile.
2. Cutting and Angling
   Mitred corners at 45° joints ensured crisp corners. A coping saw was used where skirting met walls.
3. Fixing in Place
   The skirting was attached with finishing nails into the hardwood bottom plate. Nail holes were filled with wood filler, sanded, and primed.

6. Final Touches and Paint

With the structural and surface work complete, the pillar was ready for paint:

• Priming: A quality primer sealed the joint compound and plasterboard paper.
• Painting: Two coats of eggshell paint provided a durable, easy‑clean finish. We matched the homeowner’s wall color for a cohesive look.

7. The Amazing Result

The finished plasterboard pillar not only provided the needed support for the electrical point but also added a subtle architectural detail to the kitchen. The customer was thrilled:
