Custom Cornices Fabricated in Boca Raton, FL
Cornices add structure, detail, and a finished architectural look to custom window treatments. Installed above drapery, shades, or other window coverings, a cornice can conceal hardware, frame the window, and create a more polished design.
What Are Cornices?
Cornices are structured top treatments installed above a window. Unlike softer fabric valances, cornices are built on a firm frame, giving them a more architectural appearance.
They can help add height, balance, and visual weight to the window, especially when paired with custom drapery, Roman shades, roller shades, or other window treatments.
Benefits of Custom Cornices
Conceal Window Treatment Hardware
Cornices are a clean way to hide rods, tracks, brackets, and shade hardware, keeping the focus on the design of the window treatment.
Add Structure and Proportion
Built on a frame, cornices add strong lines and architectural shape that can make a window feel taller, wider, or more balanced.
Coordinate With the Room Design
Covered in fabric, finished with welt, or detailed with trim, cornices can coordinate with drapery, bedding, pillows, and upholstery.
Types of Cornices
At Nez Designs, custom cornices are made to fit the window, the treatment underneath, and the overall style of the room. Whether the design is simple and tailored or more decorative and detailed, each cornice is built around the scale, fabric, shape, and finishing details of the project.

Fabric-Covered Wood Cornices
Fabric-covered wood cornices are built from a structured frame and then covered with the selected fabric. This creates a tailored look that can coordinate with the rest of the room.
This option works well when the goal is a clean, upholstered appearance that still has the strength and shape of a structured cornice.
Welt Cornices
Welt cornices include fabric piping along the edges of the cornice. The welt detail helps define the shape and gives the finished piece a more refined, tailored appearance.
Welt can be subtle and tone-on-tone or more decorative depending on the fabric and design direction.


Trim Cornices
Trim cornices use decorative edging or applied detail to create a more finished appearance. Trim can help emphasize the shape of the cornice and add another layer of texture, contrast, or architectural interest.
This option is often used when the room calls for more detail than a plain fabric-covered cornice.
Shaped Cornices
Shaped cornices, also called contoured cornices, are designed with a custom profile instead of a straight lower edge. Common shapes may include arches, scallops, curves, or other custom outlines.
A shaped cornice can help soften the window, echo architectural details, or create a more decorative focal point.

Custom Cornice Details
Unlike a softer fabric valance, a cornice is built on a firm frame for clean lines and a more architectural finish; for softer styles, see our custom top treatments. A custom cornice can be designed around the window size, room style, and fabric selection. Details may include:
- Fabric selection
- Cornice height and projection
- Straight or shaped lower edge
- Welt, trim, or decorative detailing
- Coordination with drapery, Roman shades, or roller shades
- Lining and finishing details
- Scale and proportion based on the window and room
