What Are Transoms and Sidelights?
When creating a grand entryway, every detail matters. From the craftsmanship of your front door to the glass elements surrounding it, these design choices shape the first impression of your home. Two features that often elevate a luxury entrance are transoms and sidelights—architectural elements that combine form and function to transform a simple doorway into an inviting focal point.
If you’ve ever admired a front door framed with beautiful glass above or beside it, you’ve likely encountered these details. But what exactly are transoms and sidelights, and why are they so beloved in high-end home design? Let’s explore.
Understanding Transoms
A transom refers to the horizontal architectural element that sits above a door or window, typically separating it from a smaller window above. The glass portion above this beam is often called a transom window or transom light.
Historically, transom windows were operable, designed to let in fresh air while the door below remained closed—a feature that was especially useful before the era of air conditioning. Today, most transoms are fixed, chosen for their aesthetic appeal and the soft, natural light they invite into the home.
Why Designers Love Transoms
- Adds Height and Grandeur – A transom visually elongates your entryway, making ceilings feel taller and spaces more open.
- Invites Natural Light – Positioned above eye level, a transom window brightens interiors without sacrificing privacy.
- Versatile Design Options – From classic rectangular panes to elegant arches and custom curved shapes, transoms can be tailored to suit any architectural style.
Understanding Sidelights
Sidelights are the vertical, narrow windows installed on one or both sides of a door. They are fixed in place and typically serve the dual purpose of increasing natural light and enhancing the door’s visual presence.
Imagine stepping into a home where the entryway glows with sunlight streaming in from tall glass panels beside the door—that’s the effect of sidelights. They extend the door’s proportions, frame it beautifully, and create a more spacious, bright environment for guests the moment they enter.
Benefits of Sidelights
- Enhances Natural Light – Perfect for brightening foyers or hallways that might otherwise rely solely on artificial lighting.
- Creates a Welcoming Feel – Sidelights visually expand the doorway and give it a stately presence.
- Offers Design Flexibility – From clear to frosted, textured, or decorative glass, sidelights can be customized for privacy and style.
The Perfect Pairing: Transoms and Sidelights Together
Individually, transoms and sidelights are beautiful. Together, they create a truly show-stopping entrance. When a door is flanked by vertical sidelights and crowned with a transom, the result is a cohesive, architectural statement that feels both elegant and intentional.
- Sidelights emphasize vertical lines and symmetry.
- The transom caps the design, adding horizontal balance and extra light.
- Coordinated glass patterns—such as matching mullions or decorative grids—unite the entire ensemble into a single work of art.
In luxury steel door systems, these elements are often fabricated as one integrated unit, ensuring precision in installation, weather sealing, and energy performance. This level of craftsmanship transforms an ordinary doorway into a sophisticated entry feature.
Design Considerations for Luxury Homes
When incorporating transoms and sidelights, proportions and details are key. Here are a few considerations for creating a truly elevated design:
- Door and Ceiling Height – Transoms require vertical space above the door. High ceilings allow for taller glass panels and a more dramatic impact.
- Symmetry and Proportion – Paired sidelights frame the door beautifully, while a single sidelight can be a sleek option for contemporary designs.
- Glass Choices – Consider frosted or textured glass for privacy, or clear glass to maximize light and views. Decorative glass can introduce a custom, artisanal touch. View our different glass options here.
- Security and Efficiency – Opt for tempered or laminated glass for security, and insulated glass for energy efficiency—especially in larger, light-filled openings.
Why High-End Homeowners Choose Transoms and Sidelights
Luxury homes often feature these architectural elements because they deliver both visual drama and practical benefits:
- Enhanced Curb Appeal – A door framed with glass immediately signals refinement and attention to detail. Not only does it catch the eyes of neighbors, but also increases your home’s value.
- Light-Filled Interiors – Natural daylight creates warmth, making spaces feel more welcoming and expansive.
- Timeless Style – Whether your home leans classic or modern, transoms and sidelights offer a versatile design language that never goes out of style. Discover your different style options we offer.
- Bespoke Craftsmanship – Custom steel frames, intricate muntins, and tailored glass options allow each entryway to be as unique as the home itself.
