Custom French Doors with Sidelights: Transform Any Opening Into a Home Office,Bedroom,or dining room
Custom French Doors with Sidelights: The Best Way to Close In Any Opening — And Make It Beautiful
You have a wide opening in your home — maybe an arched doorway left over from a renovation, an open pass-through between rooms, or a large rectangular gap that was never properly finished. You want to close it in. You want a home office with real walls and a real door. You want a bedroom that feels private. You want a space that feels designed — not just functional.
The problem? Standard doors from a hardware store won't fill a wide or arched opening. They come in fixed sizes, hollow cores, and finishes that look exactly like every other door in every other house on the block. They weren't built for your opening. They weren't built for you.
A custom French door set with sidelights is the solution — and it's one of the most dramatic, high-impact upgrades you can make to any home. This guide covers everything: what a sidelight is, how to measure your opening, which style is right for your room, and why handcrafted solid wood makes all the difference.
What Are Sidelights — And Why Do You Need Them?
Sidelights are fixed glass panels installed on one or both sides of a door. They don't open — they're permanently set into the frame — but they let light pass through, create visual continuity between spaces, and fill wider openings that a single or double door can't cover on its own.
Think of them this way: a standard double French door covers roughly 48 to 60 inches of opening. But what if your opening is 84, 96, or even 120 inches wide? That's where sidelights come in. Custom sidelights fill the remaining space on either side of the doors, matching the exact glass style and wood finish of the doors themselves. The result is a seamless, intentional-looking installation that looks like it was always meant to be there.
Beyond filling wide openings, sidelights serve three important design functions:
- They bring light into rooms that need it. A home office tucked into a corner of your house loses its cave-like feel the moment natural light starts pouring through glass panels. Sidelights allow you to see into or out of a closed room without opening the door.
- They maintain visual connection between spaces. In open-concept homes, sidelights let you divide a space without making it feel chopped up or disconnected. You gain privacy without losing the sense of flow.
- They make the door set feel architectural — not just functional. A set of French doors flanked by matching sidelights looks like a design feature, not an afterthought. It elevates the entire room.
The Perfect Application: Closing In an Arched or Wide Opening
One of the most common reasons homeowners come to us is because they have an opening that doesn't work with standard doors. This is especially common in:
Open-Concept Homes
If your living room, dining room, and kitchen are all connected without walls, you may find yourself wanting more separation — especially for noise control, privacy during work calls, or simply to make each space feel more defined. A custom French door set with sidelights lets you close off a section of the open floor plan without committing to permanent drywall construction. You get the separation you want with the ability to open everything back up whenever you choose.
Arched Openings
Arched doorways are one of the most architecturally beautiful features in a home — and one of the hardest to fill with a standard door. Our custom arched door sets are built to follow the exact curve of your opening. The arched transom above the doors fills the rounded top portion, while the French doors and sidelights below handle the rectangular section. The result is a set that fits the opening like it was made for it — because it was.
Our current arched opening set is built to 96 inches wide x 96 inches tall to center of arch, with two 18-inch sidelites and two 24-inch French doors. Jamb and casing are included. If your opening is a different size, contact us — we build to custom specifications.
Converting a Room Into a Home Office
The home office boom changed how people think about their space. A dedicated office — one with a real door you can close, soundproofing from the rest of the house, and a visual separation from the living areas — has become one of the most requested home upgrades of the last five years. A custom French door set with sidelights gives you exactly that, while keeping the space feeling bright and connected rather than closed off and dark.
The glass panels in the doors and sidelights are the key. You're not sealing the room into darkness. You're framing it. Light still flows. The connection to the rest of the home is preserved. But when the doors are closed, the acoustic separation — especially with solid pine construction — is dramatically better than an open doorway or a hollow-core door.
Creating a Bedroom From a Previously Open Space
Bonus rooms, loft spaces, and oversized dens are prime candidates for bedroom conversions. A custom door set with sidelights gives the new bedroom a proper entrance that feels intentional and finished — not like a renovation project that was never quite completed. Choose frosted or privacy glass for the sidelights and lower door panes if privacy is the priority. Choose clear glass if you want to maximize light and maintain visual connection to the rest of the home.
What's Included in a Custom Door Set with Sidelights
When you order a custom French door and sidelight set from Tumbleweed Home Furnishings, here is exactly what you receive:
- Two custom French doors — solid pine construction, glass panel upper section with raised panel bottom, built to your exact width and height specification
- Two matching sidelites — fixed glass panels in the same style and finish as the doors, built to fill your specific opening width
- Full jamb and casing set — the door frame (jamb) and decorative trim (casing) are included so the installation looks finished from day one
- Matte black hinge hardware — pre-mounted on the jamb for proper alignment
- Complete assembly instructions — the set ships disassembled for safer transport and reassembles on-site. If you need the full set delivered intact, contact us for a custom shipping quote.
Every piece of wood in the set is solid pine — no hollow core, no foam, no MDF shortcuts. Every joint is built using traditional mortise and tenon joinery. This is not a kit you assemble with cam locks and dowels. It is a real wood door set, handcrafted to last a lifetime.
Understanding Your Opening: How to Measure Correctly
Measuring for a door and sidelight set is more involved than measuring for a single barn door, but it's not complicated if you follow these steps carefully.
Step 1 — Measure the Rough Opening Width
Measure the total width of the opening from stud to stud (inside the framing, not including any existing casing or trim). Write this number down in inches.
Step 2 — Measure the Rough Opening Height
For a standard rectangular opening, measure from the floor to the underside of the header. For an arched opening, measure from the floor to the highest point of the arch at the center.
Step 3 — Decide on Your Door Width vs. Sidelight Width
For most openings, the doors should make up roughly half the total width and the sidelights should fill the remaining space. For example, in a 96-inch opening: two 24-inch doors (48 inches total) plus two 18-inch sidelights (36 inches total) plus frame and casing equals approximately 96 inches. This is our standard configuration — contact us with your exact measurements and we'll design the split for you.
Step 4 — Note Your Ceiling and Wall Conditions
For arched openings, take a photo and note the exact dimensions of the arch. The radius and starting height of the curve determine how the arched transom is built. For standard rectangular openings, simply note whether the header above the opening is exposed or finished.
Step 5 — Contact Us Before Ordering
Custom door sets with sidelights are more complex than a single door order. We strongly recommend reaching out via email or chat before placing your order so we can confirm your measurements, discuss your finish options, and make sure you're ordering exactly the right configuration for your opening.
Glass Options: Clear, Textured, or Privacy?
The glass in your French doors and sidelights is one of the most important decisions you'll make — and it depends entirely on how you want to use the space.
Clear Glass
The classic choice for French doors. Clear glass maximizes light transmission, maintains visual connection between spaces, and shows off the interior of the room beyond. Best for: home offices where you want a bright, open feel; living-to-dining transitions; rooms where the view through the doors is attractive.
Textured / Hammered Glass
Textured glass — like the hammered or patterned glass shown in our arched door set — blurs the view through the panels while still allowing generous light transmission. You can see light and movement through the door, but not specific details. Best for: home offices where you want privacy without darkness; bedrooms where you want light but not full visibility; any application where you want the visual effect of glass without complete transparency.
Frosted Glass
Frosted glass provides the highest level of privacy while still letting light through. The view through the panels is completely obscured. Best for: bedrooms that open to high-traffic areas; home offices used for video calls or sensitive work; bathrooms and dressing rooms.
Finish Options: How to Tie Your Door Set Into Your Home
Every Tumbleweed door set is available in the following finish options:
Unfinished Pine — Natural pine, ready for you to stain, paint, whitewash, or seal exactly as you choose. Best option if you need to match an existing specific color, stain, or wood tone in your home.
Custom Painted — Choose any color from our paint chart and we'll apply it before shipping. Antique White, Classic White, Black, Gray, Sage Green, and hundreds of other options. Painted finishes are the most popular choice for home offices and bedrooms where you want the doors to feel integrated into the room rather than standing out as a feature.
Stained — A stained finish celebrates the natural grain of the pine. From light honey tones to rich dark walnut, a stained finish gives the door set warmth and character that painted doors can't replicate. Works especially well in rooms with other natural wood elements — hardwood floors, wood-beam ceilings, walnut furniture.
Why Solid Pine and Mortise and Tenon Joinery Matter More Than You Think
Walk into any big-box home improvement store and you'll find interior French doors. They'll be hollow-core, finished with a thin wood veneer, and built with the same staple-and-glue construction used in mass production. They look fine. Until you install them.
A hollow-core French door in a wide opening with sidelights has a fundamental problem: the door panels are too light. They don't hang straight under their own weight. They flex when you grab the handle. The hinges loosen over time because there's no solid wood for the screws to bite into. And the thin veneer surface chips and peels within a few years of regular use.
Solid pine is different. A solid pine French door has real mass — it hangs straight, stays straight, and operates with the kind of smooth, substantial feel that tells you immediately it's real. The mortise and tenon joinery — where the horizontal rails and vertical stiles of the door are connected by interlocking wooden joints, not metal fasteners — creates a connection that gets stronger over time, not weaker. It's the same construction method that has been used by furniture makers and door builders for centuries. It works.
When you invest in a custom door set for a home office conversion or bedroom creation, you're not just buying a door. You're finishing a room. You're defining a space. The quality of the door will be felt and noticed every single day — every time someone opens it, closes it, or simply walks past it. Solid pine with traditional joinery is the right material for that kind of permanent, daily-use installation.
Real Applications: What Our Customers Build
The Home Office That Needed a Real Door
A customer had a wide arched opening between their living room and what was originally intended to be a formal sitting room. The room sat unused because it had no door — just an open arch. We built them a custom arched French door set with two 24-inch doors, two 18-inch sidelights, and an arched transom following the curve of the opening. The result: a fully functional home office that closes off completely for calls and deep work, opens up for natural light and connection to the rest of the house, and looks like a design feature that was always planned.
The Bonus Room Bedroom
A customer had an oversized bonus room with a wide rectangular opening at the top of their stairs. They wanted to convert half of it into a bedroom for their college-age child who moved home. We built a custom door set to fill the full width of the opening, with frosted glass sidelights on both sides for privacy. The new "bedroom" feels intentional, finished, and completely separate from the remaining bonus room area.
The Open-Plan Privacy Problem
A couple working from home needed to separate their open-plan living and dining area so one person could take calls without interrupting the other. A custom French door set with clear glass sidelights now divides the two spaces cleanly. When both doors are open and folded back against the wall, the room feels completely open. When closed, each person has their own acoustic space. The glass keeps the natural light flowing through both rooms.
Frequently Asked Questions
Can you build a door set for any size opening?
Yes. Every Tumbleweed door set is custom built to order. Our standard arched configuration is 96 inches wide x 96 inches tall to center of arch with two 18-inch sidelights and two 24-inch French doors — but we can build to virtually any dimension. Contact us with your exact opening measurements before ordering and we'll design the right configuration for your space.
Is the jamb and casing included?
Yes. All of our custom door and sidelight sets include the full jamb (door frame) and casing (decorative trim). Everything you need to complete the installation is included. The set ships disassembled with assembly instructions. If you need the complete set delivered fully assembled, contact us for a custom shipping quote.
How do I handle the arched portion of my opening?
Send us a photo of your arched opening along with its measurements — total width, total height to the center of the arch, and the height at the sides where the arch begins. We'll build a matching arched transom that fills the rounded upper section while the French doors and sidelights handle the rectangular portion below. The entire set is designed as one cohesive unit.
What glass option is best for a home office?
It depends on your privacy needs. If you just want light and an open feel, clear glass is the classic choice. If you need visual privacy for calls and sensitive work but don't want to seal out light, textured or hammered glass is the best option. If you want full privacy and maximum sound separation, frosted glass with a solid lower panel is the right call.
How long does production take?
Custom door sets with sidelights are more involved than single doors and typically require 14–18 weeks from your order date, depending on complexity and current production schedule. Contact us to confirm current lead time before ordering. Plan ahead — order before your renovation begins, not after.
Do you need a contractor to install this?
Installation difficulty depends on your opening conditions. For a clean, pre-framed rectangular opening, an experienced DIYer can handle it with the right tools. For arched openings or any opening that requires new framing, we recommend working with a skilled carpenter or contractor. The jamb and casing are included, but framing any new rough opening is a separate scope of work that requires construction experience.
How is this different from what I'd find at Home Depot or Lowe's?
Mass-market interior French doors are hollow-core, built in fixed standard sizes, and finished with thin wood veneer over a cardboard honeycomb interior. Our doors are solid pine throughout — no hollow core, no foam, no veneer shortcuts — built with mortise and tenon joinery and sized exactly for your opening. There is no comparison in weight, feel, durability, or longevity. Our doors are heirloom pieces. Theirs are commodity products.
