THE FLUSH WALL LOOK
Concealed interior doors.
A cleaner way to design.
We focus on modern frameless doors and frameless interior doors built around concealed door frames and hidden hinges. These concealed interior doors create a flush finish with the surrounding wall, without the traditional visible casing and trim. Our systems feature hardware from Italy and are available for projects across the USA and Canada.
Often described as hidden doors or invisible doors, these systems are designed to make the doorway blend into the architecture. Our invisible door frames are designed to fit standard sizes and wall thicknesses, as well as custom openings up to 82" × 98".

PRECISION HARDWARE
Concealed hinges make the difference.
To achieve a true flush-with-the-wall look, adjustable concealed hinges from CEAM and OTLAV (also known as 3D hinges) are a vital ingredient. Unlike ordinary visible ball-bearing hinges, adjustable hidden hinges allow the door to be fine-tuned and aligned within the opening.

A GUIDE TO THE LOOK
What are frameless, concealed and invisible doors?
Frameless interior doors are designed to sit flush with the finished wall, creating a minimal transition between the door and the surrounding surface. Instead of a conventional raised casing, the system uses a specially designed concealed door frame that is integrated into the wall opening. The result is a crisp architectural detail that works especially well in contemporary homes, offices and other modern interiors.
The terms concealed doors, hidden doors and invisible doors are often used to describe this style. The door itself remains functional and visible when closed, but the frame, hinges and traditional trim are concealed so the door blends more closely with the wall. When finished in the same colour as the wall, a flush door can become a subtle part of the overall interior design.
Concealed interior doors rely on the right combination of frame, hinges, door panel and installation. Adjustable hidden hinges help align the panel, while the concealed frame provides the flush perimeter detail. Depending on the project, customers can choose a complete door set or source the frame and hinge package separately and provide a compatible door panel.
These frameless and hidden door solutions are often selected for bedrooms, closets, offices, hallways, media rooms and other spaces where a clean wall plane is desired. They can also be used to create discreet access to utility or storage areas. Correct opening preparation and coordination with drywall and painting trades are important to achieving the intended seamless appearance.

WHY CHOOSE THIS DESIGN
The benefits of frameless interior doors.
Concealed door systems are designed to make the doorway feel like a natural part of the architecture, rather than a separate feature surrounded by trim.
A clean, minimalist finish
Frameless doors create a smooth transition between the door panel and the wall, helping rooms feel uncluttered and visually calm.
No traditional casing or trim
A concealed frame removes the conventional raised door casing, giving the opening a more integrated, architectural appearance.
Hidden, adjustable hinges
Concealed hinges stay out of view when the door is closed and can be adjusted to help align the panel within the frame.
A door that blends with the wall
When the panel is painted to coordinate with the surrounding wall, an invisible-style door can become a subtle part of the room's design.
ROOMS AND PROJECTS
Where can hidden and concealed interior doors be used?
Frameless interior doors are a versatile option for residential and commercial interiors. Because the frame and hinges are concealed, they can help maintain a consistent wall finish in spaces where traditional door trim would interrupt the design.

- Walk-in closets and storage roomsBlend access doors into a run of cabinetry or a continuous wall surface.

COMMON QUESTIONS
Frameless and concealed door FAQs.
A few helpful answers when comparing hidden doors, invisible doors and flush interior door systems.
What is the difference between a frameless door and a concealed door?
The terms are often used for the same style of interior door system. A frameless door is designed to sit flush with the wall without conventional casing, while a concealed door system uses a frame and hinges designed to be hidden from view when the door is closed.
Are invisible doors actually invisible?
No. The door panel is still present and can be seen when you look closely. “Invisible door” describes the visual effect created when the frame, hinges and trim are concealed and the door finish blends with the surrounding wall.
Can concealed doors be painted to match the wall?
Primed flush door panels can be painted as part of the finishing process. Matching the wall colour can help the door blend into the room, subject to the selected panel and finishing specifications.
Can I purchase only the concealed frame and hinges?
Yes. Depending on the project, you can choose a complete door set or a frame-and-hinge package and provide a compatible door panel. Review the door system details to confirm the appropriate configuration.
Are frameless interior doors available in custom sizes?
Custom openings may be possible, depending on the selected system and project requirements. Share your opening dimensions and wall details with us so we can help identify a suitable option.
Can concealed interior doors be installed in an existing home?
They may be suitable for renovation projects, but the wall construction, opening dimensions and stage of construction all matter. The installation may require coordination with drywall and painting trades. Review the technical information before planning the work.
