Planum 0010 Solid Black with Black Hidden Frame 18" x 80" Right-hand Inswing Black Frame Description

SET INCLUDES:
One door slab with Black aluminum edge profiles
Black aluminum concealed frame with integrated sealant
Black door handle
Magnetic locking mechanism
Black concealed hinges with 3D adjustment

A QUIET KIND OF LUXURY

There is a certain beauty in interiors that feel effortless. Where light moves freely, lines remain uninterrupted, and every element belongs so naturally that nothing seems out of place.

The PLANUM 0010 Hidden Door was conceived with this philosophy in mind. Its clean geometry and understated presence allow it to become part of the architecture itself. Designed to blend seamlessly into the surrounding wall, it creates a sense of continuity and quiet sophistication, allowing the space to unfold without unnecessary visual interruption.

Finished in Solid Black, the door brings depth, drama, and a distinctly architectural character to the interior. Its rich, dark surface creates a bold yet restrained visual presence, while matching Black aluminum edge profiles extend the monochromatic aesthetic through every detail. The result is a composition defined by clean geometry, visual continuity, and the quiet confidence of simplicity.

DESIGNED TO BECOME PART OF THE WALL

The concealed aluminum frame allows the door to align flush with the wall on one side, creating a clean, uninterrupted surface. Without traditional casing to interrupt the surrounding architecture, the doorway feels integrated rather than added — a considered detail that enhances the harmony of the interior.

PRECISION IN EVERY DETAIL

3D-Adjustable Concealed Hinges
The concealed hinges allow precise three-dimensional adjustment, helping achieve proper door alignment and consistent gaps during installation.

Smooth Magnetic Closing
The magnetic locking mechanism provides a quieter, smoother, and more pleasant closing experience, complementing the understated character of the design.

Coordinated Black Hardware
Black aluminum edge profiles and matching hardware create a unified, monochromatic expression. With no contrasting metallic accents, the design remains pure and uninterrupted, allowing its geometry and proportions to take center stage.

Note: Alternative hardware styles and colors are available upon request.

A BALANCE OF DESIGN AND FUNCTION

Designed to complement a wide range of interior styles, the PLANUM 0010 combines architectural simplicity with thoughtful everyday functionality. Its restrained aesthetic allows surrounding materials, textures, and furnishings to take center stage while maintaining a distinctive sense of refinement.

Because luxury does not always announce itself. Sometimes, it is found in the depth of a dark surface, the continuity of a monochromatic design, and the quiet confidence of details that work together as one.

IMPORTANT INSTALLATION NOTE
The concealed frame must be installed during the renovation process, before the final wall finishing is applied. Proper planning and coordination with the installation team are essential to achieve the intended seamless appearance.

Please note: The door slab aligns flush with the wall on one side only.
