Modern architecture is increasingly breaking away from the “box.” From residential villas with sweeping organic corridors to hospitality projects with fluid partitions, curved walls are being used to create a sense of movement and “liquid space.”

However, the biggest obstacle in a curved wall is the door. A standard flat door creates a visual “break” that ruins the continuity of the curve. At Linvisibile, we’ve mastered the art of the Alba Curved Hinged doors, ensuring that the door is not a disruption, but a seamless continuation of the wall’s radius.

The strategic approach to curved walls

The Concave and Convex Challenge

A door in a curved wall must account for two different realities: the concave side (inner curve) and the convex side (outer curve).

• The Solution: The Alba Curved Hinged door is engineered to follow the specific radius of the wall perfectly. The leaf is manufactured with a precise curvature that matches the wall’s footprint, ensuring it remains perfectly flush on the curved side when closed.

Managing Non-Orthogonal Geometry

In many contemporary projects, walls meet at sharp, non-90-degree angles to maximize views or light. In these “non-orthogonal” layouts, traditional door frames are impossible to align without creating awkward visual gaps.

• The Solution: Our flush-to-wall technology eliminates the need for corners and moldings. The Alba Curved door becomes a clean, sculptural cut within the wall, maintaining the geometric integrity of the architect’s plan regardless of the angle.

Technical Mastery: The Alba Curved Hinged Door

Designing a hinged door for a curved wall requires millimetric accuracy in both the frame and the door leaf to ensure the swing remains smooth and the gaps remain consistent.

The Linvisibile Alba Curved system is designed to:

• Custom Radius Engineering: We don’t provide “standard” curves. Every frame and leaf is manufactured to the specific radius of your project, ensuring a perfect fit regardless of how tight or wide the curve is, from 700 mm up to 2600 mm radius.
• Total Integration: The door can be finished in various material—lacquer, wood, or textured clay—to match the surrounding wall. This turns the door into a hidden passage that respects the organic flow of the space.

Designing with curves: Pro-Tips

• Radius Precision: Always specify the finished wall radius (including plasterboard or render) to ensure the door sits perfectly flush.
• Swing Logic: For curved hinged doors, opening toward the convex side (the outside of the curve) is generally more space-efficient and maintains the visual “sweep” of the wall.
• Material Warning: Heavily grained woods or patterned stones can be challenging on tight curves. Opt for vertical grains or monochromatic finishes for a smoother visual transition.

Embrace the Curve. Don’t let your layout be limited by 90-degree angles. Discover how the Alba Curved Hinged door brings fluidity and precision to the most complex architectural designs.
