Nedfällning

Nedfällning is a Swedish term that describes the act or result of sinking, lowering, or recessing a component into another structure so that its outer surface sits flush with the surrounding surface. The concept is used across several fields, most prominently in carpentry, design, and architecture.

In carpentry and furniture making, nedfällning refers to inset or flush-fitting arrangements where a panel, door, or hardware sits recessed within a frame rather than projecting. Common applications include nedfällning av luckor and panels, achieved by milling grooves, rebates, or mortises to create a cavity into which the part is lowered or folded. Some assemblies use hinges or drop‑down mechanisms to allow movement while maintaining a flat surface when closed.

In architecture and building, nedfällning can describe insets for elements such as floor panels, electrical outlets, or lighting fixtures installed at or below surface level to avoid protrusions and improve aesthetics or accessibility. It can also denote decorative or functional inlays where materials are recessed into a plane.

Methods and considerations vary: rebates, grooves, mortises, and hidden hardware are commonly used, with emphasis on achieving precise alignment and proper tolerances to keep surfaces flush. Advantages include a cleaner appearance, reduced snag hazards, and increased edge protection; drawbacks can include more complex fabrication, higher costs, and maintenance requirements to preserve alignment over time.
