A compact yet tall LEGO® arch brick in pink, this 1 x 3 x 3 element (Part 13965) introduces smooth curved openings while maintaining strong vertical structure. The proportions make it especially useful where additional height is needed without increasing footprint, allowing for more defined architectural spacing.

Shape and Structural Design

The extended height of this arch creates a pronounced curve that frames openings cleanly, making it suitable for doorways, elevated window sections, and layered wall designs. Its geometry supports stable stacking above and around the arch, helping maintain consistent alignment in structured builds.

Architectural Use Cases

• Doorway frames: Adds height and curvature to entrances without widening the structure
• Window detailing: Creates arched window tops within modular buildings
• Bridge supports: Works as a compact support element with visual depth
• Layered walls: Breaks up flat surfaces with curved architectural variation
