On first glance, this staircase reads as restrained. White oak treads rise with natural warmth, metal balusters hold their disciplined rhythm, and the painted black railing traces a clean, straight path upward. Then you notice the elliptical stringer wrap, and the whole composition shifts. Unlike a circular curve drawn with a compass, an ellipse requires mathematical calculation and a craftsman who knows how to make that complexity disappear. Here, it does exactly that. Natural light finishes the story. Moving through the space across the day, it deepens the oak grain, catches the metal, and lets the black railing guide the eye along the handrail's elliptical path from start to finish. Restraint brought the design this far. One well-executed curve made it memorable. 1976-2026 © Century Stair Company

This particular interior door model is based on the ideas discussed below and will be a welcome addition to your decor in any configuration. The concept of infinity goes back to ancient Greece, with Zeno of Elea (the celebrated author of the paradoxical riddles which people have been debating for thousands of years now) being first to theorize about it mathematically. Physicists and mathematicians have been infatuated with it ever since. Artists, from old masters to modern impressionists, are intimately familiar with the concept: knowing how to build perspective is one of the plein air painter’s basic skills. Vanishing points, corresponding to mathematical points of infinity located at an infinite distance from the observer, are the crux of any landscape composition. This multi-panel interior door model was inspired by the idea that space, distances, and forms can be realistically represented through elegance. Think of it as an interior door that makes the room on which it opens seems more spacious than it might actually be in reality.

Designed by Tim Higbee of Closet Works Making our upper cabinets on the mud room wall directly abut and attach to the existing kitchen cabinets while adding a similar crown was a challenge. That required mathematics and exact dimensions of the depths of both cabinetry, the height both of the existing crown moldings and their reveals, and how the two would interact.
