Flight
Definition
A flight is an uninterrupted series of steps or risers that connects two floors, landings, or levels within a building. It serves as a fundamental component of vertical circulation, providing a continuous path and structural stability while accommodating various architectural designs such as straight, curved, or spiral configurations.
Structural & construction notes
Common types of flights include straight, which follow a linear path without turns, and L-shaped or quarter-turn flights that incorporate a 90-degree bend at a landing. Other variations include U-shaped or switchback flights with a 180-degree turn, winder flights that use triangular steps to change direction without a landing, and spiral or helical flights that follow a curved or circular path. More specialized designs include bifurcated or split flights for grand entrances and cantilevered flights that appear to float without visible support. Common materials include wood, metal (steel, aluminum, wrought iron), glass, concrete, and stone. Wood is the most affordable and popular for interiors, typically costing $100 to $250 per step installed. High-durability materials like stone, glass, and metal offer long-term longevity but involve higher initial costs and labor-intensive installation. Synthetic options like composite provide a balance of durability and mid-range costs, especially for exterior use.
