👉TYPES OF STAIR
💫1. A
Dog-Legged Stair consists of two straight flights that run in opposite directions with a landing between them. When viewed from above, it looks like the shape of a dog’s hind leg — hence the name.
⏺It’s one of the most common stair types used in residential and commercial buildings because it efficiently saves space while providing a compact layout.
⏺There’s no open space between the flights, making it ideal for narrow areas or where a neat, enclosed stair design is preferred.
💫2
. Straight Stair⏺A straight stair is the simplest type, consisting of a single, straight flight without any change in direction. It’s easy to design, build, and use, making it common in residential and commercial buildings where space allows.
💫3
. Quarter Turn Stair (L-Shaped Stair)⏺This stair changes direction by 90 degrees, usually at a landing. It’s compact and adds visual appeal, often used where space is limited or for better privacy between floors.
💫4
. Half Turn Stair (U-Shaped Stair)⏺A half-turn stair makes a 180-degree change in direction. It has a landing in the middle and saves space while providing a comfortable transition between floors. It’s common in multi-story buildings.
💫5
. Winder Stair⏺Winder stairs turn corners without a landing, using triangular steps instead. They save more space than L- or U-shaped stairs but require careful design for safety and comfort.
💫6
. Spiral Stair⏺Spiral stairs curve around a central pole or column. They take up very little space and are visually striking, though they are steeper and less comfortable for frequent use.
💫7
. Curved Stair⏺A curved stair has a smooth, continuous bend without a central pole. It’s elegant and often used in luxury homes, hotels, and public buildings for a grand architectural effect.
💫8
. Bifurcated Stair⏺This type starts with a wide flight at the bottom, which splits into two narrower flights that turn in opposite directions. It’s usually seen in grand entrances and public buildings.
💫9
. Circular Stair⏺A circular stair resembles a spiral but has a larger radius, making it easier and safer to walk on. It adds beauty and is often placed in open halls or foyers.
💫10
. Helical Stair⏺A helical stair is similar to a circular one but has no central support. It forms a graceful helix shape and is often a design centerpiece in modern architecture.
