6. Bifurcated stairs

1: Straight Stairs

straight stair is no change in direction on any flight between two successive floors Straight stairs are generally use for the small house and type of stairs are used in that condition when the stair there is not any place in the house and stairs runs are straight between tow floors. and this types of staircase is also used for the single flight or double. with landing.

2:Half  turn stair

Half turn stairs can change their direction on 180 degree. and these kind of stair his more 3 types.

 

1: Dog legged Stair

2: open newel Half turn stair

3: Geometrical half turn stairs



Dog Legged stairs:

Dog legged stairs comes under the category of newel stairs in which newel posts are provided at the beginning and end of each flight. and this types of design is mostly constructed for educational building.

open newel Half turn stair

this types of stairs his open newel half turn stairs. and this stair has a well between the outer strings.
