Stereotomy: Build a Quarter-Turn Staircase with Winders

5 Days: Monday, March 6th - 10th, 2023, 8AM - 5 PM

Tuition: $950.00

Ages: 16 & Up

Instructor: Patrick Moore

Instructional Delivery Method(s): In person

Prerequisites: None

Program Level: Beginner, Intermediate, Advanced

Program Description:

In this five (5) day week-long workshop, students will build a scaled-down model of a quarter-turn staircase with winders. Students will create a hand-drawn stereotomical drawing to solve for the stair layout. We will use VERY basic calculations.

A quarter-turn staircase is a type of staircase where the direction of flight is changed 90 degrees to connect to different floor levels. It is a type of turning stairs in which the turn is taken either left or right. The change in direction can either be obtained by creating a flat landing or by providing winders. The landing can be provided at various height positions to create a different configuration of the stair layout. These stairs are also called L shaped stairs. L shaped stairs are quite convenient and elegant in appearance. Winder stairs, on the other hand, are a variation of an L shaped stair but instead of a flat landing, they have pie-shaped or triangular steps at the corner transition. The advantages of winder stairs are that they require less space than many other types of stairs and they have more visual interest. Winder stairs seem to create a more seamless transition, visually, as they meander around corners. For this reason, they have gained popularity in modern homes and their compactness has also made them attractive in sustainable home designs. 

Learning Objectives:

  • Learn the basics of stair building codes and minimums

  • How to solve stair layout using stereotomy

  • Create a scaled down model of a quarter turn staircase with winders

  • Learn the basics of stereotomy

  • Use stereotomy to draw a staircase.

  • Extract all critical angles and curves without math or CAD.

  • Build a scale model of the drawing by extracting measurements directly from the 2-dimensional drawing.
