Initial Measurements and Platform Design

What happens in this clip

Begin by accurately measuring the total rise (vertical height) and run (horizontal depth) for the entire staircase. Design an initial landing platform strategically to prevent the stairs from encroaching into adjacent spaces, such as a hallway. It is crucial to ensure adequate head space above this landing. If the initial platform height results in insufficient head clearance, adjust its level accordingly. Additionally, consider designing the landing platform to be about 12 inches longer than strictly necessary for a 3-foot wide stair tread, as this extra length can simplify turns and reduce the need for complex custom cuts later.

Goal: Determine overall stair dimensions and initial platform placement for optimal space and head clearance.

About the full video

This project provides a detailed guide on the critical considerations for designing and building stair stringers, especially in constrained areas. It covers essential measurements like rise and run, strategies for platform placement to optimize space and headroom, adapting to different finished floor heights, and correcting common calculation errors. The video emphasizes thoughtful planning to ensure both functionality and safety in custom stair construction.

Step 1 of 10: Measure the Under-Stair Space

Using a tape measure, record the exact dimensions of the under-stair area. Measure at the front, back, and at various points in between to account for any sloping or irregularities in the wall or floor. Note any obstructions like electrical outlets or HVAC vents.
