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.

Questions about Under-Stair Shelving

What are the essential tools I need for accurate measurements in an angled under-stair space?

Beyond a standard measuring tape and pencil, an angle finder or a protractor is crucial for accurately capturing the slope of the stairs. Also, a long straight edge or level will help you mark level lines and check for plumb, ensuring your shelves are straight and true despite the angled surroundings.

Beyond basic hand tools, what power tools would make this under-stair shelving project easier for a beginner?

A miter saw or circular saw with a guide will significantly improve the accuracy and speed of cutting your lumber, especially for repetitive cuts and angles. An electric orbital sander is also highly recommended to efficiently prepare all pieces for finishing, saving you hours compared to hand sanding.

What are the most important safety precautions I should take when cutting and assembling lumber for this project?

Always wear safety glasses to protect your eyes from sawdust and flying debris. Use hearing protection when operating power tools and ensure your work area is clean and well-lit to prevent accidents. Make sure all lumber is securely clamped or supported before cutting to avoid kickback.

The project is listed as 'beginner' and '3 days'. Is this estimated time realistic for someone completely new to woodworking?

While classified as beginner, the 3-day estimate often assumes some prior familiarity with tools and a focused work schedule. If you're completely new, allow for extra time, especially for careful measuring, precise cutting, and thorough finishing, as these steps are critical for a professional-looking result. Don't rush the process.

What's a common mistake beginners make when measuring for under-stair shelving, and how can I avoid it?

A frequent mistake is not fully accounting for irregularities in the wall or floor, or failing to precisely capture the stair's varying angles, leading to shelves that don't fit snugly. To avoid this, create a detailed template using cardboard or scrap material for complex angles, and always 'measure twice, cut once' to confirm dimensions.

Are there alternative materials to dimensional lumber that might be easier for a beginner or offer a different look for under-stair shelving?

Plywood or MDF (medium-density fiberboard) can be good alternatives, often providing flatter surfaces and being easier to cut into large panels for shelves and backs. These materials typically require edge banding or painting for a finished appearance, which might add a different aesthetic and complexity to the finishing steps. Consider pre-made shelving kits for the simplest approach, though customization will be limited.
