Building a set of stairs is an essential construction project that can seem daunting to DIYers. With the right planning and preparation, constructing stairs is an achievable weekend project for intermediate to advanced DIYers. In this comprehensive guide, we will walk you through the entire process of building stairs, from laying out the design and calculating dimensions to installing railings and finishing touches. Follow along each step and you’ll have attractive, functional, and safe stairs to access your multi-level home.

Choose a Stair Type

The first step in any stair building project is deciding what style of stairs you want to construct. There are several considerations when selecting stairs:

Straight or Curved

Straight stairs have treads that run in a straight line from top to bottom. They take up less space but can feel steep. Curved stairs have treads radiating in an arc, making the climb easier by hugging the curve. Curved stairs take up more space.

Open or Closed

Open stairs have open risers allowing you to see between steps. This gives a lighter look but is harder to climb. Closed stairs have a backing on each step for support and safety.

Number of Steps

More steps mean a longer staircase that is easier to climb. However, space is often a limiting factor.

Once you’ve weighed these options, choose a stair design that fits your space and needs. The most popular choices are straight stairs with closed risers.

Calculate Stair Dimensions

Critical calculations are required to ensure your stairs are the right size and height. If your measurements are off, the finished stairs will be unsafe and out of code. Follow these steps to calculate dimensions:

Determine Total Rise and Run

The total rise is the height you need to reach, from the bottom floor to the top. Measure directly from floor to floor.

The total run is the horizontal distance needed to cover the rise. Generally, allow 12” of run for every 6-7” of rise. For example, a rise of 96″ would need a run of about 144″ (12 times 12”).

Find Number of Steps Needed

Divide the total rise by the ideal rise of each step to get the number of steps. For residential stairs, optimal step rise is between 6” to 7.75”. Using the example above, 96” rise divided by 7” ideal rise equals 13 steps.

Calculate Step Dimensions

Take the total run distance and divide by the number of steps to find the tread depth of each step.

For the example:
144” total run divided by 13 steps = 11” tread depth

The ideal tread depth is between 10”-14”. Adjust as needed.

Many building codes require a minimum 3” overhang for the lowest and highest steps. Account for this in your planning.

Choose Materials

Sturdy and attractive materials will give you stairs that last. Some popular options include:

Wood: Oak, pine, maple all make strong and stunning stairs. Sealing the wood is essential.
Concrete: For contemporary or industrial design. Forms are built and concrete is poured into place.
Metal: Wrought iron, steel, and aluminum can be used for support and railings.ensure they are properly supported.
Tile: Use on concrete stairs or as a covering for wood treads. Excellent durability.

Combining materials, like concrete stairs with wood railings, can create designer looks. Use quality, weather-resistant materials for safety and longevity.

Construct the Stair Box

The stair box (also called the rough frame) provides the core structure to support the steps. Build this solidly from:

Stringers: These sloped beams (usually 2×12 lumber) hold up the steps. Calculate the exact slope needed using rise and run.
Header: Supports the front ends of steps. Made of 2×12 lumber.
Skirts: Vertical boards along the sides that close off stairs. Often 1×6 or 1×8 boards.

Construct the framework using a high-quality wood. Check each angle carefully as work progresses. Consult local building codes for specifics on designing load-bearing staircases. Use tightly driven nails, screws, and glue for maximum strength.

Install the Treads and Risers

With the stair box complete, cut the treads and risers to size. Recommendations:

Treads: Use 2×12 lumber for maximum support. Other durable materials like oak work too.
Risers: Cut 1×6 or 1×8 boards to fit snugly from tread to tread. Close off riser backs.
Landing Boards: Top and bottom platforms. Use 3/4″ plywood.

Carefully measure and cut each piece. Treads can overhang the skirt boards by 1-3 inches on each side. Drill pilot holes and use exterior wood screws to fasten everything securely.

Build Support Railings

Railings are vital safety components. Follow code specs for railing height and spindling space. Use heavy-duty wood like oak for posts. Iron balusters and metal braces add strength.

Basic railing construction:

Set vertical 4×4 posts into the stairs framework.
Attach horizontal rails between the posts. Used 2×4 lumber.
Fill in balusters spaced 3-4 inches apart for safety.
Add decorative newel posts on ends for aesthetics.

Use bolts and brackets to reinforce joints. Make sure railings are firmly anchored and won’t budge or sway. Add returns and wall rails for full protection.

Finish and Seal the Wood

Unfinished wood will quickly show wear and rot. Protect stairs with:

Weather resistant sealant: Use marine varnish or water-sealant made for exterior wood.
Paint/stain: For color, use outdoor grade paint or penetrating stains.
Water repellant: Apply water repellant to fortify against moisture damage.

Apply finishes carefully, following manufacturer directions. Maintain the finish regularly to keep wood stairs looking their best.

Safety Tips for Stair Building

Adhere to all local building codes and standards.
Only cut stringers/framing lumber along the ends to retain strength.
Use sturdy brackets/adhesives for solid connections.
Ensure staircases are fully stable and level before use.
Test railings vigorously by shaking before trusting them.
Add lighting on and around stairs to improve safety and visibility.
Use textured surfaces or tread covers to reduce slips.
Child and elderly proof by installing stair gates when needed.

Following careful construction methods and safety practices will keep your new stairs sturdy for decades of regular use.

Common Questions about Stair Building

Building stairs yourself brings up many queries. Here are answers to some frequently asked questions:

How deep should stair treads be?

10 to 14 inches is the recommended tread depth for standard residential stairs. This provides a comfortable surface for the foot while ascending and descending.

Can you make stairs without a carpenter?

With good DIY skills, basic tools, and patience, it’s possible for a non-carpenter to build functional stairs with purchased lumber. Understanding proper layout, assembly, and building codes is key.

What is the best wood for outdoor stairs?

Pressure-treated pine and cedar are excellent woods for outdoor stairs in most climates. They resist moisture, decay, and insects well. Redwood and teak are also very durable options.

How high should a railing be on stairs?

Typical building code specifies a minimum of 34 to 38 inches above the stair nosing for residential handrails and guardrails. This provides sufficient height for support and safety.

Can you build stairs over existing stairs?

Yes, it’s possible to build new stairs over or within an existing stairwell. This requires careful planning and construction to integrate with the original framework. Building permits are usually required.

How do you calculate stair rail length?

To find the length of railing needed, measure the length of the stairs from top riser to bottom. Then multiply this run length by 2 (for both sides) and add the width of the top and bottom rail sections.

Can I make winding stairs?

Winding stairs turn 180 degrees using a narrowed, wedge-shaped tread. This more complex stair style requires intricate carpentry skills and planning to construct safely.

Final Thoughts

Constructing your own staircase is an ambitious project, but with the right techniques and diligence, it can absolutely be a DIY job. Carefully plan out all your measurements, select suitable materials, build a sturdy framework, and take precautions at every step. The end result will be an eye-catching staircase tailored exactly to your space and needs. With each step, you’ll gain valuable carpentry skills and the satisfaction of having conquered this challenging build. Just be sure to follow codes, use common sense, and work carefully. Soon you’ll be walking up your hand-built stairway with confidence.
