A Staircase Comes Out of the Closet: A Complete Guide to Open Stair Remodeling

When a cramped, enclosed staircase dominates the center of a home, it does more than waste valuable square footage. It stifles natural light, blocks sight lines between living areas, and makes daily movement feel like navigating a maze. For many homeowners, the staircase is an afterthought, a purely functional element that connects floors without contributing to the overall design of the house. Yet a well-executed stair remodel can transform. A comprehensive resource on staircase design and construction covers everything not just the vertical circulation of a home but the entire character of its interior. The right staircase becomes a sculptural centerpiece, a defining architectural gesture that sets the tone for every room it touches.

Whether you are dealing with a dark, narrow stairwell from the 1960s or a modern layout that simply feels disconnected, opening up the staircase and treating it as a design feature rather than a utility brings profound benefits. The concept is not new. Architects have long recognized that stairs can serve as the visual and social heart of a home, a place where levels merge and families naturally gather. This article explores how to plan, design, and execute a staircase transformation that elevates your entire home.

Assessing Your Existing Staircase and Structural Constraints

Before you can design a striking new staircase, you must understand what you are working with. Every stair remodel begins with a thorough assessment of the existing structure, the available space, and the building code requirements that will govern your project.

Evaluating the Current Layout

Older homes, particularly those built before the 1980s, often feature enclosed staircases tucked into narrow hallways or wrapped around utility closets. These stairs were designed for efficiency, not experience. The first step is to identify what is really there. Measure the total rise, the available run, and the headroom clearance at every landing. Look for load-bearing walls that surround the stairwell, as removing them will require structural reinforcement.

Key Measurements to Take

  • Total vertical rise from finished floor to finished floor
  • Available horizontal run (the length the staircase can travel)
  • Headroom clearance at the lowest point of the stairwell
  • Width of the existing stair opening between walls
  • Location of any HVAC ducts, plumbing vents, or electrical runs within the stair chase

Identifying Load-Bearing Walls and Structural Elements

The walls that enclose a traditional stairwell are frequently load-bearing, especially in two-story homes where the stairwell shaft provides lateral bracing for the floor system above. Removing or modifying these walls is not a task for guesswork. Consult a structural engineer to evaluate the framing and specify a transfer beam or post-and-beam system if necessary. The goal is to open the stairwell without compromising the structural integrity of the house.

Load-bearing wall along stair runParallel to stairs on one or both sidesEngineer-designed beam and column support
Header above stair openingTop of stairwell at second floorVerify sizing; may need reinforcement
Floor joists around stair chasePerpendicular to stair runDouble or sister joists to carry loads
Intermediate landing structureMidpoint of split-level or L-shaped stairsMay need independent support posts

Designing the Open Staircase Concept

Once you understand the structural boundaries, the creative work begins. An open staircase uses transparency, materiality, and spatial connection to make the stair feel like part of the living area rather than a passage hidden from view.

Choosing a Stair Configuration

The shape of your staircase determines how it interacts with the surrounding rooms. A straight run is the simplest to build and the easiest to open up, requiring only the removal of side walls to expose the treads and risers. An L-shaped or U-shaped stair introduces landings that can double as seating nooks or display ledges. A curved or spiral stair makes the boldest architectural statement but requires careful engineering and precise fabrication.

Popular Open Stair Designs

  • Floating stairs: Treads cantilevered from a hidden stringer or wall, creating the illusion of steps suspended in midair. Best suited to contemporary interiors with clean sight lines.
  • Glass guardrails: Tempered glass panels on one or both sides preserve views and light transmission while meeting code requirements for fall protection.
  • Open risers: Eliminating the vertical riser board between treads increases visual lightness and allows light to filter through the stair from above.
  • Mixed materials: Combining a steel stringer with wood treads, or pairing concrete treads with a glass balustrade, adds texture and visual interest.

Integrating the Staircase with Adjacent Rooms

An open staircase does not just connect floors. It connects rooms. When you remove the walls around the stair, the living room, dining area, and entry hall become visually linked. This demands a cohesive material palette. The stair treads, risers, and railing should relate to the flooring and trim of the adjacent spaces. If the main floor uses wide-plank white oak, extend that material onto the stair treads. If the walls are painted a warm neutral, carry that color onto the stair stringers and risers.

Navigating Building Codes and Safety Requirements

No stair remodel can proceed without satisfying local building codes. These codes exist to ensure safe passage between levels, particularly in the event of an emergency evacuation. The International Residential Code (IRC) provides the baseline that most jurisdictions adopt, though local amendments may apply.

Critical Code Parameters

The IRC specifies a maximum riser height of 7.75 inches and a minimum tread depth of 10 inches. All risers within a single flight must not vary by more than 3/8 inch, and tread depth must remain consistent within the same tolerance. Handrails are required on at least one side of stairs with four or more risers, and the handrail height must be between 34 and 38 inches measured vertically from the stair nosing.

Guardrail Requirements for Open Sides. Understanding the goal of a finished railing is essential before selecting your balustrade system

When the staircase is open on one or both sides, guardrails are required wherever the drop exceeds 30 inches. The guardrail must withstand a concentrated load of 200 pounds applied at any point. Balusters must be spaced so that a 4-inch sphere cannot pass through, a dimension that prevents children from slipping through the openings. Glass panels used as guardrails must be tempered or laminated safety glass with a minimum thickness of 1/4 inch.

Fire Safety and Egress Considerations

In multi-story homes, the stairwell functions as a primary means of egress. If you are removing walls around the staircase, be aware that some local codes require stairwells to be enclosed with fire-rated construction in homes above a certain size or number of stories. An open stair concept may require an alternative means of egress, such as a secondary exterior stair or a properly sized egress window on the upper floor. Check with your local building official before finalizing your design.

Executing the Remodel: From Framing to Finish

With the design approved and permits in hand, the execution phase requires coordination between structural work, finish carpentry, and the installation of railing systems. A well-planned sequence prevents costly rework and ensures a professional result.

Structural Modifications and Rough Framing

The first phase involves removing the old staircase and the enclosing walls. Protect the surrounding floors and furnishings with heavy-duty dust barriers. Once the old structure is gone, install the new beams, posts, and headers specified by the engineer. The new stair stringers are cut and installed. For detailed guidance on correcting framing issues, see our article on fixing rough framed stairs, followed by the rough treads and risers. At this stage, the staircase is walkable but unfinished.

Finish Carpentry and Material Installation

The finish phase transforms the rough frame into a polished feature. Start by installing the finished treads and risers using construction adhesive and finish nails. If you are using a hardwood species such as white oak, ash, or hickory, allow the material to acclimate in the home for at least 72 hours before installation. Stair skirtboards are installed along the walls, cut with precise angle transitions at each tread and riser intersection. Proper techniques for installing stair skirtboards ensure a professional finish.

Railing and Balustrade Installation Steps

  1. Mount the newel posts at the base, top, and any intermediate landings of the stair, anchoring them through the finished floor into the structural framing below.
  2. Install the handrail, joining sections at turning points with concealed dowel or metal connector fittings.
  3. Set balusters at the calculated spacing, ensuring no gap exceeds 4 inches. Use a consistent reveal at both the tread and handrail connection.
  4. If using glass panels, install the bottom channel and top clamp system, then set the glass panels with neoprene gaskets to prevent metal-to-glass contact.
  5. Apply finish (stain, oil, or paint) to all wood components, taking care to protect glass or metal elements from overspray.

Lighting the Staircase

A great staircase deserves great lighting. Recessed step lights installed into the stair riser at each tread provide gentle illumination for safe nighttime navigation. Linear LED strips mounted under the handrail or along the wall stringer create a dramatic floating effect. A pendant light or chandelier hung in the stairwell draws the eye upward and emphasizes the vertical space. Install all lighting on dimmer controls so the stair can shift from bright task lighting during the day to soft ambient glow in the evening.

Transforming a cramped, forgotten staircase into an open, light-filled architectural feature is one of the most rewarding projects a homeowner can undertake. The process demands careful planning, structural know-how, and attention to code requirements, but the result is a home that feels larger, more connected, and infinitely more inviting. Whether you choose floating treads with glass railings or a classic wood stair with sculptural newel posts, the investment pays dividends in both daily enjoyment and property value. Every time you walk up those stairs, you will experience the difference that thoughtful design makes.
