If you have ever explored historical homes in New England, browsed through unique architectural designs online, or delved into the eccentric world of tiny house building, you might have stumbled upon a bizarre and steep type of staircase. Known colloquially as witches stairs, these peculiar structures look like half-cut steps that force the climber to alternate their left and right feet meticulously. But what exactly are they, and why are they associated with witchcraft?
In this comprehensive guide, we will dive deep into the intriguing history, spooky folklore, and practical modern applications of witches stairs. Whether you are an architecture enthusiast, a lover of colonial history, or someone looking to save floor space in a cramped loft, understanding the mechanics and myths behind these alternating treads is an absolute must.
What Are Witches Stairs?
At their core, witches stairs—technically known in the architectural and construction world as alternate-tread stairs—are a highly specialized type of staircase designed to fit into extremely tight spaces. Unlike traditional staircases, which feature wide, rectangular treads that span the entire width of the stairwell, alternate-tread stairs are constructed with staggered, half-width steps.
When you look at alternate-tread stairs from the bottom up, you will notice that the left step and the right step are offset. To ascend or descend, you must begin with the correct foot and alternate perfectly. If the bottom step is on the right, you must lead with your right foot. If you try to step with your left foot first, you will find empty air or a severely truncated ledge. This unusual staircase design allows the stairs to be built at a much steeper angle than standard stairs—often resembling a hybrid between a ladder and a traditional staircase—while still providing enough depth for the human foot to land safely.
The Spooky Folklore: Can Witches Climb Stairs?
The most captivating aspect of these structures is undoubtedly their name. The term witches stairs stems from old New England folklore, particularly surrounding areas famous for their supernatural history, like Salem, Massachusetts. According to local legends and colonial superstitions, a witch cannot easily climb up or down a set of alternate-tread stairs.
The myth suggests that witches, perhaps hindered by their magical nature, lack the fine motor skills, balance, or mental coordination required to navigate the complex, staggered footwork of the alternating steps. Another version of the legend claims that a witch’s broomstick would get caught in the steep, cramped enclosure, preventing her from reaching the upper floors of a home. Consequently, paranoid homeowners in the 17th and 18th centuries supposedly installed these confusing staircases as a protective ward to keep witches from sneaking into their bedrooms at night.
While it is a fantastic story perfect for a Halloween night, historians and architectural experts have thoroughly debunked the myth. There is no historical evidence to suggest that colonial Americans built these stairs to deter practitioners of the dark arts. Instead, the name witches stairs is likely a much more modern invention—a whimsical, retroactively applied moniker meant to explain a bizarre architectural feature that contemporary people found strange and slightly dangerous.
The Real Reason Witches Stairs Exist: Function Over Folklore
If witches stairs were not built to keep out supernatural intruders, why do they exist at all? The answer is simple: space conservation.
In older homes, particularly small colonial cottages or densely packed urban row houses, interior space was at an absolute premium. Traditional staircases require a significant amount of horizontal space—known as the “run”—to achieve a safe and comfortable vertical rise. If a builder simply increased the angle of a standard staircase to make it fit into a smaller footprint, the treads would become too shallow, leaving only enough room for a person’s heel or toe. Climbing such a staircase would be incredibly hazardous, akin to scaling a steep cliff face.
This is where the genius of the alternate-tread staircase comes into play. By removing half of the tread on each step, builders effectively doubled the usable depth for each individual foot without extending the overall horizontal footprint of the staircase. This allowed for a much steeper incline—sometimes approaching 60 to 65 degrees, compared to the standard 30 to 40 degrees of normal stairs—while still offering a secure, full-depth landing pad for each footstep.
The Ergonomics and Biomechanics of Alternate-Tread Stairs
To truly appreciate witches stairs, one must understand the biomechanics of how humans climb. When you walk up a normal flight of stairs, you only use the left half of the step for your left foot and the right half for your right foot. The opposite half of the tread is essentially dead, unused space during that specific stride.
The alternate-tread design merely cuts away that unused portion. While it visually appears confusing, your body naturally adapts to the rhythm. The primary challenge lies in the strict sequence. You cannot hesitate, change your leading foot mid-climb, or easily stand with both feet on the same level. This rigid requirement for mindful navigation is a major reason why these stairs are considered both a marvel of efficient engineering and a potential safety hazard.
Pros and Cons of Witches Stairs
If you are considering incorporating this unique architectural feature into a tiny home, cabin, or loft space, it is crucial to weigh the advantages against the significant drawbacks.
The Advantages of Space-Saving Stairs
- Ultimate Space Efficiency: The primary benefit is the drastic reduction in the floor space required. Witches stairs use about half the square footage of a traditional staircase.
- Safer Than a Ladder: While steeper than normal stairs, they are generally safer and more comfortable to use than a flat ladder, as they provide a deeper tread for the foot to rest on.
- Unique Aesthetic Appeal: There is no denying that alternate-tread stairs are a fantastic conversation starter. They add a quirky, historical, or distinctly modern minimalist vibe to any interior design.
The Disadvantages and Safety Risks
- Steep Learning Curve: They require active thought to use. Guests, young children, and the elderly often struggle to navigate the alternating pattern safely.
- Carrying Items is Dangerous: Trying to move bulky furniture, carry a heavy laundry basket, or even hold a cup of hot coffee while ascending or descending witches stairs drastically increases the risk of a severe fall.
- No Room for Error: If you misstep or lose your balance, there is very little tread area to catch yourself, leading to potentially dangerous accidents.
Are Witches Stairs Legal? Building Codes and Regulations
Because of the inherent safety risks, you cannot simply install witches stairs wherever you please. In most modern jurisdictions, the International Residential Code (IRC) strictly dictates how and where alternate-tread stairs can be used in a home.
Under standard building codes, witches stairs are almost never permitted as the primary means of egress (the main exit or access route) for a dwelling. You cannot use them to connect the main living floor to the primary bedrooms or front doors. However, they are often legally permitted for secondary or limited-access areas. For example, building codes frequently allow them to be used to access small, non-habitable spaces like a storage loft, an unfinished attic, or a small mechanical room.
In commercial and industrial settings, organizations like OSHA (Occupational Safety and Health Administration) have specific guidelines allowing alternate-tread stairs in places where a traditional staircase won’t fit, but where a regular ladder would be too unsafe for workers carrying tools.
Modern Applications: Should You Install Witches Stairs?
Today, witches stairs are experiencing a massive resurgence in popularity, largely driven by the tiny house movement and urban micro-apartments. When living in a house that is only a few hundred square feet, dedicating a large chunk of the floor plan to a staircase is out of the question. For tiny house owners, the choice often comes down to a vertical ladder, a spiral staircase, or an alternate-tread staircase.
While spiral staircases are visually appealing, they can still eat up a surprising amount of floor space and make moving furniture nearly impossible. Witches stairs provide a brilliant compromise. Furthermore, modern architects have adapted the design to include hidden storage compartments inside each alternating step, maximizing utility in compact homes.
If you plan to build an alternate-tread staircase, ensure you install sturdy, dual handrails. Because the footing is unusual, having continuous support for both hands is an absolute necessity to prevent falls. Additionally, consider texturing the treads to provide maximum grip, especially if the stairs will be navigated in socks or bare feet.
Conclusion
The legend of witches stairs is a testament to how human imagination tries to explain the unusual. While they won’t actually protect you from the magical curses of a 17th-century sorceress, these fascinating staircases remain a brilliant solution to an age-old architectural problem. By blending historical necessity with modern space-saving design, witches stairs continue to captivate homeowners, builders, and storytellers alike. Whether viewed as a quirky piece of folklore or a functional design element for a tiny house, they prove that sometimes, the most peculiar designs are born out of pure, unadulterated necessity.
