A Lightweight, Stable and Customisable Structure for Your Indoor Staircase

Central Stringer Staircases: Benefits, Aesthetics and Customisation

Central stringer staircases offer a modern and elegant solution for indoor staircases in detached houses and apartments.
Their appeal is not a passing trend, but rather the result of three key advantages:

• aesthetics
• functionality
• design freedom
  A single central stringer provides a stable structure while maintaining a visually lightweight appearance, making it particularly well suited to open-plan living spaces.
  These indoor staircases are increasingly regarded as a central element of interior design, rather than simply as a means of connecting one floor to another.
  When carefully designed, they enhance the character of a home, structure the space and introduce a distinctive visual rhythm.

What Are Indoor Staircases with a Central Stringer?

The structure is based on a single stringer running along the central axis of the staircase.
This stringer carries the load and serves as the supporting base for the steps.
The absence of side stringers gives these indoor staircases a lighter and more open appearance compared with concrete staircases or conventional structural systems.
The risers remain clearly visible, while the open spaces between the steps further enhance the airy visual effect.

Different Manufacturing Technologies

The central stringer can be manufactured using different solutions:

• monolithic or modular metal structure
• monolithic or modular wooden stringer
  Each solution creates a different visual effect and offers a range of design possibilities.

Key Benefits of Indoor Central Stringer Staircases

One of the main advantages is their versatility.
These staircases work equally well in contemporary homes and in more understated interiors where harmony and proportions are the primary considerations.

Main Benefits

• lightweight visual appearance without a bulky structure
• improved access to natural light within the interior
• extensive freedom in the choice of steps, balustrades and finishes
• possibility of creating straight, curved or quarter-turn staircases with landings
• possibility of creating spiral-flight staircases
• design adapted to the interior, rather than the interior being designed around the staircase
  A well-designed indoor central stringer staircase does not dominate the space. Instead, it integrates naturally with the surrounding interior while adding both character and architectural value.

Faro Model — Monolithic Central Metal Stringer with Treatment and Platform Options

The Faro model is based on a monolithic central metal stringer, providing a high level of structural rigidity and stability. This solution is particularly well suited to homes where the indoor staircase is visible from the living room or hallway.
The monolithic structure allows for:

• the use of turning steps
• a slender profile that highlights the technical character of the indoor staircase
• a wide range of layout options, even where load-bearing walls are not available
  Visually, the Faro model combines modernity with balanced proportions. The stringer can remain a prominent structural feature or be given a more refined appearance depending on the choice of colours for the structure and steps.
  This model works equally well with wooden steps, as well as with glass or steel balustrades, offering extensive possibilities for creating a cohesive and contemporary interior.

Revo Model — Indoor Staircases with a Solid Monolithic Metal Stringer and Landings

The Revo model combines everyday comfort with a distinctive, high-end design. Built around a solid monolithic metal stringer, it is particularly well suited to indoor staircases with landings, especially for upper floors.

Advantages of Landings

• improved ergonomics
• better organisation of the staircase layout
• a more refined and presentable overall appearance
  The Revo is a popular choice for premium interiors, where timeless design meets everyday comfort. Its staircase geometry is clear and elegant, without unnecessary decorative elements.

Formia Model — Modular Wooden Stringer

The Formia model is designed for those who want a central stringer indoor staircase that combines natural materials with a warmer, more inviting atmosphere. The modular wooden stringer gives the staircase a completely different character from a metal structure.
This model:

• integrates perfectly into Scandinavian and contemporary interiors
• complements wooden flooring harmoniously
• transforms the staircase into a genuine piece of furniture rather than simply a technical structure

Visual Appearance and Interior Integration

Central stringer indoor staircases have a significant influence on the overall atmosphere of a space.
Key factors include:

• the proportions of the stringer
• the thickness and material of the steps
• the method used to attach the balustrade
• the choice of colours for the structure
  Each model can be customised to suit a specific interior. The staircase is designed around the room layout, ceiling height and architectural style of the home.
  This approach avoids having to compromise between aesthetics and functionality.

Summary

Central stringer indoor staircases combine modern aesthetics with extensive design freedom. Models such as Faro, Revo and Formia demonstrate the wide range of results that can be achieved based on the same fundamental concept.
The final appearance depends on the materials, proportions and integration of the staircase within the interior, rather than on a single rigid design.
