Internal masonry stairs: what you need to know

Internal masonry stairs represent a choice of great aesthetic and functional impact. Often preferred to other building solutions in new construction projects. They are less common in renovation works, internal transformations, and the replacement of existing stairs to meet new living and aesthetic needs and in the case of restoration. In these cases, it is almost always preferable to opt for lightweight prefabricated stairs.

Currently, there is a greater tendency towards prefabricated stairs due to the speed of execution, less visual impact, and the ease of assembly and disassembly in case of future transformations of internal spaces. On the other hand, masonry stairs are still preferred for their sturdiness and structural safety. Furthermore, they facilitate vertical connections between floors during the construction phase, thus making the work of the laborers easier and safer, as they are cast in place with the structure, unlike prefabricated stairs that are generally installed during more advanced stages of construction.

Aesthetically, masonry stairs can take on various shapes (L-shaped, U-shaped, spiral, scissor, etc.) and can be finished with different materials, such as tiles, wood, metals, or more innovative materials like micro-cement or resin, making them versatile and suitable for various furnishing styles.

However, both the construction and potential removal of internal masonry stairs require a significant economic and time commitment. Furthermore, masonry stairs require larger spaces and specialized labor for both the structural realization and the finishing part. Despite higher costs and longer timelines, an internal masonry stair offers a feeling of solidity and can enhance spacious environments without appearing bulky. Even in minimalist contexts, it can harmoniously integrate with carefully chosen furnishings and materials.

The construction of internal masonry stairs involves the use of various materials and techniques to ensure durability, aesthetics, and functionality.

When is it advisable to choose internal masonry stairs?

The suitability of a masonry staircase mainly depends on the stage of the construction intervention and the characteristics of the property. Being a solution that involves significant masonry and structural work, its incorporation should be evaluated during the early design phases.

New construction

New construction represents the ideal context for creating internal masonry stairs. At this stage, the designer can integrate the staircase within the structural system of the building, optimizing space, distribution pathways, and the relationships between different areas.

The design freedom is maximized: it is possible to define the shape, floor plan development, width of the flights, and size of the landings without the constraints imposed by existing structures. Furthermore, costs are generally lower compared to a later insertion, as the work is carried out concurrently with the rest of the structure.

Major renovation

In comprehensive renovations, especially when working on single-family homes, villas, or duplex apartments, the masonry staircase can represent a particularly effective solution for redefining internal spaces.

When significant structural interventions are planned, such as openings in floors, consolidations, or distribution modifications, the insertion of a new staircase can be designed organically. In these cases, it also becomes possible to utilize the under-stair area as a functional element, integrating cabinetry, technical rooms, or storage spaces.

Replacement of an existing staircase

A new masonry staircase is generally recommended to replace an existing one when the original structure presents functional or structural deficiencies or when its dimensions do not satisfy current comfort standards.

However, the intervention requires thorough checks on the load-bearing capacity of the existing structures. A masonry staircase has a significantly higher weight compared to many prefabricated solutions and may necessitate reinforcement work on the floors or foundations.

When it is not the most suitable solution

A masonry staircase does not always represent the best choice. In interventions characterized by limited space, very short execution times, or limited load-bearing capacity of existing structures, it may be more convenient to opt for stairs made of steel, wood, or mixed systems.

Even in architectural contexts that require maximum visual lightness and transparency, metal structures or suspended stairs often allow for outcomes that are more consistent with contemporary design language.

Pros and cons of internal masonry stairs

Like any construction solution, masonry stairs also have positive aspects and challenges that must be evaluated based on the specific needs of the project.

Advantages of internal masonry stairs

The main strength lies in the structural solidity. A staircase made of reinforced concrete or masonry offers high resistance to loads and a particularly long lifespan.

From an architectural standpoint, it allows for virtually unlimited customization. The structure can be finished with numerous materials and adapted to any style, from classic to minimalist.

Another advantage relates to acoustic comfort. The mass of the structure helps to reduce vibrations and impact noise, improving the perceived quality of the spaces.

The masonry staircase also allows for enhancing the under-stair area, transforming it into a useful space that is perfectly integrated into the design.

Disadvantages of internal masonry stairs

Among the less favorable aspects is primarily the weight of the structure, which requires accurate static checks and may limit applicability in certain existing buildings.

Also, construction times are generally longer than with prefabricated stairs. The work involves structural operations, concrete curing, cladding, and finishes.

Once built, the staircase is difficult to modify. Any future changes involve invasive and costly interventions.

Types of internal masonry stairs

The geometric configuration of the staircase influences not only aesthetics but also comfort, safety, and overall footprint.

Straight flight staircase

It is the simplest and most linear type. It develops along a single axis and ensures high practicality of use.

From a construction standpoint, it is generally the most cost-effective and easiest solution to implement. However, it requires important longitudinal development and therefore adequate space.

L-shaped staircase

The L-shaped staircase involves a change of direction of 90 degrees, usually achieved through a landing or fan-shaped steps.

It allows for better space management and easily adapts to contemporary residential environments, offering a good compromise between comfort and space reduction.

U-shaped or double-flight staircase

The U-shaped configuration develops through two parallel flights connected by an intermediate landing.

This solution allows for reducing the plan footprint while maintaining high levels of comfort and safety. It is particularly suitable for buildings with significant floor-to-floor height.

Curved or spiral masonry staircase

Curved stairs represent one of the most sophisticated expressions of architectural design.

Their construction requires greater complexity and careful structural design but allows for a strong aesthetic impact and significant value enhancement of the spaces.

Cantilever staircase with masonry or reinforced concrete structure

In this configuration, the steps appear suspended and anchored to a load-bearing wall or a reinforced concrete structure.

While maintaining the robustness typical of masonry, this solution offers a much lighter and more contemporary image.

Materials and Structure of Internal Masonry Stairs

The choice of materials directly affects structural performance, costs, and customization options.

Reinforced Concrete

Reinforced concrete is currently the most commonly used material for the construction of internal stairs.

It guarantees high load-bearing capacity, great formal freedom, and excellent durability. Additionally, it allows for the creation of complex geometries and monolithic structures perfectly integrated with the rest of the building.

Bricks, Blocks, and Mixed Systems

In some interventions, lightweight bricks or construction blocks are used in combination with load-bearing reinforced concrete structures.

These systems help reduce weight and costs while maintaining good overall performance.

Stone and Traditional Masonry

In historic buildings or architectural restoration projects, traditional construction techniques based on natural stone and load-bearing masonry can be employed.

These solutions are characterized by high architectural value but require specialized skills during both the design and execution phases.

Structure, Steps, Landings, and Under-Stair Areas

An internal masonry staircase is composed of various elements that need to be designed in a coordinated manner.

The load-bearing structure transfers loads to the floors and foundations, while steps and landings must ensure adequate safety and comfort levels. Special attention is warranted for the under-stair areas, which can become a valuable resource for enhancing the overall functionality of the residence.

Finishes for Internal Masonry Stairs

The structure of the staircase is only the foundation upon which to build the aesthetic identity of the intervention.

Wood

Wood introduces warmth and visual comfort. It can be used in both classical contexts and modern environments due to the wide availability of species and finishes.

Marble and natural stone

Marble, travertine, granite, and other natural stones confer elegance and prestige.

These materials are particularly resistant to wear and enhance the staircase as a representative element of the home.

Porcelain stoneware

Porcelain stoneware is now one of the most versatile solutions thanks to its high technical performance and the wide range of available aesthetic effects.

Resin and microcement

Resin and microcement allow for the creation of continuous surfaces free from joints.

They are particularly appreciated in contemporary projects for their minimal appearance and ability to unify different architectural elements.

Tiles

Tiles continue to represent a common solution due to the variety of formats, colors, and finishes available.

Railings, handrails, and lighting

Railings and handrails should not be considered merely safety elements. Their design significantly contributes to the final image of the staircase.

Lighting also plays an increasingly important role. Integrated LED systems in the steps, handrails, or walls help to improve safety and the perceptual quality of the spaces.

How to design internal masonry stairs with BIM

BIM design allows the staircase to be developed as a parametric object integrated into the digital model of the building.

Through BIM, it is possible to automatically verify dimensions, slopes, interferences, and regulatory requirements even in the preliminary phases of the project. The three-dimensional model also facilitates coordination between architects, structural engineers, and contractors, reducing errors and variations on site and forming the starting point for modeling and structural calculations.

The use of BIM design software also allows for the generation of graphic documents, metric calculations, and realistic visualizations directly from the information model, improving control over the entire design process.

How to use artificial intelligence to generate ideas and design variants

Artificial intelligence is introducing new ways to support architectural design, including for internal masonry stairs.

Through generative AI tools, it is possible to quickly produce concepts and alternative design solutions, explore different geometric and functional configurations, compare materials and finishes, or generate photorealistic images useful in the preliminary phases of comparison with the client.

Integrated within BIM processes, AI can support the analysis of design solutions, suggest dimensional optimizations, and contribute to the evaluation of numerous variants in extremely reduced times. The designer maintains a central role in technical and architectural choices but has an additional tool capable of expanding design exploration possibilities and accelerating the decision-making process.

How much does it cost to build internal masonry stairs?

The cost of internal masonry stairs varies depending on the materials used, the labor of the workers, and design choices.

In general, at the same degree of complexity and finishing materials, masonry stairs cost about 30% more than prefabricated stairs. Furthermore, the construction times are generally longer, especially in the case of reinforced concrete stairs, where the construction times are also linked to the concrete curing period, the assembly and disassembly of the formwork, the installation of the reinforcement, etc.

In prefabricated stairs, all these steps are not necessary, and it is only required to assemble the various pieces that have arrived on site, depending on the type of construction chosen by the designer and shared with the client (wood, steel, glass, etc.).
