Classification of heights and types of buildings with different numbers of storeys

Any city’s skyline is made up of a wide range of structures that are varying in size and shape. These structures can be anything from tiny one-story homes to enormous skyscrapers that appear to reach the sky. Anyone working in construction or urban planning must comprehend how buildings are categorized according to their heights and number of stories.

Structures are frequently classified according to how many floors they have. Their function, style, and building techniques can all be better understood thanks to this classification. Low-rise structures, which usually consist of one to three stories, are frequently used for residential uses, including homes and modest apartment complexes. These buildings are frequently seen in suburban areas and are reasonably easy to build.

Mid-rise structures, which typically consist of four to twelve stories, are used for many different things. They can be mixed-use, which combines living areas with retail and office space, or residential. To ensure stability and safety, these buildings require more sophisticated construction methods and materials.

Towering structures that reach up to twelve stories are incredible feats of contemporary architecture. They are mostly found in urban areas where there is a high demand for housing and office space and a limited amount of available space. To ensure that these structures can withstand natural forces like wind and earthquakes, intricate planning and the application of cutting-edge technology are used during construction.

Lastly, there are skyscrapers, which are exceptionally tall structures that frequently have more than fifty stories. These buildings, which stand for contemporary architectural accomplishments, call for innovative building materials and methods. Skyscrapers are more than just structures; they are symbols of a city’s identity.

Anyone working in construction has to understand these classifications because every kind of building has different needs and difficulties. Your project will succeed if you understand the differences between low-rise, mid-rise, high-rise, and skyscrapers, whether you’re designing a new house or a tall office building.

Classification of heights and types of buildings with different numbers of storeys

The length of each interfloor overlap and the distance from the floor to the ceiling of each floor must be taken into consideration when calculating the overall height of a house, building, or other structure. They will also be counted as separate floors if the basement rises above the ground by more than 2 meters and the attic space is wider and higher than 1.6 meters. The FSGR, cadastre and cartography No. 4200-AB / 20, dated 12.05.2020, provides an explanation of this in the Rosreestr explanations. One such letter is titled "On the number of floors of individual housing construction projects."

A succinct general classification of building heights and storey counts:

• Low-rise. Number of floors – from 1 to 3. Maximum house height – up to 12 m.
• Mid-rise. Floors – from 3 to 5. Building height – up to 15 m (standard 5-story building).
• High number of storeys. From 6 to 10 floors. The highest height is 30 m.
• Multi-storey. Number of floors – 10-25. Permissible height is grouped by building category.
• High-rise. Floors – from 25 to 30. Height starts from 100 m or more.

Depending on their classification, multi-story building height groups:

• Category I (houses with a maximum number of floors – 17-18) – total height no more than 50 m;
• Cat II. (up to 20 floor.) – height up to 75 m;
• III cat. (25th floor.) – up to 100 m high.

For instance, a fifteen-story, category II multi-story building is roughly 55 meters tall. The Lakhta Center in St. Petersburg is the tallest structure in all of Europe and Russia, according to records for 2020. It is 463 meters tall. This is much higher than the structures in the "Moscow City" complex, which houses the highest buildings in Moscow. However, a massive skyscraper in Dubai (UAE) is the tallest structure in the world. The structure is known as the "Burj Khalifa," has 163 stories, and rises to a height of 828 meters above the ground.

In the construction industry, buildings are frequently grouped according to their height and number of stories; these can range from single-family homes, which are low-rise structures, to tall skyscrapers. Knowing these classifications aids in planning, designing, and enforcing regulations, guaranteeing that every building satisfies particular standards for functionality, safety, and aesthetics. For architects, builders, and anybody else involved in construction and urban development, understanding the differences between various building types is crucial, regardless of the building type—a cozy two-story home or a high-rise office complex.

Identification of a low-rise building

Criteria used to categorize low-rise buildings:

• Location. They are built outside the city, in summer cottages, garden villages, within the city with high, medium or low population density or in a settlement with the status of “village”.
• Status. Distributed by class, quality of life – economy, middle class, business, luxury homes.
• Accommodation. Frequency of use – capital construction (permanent residence), seasonal (for non-regular residence).
• Options. Land area for one house – up to 0.15 hectares. Availability of a garden, vegetable garden, outbuildings (outbuildings, basement, woodshed, barn, etc.).
• Number of storeys. Number of floors – 1-3.
• Construction materials. Buildings are divided according to the type of building material used into the following: panel, wooden, block, monolithic, brick or combined (for example, block and wood).
• Non-residential areas. There must be non-residential areas in the house – veranda, attic, extension (summer kitchen), basement.
• Additional buildings. The site must have temporary or permanent additional buildings – outbuildings, bathhouse, sauna, garage, greenhouse, winter garden, summer kitchen, barbecue, etc.

Names for homes with three stories or more can vary based on how they are used:

• individual, detached house;
• cottage;
• duplex;
• apartments;
• country house;
• townhouse;
• villa;
• estate;
• mansion;
• residence.

The height of a single floor in an apartment building is limited in modern construction projects to 2.8 to 3.3 meters. Individual houses are given the lowest rooms (IZhS). In this case, the rooms’ height shouldn’t be lower than the allowed 2.5 meters, per SNiP. If not, the home won’t be allowed to be listed as residential. Low-rise building materials include brick, foam blocks, reinforced concrete slabs and panels, and wood (logs, timber frame).

Anyone working in construction or maintenance needs to understand how different building types and heights are categorized according to the number of stories. Structures that are classified as low-rise, mid-rise, or high-rise are commonly known as buildings. Low-rise structures are perfect for small-scale commercial and residential spaces because they typically have three stories. These structures provide an affordable option for many construction requirements because they are comparatively easy to construct and maintain.

Mid-rise structures are typically found in urban settings and have four to twelve stories. These structures offer a compromise between construction costs and space efficiency. They frequently contain offices, apartments, and mixed-use projects, which enhance the vibrancy and density of urban life.

Modern skylines are characterized by high-rise structures, which are structures with more than twelve stories. In densely populated areas, these structures are designed to maximize available space. To guarantee stability and safety, they need cutting-edge engineering. With their expansive amenities and panoramic views, high-rise structures are frequently used as office towers, opulent apartments, and hotels.

From low-rise to high-rise, every kind of building is important in forming our built environment. The intended use, location, and budget are just a few of the variables that influence the choice of building height and type. Builders and developers can make well-informed decisions that satisfy both functional requirements and aesthetic preferences by being aware of these classifications.
