“Carpet Area & Built Up Area: Myths Explained”

Leave a comment

Carpet area, built-up area, plinth area, and super built-up area are crucial terms when buying a home, with each offering different insights into the true size and usable space within a property. Carpet area refers to the usable floor space inside a home, excluding the walls, while built-up area encompasses the carpet area along with the thickness of the walls and additional spaces like balconies. Understanding these terms is essential, especially for civil engineers who need to adeptly interpret floor plans. This article will delve into these different types of areas, providing clarity on the actual dimensions of a property, including the distinction between built-up area vs carpet area.

Real Estate Regulation and Development Act, 2016, (RERA)

The Real Estate Regulation and Development Act, 2016, (RERA) is an act established by the Indian parliament. However, the main objective of RERA is to give prompt information between the buyers and sellers. This increases transparency and reduces the chance of cheating.

There are three different ways to calculate the area of the property. 

  • In terms of the Carpet area
  • In terms of Built-up area
  • In terms of Super built-up area

While buying a property buyer should pay for the area which is usable. RERA provides safety of money, buyer protection and balanced agreement.

Types of areas in Building Construction

Before making home buying plans, we should familiarize ourselves with the following building construction practices and terminologies typically used in the industry.

  • Plot area
  • Built-up area or Plinth area
  • Carpet area
  • Setback area
  • Super built-up area

Before getting into these terms first we have to know what is RERA 

Plot area (Areas of building)

The plot area includes the complete area which you own. This area comes under the fencing.

Plot-area
Plot-area

Carpet area (Areas of building)

Real estate agents frequently use the term “carpet area,” which refers to the floor area of a building that can be covered with carpet. This area, also known as the net usable floor area, is crucial for determining the actual space available for use in a property.

Carpet-area
Carpet-area

Carpet Area = Total floor area – Area of internal/external walls

But as per RERA Carpet area = Total Floor area – Area of external walls

According to RERA flats should be sold on the basis of carpet area. The carpet area as per RERA is the area of usable spaces such as bedrooms, kitchen, bathroom, toilet etc. It also includes an area covered by internal partition walls. It excludes areas such as Balcony, utility areas, external walls area, open terrace area, lift, lobby, staircase etc. Generally, carpet area is 70% of its built-up area. 

Built up area

The plinth area is also known as the Built-up area. Basically, It is the total area of the building within the plot area. It is mostly 30% of the total plot area. 

Plinth-area
Plinth-area

Built-up Area = carpet area + Area of walls

It includes living room, bedrooms, utility, bathroom, wall thickness, kitchen, balcony closed staircases etc. and excludes open terrace area, lift, open staircase, swimming pool etc. It is 10 to 15 % more than the carpet area.

Built up area vs carpet area

Built-up area vs. carpet area are important terms in real estate that describe different aspects of a property’s space. Carpet area refers to the actual floor area inside the walls where you can place carpet or furniture. It includes rooms like bedrooms and kitchens but excludes areas like balconies and walls.

Built-up area, on the other hand, includes the carpet area plus the space taken up by walls and other building parts. This means it covers all enclosed spaces within the building, including walls, corridors, and partitions. Built-up area is typically larger than the carpet area by about 10% to 15% because it counts everything inside the building’s outer walls.

Knowing the difference between carpet area and built up area is important for homebuyers. Carpet area tells you exactly how much livable space you get, while built-up area gives you a broader view that includes all internal structures. This understanding helps buyers make informed decisions about the space they’re getting in a property.

Super built-up area

Super built-up area was used to measure the area of property before the RERA act came into existence. Because the super built-up area lowers the rate per square foot. Saleable area is another name of super built-up area.

Super built up area

Super Built-Up Area = Setback area+Built-up Area+20% of common area 

Super built-up area includes common areas like swimming pool, clubhouses, lobby, staircase, Lift, etc. and the built-up area of the flat. 

Set back area

Set back area is the space between the boundary and the building. It is the minimum open space necessary around the building. As per the municipal regulation a specific margin should be provided between building and road. 

Setback-area
Setback-area

Setback area = Built-up Area – Plot area

This provides sufficient ventilation, ease in vehicle movement and protection from other entities

Key Takeaways:

Understanding the differences between carpet area, built-up area, and other terms like super built-up area is crucial when buying a property. Carpet area specifically denotes the usable floor space inside the walls, while built-up area includes everything within those walls, including partitions and corridors. RERA guidelines emphasize selling flats based on carpet area, ensuring transparency and fair pricing. Super built-up area, now less common due to RERA, includes common areas like lobbies and lifts, affecting overall cost calculations. Setback area refers to the open space required around a building, ensuring adequate ventilation and safety margins.

Conclusion:

  • Carpet Area:
    • The space inside walls where you can put furniture.
    • It’s the actual usable living area.
  • Built-Up Area:

What is a Plinth beam? Plinth beam height and size

Leave a comment

What is a plinth beam in construction? Plinth beams are horizontal structural elements that are built at the plinth level. It is the first beam built after the foundation has been completed. Furthermore, the plinth beam is an important component in a building because it serves as a foundation for brickwork as well as a moisture barrier, preventing moisture from entering the superstructure walls. The height of the plinth beam is typically 200mm to 450mm. It can be both reinforced and unreinforced.

The most important components of a building are the substructure and superstructure. The substructure is the part of the building that is below ground level, while the superstructure is the part of the building that is above ground level. The plinth level separates the substructure from the superstructure. The plinth beam follows the foundation’s construction. This article discusses what a plinth beam is, as well as plinth level, plinth beam size, and plinth beam height.

What is a plinth?

The plinth is the structural stratum that separates the superstructure and substructure of a building. All structures must have a ground floor that is 45 to 60 centimetres higher than the surrounding ground. This will prevent rainwater, dirt, and dust from entering the building. Because of this, the outer dimensions of a pedestal constructed first are slightly larger than those of the ground floor. That is referred to as the Plinth. A level or base known as a plinth is used to support superstructure walls, columns, and other structures. The plinth’s function is to distribute pressure and load evenly across a surface.

What is a plinth beam?

A plinth beam, as the name implies, is a beam at the plinth level. It is a particular kind of beam that is situated at the bottom of a framed structure. Because it holds the columns in place, it is also referred to as a Tie Beam. A horizontal structural component that joins the columns at the plinth level of the building is called a plinth beam. It is constructed above the top of the plinth level in load-bearing walls to aid in uniform load distribution and building settlement. Plinth beams reduce the length and slenderness ratio of a column. These beams are installed to prevent foundation cracks from spreading into the structure.

The plinth beam is located at 1.5 to 2 ft above Ground Level
Plinth Beam

Plinth beams are installed to stop cracks from the foundation from spreading into the wall above when the foundation settles. Plinth beams distribute the load of the wall evenly over the foundation.

Plinth beam in construction – Functions and advantages

Following are the functions and advantages of plinth beams

  • To prevent the development of cracks from the foundation to the walls
  • For distributing loads uniformly from columns to the foundations via superstructure.
  • Prevention of differential settlement
  • To prevent the entry of dampness in the structure. 
  • For avoiding the collapse of building due to earthquakes. It is crucial to provide plinth beams in earthquake-prone areas.
  • For providing support for walls
  • To reduce the effective length of columns. 
  • Prevention of column buckling
  • To withstand lateral forces. 
  • It saves buildings by preventing differential settlement which is caused by the partial failure of substructure or by the failure of soil on which buildings are constructed.
  • It provides uniformity to buildings at the plinth level.
  • The best application of a plinth beam is to withstand outside actions such as water, tree roots, and termites which could affect the life of the plinth.
Plinth beam
plinth beam

Size of plinth beam

The plinth beams are designed in accordance with IS 132920-2016. According to the IS Code, the minimum width of the plinth beam cannot be less than 250mm. The depth should be not more than 1/4 of the clear span and not less than 200mm depth. In addition, the span to overall depth should be between 15 and 18. The concrete strength of the plinth beams shall not be less than 200Mpa.

Plinth Beam
Plinth beam

Plinth beam reinforcement

At the bottom of the beam, two bars with a minimum diameter of 12mm are recommended. Similarly, two bars with a minimum diameter of 10mm must be provided at the top of the plinth beams. A 25mm concrete cover should be used to protect reinforcement bars. The stirrup diameter should be at least 6mm, with a 15cm spacing.

Plinth beam construction

1) Determining the mark-up width First, the plinth level is marked. Plinth beams are usually half the width of the foundation. The skeleton is prepared after marking the width of the plinth. The beam reinforcement must then be completed prior to shuttering.

2) Formwork Installation The next step is to put up formwork. Steel, wood, or plastic must be used for formwork. By levelling the ground, you can fix the formwork properly.

3) Concrete pouring Before pouring concrete, make sure the shuttering is dry and all the joints are tight.

4) Pouring of the concrete

Before pouring concrete, ensure the shuttering is dry and all the joints are tight. Pour the concrete evenly. 

5) Curing of the Concrete

After the concrete is dried, It is cured for at least 7 to 14 days for attaining good strength and durability

5) Removal of Formwork

After curing Once the concrete is set, remove the formwork.
