Dimensional Standards Of Building Components
Footing, Column, Beam, Slab, Lintel, Doors, Windows, Sill, and D.P.C., filling up the earth, constructing a parapet wall, and so on are the basic components of a building structure.1. Depth of Foundation
The minimum foundation depth is kept at 1 meter below ground level to avoid weathering impacts and improve stability. The foundation’s width should be such that soil stress is kept within its safe bearing capacity. When a large number of footings are necessary, the depths should be kept as equal as possible.2. The Plinth Of Buildings
3. The Thickness Of Damp Proof Course (D.P.C)
4. The Thickness Of Cement Concrete Floor
The cement concrete floor must be at least 100 mm thick, with a floor finish applied on top. As a floor finish, cement mortar or tiles with a thickness of 10 mm to 20 mm are typically used.5. Height Of Ceiling
6. Sizes of Rooms
Sl no. | Name of Room | Minimum Dimension | Maximum Dimension |
1. | Drawing Room or Living Room | 4200 mm x 4800 mm | 5800 mm x 7200 mm |
2. | Bed Room or Master Bed Room | 3000 mm x 3600 mm | 4200 mm x 4800 mm |
3. | Dining Room | 3600 mm x 4200 mm | 4200 mm to 4800 mm |
4. | Kitchen | 2500 mm x 3900 mm | 3000 mm x 3000 mm |
5. | Bath / WC Combined | 1800 mm x 1800 mm | 1800 mm x 2500 mm |
6. | Bath (Separated) | 1200 mm x 1800 mm | – |
7. | W. C. (Separated) | 1200 mm x 1200 mm | – |
8. | Guest Room | 3000 mm x 3600 mm | 3000 mm x 3000 mm |
7. Sizes of Doors
A residential building’s main entrance door should measure 1000 mm by 2100 mm, and other doors must be at least 900 mm wide and 2000 mm tall. The garage doors are 2500 mm x 2300 mm, while the single–leaf shutter doors for the W.C. and bathrooms are 600 mm to 750 mm x 1800 mm.8. Sizes Of Windows
The Sill level is the starting point for any window in a house or a level where windows are installed. To achieve evenness in all window levels, the sill level is critical. Any house should have a sill level of roughly 3 feet (900 mm). The size of the windows is determined by the overall area of the needed window apertures. It’s important to remember the following guidelines: i) Window width = 1/8 (room width Plus room height). ii) For optimal illumination, windows should have a glass area of 10% to 20% of the room’s floor area. iii) One square meter of window area should be provided for every 30 cubic meters of interior room space. iv) 750 mm x 1000 mm is the standard minimum window size.9. Chajjas
Weather Shed is another name for Chhajjas. This is a structure built above a window that is projected outside from the window face.Dimensional Standards for Chajja:
Chhajjas Length = Window Width + 0.15m Bearing on Both Sides Width of Chhajjas = 0.45 m to 0.60 m10. Ventilators
The size of the ventilator must be at least 1000 mm x 500 mm to ensure enough ventilation for any comfortable room. The bath and toilet should be at least 450 mm x 300 mm in size, and their depth must be more than 450 mm; you have to compromise with privacy.11. Bathrooms And Water Closets
The height of a bathroom ceiling or water closet should be a minimum of 2.1 m (From the floor’s surface to the lowest ceiling point ). A bathroom must be at least 1.8 square meters in size and 1.2 meters wide. The floor area of the water closet must be at least 1.1, and the width must be at least 0.9 m. The floor space must be at least 2.8 m with a minimum width of 1.2 m if a bath and a water closet are combined.12. Staircases
The following are the minimum width, minimum tread width, and maximum riser of staircases for buildings:- In residential construction, the rise = 130 to 190 mm.
- In an office building, the rise =125 and 150 mm.
- For public buildings, the rise =275 mm to 350 mm.
- For residential buildings, the rise =250 to 300 mm.
The thumb guidelines used to select a building’s rise and tread are as follows:
2T X R = 550 to 650 T x R = 39000 to 48000 The width of steps in residential structures is 900 mm, and in public buildings, it is 1000 mm. (Total Floor Height / Riser Height) = Number of Risers The number of treads = the number of risers -113. Lintel Beams
Lintels are made of reinforced concrete, and it is installed over openings in the wall such as doors and windows. The Lintel carries the load that comes through window and door openings. R.C.C. lintel beam thickness ranges from 100 to 250 mm, with 150 mm being the most common.14. R.C.C. Roof Slab
Roofs come in various shapes, although flat and sloped roofs are the most common. Most roofs are made of R.C.C., stone, tiles, and other materials. R.C.C. roof slabs are 100 – 150 mm thick (100 mm is most common), whereas sunshades are 25 – 50 mm thick.15. Parapet Wall
A parapet wall is a low-rise wall that runs along the edge of a roof, terrace, walkway, balcony, or other structure. The parapet wall height above the finished floor level should not be less than 0.60 m or more than 1.2 m.16. Verandah
In residential buildings, the width of the verandah varies from 1.8 to 3 meters. In comparison, the width of the corridor varies from 0.8 to 1.2 meters. Also ReadStandard Sizes Of Rooms In Buildings
