How many pillars/ column required for 400 sq ft house | how many pillars do i need to build a 400 sq ft house construction | number of pillars needed for 20×20 feet plot

A RCC or reinforced concrete column is a compressive structural member of concrete that designed to carry compressive loads, composed of concreting material (mixture of Portland cement, sand, aggregate or stone with water) with an embedded steel of different diameter such as 12mm, 16mm, 20mm and so — frame to provide reinforcement.

Pillars/ rcc column and beams give strength to a building to withstand all the loading condition and adversities of the climate over the years and stand tall for several decades together. But if the pillars and beams are placed in the wrong place, they can create adverse effects on the occupants of the house.

A wrongly built pillar or column may considerably hamper the growth of your family members both in the short and the long run and also may create disputes amongst the family members. Thus, Vastu for pillars has to be necessarily followed for a favorable outcome.

**When we go through the column design we should mention following point:** 1) the possible distance or span and depth it all depend on load to which the beam is subjected, 2) column size depend on amount of load on the column acting on it by beam and RCC slab, 3) many axial and Lateral load acting on column, 4) large span greatly influence the bending moment not only on beam, but it also affect the column due to stress acting on it, 5) Thumb Rule for column design are appropriate for very small project like G+1,G+2 & G+3 Building and 6) column design for building construction it depend on many factors like topography, whether and size of building.

Others factors also influence the total number of pillars required for 400 sq ft house construction are ground load bearing condition, purpose of the building, occupation density, height and levels of the building, specific neighbourhood & location where built, climatic & other geographical conditions, expected life of the building and duration of use, facade & other architectural design factors & requirements, materials for structural works, external & partition walls if any and materials for finishing and interior. Plumbing & electrical requirements if any.

**How many pillars/ column required for 400 sq ft house:-** there are approximately 8 to 9 nos of pillars are required for 400 sq ft house construction or for your one storey (G+0), two storey (G+1), three storey (G+2) building. 400 sqft of house may be of size 20’x20’, provide pillars/ rcc column at 10 feet span centre to center so parallel to 20 feet side you will have 3 pillars and for two sides, it is 3×2=6 no’s of pillars, for 20 feet side, you will have one extra on each side, totalling two nos, therefore you will have totally 6+2= 8 no’s of pillars or column. Thus you will need approx 8 nos pillars to build 400 sq ft house.
