4 storey house design Bedgram Gopalganj

House design Bedgram: Two units combined 2786 square feet

On the ground floor

We have made two units on the ground floor. Even after that, we have kept car parking. And we have kept a guard room. We have kept living space for the guard. There is a bathroom and a cooking area. 

Initially, there was one unit on the ground floor. Later, the client made two small units of two rooms. There is an approximately 12 ft pitched road in front of the client's land.

On the second floor

Since the client will live there themselves, five bedrooms have been made, four bathrooms have been made, and four verandas have been made; a reading room has been made; there is a large kitchen of course; and a very long drawing room.

 

Main bedroom: 12’-0” X 14’-0”

Study room: 12’-0” X 10’-0”

Toilet: 5’-0” X 10’-0”

Toilet: 5’-0” X 7’-0”

There are 6 verandas

Use Portland Composite Cement(PCC), of Strength=32.5Mpa. for brickwork, plaster, sunshade, lintel, false slab.

1. Water used for mixing of concrete shall be of portable standard (free of salt, silt, clay, loam, dust, organic materials, etc.).
2. Any type of admixture shall be used as per the approval & guidance of the Structural Engineer.

3D design When I started, I showed the work to the client step-by-step on their WhatsApp; some of their modifications are shared here with you.

 

Personally, we find it very beautiful to have surrounding trees; the client wanted [unclear] the trees [unclear] to look at them well.

3D design If done, a proper guideline is obtained on how a building will look. And if it is not done, the mason labour will think one way, and their thoughts will not match yours. You will not get what you want.

What must be done in construction work

38 x 78 ft three-room layout south-facing building has turned out very beautiful. The client liked it very much.
