Residential Building Plan

Residential Building Plan (3Bhk)

This is a residential building plan designed for a plot area of approximately 7000 square feet. The plan includes four flats of equal size, each being a 3BHK (3 bedrooms, hall, and kitchen). In each flat, there are three bedrooms, each with an attached bathroom and toilet. Additionally, 4 balconies are incorporated, with one directly connected to the drawing or living room.

The common areas in each flat comprise one kitchen, one dining area, and one living space. The building plan features outer walls with a thickness of 10 inches, providing structural strength, while the partition or inner walls have a thickness of 5 inches for internal division.

For vertical movement, the plan includes two staircases designed in a dogleg configuration and one elevator. All doors and windows are sized according to Indian Standards (IS).

On each floor, there are a total of 12 bedrooms and 12 bathrooms with attached toilets, distributed among the four flats. The common areas on each floor include a drawing area, dining area, kitchen, and a balcony.

It’s important to note that this description represents a conceptual design idea for a residential building plan, showcasing a thoughtful arrangement of living spaces and amenities for the occupants.

Residential Building Plan

What is a residential floor plan?

A residential floor plan is like a map that shows how a home is set up. It gives a top-down view, so you can see where rooms are, where walls, doors, and windows are, and other important parts of the house. It can also point out things like sinks and toilets in bathrooms and kitchens. However, it doesn’t usually show where furniture goes; that part is left for you to decide when you move in!

Understanding Residential Building Design

Designing homes is what residential building design is all about. It includes thinking up, planning, and building houses, whether they’re for one family or many. This type of designing, which is part of architecture, focuses on making homes that look nice and work well.

Important Parts of Residential Building Design


  • Designers think about things like how rooms are arranged, how much space there is, and how the outside of the house looks to make it visually appealing.


  • Planning means figuring out where everything goes inside the house. It considers what people need and want in their homes.


  • Building is the part where the actual construction happens. It’s when the design and plans become a real house, using materials and making sure everything follows safety rules.

Features of Residential Building Plan Design


  • Making homes that look good is a big part of residential design. Designers want houses to fit in with the area and be what people like.


  • Besides looking nice, homes also need to work well. This means they should be practical and comfortable to live in.

Space Use

  • Making the best use of space is crucial. Designers want to use every inch wisely while keeping the home feeling open.

Needs of People and Community

  • Designers think about what each person living in the house needs and also consider how the house fits into the neighborhood or community.

Eco-Friendly Practices

  • Nowadays, home design often includes being kind to the environment. This can mean using energy wisely, choosing eco-friendly materials, and building in ways that are good for the planet.

So, residential building design is a special part of architecture that focuses on making homes that not only look good but also work well for the people living in them. It’s a mix of thinking about the design, planning where everything goes, and building the actual house. All these things together aim to create homes that make people happy and comfortable.

How do you plan a residential building?

Planning a house involves a few important steps to make a good floor plan. Here’s how it works:

Pick a Spot

  • Start by choosing the area where you want to build or renovate a house. It could be an empty piece of land or a place that needs some fixing up.

Measure Things

  • If there’s already a building, measure the walls, doors, and furniture accurately. This is important to make sure the floor plan shows the real sizes of everything.

Draw the Walls

  • Draw the outer walls of the building to outline the space. This includes the outside walls that hold up the structure of the building.

Add Important Features

  • Put in important things like doors, windows, and other important parts of the building. These things not only make it look good but also affect how the building works.

Add Furniture

  • Place furniture on the floor plan to see how each room will look. Think about where beds, sofas, and tables should go. This helps understand how practical and comfortable the living spaces will be.

These steps give a basic way to plan a house. It’s important to think about how things look and how they work. Professionals like architects often use special computer programs to make detailed and accurate floor plans, including things like where the electrical and plumbing systems should go.
