Rules for House Map Design

Designing your own house is always full of amazing experiences when you try to convert your imaginations and fantasy of your dream house into peace of reality. I also have amazing experiences when I first design my house using free available tools in internet. I will take you to my journey of experience here .

Choosing Plot Size and Surrounding

Plot is the peace of land where some one decide to built home. The shape of plot and surrounding is very important to overall appearance of house. most preferable shape of plot is rectangular with various ratios as applicable to the plot size . Normally width / length ratio ranging from 0.5 to 0.7 best for house construction.

Corner plot facing road or park is always preferred for better view and ventilations, However any plot with sufficient size can be designed to have proper ventilations , natural light and beautiful appearance through proper set of rules of House design. Here I will discuss some of those important set of rules of house design which any designer’s should keep in mind while doing any house design project.

Setback

Setback can be explained as the minimum open space required around any building or structure. Municipal regulations provide that a specific distance should be maintained between a building and the boundary of the plot on which the building is being constructed. This distance is necessary to ensure so that the structure stays away from roads, water bodies or other buildings. Setbacks are required at the front, rear and sides of buildings and the specifications vary from one area to another.

What is the importance of a setback?

• To ensure all buildings receive adequate natural light to ensure sufficient ventilation.
• To protect entities such as water bodies located close to a building from being adversely affected by the construction and human inhabitation.
• To protect one building from the shadow of another, which would otherwise obstruct adequate provision of ventilations and sunlight.
• To protect buildings from noise-causing elements, such as nearby industries, airports or highways.
• To ensure easy access to the buildings for emergency services such as fire engine during mishap.
• To ensure one building does not infringe on another building’s right to sunlight, ventilation, greenery and vehicular access.

The Municipality or regularized Authority provide set of rules for setbacks based on various plot size and location of residential society.

Example U.P. Housing and Development Board Regulations for Building byelaws latest Amendment 2016 Provide following rules for setback for residential buildings.
