In construction, a site plan is a blueprint of a proposed development work. It is a crucial drawing used by architects, engineers, and urban planners at the planning stage. It shows the entire extent of the proposed site and includes the minutest details such as type of soil and habitation. All future developments on a proposed site are made keeping in view these characteristics as indicated in the site plan. In a nutshell, site plan drawings are integral to all sorts of developments in all kinds of constructions.
What is a site plan?
A site plan is a diagram showing the proposed developments on a site. In other words, a site plan is a graphic representation of how a proposed building would develop with other integral parts like parking and landscaping. Site plans are made after multiple examinations of the site and discussions about the site’s characteristics.

Site plan scale
Land is a vast area. Drawing it on a paper is difficult. Here, the site plan scale comes into the picture. Also referred as block plan, a site plan scale is a measure used to imagine the actual vastness of the proposed site. Depending on the size of the proposed site, a site plan scale may vary from 1:200 to 1:500. This means, when printed on paper, the site map would be 200 or 500 times smaller than the actual area. For smaller projects, larger site plan scales can be used. Similarly, for very large site plans, a much smaller site plan scale can be used.
Site plan architecture
Planners should be aware of the government rules such as building byelaws and local development laws, to draft site plans. All site plans need to be compliant with building bye laws of the specific area.
