First of all, the design of the manual itself is the important thing when you are developing a guidance, for example, this is a zone A, this is how the coding is worked so now, it says UPA 01, UP is Uttar Pradesh, A is what is the zone and within the zone, you might have 2, 3 typologies, so that is where the typology number. So, for example when you say, the state name and then zone; 1, 2, 3, 4, 5, like that.
Detailed Explanation
This chunk explains the coding system used for house typologies in different zones. Each code consists of a state abbreviation (like UP for Uttar Pradesh) followed by the zone letter, and finally a typology number which indicates specific styles or characteristics of houses within that zone.
Examples & Analogies
Think of the coding system as similar to identifying food items at a restaurant. The menu might have codes where the first letter represents the type of cuisine, the second letter indicates the main ingredient, and the numbers tell you the specific dish. This helps customers quickly find what they want!

So, this is how it has been organized and how one can read this document. For example, you take the Assam state where you have the zone A is here and the zone B okay and the zone C which is towards the Bangladesh and the Manipur side of it and you have the zone D and zone E, so this is how and they are all classified by vulnerability to natural hazards, physiographic and access to building materials and the cultural compatibility.
Detailed Explanation
In this part, the text discusses how different zones in Assam are categorized based on their vulnerability to natural disasters, the geography of the area, the availability of construction materials, and cultural factors. This classification helps in understanding the specific needs for building in each zone.
Examples & Analogies
Imagine you are planning a camping trip. You would choose different locations based on factors like weather (vulnerability), nearby ponds (access to resources), and the kinds of activities you enjoy (cultural compatibility). Each factor helps determine the best camping spot!
