Shelter — Houses Across Regions of HP and India

Overview

Shelter is a fundamental human need, ranking alongside food and clothing. For the HP TET Environmental Studies paper, this topic tests your understanding of how geography, climate, available materials, and cultural practices shape the houses people build. Questions typically ask you to match house types with regions, identify building materials, or explain why certain designs suit specific climates.

Himachal Pradesh offers a unique study area because its terrain ranges from sub-tropical foothills to cold desert zones like Spiti. This diversity means HP alone showcases multiple housing styles — from the slate-roofed Kath-Kuni architecture of Kullu to the flat-roofed mud houses of Lahaul-Spiti. Understanding the logic behind these variations is more valuable than rote memorization.

The EVS curriculum treats shelter not just as geography but as an integrated concept linking environment, livelihood, family structure, and local resources. Expect pedagogy-linked questions on how to teach this topic using local examples and activity-based learning.

Key Concepts

• **Climate determines design**: Hot regions need thick walls and high ceilings for cooling; cold regions need thick walls for insulation and small windows to retain heat; rainy regions need sloped roofs for water drainage.

• **Locally available materials**: Houses traditionally use what is nearby — bamboo and thatch in Assam, mud and stone in Rajasthan, wood and slate in Himachal, ice blocks for igloos in polar regions.

• **Kath-Kuni architecture**: The signature HP style uses alternating layers of wood (kath) and stone (kuni) without mortar, providing earthquake resistance and thermal insulation. Found in Kullu, Shimla, and Kinnaur.

• **Flat roofs vs sloped roofs**: Flat roofs suit dry regions (Spiti, Rajasthan) where rain is scarce and roofs double as drying/storage areas. Sloped roofs suit heavy rainfall or snowfall areas.

• **Stilt houses**: Elevated houses protect against floods, wild animals, and humidity. Common in Assam, Meghalaya, and coastal areas.

• **Nomadic and temporary shelters**: Tents (rebo) of Gaddi shepherds in HP, houseboats in Kashmir, and caravans of Rajasthani Banjaras reflect mobile lifestyles.

• **Urbanization changes housing**: Modern houses use cement, bricks, and steel regardless of climate, leading to loss of traditional knowledge and sometimes unsuitable designs.
