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.

Key Facts

| Region/State | House Type | Key Materials | Climate Adaptation | |--------------|------------|---------------|-------------------| | Kullu, Kinnaur, Shimla (HP) | Kath-Kuni | Wood, stone, slate | Earthquake-resistant, warm in winter | | Lahaul-Spiti (HP) | Flat-roofed mud houses | Mud, stone, timber | Retains heat, roof used for drying | | Rajasthan | Haveli / mud houses | Mud, limestone, thatch | Thick walls keep interior cool | | Assam, Meghalaya | Stilt houses (Chang Ghar) | Bamboo, wood, thatch | Protection from floods and humidity | | Kerala | Nalukettu / tiled houses | Laterite, wood, clay tiles | Sloped roofs for heavy monsoon | | Kashmir | Wooden houses with Hamam | Deodar wood, mud | Hamam (under-floor heating) for winters | | Goa, Coastal Karnataka | Houses with verandas | Laterite, clay tiles | Ventilation and rain protection | | Thar Desert | Bhunga (circular huts) | Mud, cow dung, thatch | Circular shape resists sandstorms | | Ladakh | Flat-roofed stone houses | Stone, mud, poplar wood | Thick walls for insulation, flat roof for scarce rain |

**Five must-remember facts:**

1. Kath-Kuni literally means "wood-stone" and uses no cement — joints are interlocked. 2. Sloped roofs in HP often use slate (locally called "pathhar") from quarries in Kangra and Mandi. 3. Gaddi tribe of HP uses portable tents called "rebo" during seasonal migration with sheep. 4. Houseboats (Shikaras and Dungas) in Dal Lake, Kashmir, are floating homes and tourist attractions. 5. Igloos are made by Inuit people using compacted snow blocks — snow traps air, providing insulation.

Worked Examples

**Example 1**: Why do houses in Lahaul-Spiti have flat roofs while houses in Kullu have sloped roofs?

*Solution*:

• Lahaul-Spiti lies in a rain-shadow zone with very low annual rainfall (under 500 mm). Flat roofs are practical because:
• No need to drain heavy water
• Roof serves as open space for drying apricots, barley, and fodder
• Easier to construct with available mud and stone
• Kullu receives heavy monsoon rainfall and snowfall. Sloped roofs:
• Allow rain and snow to slide off, preventing accumulation
• Slate tiles are waterproof and locally available
• Prevent structural damage from water seepage

**Example 2**: Match the following:

| House Type | Region | |------------|--------| | A. Bhunga | 1. Assam | | B. Chang Ghar | 2. Gujarat (Kutch) | | C. Nalukettu | 3. Kerala |

*Solution*: A-2, B-1, C-3

• Bhunga: Circular mud huts in Kutch, Gujarat — resist desert winds
• Chang Ghar: Stilt houses in Assam — protection from floods
• Nalukettu: Traditional Kerala house with central courtyard — ventilation in humid climate

**Example 3**: A teacher wants to teach "Shelter" using activity-based learning. Suggest one activity.

*Solution*: The teacher can ask students to collect pictures or draw houses from their own village and a different region. In class, students compare materials used, roof shapes, and climate of both areas. This connects local knowledge with broader concepts and follows the EVS principle of "learning from the immediate environment."

Common Mistakes

• **Confusing Kath-Kuni with log cabins**: Kath-Kuni uses alternating horizontal layers of wood and stone, not stacked logs. The stone layers are crucial for thermal mass.

• **Assuming all HP houses are the same**: HP has diverse climatic zones. Spiti houses differ completely from Kangra houses. Always specify the district/region.

• **Ignoring the "why" behind design**: Students memorize house names but forget the climate-material logic. Exams often ask reasoning questions, not just identification.

• **Thinking modern = better**: EVS perspective values traditional architecture for sustainability. Cement houses in cold HP regions often perform worse thermally than Kath-Kuni.

• **Mixing up stilt house regions**: Stilt houses exist in Northeast India (floods) and also in some coastal areas. Don't assume stilts only mean Assam.

Quick Reference

• **Kath-Kuni** = Wood + Stone, no cement, earthquake-resistant — Kullu, Kinnaur, Shimla
• **Flat roof** = Dry climate, low rain — Spiti, Rajasthan, Ladakh
• **Sloped roof** = Heavy rain/snow — Kullu, Kerala, Assam
• **Stilt houses** = Flood-prone areas — Assam, Meghalaya, coastal regions
• **Bhunga** = Circular mud hut — Kutch, Gujarat
• **Climate + Materials + Culture = House Design** — the core EVS formula for shelter
