A Shelter So High – Class 5 EVS Chapter 13 (NCERT)

What is 'A Shelter So High' About?

This chapter describes a special kind of house found in flood-prone areas of India, such as parts of Assam, where rivers overflow every year during the monsoon. To keep the house safe from floodwater, snakes, and even wandering elephants, people build their homes on tall wooden poles called stilts, several feet above the ground. The floor of the house becomes like a raised platform, and a ladder or steps are used to climb up.

The chapter also shares the story of a family that built their house extra high after elephants damaged their earlier, shorter house while passing through the area at night. This shows us that shelter design is a lesson learned from experience with local conditions — floods, wild animals, heavy rain, or extreme cold — and it keeps changing to solve real problems faced by the people living there.

Why Do Houses Look Different in Different Places?

A shelter's job is to protect people from weather and danger, so its shape and material depend on the surroundings. In hot, dry deserts (like Rajasthan), houses have thick mud walls and small windows to keep out heat and sand. In cold mountain regions (like Ladakh), houses have flat roofs, small windows, and thick stone or mud walls to trap warmth. In heavy rainfall or flood areas (like Assam, Kerala backwaters), houses are raised on stilts or built as houseboats so water can pass underneath without entering. Coastal areas often use sloping roofs made of coconut leaves so rainwater drains quickly. This proves an important EVS idea: local climate, land, and available material decide the design of a shelter, not just people's choice.

How a Stilt House Protects a Family (Step by Step)

1. Step 1: Choose strong wooden poles — Thick, sturdy tree trunks or bamboo poles are selected because they must hold up the entire house and survive years of flooding water pushing against them.
2. Step 2: Fix poles deep into the ground — The poles are driven deep into the earth so they do not tilt or fall even when the soil below becomes soft and muddy during floods.
3. Step 3: Build a raised platform — A wooden or bamboo floor is built on top of the poles, several feet above the highest flood level recorded in that area, keeping the living space dry.
4. Step 4: Add walls and a sloping roof — Walls of bamboo, wood, or mud-plastered reed are added, with a sloping thatched or tin roof so rain slides off quickly instead of collecting.
5. Step 5: Add a ladder or staircase — A removable or fixed ladder connects the ground to the raised floor; during floods people can even pull the ladder up for extra safety.
6. Step 6: Keep space underneath free — The area below the house is left open so floodwater and even animals like elephants can pass through without damaging the living area above.

Worked Examples: Matching Shelter to Region

• Example 1 — Question: Why do people in Assam build houses on stilts? Explanation: Assam receives very heavy rainfall and the Brahmaputra river floods almost every year. Wild elephants also pass through villages at night. Building the house high above the ground on strong poles keeps the floor, belongings, and family safe from both floodwater and animals. Answer: Stilt houses are built to protect people from yearly floods and from wild animals like elephants.
• Example 2 — Question: A student says 'People in Rajasthan should also build stilt houses.' Is this correct? Explanation: Rajasthan is a hot desert region with very little rainfall and no flooding problem, so raising a house on stilts is not needed there. Instead, thick mud walls and small windows help keep the inside cool. Answer: No, stilt houses are not needed in Rajasthan; thick-walled houses suit the desert climate better.
• Example 3 — Question: How does the sloping roof of a stilt house help the family? Explanation: A sloping roof does not allow rainwater to collect on top; instead, water slides off quickly, preventing leakage and weight damage during the heavy rainy season. Answer: The sloping roof lets rainwater drain off fast, keeping the house dry and strong during monsoon.

Comparing Two Types of Houses

Important Terms from the Chapter

Shelter

Any structure that protects people or animals from weather, danger, or wild animals; a house is one type of shelter.

Stilts

Tall, strong wooden or bamboo poles used to raise a house above the ground, keeping it safe from floodwater and animals.

Flood-prone area

A region where rivers or heavy rain regularly cause water to rise and flood the land, such as parts of Assam near the Brahmaputra.

Thatched roof

A roof made from dried plant material like straw, reeds, or palm leaves, often built with a slope to drain rainwater quickly.

Adaptation (in shelter design)

Changing the design of a house to suit local weather, land, and dangers, such as raising it high in flood areas.

Common Mistakes and Exam Tips

Many students confuse 'stilts' with just 'poles used for decoration' — remember stilts are structural supports that lift the entire house above ground level for safety, not for style. Another common mistake is thinking all Indian houses look the same; always mention that climate, land, and locally available material decide house design, and give a specific regional example (Assam stilt house, Rajasthan mud house, Ladakh flat-roof house) to score full marks. In answers, always connect the reason (flood/heat/cold) to the feature (stilts/thick walls/small windows) — examiners award marks for this cause-and-effect link, not just naming the feature alone.

Practice Questions with Solutions

• Q: Why was the house in the chapter built higher than before? A: Step 1: Recall that the family's earlier house was damaged by wild elephants passing through at night. Step 2: The area also suffers from yearly flooding during heavy rains. Step 3: To protect the house from both dangers, the family rebuilt it on taller stilts, well above the reach of floodwater and animals. Final answer: The house was built higher to protect the family from wild elephants and floodwater, after their earlier, shorter house was damaged.
• Q: Name two materials commonly used to build a stilt house and explain why each is chosen. A: Step 1: Identify materials mentioned in the chapter — bamboo/wood for poles and floor, and thatch or tin for the roof. Step 2: Bamboo and wood are chosen because they are strong, lightweight, locally available, and can bear the weight of the house on stilts. Step 3: Thatch or tin is chosen for the roof because it allows rainwater to slide off quickly due to its sloping shape. Final answer: Bamboo/wood is used for strong stilts and flooring, while thatch or tin is used for a sloping roof that drains rainwater fast.
• Q: How would a house in a cold mountain region like Ladakh differ from a stilt house in Assam? Give two differences. A: Step 1: Consider the climate of each region — Ladakh is cold and dry, Assam is hot and flood-prone. Step 2: In Ladakh, houses have thick mud or stone walls and small windows to trap heat and keep out cold winds. Step 3: In Assam, houses are raised on stilts with open space underneath to let floodwater pass and keep the living area dry. Final answer: Ladakh houses have thick walls and small windows to stay warm, while Assam's stilt houses are raised above the ground to avoid floods; their designs solve completely different problems.
• Q: A friend says, 'All houses in India should be built on stilts because it looks strong.' Do you agree? Give a reason. A: Step 1: Recall that house design depends on local climate and dangers, not on appearance. Step 2: Stilt houses are useful mainly in flood-prone or animal-prone areas; in dry or non-flooding regions, stilts are unnecessary and expensive. Step 3: Building unsuitable houses wastes material and does not solve any real local problem. Final answer: No, I do not agree; stilt houses are needed only in flood-prone or animal-prone regions, and other areas should use house designs suited to their own climate and land.
• Q: List three dangers that shelters in different parts of India are designed to protect people from, with one example each. A: Step 1: Think of three different regions and their main problems. Step 2: Floods and wild animals — Assam's stilt houses solve this. Step 3: Extreme heat — Rajasthan's thick-walled mud houses solve this. Step 4: Extreme cold — Ladakh's flat-roofed stone houses solve this. Final answer: Shelters protect against floods/animals (Assam stilt houses), heat (Rajasthan mud houses), and cold (Ladakh stone houses).
