Shelter and Houses

Class 4 | CBSE / NCERT / ICSE

🎯 Learning Objectives

📖 Let Us Begin!

A house is a shelter that protects us from heat, cold, rain, wind, and wild animals. Every person needs a house to live safely and comfortably.

India is a large country with many different climates -- hot deserts, heavy rainfall areas, cold mountains, and flood-prone plains. That is why houses in different parts of India look very different from each other!

Types of Houses

Type of HouseDescriptionWhere Found
Kutcha HouseMade of mud, straw, bamboo, or thatch; not very strongVillages across India
Pucca HouseMade of bricks, cement, concrete, and steel; strong and lastingCities and towns
TentMade of cloth or animal skin; easy to carry and set upRajasthan (nomads), army camps
HouseboatA boat that is used as a home; floats on waterDal Lake, Srinagar (Kashmir)
Stilt HouseBuilt on raised poles above the ground to stay safe from floodsAssam, Meghalaya, coastal areas
IglooA dome-shaped house made of blocks of hard snowArctic regions (not India, but studied for comparison)
Flat / ApartmentA home in a multi-storey building; many families live in one buildingBig cities like Mumbai, Delhi, Bengaluru

Materials Used for Building Houses

Example
Common Building Materials

Kutcha houses: Mud, clay, bamboo, straw, palm leaves, wood.

Pucca houses: Bricks, cement, sand, concrete, steel rods, glass, tiles.

Special houses: Houseboats use wood; tents use cloth or canvas; igloos use snow blocks.

How Climate Affects House Design

Region / ClimateHouse FeatureReason
Rajasthan (hot desert)Thick walls, small windows, flat roofsThick walls keep the inside cool; small windows block hot wind and sand
Kerala (heavy rain)Sloping roofs with tilesRainwater slides off easily and does not collect on the roof
Kashmir (heavy snow)Sloping roofs, wooden housesSnow slides off sloping roofs; wood keeps the house warm
Assam (floods)Stilt houses (raised on poles)Raised floors keep the house above flood water
Big citiesMulti-storey apartmentsLess land is available, so buildings go upward
The climate and geography of a place decide what kind of house people build there.

How Houses Have Changed Over Time

Long ago, early humans lived in caves to protect themselves from wild animals and bad weather. Slowly, they learned to build huts using mud, leaves, and branches. Over time, people discovered bricks, cement, and steel, and began building stronger houses.

Today, we have tall buildings with many floors, lifts, running water, and electricity. Houses have changed from simple mud huts to modern apartments with all comforts.

Example
Example: Changes Over Time

Caves (earliest) --> Mud huts --> Brick houses --> Multi-storey buildings --> Smart homes (today).
