How Many Houses Are in the World?

Based on a global average of four persons per family and a demographic growth factor of 7% applied to the world’s total population across all time. There are around 2.2 billion anticipated residences in the world as of the year 2021.

It depends on the number of people living there. And the square footage of the dwelling. More homes are constructed when there are fewer people living in each one.

How Many Houses Are in the World?

The concept of a ‘home’ is universal, yet the type, size, and luxury differ vastly from one corner of the world to another. Let’s journey through some interesting facts about homes around the world: which country boasts the most homes, the world’s largest and most expensive house, and the different types of houses that exist globally.

How Does the Global Population Differ from the Global Total of Households?

Our estimate of 2,300,000,000 homes is based on global census data collected over the past 20 years. We’ve factored in population growth since each estimate was made to arrive at our final tally. It’s consistent with population growth, and it depends on the average size of American households.

More homes can be built if families can live in them. As we will see in the following sections, the increasing number of homes is outpacing the rate of population growth because of the relatively new phenomenon of lower household sizes in western nations.

How Many More Houses in The World Are Needed to Build?

The world’s population is expected to double by the end of this century, from about 3.6 billion to about 7.2 billion. The United Nations predicts that by 2100, the world’s population would have risen to over 11.2 billion from its estimated 7.6 billion at the end of 2017. That’s what we call “medium growth,” by the way.

Seven times the current 511 million people who live in the countries of the European Union (before Brexit) would put the same strain on infrastructure and development, not to mention material resources.

As the world’s population continues to grow at a rate of 45 million per year, there will be a corresponding increase in demand for resources such as food, water, and materials, most importantly, shelter.

Which Country Has the Most Homes?

When it comes to the sheer number of households, China and India are the front runners. These two populous nations, with over a billion people each, naturally require a vast number of homes to accommodate their citizens.

With rapid urbanization and growth, both countries have seen a significant rise in the number of households over the past few decades.

Who Has the Biggest House on Earth?

The title of the largest house in the world goes to the Istana Nurul Iman Palace in Brunei. Serving as the official residence of the Sultan of Brunei, this opulent palace sprawls over a massive 2.15 million square feet.

Beyond its size, it boasts golden domes, a banquet hall that can host up to 5,000 guests, a mosque for 1,500 people, 5 swimming pools, and a 110-car garage, among other luxurious features.

Who Has the No. 1 Most Expensive House in the World?

When we shift our gaze from size to price, the Antilia in Mumbai, India stands tall. Owned by Mukesh Ambani, the chairman of Reliance Industries, this 27-story skyscraper residence is valued at over $2 billion.

While it’s located in one of the busiest cities in the world, Antilia offers every luxury imaginable, from three helipads to a 168-car garage, a grand ballroom, a theatre, a spa, and multiple swimming pools.

Which is the Cheapest House in the World?

While property prices have skyrocketed in many parts of the globe, there are still places where housing can be astonishingly affordable. In recent times, one of the most talked-about ‘cheap’ homes was a house in Zalesie, Poland, which was built for just $150.

The project, spearheaded by architect Renata Tubisz, utilized recycled materials and volunteer labor. It’s worth noting, however, that while the house’s construction cost was low, it does not factor in the price of the land or other potential externalities.

There are also initiatives in various parts of the world where houses are being built for low costs to address homelessness and provide affordable housing solutions.

What is the Smallest House in the World?

If size matters to you, then the title for the smallest house is bound to intrigue. The Smallest House in Great Britain, located in Conwy, Wales, has become somewhat of a tourist attraction.

Measuring 10 feet in height, 5.5 feet in width, and 10 feet in depth, it’s incredibly compact. A full-sized man can cover the width of the house with outstretched arms!

However, in the realm of modern, movable homes, the title might go to the ‘Tumbleweed Tiny House’ company’s EPU model, which measures a mere 89 square feet.

What is the Richest Palace in the World?

Moving from the world of the small and affordable to the realm of the vast and luxurious, we come to palaces – the epitome of opulence and grandeur.

The Istana Nurul Iman Palace in Brunei is not only the largest residential palace globally, but it’s also arguably the richest. It’s the official residence of the Sultan of Brunei.

With a staggering 2.15 million square feet of space, the palace includes golden domes, a mosque that can accommodate 1,500 people, 5 swimming pools, and air-conditioned stables for the Sultan’s polo ponies. Its estimated value is in the billions, making it one of the most valuable residences on earth.

How Many Types of Houses Are There in the World?

The diversity in housing styles across the globe is astonishing. Here are some prominent types of houses found worldwide:

  1. Bungalows: One-story houses, often with a broad front porch.
  2. Apartments: Multi-story buildings divided into separate dwellings.
  3. Villas: Larger houses, often in the countryside or coastal areas.
  4. Cottages: Small, typically old houses in the countryside.
  5. Townhouses: Multi-floor homes attached in a row.
  6. Igloos: Dome-shaped houses made of blocks of ice, often associated with the Inuit.
  7. Stilt Houses: Homes raised on piles over the surface of the soil or a body of water.
  8. Huts: Small, simple single-story houses.
  9. Yurts: Circular tents made of felt or fabric, associated with Central Asian nomads.
  10. Mansions: Large, opulent houses with many rooms and luxurious features.

Of course, this list just scratches the surface, as the architecture and type of houses vary widely based on culture, climate, and resources available.


As a result of the existing and projected need for new homes, governments are actively seeking to promote new developments in “offsite”. Prefabricated – construction methods to increase the rate at which new homes may be built.

For the future, offsite building has been given a lot of attention in the UK’s Industrial Strategy, which was published in November 2017. Over the past decade, this industry has expanded dramatically as new markets emerged in the healthcare, educational, and commercial construction sectors.

However, finding new approaches to the issue is necessary if prefab construction is to meet the demand for more homes at a faster rate. Thanks for read our Article How Many Houses Are in the World.
