How to Understand the Average Cost to Build a 4 Bedroom House

Building your own house is a major undertaking and there are many decisions to be made before you can break ground. Time needs to be spent considering floor plans and interior finishes and deciding on the square footage of your new home. A popular size for a single-family home in 2022 is a four-bedroom house, which allows you to have a master bedroom, rooms for two children, and a guest bedroom for family and friends to come to stay. We look at the logistics and the average cost of building a 4-bed house as well as some other popular house sizes.

What size house do I need?

When moving out of your existing home and building your own home many people want to size up, moving into a large house with more bedrooms, while others are looking to downsize from their existing house. We help you decide what house size, and how many bedrooms you might need.

How many bedrooms per square foot of house?

In the US at present, the average bedroom size is 132 square feet and the average master bedroom is about 225 square feet. While there are no hard and fast rules about the number of bedrooms in a specific sized house there are some rough guides to how many bedrooms you might find in certain home sizes.

  • 2 bedroom houses are generally around 1,000 square feet and usually, only have one bathroom but they can be as small as 500 square feet (tiny house!) and as big as 5,000 square feet.
  • 3 bedroom houses are usually around 2,000 square feet but can range from 1,000 - 2,600 square feet, and usually have two bathrooms
  • 4 bedroom houses on average range from 1,900- 2,400 square feet and have 2-3 bathrooms. They can be as large as 3,500 or bigger, and as small as 1,200 square feet.
  • 5 bedroom houses are often around 2,500 - 3,000 square feet, although they can be as small as 2,000 square feet and as large as 10,000 square feet. They typically have 4 bathrooms.

Recommended house sizes

While bigger might seem better getting the right size house for your family is about more than just having the right amount of square foot per person. A larger house will cost more to build and maintain, and in some parts of the country, land costs make very large houses prohibitively expensive. But it's also important not to build your house too small, or you'll need to move again quickly. Here are some tips for getting the right house size.

Square feet per person

According to the Financial Samurai, the ideal amount of square footage per person living in a house is 600-700, although in a more densely populated area 400-600 might be more realistic.

Location or size

Sometimes compromises need to be made with the size of a house. For example, getting into the right school district might be more important than the huge yard and extra living area in your new home. While you might get more space for your money living out in the suburbs but your commute, gym, and friends might all be a long drive away, so having a smaller home closer to work might be worthwhile.


Perhaps you think you need a 5 bedroom house because you have a large family who might want to come and visit. But in reality, are they all going to visit at the same time? Will one or two guest bedrooms be more than enough? You don't want to be paying for 3 guest bedrooms that are only fully occupied for a couple of days each year.

Future needs

Unless you want to move house again in a few years it's important to look at your life stage and what your future needs might be. Are you likely to have an expanding family with more children, or elderly parents coming to visit, or are your children getting ready to leave home, making a more compact home seem more appealing?

The average cost to build a house

When you see average house construction costs online these figures often include only the labor and materials costs and don't include things like the cost of land, which can be very cheap in some states and rural locations or very expensive in other states and in more urban or suburban areas. You also have to include professional fees, of architects and general contractors in your total house building costs.

Home building cost breakdown

Here we look at the overall cost of building a new construction home and what is involved in the home construction costs. Here is a rough breakdown, excluding the cost of land:

  • Professional fees, design & permits - 10-25%
  • Labor - 30-60%
  • Materials - 30-50%


On average expect to pay between $3,000 and $150,000 for a suitable plot of land, depending on where you are building and the state of the land. Unfinished lots will be at the lower end of the price range and developed lots in modern housing developments will usually cost from $50,000 - $100,000.

If you purchase an unfinished lot you need to do surveys and connect your land to the power, water, and sewers for your area. This averages about $3,000 - $40,000 depending on how far you are from the utilities. You will also have to clear and level the land, which may involve excavators and other heavy machinery, depending on what is currently on the land (existing structures, trees, etc).

Professional fees

Once you have your land you need to get floor plans and blueprints for your new home drawn up, or purchase ready drawn plans online. The average prices for plans range from $2,000 - $8,000, but if you want to build a high-end custom home you may end up paying a lot more for an architect to draw up your plans.

While not a major cost building permits are an essential one and you can expect to spend up to around $2,000 on obtaining them.

Unless you are an experienced construction expert you'll want to hire a general contractor custom home builders to manage the entire home building process for you.

While they may seem like a large expense at 10-20% of the total build cost (materials and labor), they are an invaluable resource, making sure your dream home building process runs smoothly, doesn't have any major delays, and stays on budget.

Material costs

The cost of building materials can vary a lot depending on the style of build and interior and exterior finishes you choose, but on average, material costs make up around 30-50% of the total building costs.

When choosing materials, especially for interior finishes or exterior finishes it's possible to save quite a lot of money by choosing cheaper options, many of which can be upgraded at a later date.

It's not usually a good idea though, to try and save money on the main foundation, structure, and major systems as they will ideally last for the lifetime of your house.

Here are some rough costs of some of the main materials you'll need when you build a house.

  • Concrete for foundations, or structure: $1,000 - $10,000 total
  • Lumber for framing and carpentry: $25,000 - $65,000 total
  • Roofing materials: $1,000 - $3,000 total
  • Insulation: $0.10 - $1 per square foot
  • Drywall for the interior: $10 per sheet
  • Flooring materials: $1 - $5 per square foot
  • Siding for the exterior: $2 - $15 per square foot

Labor costs

Labor costs are a very large proportion of the total cost to build a house, making up 30-60% of the total construction costs (materials and labor).

Your labor costs will probably include:

  • Carpenters
  • Roofers
  • Concrete workers
  • Electricians
  • Plumbers
  • HVAC installers
  • Painters
  • Framers

You may also choose to hire a landscaper and interior designer to make your dream home look as beautiful as possible.
