What Is the Cheapest Type of House to Build? Alternative Homes and Building Materials

The cheapest type of house to build is a rectangular tiny home — though your location, materials, and more can impact costs. $287,466 is the average cost of new home construction in the U.S.

No matter how small your home is, building in a city with a high cost of living means land and taxes will cost more than in affordable areas like Arkansas. A complex home design or costly materials like lumber and limestone increase your building expenses.

Making an offer on a pre-existing home is typically more affordable than building a home. New construction may be more affordable if you find a great deal on land or build in a competitive market. Otherwise, customization and few up-front renovation costs are the best benefits to building your own home. 

Cheapest Type of House to Build:
  1. Tiny Home
  2. Container Home
  3. Cob Home
  4. Colonial Home
  5. Ranch Home
  6. Prefabricated Home

1. Tiny Homes

When you're buying your first home, would you consider living in a house that measures 400 square feet or less? Because that would mean you're living in a tiny home. Tiny homes are no bigger than a two-car garage. That's tiny.

Tiny homes have grown in popularity over the last decade as an affordable and sustainable house style. Tiny houses are less than 400 square feet and are typically square or rectangular in shape. The simple design and small space reduce the materials needed, keeping construction affordable. 

Tiny homes can be bought and are often built since they’re not very common. It can be difficult to secure a mortgage for alternative homes like these depending on how rare they are in your area, so be prepared to purchase with cash. 

Average cost to build: $97,500

Average cost to buy: $45,400

2. Shipping Container Homes

When you're buying your first home and you want to keep your options open for shipping yourself overseas, give a look at shipping container homes. They're actual shipping containers. And you live in them.

Shipping container homes are built around the structure of a retired shipping container so you save time and money on framing. Shipping containers can be used for tiny homes, or combined with other containers for the construction of a larger house. 

Shipping containers generally come in two sizes — 20 feet by 8 feet (160 square feet), or 40 feet by 8 feet (320 square feet).

Container homes are only legal in select states, including:

  • Alaska
  • California
  • Colorado
  • Florida
  • Georgia
  • Louisiana
  • Minnesota
  • Missouri
  • New York
  • North Carolina
  • Oregon
  • Pennsylvania
  • Tennessee
  • Texas
  • Washington, D.C. 

Like tiny homes, it may be difficult to get a mortgage for container homes. Research your local area and save up some cash if you plan to build one. 

Average cost to build: $16,500-$44,500

Average cost to buy: $32,000-$61,000 

3. Cob Construction Homes

Would you live in a cob home as a first-time home buyer? It's like that Rick & Morty episode where everything on a certain planet is on a cob, down to the atomic level. The air is breathable air and the planet looks like Earth except everything is on a cob. Forget Morty and Summer not minding the cob planet. Rick's against it.

Cob is a clay mixture that has been used around the world for centuries. Cob can form the walls and foundation of a home. Homeowners usually build their own cob houses, so prepare for manual labor. Cob homes are not common and aren’t readily available to buy in the U.S. 

Cob construction is sturdy, sustainable, and small with a unique look. Cob can be combined with other construction practices or materials to create a modern home, or used for smaller projects like sheds and garden walls.

Cob homes are not typical in most areas and may be difficult to secure a mortgage for, much like tiny homes and shipping container homes. Most home buyers finance their purchase and are more interested in the next three home types.

Average cost to build: $7,000

Cost to buy: $499,900

4. Colonial Homes

Colonial homes aren't cob homes. They're colonial homes. And the Rick & Morty writers never wrote a joke about Colonial homes.

Colonial homes are common around the East Coast and are symmetrical, rectangular-shaped houses. Their simple design is more affordable to build than complex or asymmetrical houses. 

Colonial homes have evolved over time and modern styles are often used for mansions. It can be hard to find affordable colonial homes ready to buy, so if you plan on building, sticking to a simple layout and small size keeps construction affordable. They’re also easy to find plans for and can be built up rather than out, so you can save on foundation costs. 

Average cost to build: $300 per square foot 

Cost to buy: $172,961

5. Ranch Homes

Ranch homes are popular with fIrst-time home buyers and other people that don't care whether their homes has stairs in it. Ranch is also better on buffalo wings than blue cheese is, and I will die on that hill.

Ranch homes are the most popular home style in the U.S. They’re another rectangular-shaped house, though they come in “T” or “L” shapes, too. A home with a simple and concise layout is the cheapest type of house to build. 

Ranch homes are typically single-story structures with attached garages. They’re easy to find construction plans for and highly customizable, so you can find a home that fits your needs and budget. If you choose to purchase a ranch home, they come in a variety of sizes and shapes for options that fit any budget. 

Average cost to build: $150 per square foot

Cost to buy: $159,900

6. Prefabricated Homes

If you've ever driven on the highway behind an actual house, you've driven behind a pre-fabricated home. Wide Load indeed.

Prefabricated homes are built off-site, transported to your property, and assembled on-site. You choose from your builder’s selection of layouts and materials to customize the home. Building the home in panels off-site and restricting the build options makes prefabricated or modular homes affordable. 

The home layout and upgrades are customizable, but these changes are costly. Prefabricated homes aren’t cheap — just cheaper than an on-site build, so keep affordable style in mind. Prefabricated homes are quicker to construct than on-site builds and are generally more sustainable.

Average cost to build: $90-$120 per square foot 

Average cost to buy: $100-$200 per square foot

Cheapest Materials to Build a House

Your house style and size determine the amount of materials you need to buy, which is the core of a home’s expense. There are plenty of cheap building materials and alternatives to consider to cut costs.

1. Prefabricated panel

Prefabricated panels are built off-site and shipped to you, ready for assembly. You or your contractor can order prefabricated wall panels, framing, floor joists, and roof trusses based on your preferred house style and layout, or layouts offered by the prefabrication company. 

Prefabricated panels can be made of wood, steel, or concrete. You can also opt to add finishes, paint, or features like fireproofing depending on your panel supplier’s services. 

2. Concrete sheets

Concrete sheets are a specific type of prefabricated panel. They’re just as easy to install and save time and money from labor costs, on-site framing and pouring, and help to avoid weather delays. Concrete is an affordable option that’s secure, fireproof, insulating, and weatherproof. 

3. Shipping containers

Retired shipping containers are an affordable and sustainable option for setting the base structure of your home. A single container is great for tiny home living. You can also assemble multiple containers or build off of a single container for a larger space. 

4. Reclaimed wood

Reclaimed wood is more affordable than fresh lumber and keeps wood out of landfills. You may find it for free through online Buy Nothing groups or construction sites — just be sure to ask permission to pick up discarded wood.

Using reclaimed wood as paneling or anywhere it's visible gives your home a unique look with a mix of grains and colors. You can also refinish reclaimed wood to match your aesthetic. 

5. Bamboo

Bamboo is a durable lumber alternative that grows quicker than trees, so it’s sustainable. It’s versatile and can be used for framing, roofing, flooring, and fencing. Some bamboo species are also considered lucky plants for your home. 

There’s a variety of bamboo species, and the time of harvest impacts its durability. Research the bamboo that fits your construction needs and providers before you buy. 

6. Brick

Brick is an affordable building material that can be bought new, recycled from old construction, or even made at home. You can find salvaged brick through online marketplaces, Buy Nothing groups, and construction or demolition sites.

Brick installation is time-consuming, so you may pay more in labor. If you’re willing and experienced enough to lay your own brick or know a good contractor, this can still be an affordable option for your house. 

7. Cob

Cob is a mixture of clay, sand, straw, and water that you can make at home. It can be formed around a simple frame, built up on its own, or made into bricks for construction. It’s a good insulator and a sturdy building material that has been used for centuries. 

Cob may not fit your lifestyle needs and is best for tiny homes. You can use it in addition to other construction methods or to build a shed or landscaping structures. Check local laws if you plan to build a cob home to ensure it’s permitted in your city and state. 

8. Recycled bottles

Recycled bottles can be used as a construction alternative that’s popular for sustainability or aesthetics. Ecobricks are plastic bottles stuffed with plastic waste to create durable bricks that reduce pollution. They can technically be used to build a house, but they’re better suited for small structures like gardens, sheds, or even furniture. 

Glass bottles can also be trimmed to remove the neck and secured in adobe, cob, or concrete. You can place the cut ends of the bottles together and leave the bottom ends uncovered for a stained glass effect. 

Cheapest Way to Build a House

If you have the experience and know-how, then constructing your own home is the cheapest way to build a house. Follow pre-created design plans or work with an architect to ensure your home layout works. Also consider hiring subcontractors for electrical, plumbing, or other areas where you lack experience. It’s cheaper to do it right the first time than to pay to fix mistakes later. 

If you decide to hire a home builder, spend the extra money to hire an experienced contractor. An experienced builder also serves as a consultant to give you design and savings tips. They’ll also be able to spot potential problems early on so you can avoid the cost of mistakes made by inexperience. 

The more you prepare up-front, the better your building experience will be. Create an accurate budget, get all necessary permits early, and ensure your construction plans are feasible and within your budget.

Is it cheaper to build or buy a house?

It’s typically cheaper to buy an existing home than to build a new one. Location and personal preferences have an impact, too. HomeAdvisor reports the average cost to buy a home is $285,000, while building a home averages $287,466 and can cost up to $150,000 more than buying. 

If you live in a competitive market, it may make more sense to build a home than compete with other buyers. New construction may also be a better option if you have a lot of specific needs for your home that would require expensive renovations in an existing house. 

Can you build a small house for $50K?

Technically yes, you can build a house for $50,000, but it won’t be easy. A simple tiny house or repurposed shipping container makes building a home for under $50,000 achievable. However, you need land to build on to begin construction, which can be much more expensive. You also need to pay for all building permits, which can cost up to $3,000

What is the most expensive part of building a house?

High lumber costs make framing the most expensive part of home construction. Your actual property is also costly and varies significantly by location. Land may be more expensive than the entire home construction in high-cost areas. 

Buying a home is more convenient

Buying a pre-existing home is quicker than building a new house, especially if you consider weather delays, construction complications, or the potential to go over budget. You can also tour an existing home to find the right look and feel. 

New construction is based on your design, so it’s highly customizable. The finished product and quality vary — your finished house may be everything you dreamed of, or it might need some improvements. 

New construction is easier to customize

New construction allows you to collaborate with an architect to design your dream home and customize everything from kitchen cabinets to closet space. You have the option to renovate a pre-existing home, but a house’s structure may limit your creativity. New construction is ideal if you have specific ideas about what you want in your house. 

Building a new home can be an affordable option in high-competition housing markets. It can seem expensive at first, but alternative homes and building materials help keep you within your budget. It’s often more sustainable and allows you to personalize your home. Research to decide if buying or building is right for you, and learn more about first-time home buyer payment options

New technology also makes new home construction smarter than ever. Check out these innovations that can cut the cost of construction and add modern features to your home.
