Quick Answer
The cheapest type of house to build is usually a simple rectangular home with a compact footprint.
A simple rectangular house with a basic roofline, standard windows, stacked plumbing, and practical finishes is usually the most affordable type of home to build. A two-story version can lower the cost per square foot even more because it reduces foundation and roof area.
The biggest mistake is choosing a plan based only on square footage. The shape, roofline, foundation, lot conditions, permits, site work, and contractor bid details can all change the final cost.
Cheapest Types of Houses to Build Compared
Use this comparison as a planning starting point. Your final cost depends on your state, city, lot, foundation, finish level, labor market, and contractor scope.
| House Type | Cost Level | Why It Can Be Cheaper | Best For | Next Step |
|---|---|---|---|---|
| Simple rectangular house | Lowest | A simple box shape reduces framing, roofing, foundation complexity, exterior corners, and labor time. | Budget builds, starter homes, rural lots, simple family homes | Browse simple house plans → |
| Two-story house | Very efficient | A two-story home can place more living space over a smaller foundation and roof footprint. | Narrow lots, higher land cost areas, families needing more bedrooms | Estimate total build cost → |
| Small ranch house | Moderate to low | Ranch homes are simple to build, but a single-story layout needs more foundation and roof area than a two-story home. | Aging-in-place, easy access, simple layouts, wide lots | Compare plan options → |
| Prefab or modular home | Can be low | Factory-built sections can reduce on-site labor and speed up construction, but delivery, crane access, foundation, and finish work still matter. | Faster builds, controlled designs, areas with good modular availability | Get cost report → |
| Barndominium | Market-dependent | A simple metal shell can be efficient, especially in rural areas, but insulation, interior finish, utilities, and code requirements can raise the final cost. | Rural land, workshops, garage-heavy layouts, open floor plans | Analyze contractor bid → |
| Tiny house | Low total, high per sq ft | The total project can be cheaper because the home is small, but kitchens, bathrooms, utilities, and permits make the cost per square foot higher. | Minimal living, guest units, vacation lots, ADU-style projects | Check ADU options → |

Browse practical plans, then estimate your full build cost based on location, square footage, foundation, and finish level.
What Makes a House Cheaper to Build?
The cheapest homes are not always the smallest. A very small custom home can have a high cost per square foot if it still needs a full kitchen, bathroom, utility connections, permits, foundation, and mechanical systems. The real savings usually come from simplicity.
Rectangular plans usually cost less than homes with many corners, bump-outs, wings, or complex exterior shapes.
Gable and simple hip roofs are usually cheaper than steep, multi-gable, dormer-heavy, or custom roof designs.
A compact two-story footprint can reduce foundation and roof cost compared with the same square footage spread across one level.
Keeping kitchens, bathrooms, laundry, and mechanical spaces close together can reduce plumbing and mechanical costs.
Standard-size windows and doors are usually cheaper than oversized glass, custom shapes, large sliders, or specialty units.
Cabinets, flooring, tile, fixtures, exterior siding, and trim choices can move a budget from affordable to expensive quickly.
Is a Two-Story House Cheaper Than a Ranch?
A two-story house can be cheaper per square foot than a ranch because the same living area can sit on a smaller foundation and roof. For example, a 2,000 sq ft one-story home may need a 2,000 sq ft foundation footprint, while a 2,000 sq ft two-story home may only need roughly half that footprint.
That does not mean two-story is always better. Ranch homes can be easier to live in, easier to access, and popular for buyers who want single-level living. But if the goal is pure construction efficiency, a compact two-story plan often has an advantage.
Plan cost depends on footprint
Foundation, roofing, exterior walls, and site work can change the final number more than many buyers expect.
Compare One vs Two Story →Thinking about prefab?
Prefab can save time, but delivery, crane access, foundation, utility work, permits, and finish scope still need to be priced.
Compare Prefab vs Custom →Are Prefab or Modular Homes the Cheapest?
Prefab and modular homes can reduce labor time because major sections are built in a factory. This can help control schedule and reduce waste. But the final cost is not just the factory package.
You still need land, foundation, utility connections, driveway, crane access, permits, inspections, finish work, and sometimes local modifications. In some markets prefab is cheaper; in others it is similar to stick-built construction.
What to Avoid if You Want the Cheapest Build
Many homes become expensive because of design complexity, not just size. If your goal is a lower build cost, avoid these common budget traps.
Overly complex rooflines with multiple peaks, valleys, dormers, or steep pitches
Large single-story footprints when a two-story layout would work
Too many exterior corners, bump-outs, angled walls, and custom shapes
Oversized windows, custom doors, large glass walls, and expensive exterior systems
Plans that do not fit your lot width, setbacks, driveway access, or septic layout
Low contractor bids with vague allowances, exclusions, or missing site work
Best Next Step Based on Your Situation
Different buyers need different tools. If you are still comparing home styles, start with plans. If you are close to choosing a lot or builder, check cost, permits, and bid details before signing.

Frequently Asked Questions
What is the cheapest type of house to build in 2026?
The cheapest type of house to build is usually a simple rectangular home with a basic roofline, compact footprint, standard windows, and practical finishes. A two-story version can be even more cost-efficient because it reduces foundation and roof area per square foot of living space.
Is a ranch house cheaper to build than a two-story house?
A ranch house can be simpler to build, but it is not always cheaper. A one-story home usually needs more foundation and roof area for the same square footage. A two-story home can often reduce foundation and roofing costs because the footprint is smaller.
Are prefab homes cheaper than stick-built homes?
Prefab or modular homes can be cheaper in some markets because factory-built components reduce on-site labor and timeline. However, the final cost still depends on foundation, delivery, crane access, utility connections, permits, site work, and interior finish level.
Are barndominiums the cheapest type of house?
Barndominiums can be affordable in some rural markets, especially when the design is simple. But they are not always the cheapest once insulation, interior finish, plumbing, HVAC, electrical, permits, and code requirements are included.
What house shape is cheapest to build?
A rectangle is usually the cheapest house shape to build. Simple rectangular plans reduce exterior wall length, framing complexity, roof complexity, foundation corners, and labor time.
Should I buy house plans before estimating build cost?
It is better to estimate build cost before buying or finalizing house plans. A plan that looks affordable online may become expensive if it has a complex roof, oversized footprint, difficult foundation, custom windows, or does not fit your lot.
