Single Story House Plans vs Two Story House Plans: Which Is Right for You?
Choosing between a one-story and two-story home is not simply a style decision. The number of floors affects how bedrooms are arranged, how your household moves through the home, how much land the house may occupy, and how private or connected different living areas feel.
When comparing single story house plans with two-story designs, start with your daily routines and the property where you plan to build. A one-story layout may make everyday movement simpler, while a two-story plan may organize more living space vertically and create greater separation between different parts of the home.
SWLA Constructors & Development offers a variety of house plans for homeowners building across Southwest Louisiana and parts of Southeast Texas.
Quick Answer: Is a One-Story or Two-Story House Better?
Neither is automatically better.
A single-story home may be a strong fit if you prefer everyday living without stairs, want bedrooms and common areas on one level, or have enough property for the desired footprint.
A two-story home may work better when you want to organize more living space vertically, separate bedrooms from common areas, or use the homesite differently.
The best choice depends on your household, floor plan, property, and long-term priorities.
What Is the Main Difference Between Single Story House Plans and Two Story House Plans?
The most obvious difference is vertical space, but that affects much more than where the stairs go.
In a single-story home, bedrooms, bathrooms, the kitchen, living areas, laundry, and other primary spaces are generally located on the same floor. This can create convenient movement through the home but may require a wider overall footprint as square footage increases.
A two-story house divides at least part of the living area between levels. This can create greater separation between sleeping and gathering areas while allowing more living space to be arranged within a potentially more compact ground-level footprint.
Neither configuration guarantees better functionality. The layout still matters.
Why Do Homeowners Choose Single Story House Plans?
Single-story living appeals to many buyers because the main household functions stay on one level.
That can be useful for families with young children, homeowners who prefer fewer stairs, people thinking about future mobility, or anyone who simply likes having bedrooms, kitchens, laundry, and living areas more directly connected.
Everyday Movement Can Be Simpler
Without a second level, you do not need to move between floors for bedrooms, laundry, or other frequently used spaces when the plan keeps those functions together.
That can make daily routines feel straightforward.
It can also make moving furniture, carrying laundry, or reaching different parts of the home easier for some households.
Single-Story Living May Support Long-Term Accessibility Goals
Homeowners planning to stay in a house for many years sometimes prefer having the primary living areas on one floor.
That does not automatically make every single-story plan accessible. Door widths, bathroom layouts, entries, steps, flooring transitions, and other design details can still matter.
If accessibility is an important goal, discuss those needs specifically during the design process rather than assuming that one floor alone solves them.
Indoor and Outdoor Areas Can Feel Closely Connected
A one-story floor plan may provide multiple opportunities to connect bedrooms or common living areas to porches, patios, or the yard, depending on the design.
For homeowners who value outdoor living, this can be an important part of the plan comparison.
The property should still be considered because outdoor areas, driveway access, drainage, and other site needs compete for space around the building footprint.
What Are the Trade-Offs of a Single-Story Home?
One-story living can be convenient, but it is not automatically the right choice for every property or household.
The Building Footprint May Be Wider
As the amount of living space increases, placing everything on one floor can require more ground-level area.
That may matter when considering:
Lot dimensions
Setbacks
Driveway placement
Drainage
Septic needs where applicable
Outdoor living
Garage placement
Existing trees or site features
Other property-specific requirements
A larger property does not necessarily mean every one-story footprint will fit exactly where you want it.
The proposed house should be reviewed with the homesite before major site decisions are made.
Privacy Depends Heavily on Room Placement
When everything is located on one level, bedroom placement becomes especially important.
A plan may place the primary suite on one side of the home and secondary bedrooms on the other, while another may group the sleeping areas together.
Look at the actual floor plan rather than assuming all one-story homes provide the same level of privacy.
Why Do Buyers Consider Two Story House Plans?
Two-story homes use vertical space to organize the floor plan.
That can help separate different household activities and may provide another way to fit the desired living space onto a property.
More Separation Between Living and Sleeping Areas
A two-story design can place common spaces downstairs while locating some or all bedrooms upstairs.
For households that entertain frequently, have older children, or simply prefer more separation between active and quiet areas, that arrangement may be appealing.
Other two-story plans may keep the primary bedroom downstairs while placing secondary bedrooms upstairs.
That can provide a different balance between convenience and privacy.
Two-Story Plans Can Organize Space Differently on the Property
Because some living area is stacked vertically, a two-story design may achieve the desired square footage without placing all of it at ground level.
This does not mean every two-story home automatically has a small footprint. Garages, porches, first-floor rooms, roof design, and other features still affect the total project.
However, vertical planning can give homeowners another option when comparing how the home may work on a particular homesite.
Stairs Should Be a Real Part of the Decision
Do not choose a two-story home based only on exterior appearance or bedroom count.
Think about how often your household will use the stairs.
Consider:
Young children
Older family members
Guests
Carrying laundry
Moving furniture
Daily trips between bedrooms and common areas
Long-term mobility preferences
Stairs are not inherently a problem, but they become part of everyday life in a two-story home.
If you expect to stay in the house for many years, consider whether that arrangement still makes sense for your future household.
Which Layout Offers More Privacy?
Either can, depending on the floor plan.
A two-story house can create natural separation by placing bedrooms upstairs and common areas downstairs. That may be useful for families who want quieter sleeping areas.
A single-story plan can also provide strong privacy when it uses a split-bedroom arrangement that separates the primary suite from secondary bedrooms.
Instead of assuming one floor configuration is more private, compare:
Primary-suite placement
Secondary-bedroom placement
Guest rooms
Bathrooms
Living-room location
Kitchen activity
Home office
Garage entry
Outdoor gathering areas
Privacy comes from thoughtful layout decisions, not simply the number of stories.
Which Is Better for Families With Children?
The answer depends partly on the age of the children and how the family wants bedrooms arranged.
Parents with very young children may prefer bedrooms on the same floor. Families with older children or teenagers may appreciate more separation.
Consider nighttime routines, supervision preferences, noise, bathrooms, play areas, and whether the layout may still work as children grow.
There is no universal family floor plan.
The best design is the one that supports the household you actually have.
What About a First-Floor Primary Bedroom?
A first-floor primary suite can change the decision considerably.
Some two-story plans place the primary bedroom downstairs while keeping secondary bedrooms or flex spaces upstairs.
This gives homeowners access to the primary bedroom without relying on the stairs for everyday sleeping while still creating a separate upper level for other members of the household.
If long-term convenience is important but you also like the benefits of a two-story layout, this type of configuration may be worth considering.
Think About Laundry Placement
Laundry can become an important practical difference between plans.
If all bedrooms are upstairs but the laundry room is downstairs, clothes and linens may travel between floors regularly. A two-story plan with laundry near the bedrooms may create a different routine.
In a one-story home, laundry placement can still affect convenience. Look at its relationship to bedrooms, closets, mudrooms, and garage entries.
Small workflow details can have a bigger impact on daily life than features that initially look more impressive on a floor plan.
Compare Storage, Not Just Square Footage
A larger home can still feel short on storage if space is not allocated effectively.
Compare:
Bedroom closets
Linen storage
Pantry space
Laundry storage
Garage storage
Entry storage
Under-stair space where applicable
Flex rooms
Attic or other storage areas where part of the specific design
Do not assume two stories automatically provide more usable storage.
Look at the plan itself.
How Does the Property Affect the Decision?
Your homesite should be part of the one-story versus two-story conversation.
A particular property may influence:
Building orientation
Overall footprint
Driveway approach
Garage orientation
Drainage
Utilities
Septic placement where applicable
Setbacks
Outdoor areas
Construction access
Existing natural features
If you already own property, review the proposed floor plan before clearing or grading the land.
SWLA's Build on Your Land process is designed to consider the home and homesite together.

Are Single Story House Plans Better for Larger Lots?
Not necessarily.
A large lot may provide more flexibility for a wider footprint, but lot size alone does not determine whether a plan works.
The usable building area may still be affected by property dimensions, access, drainage, utilities, setbacks, wastewater requirements, easements, or other site conditions.
Likewise, some homeowners with large acreage may intentionally choose a two-story plan because they prefer its room arrangement or exterior design.
Choose based on the entire project, not one property characteristic.
Are Two Story House Plans Better for Narrower Properties?
Sometimes a vertically organized plan may provide more living area without placing every room at ground level, but this should not be treated as a universal rule.
The actual width and depth of the house still matter.
Garages, porches, setbacks, driveway access, utilities, and other property requirements can influence whether a specific plan fits.
Review the dimensions and footprint of the individual plan rather than assuming that every two-story house works on a narrower property.
Which Option Is More Energy Efficient?
Avoid assuming that either a one-story or two-story configuration is automatically more energy efficient.
Energy performance can depend on many factors, including:
Building design
Insulation
Windows and doors
HVAC design
Air sealing
Orientation
Construction details
Equipment
Climate
Occupant use
The number of floors is only one design characteristic.
If energy performance is a priority, discuss the specific building systems and design choices planned for the home rather than relying on a broad claim about one-story versus two-story construction.
Which Costs More to Build?
There is no reliable universal answer based only on the number of floors.
Two plans with similar living square footage may still differ in:
Foundation area
Roof structure
Stairs
Total under-roof square footage
Garage size
Porches
Design complexity
Site requirements
Interior selections
Structural requirements
Other project details
A one-story home should not automatically be described as cheaper or more expensive than a two-story home without comparing the actual plans and project scope.

Single Story House Plans for Southwest Louisiana
Single-story plans are common choices for homeowners who want bedrooms and everyday living areas on one level.
For buyers building in Southwest Louisiana, the right plan should still be considered alongside the individual property.
Land in Sulphur, Lake Charles, and surrounding areas can vary in size, drainage conditions, utility access, and other site characteristics.
SWLA Constructors offers a range of one-story designs through its House Plan Library, with different bedroom counts, layouts, garages, porches, and architectural styles.
Two Story House Plans for Louisiana Families
Two-story homes can be useful for households that want greater separation between floors or prefer a vertically organized layout.
Some families may like having secondary bedrooms upstairs. Others may prefer a first-floor primary suite with additional rooms above.
The best configuration depends on household routines, privacy preferences, future plans, property fit, and the specific design.
Browse actual floor plans rather than making the decision based solely on exterior appearance.
One-Story vs Two-Story Homes in Southeast Texas
Homeowners building in Southeast Texas face the same core decision: how should the floor plan support the household and property?
Properties around Brookeland, Sam Rayburn, and other parts of SWLA's Southeast Texas service area can vary significantly.
Whether you choose one or two floors, consider access, outdoor living, garage placement, utilities, drainage, wastewater needs where applicable, and how the house will sit on the specific property.
Buyers planning a Texas build can also explore Texas Homes.
Can You Customize the Floor Plan?
If an existing design is close to what you need, customization may be worth discussing before moving to a completely different plan.
SWLA's custom-home process allows homeowners to explore available house plans and discuss modifications based on their needs and project.
Possible discussions may include:
Bedroom arrangement
Flex space
Storage
Garage configuration
Porch areas
Interior layout
Other project-specific changes
The feasibility and effect of a modification depend on the specific plan and project.

A Simple Way to Compare One-Story and Two-Story Plans
Before deciding, compare the options using the same questions.
1. How Many Bedrooms Do You Need?
Think about current family members, guests, home offices, and realistic future needs.
2. Where Should the Bedrooms Be?
Decide whether you prefer everyone on one level or greater separation between rooms.
3. How Do You Feel About Stairs?
Consider your household today and your long-term plans.
4. What Spaces Do You Use Most?
Kitchen, laundry, living areas, home office, outdoor areas, and storage should be easy to use in daily life.
5. What Does Your Property Allow?
Review the actual building footprint with your land rather than choosing a plan in isolation.
6. How Much Privacy Do You Want?
Look at room placement and circulation, not simply the floor count.
7. Does One Plan Need Significant Changes?
A design that already fits your needs may be a stronger starting point than one that requires extensive modification.
Frequently Asked Questions
Are single story house plans better for families?
They can be a good fit for families that prefer bedrooms and shared living areas on the same floor. The right choice depends on bedroom placement, household routines, privacy needs, property fit, and long-term preferences.
Are two story house plans good for larger families?
They can be. Two-story plans may provide additional ways to separate bedrooms, common areas, offices, or flex spaces. Bedroom count and layout matter more than the number of floors alone.
Is a one-story home easier to live in?
Some homeowners find one-level living more convenient because everyday rooms can be reached without stairs. Whether it is better for you depends on your household and preferred layout.
Does a two-story house have a smaller footprint?
It can, because some living space is arranged vertically, but this is not guaranteed. The actual footprint depends on the individual plan, garage, porches, first-floor layout, and other design elements.
Is a one-story house cheaper to build than a two-story house?
Not necessarily. Construction cost depends on the actual plan, total under-roof area, foundation, roof design, site conditions, finishes, property requirements, and other project factors.
Which is better if I plan to stay in the home long term?
Some homeowners prefer one-story living when thinking about future mobility, while others choose two-story homes with a primary suite downstairs. Long-term needs should be considered as part of the specific floor plan.
Can SWLA customize a one-story or two-story house plan?
SWLA offers customizable house plans and works with homeowners through its Design-Build process. The changes appropriate for a particular home depend on the plan, property, and project scope.
Can I build either type of house on my own land?
SWLA builds on customer-owned property within its service area. The specific house plan should still be reviewed with the homesite because footprint, access, drainage, utilities, wastewater needs, setbacks, and other requirements can affect the project.
Compare the Floor Plan, Not Just the Number of Floors
One-story versus two-story is an important decision, but it should not be made in isolation.
Think about where you want bedrooms, how often you want to use stairs, how your family gathers, where laundry and storage belong, how much privacy you need, and how the home will fit your land.
Then compare actual floor plans based on those priorities.
