One Story House Plans – Functional, Elegant, and Timeless Designs
Designing a one story house plan is one of the most versatile and practical ways to create a home that is both comfortable and efficient. Unlike multi-level homes, single story home designs prioritize convenience, accessibility, and flow — making them ideal for families, retirees, and homeowners who value seamless indoor–outdoor living.
At Ataman Studio, we specialize in creating custom one story house plans in California, blending modern design with timeless layouts that fit local zoning codes, lifestyle needs, and environmental conditions. Whether you’re envisioning a ranch-style estate, a contemporary single-level home, or a compact yet luxurious retreat, we guide you through every stage — from concept to construction.
Why Choose a One Story Home Design?
Single story houses have been a staple of California living for decades, and for good reason. They offer unique benefits that make them stand out compared to multi-story residences:
- Accessibility: No stairs make single level homes perfect for aging-in-place and multigenerational families.
- Indoor–Outdoor Flow: Large sliding doors, patios, and courtyards connect seamlessly with California’s climate.
- Energy Efficiency: Heating and cooling are often simpler and more cost-effective in a one story house.
- Open Layout Potential: A one level floor plan allows for expansive great rooms, vaulted ceilings, and flexible space configurations.
- Safety: Families with children or elderly residents often prefer single story homes for ease of mobility and reduced fall risk.
For many homeowners, a one story house plan feels more grounded, intimate, and connected to the landscape than taller multi-level designs.
Popular One Story House Styles
At Ataman Studio, we design homes that reflect both modern trends and California’s architectural heritage. Some of the most popular one story home styles include:
- Ranch Style Homes – Sprawling layouts with open floor plans, large windows, and easy backyard access.
- Modern Contemporary – Minimalist designs with flat roofs, clean lines, and indoor–outdoor integration.
- Mediterranean & Spanish Revival – Stucco exteriors, arched windows, and tiled courtyards inspired by California tradition.
- Craftsman Bungalows – Cozy yet refined homes with natural materials, exposed beams, and large porches.
- Luxury Estate Ranches – High-end single story homes designed for larger lots, offering private wings, guest quarters, and resort-style outdoor spaces.
Each plan can be tailored to suit your lifestyle, lot conditions, and personal taste.
Layout Options for One Story Floor Plans
When it comes to one level floor plans, flexibility is the greatest advantage. A well-designed single story home can accommodate both compact urban lots and sprawling suburban estates. Some layout options include:
- Open Concept Living: Combining kitchen, dining, and living spaces into one great room.
- Split Bedroom Layout: Master suite on one side, children’s or guest bedrooms on the other for privacy.
- Indoor–Outdoor Courtyard Designs: Centered around patios or landscaped courtyards.
- Extended Wings: Creating dedicated areas for guests, home offices, or rental suites.
- Luxury Additions: Chef’s kitchens, spa bathrooms, home gyms, or entertainment rooms — all without stairs.
We also integrate smart home systems, energy-efficient HVAC, and natural daylighting strategies into our single story plans.
California-Specific Considerations
Designing a one story house in California requires balancing creativity with compliance. Our team ensures that every plan meets the following key requirements:
- Zoning & Setbacks: Adhering to local lot coverage, property line, and height restrictions.
- Energy Codes (Title 24): Ensuring homes meet California’s strict sustainability standards.
- Seismic Safety: Engineering for earthquake resistance.
- Hillside & Coastal Lots: Addressing slope stabilization, retaining walls, wind loads, and salt air exposure.
By addressing these challenges during the design phase, we help avoid costly revisions later.
Cost of Building a One Story Home
The cost of constructing a single story home varies depending on size, design complexity, and finishes. On average in California:
- Construction Costs: $250–$500+ per sq ft.
- Permitting & Fees: Can range from $20,000 to $60,000 depending on the city.
- Luxury Features: Pools, outdoor kitchens, and premium finishes can significantly increase costs.
While one story homes may require a larger footprint than a two-story equivalent, they often save on stair construction and structural complexity.

FAQ: One Story House Plans
Are one-story houses cheaper to build than two-story houses?
Not always. While you save on stairs and second-story framing, one-story homes require a larger foundation and roof area, which can increase material costs. The difference often comes down to lot size, desired square footage, and finishes.
What is the ideal size for a one-story house?
Single-story homes can range from 1,200 sq ft for compact homes to 4,500+ sq ft for luxury ranch-style estates. The right size depends on your family needs, lot coverage limits, and budget.
Are one-story homes more energy efficient?
Yes, in many cases. Heating and cooling are easier since all rooms are on the same level, and air circulation is more consistent. We also incorporate passive solar strategies and Title 24 energy compliance to lower long-term utility bills.
Can a one-story home include vaulted ceilings?
Absolutely. One of the main advantages of a single-level design is the ability to create dramatic vaulted ceilings or exposed beams without worrying about a second floor. This enhances natural light and creates an open, airy atmosphere.
Do one-story homes work on small lots?
Yes, but layout efficiency becomes critical. For narrow or irregular lots, we design U-shaped or L-shaped floor plans to maximize privacy and create usable outdoor courtyards. For very tight sites, we may recommend compact footprints or partial basements.
What’s the timeline for designing and building a one-story house?
Typically, design and permitting take 4–6 months, and construction ranges from 8–12 months depending on square footage, complexity, and contractor availability.
Can I add an ADU to a one-story home?
Yes — many homeowners pair a one-story home with a detached or attached ADU to create extra rental income or guest space. We can integrate ADU planning into the initial design to avoid future rework.
