Estimated cost
$285,000 – $315,000+
Ranges cover design, engineering, the permit process, and construction under one roof, for standard Orange County site conditions. City permit, plan-check and inspection fees are paid by the owner to the city and are not in these ranges, and neither are finish materials, landscaping or solar. Sloped lots, long utility runs, panel upgrades, and coastal or fire overlays can move the number. It is an educational estimate, not a quote or a promise.
A smart two-bedroom layout designed for privacy, comfort, and flexible living
When it comes to building an ADU, the floor plan you choose makes all the difference. A well-designed layout can transform a compact space into a comfortable, functional home that works for different lifestyles.
One standout option for homeowners in Orange County is the Bellecielo ADU plan , a thoughtfully designed 830 square foot layout that balances privacy, openness, and versatility.
A Layout Designed for Real Living
The Bellecielo floor plan features two bedrooms and two bathrooms , making it ideal for shared living while still maintaining personal space.
What sets this layout apart is its symmetrical design . Each bedroom is placed on opposite ends of the unit, with its own adjacent bathroom. This creates a natural separation that allows occupants to enjoy privacy without sacrificing comfort.
At the center of the home is an open-concept kitchen and living area , which connects both sides of the unit and creates a welcoming, shared space.
Key Features of the Bellecielo ADU
- 830 square feet of well-utilized space
- 2 bedrooms positioned for maximum privacy
- 2 full bathrooms for convenience and independence
- Open kitchen layout that connects to the living area
- Balanced design ideal for shared living situations
Every part of this layout is designed to make daily living easier and more efficient.
Why This Floor Plan Works
The Bellecielo layout is not just about space. It is about how that space is used.
By separating the bedrooms and centralizing the common area, the design supports both independent living and shared interaction . This makes it especially valuable for households where privacy is important.
The open living and kitchen area also helps the unit feel larger and more connected, which is essential in ADU design.
IDEAL USE CASES FOR BELLECIELO
This floor plan is highly flexible and works well for a variety of needs:
MULTI-GENERATIONAL LIVING
Perfect for families who want to keep loved ones close while still giving everyone their own space.
LONG-TERM RENTAL INCOME
Two bedrooms and two bathrooms make this layout attractive to tenants, increasing rental value and occupancy potential.
HOME OFFICE AND GUEST SUITE
One bedroom can easily function as a dedicated workspace while the other serves as a guest room.
AGING-IN-PLACE FOR PARENTS
The private bedroom and bathroom setup provides comfort, independence, and accessibility for older family members.
A Floor Plan That Adapts to Your Lifestyle
One of the biggest advantages of the Bellecielo ADU is its flexibility. It is not limited to one purpose.
What starts as a family space can later transition into a rental unit or a hybrid living and work environment. This adaptability makes it a smart long-term investment for homeowners.
Planning Your ADU the Right Way
Choosing the right floor plan is one of the most important decisions in your ADU project. It affects not only how the space looks, but how it functions every day.
Before moving forward, it is important to consider your goals, budget, and how you plan to use the space over time.
Why Bellecielo is a Smart Choice
The Bellecielo ADU floor plan is a strong example of how thoughtful design can maximize both comfort and functionality within a compact footprint.
With its balanced layout, private bedroom placement, and open shared spaces, it offers a practical solution for homeowners looking to create flexible living environments.
Whether you are building for family, rental income, or a combination of both, a well-designed floor plan like Bellecielo can make all the difference.
