Casita Collection
Discover our collection of Casita floor plans, featuring compact yet luxurious living spaces that combine southwestern charm with modern functionality. These adaptable guest house and accessory dwelling unit (ADU) designs typically range from 400 to 800 square feet, making them perfect for multi-generational living, rental income, or creating a private retreat.
Traditional Casita layouts center around an open-concept great room that seamlessly connects the living and dining areas. Most plans feature a well-appointed kitchenette or full kitchen, a spacious bedroom, and a full bathroom with modern fixtures. Signature architectural elements include thick walls, exposed wooden beams (vigas), and covered porches (portales) that create natural shade and outdoor living space.
Today's Casita designs incorporate contemporary amenities while preserving their distinctive southwestern character. Energy-efficient windows, smart storage solutions, and flexible spaces that can serve as home offices or hobby rooms adapt these classic plans for modern living. Many layouts include built-in nooks, window seats, and interior details that maximize every square foot.
Whether attached to the main house or positioned as a standalone structure, Casitas offer privacy and independence while maintaining a connection to the primary residence. Their versatile nature makes them ideal for aging parents, adult children, or generating rental income through short-term stays. High ceilings, abundant natural light, and indoor-outdoor flow create spaces that feel significantly larger than their efficient footprint suggests.
These thoughtfully designed guest houses blend southwestern architectural traditions with practical features like dedicated parking, separate utility connections, and private entrances. Popular options include adding covered patios, small courtyards, or container gardens to extend the living space outdoors while maintaining the intimate scale that makes Casitas so appealing.

Exterior Wall Construction Choices
Most of our stock plans come as 2x4 exterior wall construction by default. We do provide options to change the exterior wall type. Those options include 2x6 exterior walls, Post Frame Construction, CMU Block Construction, etc.
Foundation Types
When de signing our house plans, a default foundation is set for a given plan. If possible, we include options to change the foundation type to better match your construction needs. For instance, if the default foundation is an unfinished basement, you'll have the option to change the foundation type to a walkout foundation, crawlspace, or slab foundation.
Please note: Some of our plans are designed with special foundation needs, such as post and pier for waterfront properties. These plans may not allow an option to choose another foundation type. If you find yourself in need of an alternate foundation and aren't given the choice, please fill out the alteration request on the plan page.
Right Reading Reverse
One of our more popular options is reversing the plan. Ordering the reverse option will not only flip the plan on the sets for you, it will also correct the text to make the plan read correctly while reversed.
CAD Files
All of our plans are offered as digital PDF downloads. If you want to make changes to the plan yourself, there is an add-on option that will give you the CAD files. Our CAD files are exported in AutoCAD format. You must have software capable of opening CAD files to use them. This option is great if you are in the business of home building and need to make slight changes to the plans per lot.
Cost to Build Report
All of our house plans come with a 100% free cost-to-build report. Just find the orange section on the plan page, type in your zip code, and choose your finish quality level. Note that this tool is for estimation purposes only and should not be used in any other way.
