ADU Collection
Accessory Dwelling Units (ADUs) offer versatile, space-efficient living solutions that maximize every square foot while maintaining the comfort of a traditional home. These secondary housing units, whether attached to the main house or standing independently, typically range from 400 to 1,200 square feet and feature thoughtful architectural elements that create the illusion of larger spaces.
Originally popular during the post-war housing boom as "granny flats" or "in-law suites," ADUs have evolved to meet modern housing needs, particularly in dense urban areas where housing costs continue to rise. Their design DNA draws from both craftsman cottages and minimalist modern architecture, creating spaces that feel both intimate and contemporary.
Most ADU floor plans emphasize open-concept living areas, with kitchen, dining, and living spaces flowing together seamlessly. Clever storage solutions, such as built-in cabinets and multi-functional furniture spaces, are hallmarks of well-designed ADUs. Many plans feature 1-2 bedrooms, a full bathroom, and ceiling heights of at least 9 feet to enhance spatial perception.
Today's ADU designs incorporate energy-efficient features like ample natural lighting, superior insulation, and smart home technology. Popular amenities include compact appliances, murphy beds, outdoor living connections through French doors or sliding glass panels, and flexible spaces that can transition from home office to guest room as needed.
Whether serving as a rental property, multi-generational housing solution, or private guest quarters, ADUs offer significant advantages for homeowners. They can provide passive income, increase property value, and create independent living spaces while maintaining privacy. Their smaller footprint also means reduced maintenance costs and energy consumption compared to traditional homes.
These small-footprint homes particularly appeal to homeowners seeking to age in place, young professionals working remotely, or families looking to accommodate adult children or aging parents. With their efficient use of space, ADUs represent a practical solution for sustainable urban density without sacrificing comfort or style.

More Information
All of our floor plans are designed in-house and come with various options to make your dream home custom to you.

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.
