A Large Functional Layout with Room to Expand

The Franklin is designed to keep the main living space efficient while giving you options to expand. The first floor handles the majority of daily use, with an open kitchen, dining, and living area at the center of the home. The primary suite is separated from the secondary bedroom for privacy, while a dedicated office adds flexibility for work or an additional sleeping space.

A large mudroom and laundry area connect directly to the garage, creating a practical entry point for daily use. Storage is built in throughout the plan, including a pantry, closets, and mechanical space, so the home functions well without relying on excess square footage.

Upstairs, the layout adds a third bedroom, a full bath, and a loft that overlooks the main living area. This creates additional living space without increasing the home’s footprint.

The bonus room over the garage is intentionally separated from the main house. It can be finished as a media room, guest space, or left unfinished for storage. This gives you the ability to control costs upfront while keeping expansion options available as your needs change.

Barndominium Living Area

The main living space is laid out in a straight, functional flow with the kitchen, dining, and living areas connected without wasted space. The kitchen includes a large working footprint with direct access to the pantry and dining area. The living room is centered around a fireplace and opens to the back porch, creating a natural connection to outdoor space.

This layout keeps everything within reach while still feeling open. It works for daily living, small gatherings, and larger groups without needing additional square footage.

Private Master Suite with Practical Layout

The primary suite is positioned away from the main living area and secondary bedroom to create separation and privacy. The bedroom has enough space for full furniture layout without crowding.

The master bath includes dual vanities, a walk-in shower, and direct access to a large walk-in closet. The closet connects efficiently within the suite, keeping everything contained and easy to use without extra hallway space.

Bonus Room Over Garage for Flexible Use

The bonus room sits above the garage and is separated from the main house, making it usable without impacting the primary living space. At over 900 square feet, it can be finished as a media room, guest suite, home gym, or additional living area.

Because it is optional, this space allows you to reduce initial build cost and finish it later when needed. It also works well for storage if left unfinished. This flexibility is one of the key advantages of the plan.
