Sale price$689.00

Package Type: Study Plans

The Twin House Barndominium plan is a unique design. The floor plan incorporates an open-concept living and dining room on the main floor and two bedrooms on the second floor. Every square foot of this floor plan is designed to be functional yet incorporate the outdoor beauty of the landscape.

Featuring a sleek black exterior that exudes modernity, the Twin House Floorplan seamlessly integrates with the surrounding landscape. Inside the barndominium, you'll find a spacious open-concept living room with three bedrooms, two bathrooms, two offices, and a play area. Combined with the ADU, the entire barndominium plan includes four bedrooms. This plan is designed with a conventional wood framing system with black siding that keeps the building process simple.

The Twin House Plans were initially inspired by a barn house with a modern touch. The two basic-shaped structures joined by a screen porch create a unique and captivating modern and traditional look. The black siding and roof give the property a sleek and contemporary feel that contrasts beautifully with the light wood accents. The key living room space leads to a small covered patio.

One of the standout features of the Twin House Plans is its use of standard door and window sizes, making it easier for owners to source materials locally and manage their construction budget. This barndominium plan is perfect for creating a dream house with a unique design. Whether you prefer traditional homes or modern designs, the Twin House Plans can cater to your taste and style.

Main Residence

Step inside the Twin house; the living quarters are designed with an open floor plan living space and dining room with high, vaulted cathedral ceilings. The large double-height windows offer a view from the great room to the outdoors, and a sliding door leads to a deck. The open floor plan design creates one ample space for all the living spaces.

The L-shaped kitchen includes a center island and a regular-sized pantry. There is a powder room and closet for storage on the ground floor. Storage is also available under the stairs. Other features include a dedicated dog washing station, a laundry and mudroom, a master suite with a walk-in closet, and a bathroom with a separate wet room containing the shower and bathtub.

The second floor includes two bedrooms with tons of closet space, two offices, a play area, and a bathroom. These two home offices perfectly adapt to the new lifestyle of working from home. The floor plan has additional play spaces that can be enclosed as a game room or converted into a four-bedroom house.

 Screen Porch

The 164 sqft screen porch can be accessed from the side of the main residence and is designed for entertaining guests or hosting dinner parties. The patio offers protection from mosquitoes and other insects, even on rainy days. The screen porch is an extension of the living quarters for the beautiful summer days.


The Twin House Plans also include an ADU (accessory dwelling unit) incorporated as a unique feature of this floor plan design. The ADU has two spaces. One is a multi-functional space that can house another bedroom with enough room for a work desk. It has a kitchenette, bath, and a small cozy loft bedroom - perfect for accommodating extended family or rental income. The other part is a workshop and storage with a French garage door. These spaces are independent of the primary residence and can only be accessed outside.

Whether you're looking to build a new family home or invest in a rental property, Twin House Plans is one of the perfect style house plans for those seeking luxury living with a functional and eco-friendly design.
