440 Sq Ft Custom Retirement Tiny House with Movable Bathtub and Heated Floors

Sean and Kristi Hensley built their custom retirement tiny house after a lifetime in construction and several smaller-scale projects, including converting a cargo trailer for cross-country travel. When they decided to downsize, they brought decades of building experience to their own home.

Measuring 440 square feet (40′ x 11′), this home showcases clever features and luxury design elements throughout. The extra-wide 11-foot width makes a significant difference in how spacious the interior feels, allowing for features that wouldn’t fit in a standard 8.5-foot-wide tiny house.

Spacious Bedroom with Hand-Built Reclaimed Wood Bed

The 11-foot width makes a significant difference in the bedroom, allowing for a spacious feel that narrower tiny houses can’t achieve. The bed was hand-built using reclaimed materials, adding character and sustainability to the design.

    This is the most brilliantly designed tiny home I’ve ever seen!!!!!
    It really is exquisitely done and incredibly practical with style style style to boot!
    Congratulations on a unique, perfectly made tiny home.
    I especially love the way you have incorporated your artwork. As a fellow collector of exquisite carvings myself as well as unique ethnic art pieces, I have wondered how I could incorporate them into a tiny home and now I see how.
    Thank you for sharing your extraordinary home.
