Sky-High Living: The Rooftop Deck

One of the standout features of the Mountain XL is its signature rooftop deck. Accessed via a telescoping ladder, this 8.5′ x 6′ cedar-planked oasis with stainless steel cable railings effectively doubles your usable living area. It’s the perfect spot for stargazing or enjoying panoramic views, solving the common tiny house problem of feeling ‘boxed in.’

Artisanal Craftsmanship and Sustainable Materials

Inside, the Mountain XL feels like a modern woodland retreat. The kitchen features breathtaking live-edge black walnut and epoxy countertops, paired with a composite stone sink and a touchless faucet. The home is insulated with carbon-sequestering hemp wool and features custom cedar planking throughout, creating a space that is as green as it is beautiful.

Smart Storage and High-Performance Engineering

Built on a 2021 10k tandem drop axle trailer using light-gauge steel framing, the Mountain XL is significantly lighter and more resilient than traditional wood-framed tiny homes. The design features smart storage solutions throughout, including soft-close drawers and a space-saving stow-away ladder for loft access.

Natural Light and Modern Amenities

Natural light floods the interior through a massive Velux egress skylight over the loft and a second fixed skylight over the bathroom. The climate is perfectly controlled by a 12k BTU Mr. Cool minisplit, and hot water is provided on-demand by a Girard propane system. The bathroom even features a full-size 32×32 cedar plank shower, adding to the luxury spa feel of the unit.
