Establish a premium commercial-grade workspace, backyard tiny home, luxury executive office, or climate-controlled hobby studio with the max-insulated Duramax 22' x 10' Flat Roof Building (SKU: 30872). Specifically engineered to function as a fully insulated standalone Accessory Dwelling Unit (ADU) or high-capacity outdoor workshop, this heavy-duty prefabricated building delivers an incredible 1,430 cubic feet of walk-in storage volume. It stands as the ultimate, zero-maintenance alternative to traditional, expensive brick-and-mortar construction or custom wood framing.

Unlike standard thin-walled tin sheds that offer no climate protection, the Duramax 30872 Insulated Building features pre-painted galvanized inner and outer steel walls structurally fused with thick, fire-retardant polyurethane insulation. This advanced thermal composite technology drastically limits heat gain during scorching summer months and retains heat during freezing winters, ensuring a comfortable interior climate ideal for all-weather conditions. This rigid structural frame easily supports mounting a split-system heating and cooling unit.

Premium Structural Engineering & Design Benefits

  • Modern Flat Roof Design: Features a clean, low-profile architectural flat roof slope that provides a sleek, contemporary backyard aesthetic while meeting strict local neighborhood height restrictions.

  • All-Weather Thermal & Acoustic Performance: Thick, high-density polyurethane insulation provides outstanding thermal resistance and superior acoustic sound-dampening, making it perfect for loud workshops or quiet backyard office work.

  • Heavy-Duty Metal Foundation Grid Included: Comes standard with an engineered metal floor foundation kit, allowing rapid structural construction on just about any flat, level surface without the strict necessity or high expense of pouring a solid concrete pad.

  • Customizable Layout & Deadbolt Security: Features a highly secure entry door outfitted with a heavy-duty deadbolt lock system that can be custom-configured on any side wall panel location during assembly to fit your specific yard layout.

  • Elite 30 lbs/sq. ft. Certified Snow Load: Built with one of the strongest do-it-yourself structural truss grids available on the consumer market, engineering-certified to withstand intense winter snow accumulation and high winds.

    Questions & Answers

    Have a Question?

    Ask a Question
    • How tall is the shed?

      Exterior height 92 inches

    • Can the door and the window be placed in a different wall location?

      Yes, you can locate them in other places along the front of the shed.  If you look at the other pictures on the product page for this shed you can see some examples of this.

    • Do ypu have to use the floor frame if placing on existing cement and can larger doors such as patio doors be added on site ?

      The floor frame would not be required, but please keep in mind the purpose of the foundation kit is to help in the building process.  It is critical that the shed is built on a flat and level surface.  Even a small out of square condition at the base of the shed can result in screw holes not lining up at the top of the shed.

    • Will the 22x10 building be back in stock and can you connect two buildings together thanks.

      There are currently 4 of the 22x10 gable roof buildings in stock.  The flat roof will be back, but we do not have a date at this time.

      You can not connect two buildings together, but there are 3 ft extension kits you can buy that can extend the length to whatever you like in 3 ft increments.

    Is the Duramax 22' x 10' Flat Roof Building fully insulated?
    Yes, the Duramax 22' x 10' Flat Roof Building (SKU: 30872) is engineered for all-weather comfort. It features thick, fire-retardant, CFC-Free polyurethane insulation layered between pre-painted galvanized inner and outer steel walls, offering exceptional thermal and acoustic performance for year-round use.
    What is the advantage of the flat roof layout on the Duramax SKU 30872?
    The flat roof style offers a contemporary, modern architectural profile that perfectly complements high-end homes. Additionally, the lower peak height makes it easier to comply with strict local HOA or residential building code height limitations while maximizing internal walk-in volume.
    Can the door location be changed on the Duramax 22x10 Flat Roof Building?
    Yes, absolutely. The secure entry door features a modular layout with an integrated deadbolt lock system. During the bolted tongue-and-groove assembly process, the door can be configured on any side wall panel location that best suits your walkway configuration.
