Alton cedar structures bring you unique features including a fantastic smell, aluminum base with protective design, gutter and downspout, Mortice-Tenon and tongue-groove framing joints, high eaves, toughened safety glass, and hinged lockable doors. Call us at 732-806-7959 — we can help find an installer in your area, offer exclusive accessories and discounts, and answer any questions.

The Fusion Cedar Shed/Greenhouse combo combines the best of both worlds — this unique design seamlessly integrates a greenhouse with a shed, providing a dedicated area for plant cultivation alongside secure storage for gardening tools and equipment. An optional sliding door between the shed and greenhouse, a lockable hinged shed door, and a greenhouse sliding door with a tall design and low threshold enhance functionality. The Alton Fusion Greenhouse Shed Hybrid is a practical solution for gardeners looking to maximize space and organization.

Crafted from Western Red Cedar and aluminum, this Fusion model offers superior durability and insulation, creating a stable growing environment with reduced temperature and humidity fluctuations. The tall structure and dual-purpose layout make it an ideal choice for gardeners who want functionality without sacrificing style.

Choose Your Size:

11×11 (115 sq. ft.): 10'10" wide x 10'7" long x 8' high — our more compact Fusion, still with a full dedicated shed and greenhouse side.

11×13 (138 sq. ft.): 10'10" wide x 12'8" long x 8' high — more room on both the storage and growing side.

Both sizes are available with the door configured on the left or right side to match how you plan to approach the structure.

  • Dual-Purpose Design: Combines a greenhouse and shed in one structure, optimizing space for both plant cultivation and storage needs.
  • Premium Cedar & Aluminum Construction: Combines the beauty of Western Red Cedar with an aluminum base for durability and rot resistance.
  • Enhanced Insulation & Durability: Aluminum bar capping and thick glazing timber bars improve insulation and overall stability.
  • Includes: lockable hinged door, 2x sliding doors, 2x large windows, 2x louver vents, and 2x roof vents with auto openers.

About Alton by Exaco

The Fusion is built by Alton UK, a British cedar greenhouse maker in continuous production since 1921, imported exclusively to the U.S. by Exaco Trading — World of Greenhouses is an authorized Alton dealer. Every Alton structure shares the same build quality: grade-1 Western Red Cedar (no knots) dipped to resist water absorption, a steep 45° roof pitch so snow slides off, tongue-and-groove assembly with solid aluminum gussets at every joint, an aluminum base profile that lifts the frame 1" off the ground, aluminum bar capping, 3mm tempered safety glass, pre-assembled doors and windows, and automatic enrollment in a 10-year warranty.
