Little Cottage Company 12 x 12 Octagon Garden Shed Greenhouse 

The Little Cottage Company 12x12 Octagon Garden Shed Greenhouse Kit is perfect for people who want to improve their backyard game without spending a lot of money or having to do a lot of work. This garden shed greenhouse kit is built with quality workmanship and attention to detail. It will provide function and beauty to any outdoor space. The octagonal design offers something that no other traditional square structure can match. With this garden shed greenhouse, you can have flowers blooming in colder climates and bigger harvests from less space. You don't even have to leave your own property.

Delivery Instruction

Lead time for production is 2 weeks or less. Your shed will be delivered in 2-9 days depending on the distance from our site in Ohio to your home.


It is curbside delivery. Although our trailers and carriers most often come with liftgates to unload your shed, there might be certain factors such as terrain, road clearance, or the weight of the pallet being too heavy for the liftgate to unload which might prevent that from doing so. We highly encourage you to have 2-3 people ready on the day of the delivery to manually unload the pieces on the pallet one by one. Each individual piece would weigh around 1-100 lbs. so it is manageable to have one person on the trailer carry down the piece and the other receives it from the curb. Thank you for your understanding and for choosing Homestead Supplier.


The 12X12 Octagon Garden Shed Greenhouse Kit has to be the center of attraction in your garden with its awe-inspiring design. Only separated by a wall, you can use it as a shed and a garden. Topped off with a copper finial and a dome, it also features durable tempered glass windows for maximum light coverage.

    Ask a Question
    • Can 7 sides be windowed?

      For customization requests, please email us at

    • Can the sidewall height be increased to 8' and how much would it cost to ship to 34688

      Unfortunately, the 12x12 Octagon Greenhouse Shed cannot be upgraded to 8ft high due to freight trailer opening restrictions.

    • Hello, I have a couple questions. I live in Indiana, do you offer installation? I'm interested in the 12' Octagon greenhouse. Also, canI buy the plans and specs so I can get it approved with my HOA?

      We do not offer installation services just yet. We suggest checking for this service, a lot of our customers have used them for assembly.

    • What is the snow load for this unit? Can it withstand high winds?

      Unfortunately, we do not have the snow load unit information for the greenhouse. The wind rating of this model is close to 120mph.

    Don't Take Our Word For it! Here's What Our Customers Think:

    Hats off to Homestead Supplier for superior customer service - these guys go above and beyond to answer all my questions. We purchased the Beach House shed for some extra storage but ended up using it as a backyard playhouse for the kids :). Now we have to buy another shed lol... The shed is great, sturdy, and would recommend to others.

    - Sam B.

    I found the buying experience to be far better than expected. Very easy to order, received immediate order confirmation, excellent customer service, order showed earlier than expected and in excellent condition. Would definitely recommend

    - Dean G.

    After 7 months of waiting for our pool to be completed, we are thrilled to have gotten our new shed built. It perfectly completes our backyard renovation. We love it! The instructions were clear, and the building is sturdy. We’ve had a number of inquiries about who we bought our shed kit from.

    - Karen E.
