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.
