Personalized and Handcrafted

Our storage sheds and utility sheds are not your average "Big Box" quality sheds. In fact, these sheds are made of the highest quality material and built to the same specs that houses and barns are built to.

Outdoor living which was once considered a luxury is now becoming common. In addition to sheds, we also build outdoor living spaces such as pool houses, man caves, studios, she sheds.

Each shed is built to order according to the customer’s specific needs. Meeting our customers quality expectations is a must but we strive to exceed them. Our craftsmen take pride and work with integrity to ensure that each unit is built as if it were their own.

Quality Materials, Customer Service

Our goal is to create beautiful, durable and long-lasting sheds. For this reason, we are dedicated to sourcing only Premium Grade materials. The DuraTemp siding has a 50-year warranty and the paint we use is water-based and has a stain guard additive which helps to permanently block stains and odors.

From start to finish, our customers will testify of a great experience. We are dedicated to being informative, transparent and helpful. We understand that the purchase of a structure like this is an investment and we will give our customers the time they need to decide. We are here to help you.

Thank you John and team from Cornerstone for building us such a beautiful shed. It was delivered on time and as promised. They made sure everything was installed properly and the area where they were working was cleaned before they left.
