Before You Begin

Check with your local building department to see if a permit is required for the addition of a gazebo and if there are specified types of foundations for their construction. A gazebo is usually built on a concrete slab or a raised wooden deck. Some building codes require that the foundation must be anchored to concrete footings, while in other areas the structure can be simply set in place on a foundation of cinderblocks.

  • Step 1 : Prepare the foundation

    Follow the directions from the kit manufacturer to layout the outline for the foundation. Follow the requirements of your local building codes and prepare the foundation for the gazebo. In general, for a cement slab or wooden deck, the cement posts and footings should be at least 10 inches square and set to below the frost line.

  • Step 2 : Lay out all the components of the kit and read the directions

    Spend a lot of time becoming familiar with all the parts and hardware of the kit. Group like parts together and assemble all the various hardware and screws according to their type and size.

  • Step 3 : Assemble the floor kit

    Depending on how it is engineered, follow the directions to assemble the floor and fasten it to the foundation.

  • Step 4 : Assemble the wall and roof components

    Follow the directions to assemble the walls and roof units. First erect the walls to create the outer framework of the gazebo. Use the fastening hardware to secure them to the floor assembly. You will probably need help to lift the roof sections and set them in place atop the walls. Fasten the cupola to the roof and install any additional details on the roof.

  • Step 5 : Add additional building components

    Use the hardware and fasteners provided to secure the remaining components, such as the corner brackets, railings, posts and fretwork. Use silicone caulk to seal any open joints and sand any rough surfaces. Follow the instructions about sealing or finishing the gazebo with a protective finish.
