Adding a Cupola to the Savannah Pavilion could be tricky - Not the actual cupola itself, but determining what size you need. The size of a cupola is usually dependent on the length of uninterrupted roof line. The standard formula is for every foot of roof, should equal 1" of one side of the square cupola base. So a 30' long pavilion should have a 30" square cupola, and a hundred foot long would have a cupola with a base of almost 8'. Talk to a Project Advisor for information concerning the correct size of cupola and pricing.
