Pergola vs gazebo vs pavilion: compare the roof and intended use
Gazebo, pavilion and pergola labels vary between suppliers and markets. Compare the actual roof, structure and project requirements rather than assuming the name describes one standard product.

Start with the roof you want to use
If you want to adjust overhead shade by rotating roof blades, review a louvered pergola. If you want fixed overhead coverage, review the fixed-roof garden pavilion. Gazebo commonly describes a freestanding garden shelter, but the label does not specify materials, dimensions or tested weather performance. Read the particular supplier specification.
Compare shade, rainwater and side options
An adjustable louvered roof and a fixed roof have different operating patterns. Rain management still depends on roof details, drainage, installation and site conditions. Screens or glass require model-specific compatibility review. A roof or side enclosure alone does not turn an outdoor shelter into a conditioned indoor room.
Freestanding and attached layouts are project decisions
Check post positions against furniture and walking routes. A wall-mounted layout requires review of the connection and the existing building; a deck or paving surface is not automatic confirmation of a suitable foundation. Identify responsibility for foundations, connections, drainage and electrical work before manufacture.
Compare equivalent quotations
TTH publishes separate product unit prices for the louvered families and the hardtop pavilion. Compare the selected structure and size, accessories, packing, transport and local installation scope. A cheaper headline figure may refer to a different area definition or a narrower delivery package. Do not infer brand equivalence from similar photographs.
