Why area alone is not enough
Two pergolas of the same size may need different structural profiles, motors and installation details. A reliable quotation follows a site survey and technical layout.
System type
Retractable fabric roofs and bioclimatic louvre systems use different mechanics. Membrane specification, blade design, movement and automation all affect cost.
Span and structure
Large openings change profile sections, post count and modular division. Anchoring, steel reinforcement and special connection plates cannot be priced from area alone.
Optional equipment
LED lighting, weather sensors, smart-home links, zip screens and glazing are separate choices. Planning future additions early avoids unnecessary alterations later.
Comparing quotations
Check alloy, finish, motor, warranty, glass and installation scope. Consider lifetime value and service access, not only the lowest starting figure.
