Metal pergola vs sunroom

Cost: A fixed canopy costs less per m² than an opening louvre roof - use the price calculator for an indicative figure.
Flexibility: Fixed canopy is always covered; louvre roof adjusts to conditions on demand.
Maintenance: Fixed canopy needs only cleaning and a fixings check; a louvre roof has a motor, drainage channels and pivot points to keep serviced.
Consent complexity: Both depend on the specific structure, but the electrical work for a motorised system is an extra factor to plan for.
Lifespan: Both use aluminium framing and are built to last well beyond their warranty period with basic care - fewer moving parts on a fixed canopy is one reason it needs less attention over time.

One is an outdoor roof, the other is a new room. The choice comes down to whether you want to be outside under cover or inside looking out.
