- Material choice — cedar, redwood, composite, and aluminum typically cost more than basic pressure-treated lumber
- Roof and shade — open rafters are cheapest; polycarbonate or solid roofs add material, flashing, and labor
- Footings — surface mounts save money where allowed; concrete piers or helical anchors add cost but improve stability
- Electrical and permits — fans, outlets, and lighting require wiring and sometimes permits and inspections
