01Define the architectural job before choosing the model
Record the clear spans, column positions, building relationships, view corridors, use of the space and whether the roof is residential, hospitality, resort or commercial. ARKEN can then be reviewed as part of the architecture rather than as a catalogue pergola.
Large spans and reduced-column layouts should be driven by the project geometry and verified structural pathway, not by copying a reference dimension from another site.
02Choose between rotating and retracting louvre behaviour
A rotating louvre roof changes shade, ventilation and closed-roof rain management while keeping the blade field in place. The ARKEN open-sky pathway also retracts the louvres, creating a substantially more open roof condition.
The right system depends on how much open sky is required, the stack or travel zone, controls, maintenance access and the architectural appearance expected when the roof is open.
03Plan large-span and multi-bay structures as one system
Linked bays, wider members and fewer columns affect drainage, structural reactions, foundation locations and how the structure meets the building or landscape.
Provide plans and elevations early so bay logic, post positions and roof direction can be reviewed before finishes or surrounding works are fixed.
04Coordinate glass and screens with the original structure
Glass enclosure, blinds and other side-control systems change the way an outdoor room behaves in wind and rain. Likely enclosure should be declared before final structural review.
Thresholds, glass panel sizes, blind tracks, door movement and service access should be coordinated with posts, beams and drainage rather than added as unrelated accessories.
05Use project-specific evidence for performance claims
Reference dimensions and manufacturer data are useful for early planning, but final wind, snow, drainage, coating, motor, structural and compliance claims depend on the exact ARKEN configuration and destination.
Apollo supplies the selected system and current supporting documentation. Local foundations, installation, electrical work, drainage discharge, engineering and statutory approvals remain separately defined unless included in writing.
