The direct answer
Select restaurant terrace shade around guest comfort, service routes and daily operation. Compare retractable fabric roofs and louvered pergolas against your seating plan, then decide where side screens help. The useful covered area depends on circulation, post positions and sun direction, not just the roof’s outer dimensions.
Draw the service plan before the roof
Place tables, chairs in use, staff routes and doors on the same scaled plan. Check roof supports against these movements and keep accessible routes and required exits in the local design review. Do not estimate additional seating only by dividing the proposed roof area by a table footprint.
Match the roof to the service periods
Observe the terrace during breakfast, lunch or evening service as relevant. A retractable roof can suit a brief that prioritizes an open-sky setting when conditions allow. A louvered roof offers adjustable overhead shading; side screens address a different problem where low sun enters through the perimeter.
Make operation manageable for staff
Assign who checks conditions, operates each zone and reports faults. Ask for labelled controls and a demonstration at handover. Document what staff should do during unsuitable weather or power loss using the specific system’s instructions. Lighting, heaters and screens need coordination with the responsible installers before they are added.
Plan installation around the business
Agree the delivery access, storage space, noisy work and reopening checks with the venue team. Separate product arrival from completion of foundations, electrics and commissioning. Include cleaning access and replacement-part procedures in the operating budget, then evaluate the proposal against your own usage assumptions rather than a promised revenue increase.
