Manual louvered systems near a standard-kit footprint

Compare the Hansø PRO+ sizes against exact outside-post dimensions. Also inspect larger Purple Leaf Athena configurations; use multiple bays or custom systems only after resolving posts, drainage and load path.

EVIDENCE GATE

Verify the existing slab against the exact baseplate, anchor, edge-distance and load assumptions. “Concrete present” is not structural verification.

A shortlist is a research starting point, not a product endorsement. It uses project type and footprint only; local wind, snow, code, stock and installer responsibility can eliminate every option.

Turn the result into comparable quotes

Send the copied brief to every seller and installer. Ask them to mark kit, delivery, foundation, labor, electrical, permit/engineering and accessories as included, optional, owner-supplied or excluded.

Verify outside-post dimensions rather than nominal roof size.
Require exact-model wind/snow conditions and the corresponding anchor detail.
Confirm freight handoff, unloading, damage inspection and missing-part responsibility.
Identify the party responsible for permits, inspections, electrical commissioning and drainage discharge.

Read the kit-price and material cost guide, compare the 10×10, 10×12 and 12×16 installed scopes, then use the wind and anchoring gate. Motorized project? Close the electrical and permit checklist before deposit.
