Manufacturer IdentifiedYes
Used for shelter in the U.S.?Yes
Prior use examplesOriginally designed as an even pavilion, it found its first application as a shade structure for a house in the Silver Lake neighborhood of Los Angeles.
Prior use commentsThe Client house found that not only is it good for shade during the day, but it also provides a sense of shelter and privacy at night.
Building experience commentsAs a Pre-Fab structure, there is not really any building as much as there is assembling.
Intended use casesIt could be used as a shelter for an individual or several of them could be arranged around an open shared space to create a sense of community
R-value (insulation)0-10
Risk CategoryN/A – Temporary Use
Roof Load (PSF)0
Indoor Clearance Height (ft)8

Other Structural / Safety CommentsAs long as it is put up correctly there should be no issues.

Materials Used / Made of:Steel
Disassembly / Assembly Comments:You do need a ladder and it goes faster if you have someone helping you.
Ideal Mounting SurfacesSoil (Dirt/Grass), Asphalt / Parking Lot
Anchoring ProcessNo need to anchor — the steel is heavy enough to hold it in place. But for added assurance, you could use sand bags.
