It is an outdoor pavilion, made for SketchUp 3D Challenge 223. About the vault: base supports are from reinforced concrete, the arches are from laminated wood, girders are from wood, the lid is from lath - inside, and tin - outside. Under the vault there are some free space for various events (such as dancenight, dinner, rest, meeting, study, conference or whatever). Also take a moment to perceive this is not an isolated building but open-air, outdoor, pavilion. However it contains unusual extras like solars, internet and power connections, resting on the outdoor furniture set the wind, the rain, the sun and the nature can touch you. :)
