booth layout 3d model

Create a top-down 3D booth layout, 4 meters wide and 4 meters deep. The booth has solid walls on the left, right, and top sides, with an open entrance on the bottom side. In the top-left corner, add an interior vertical wall 2 meters long, creating an L-shaped inner niche. The distance from this interior wall to the right wall is 3 meters. Inside the lower part of the niche, place a hinged door that opens inward, shown as a curved swing arc. All walls are straight, orthogonal, and measured in meters. Minimal, clean architectural style, accurate proportions.
