An urban transformation and construction method is disclosed that creates a tropical style swimming lagoon at vacant and/or abandoned sites. The transformation includes demolishing at least part of the vacant or abandoned site, excavating material from within the site; forming a basin for a large water body having a surface area of at least 3,000 m2, and constructing water containment walls on a first section of the basin to form a waterfront perimeter. The shape of the waterfront perimeter is mainly curved, the basin has a maximum width of 300 meters, and the bottom is covered with a non-permeable material. A sloped access area is constructed in a second section of the basin to form a beach. A barrier is constructed to control access into the area including the beach. At least one recreational facility is constructed including restaurants, bars, kiosks, stores, and/or cafes about the waterfront perimeter.

A method for changing acoustics of a performance space may include mounting a plurality of panel assemblies to a ceiling or a portion of a ceiling of the performance space. Each panel assembly of the plurality of panel assemblies may include one or more acoustic panels. The exemplary method may further include changing a distance of the one or more acoustic panels of each panel assembly of the plurality of panel assemblies from the ceiling by coupling the one or more acoustic panels of each panel assembly of the plurality of panel assemblies with a first actuating mechanism, and actuating a linear vertical movement of the one or more acoustic panels of each panel assembly of the plurality of panel assemblies along a first axis perpendicular to the ceiling utilizing the first actuating mechanism.

A theatre construction comprises a seating area 120 for an audience, a circular support structure 134 surrounding the seating area and mounted above the seating area and a plurality of arcuate screens 135 suspended from the circular support structure. The screens 135 are mounted to the circular support structure 134 on rails for allowing movement of the screens about the seating area.

The room includes: a ceiling; a floor; and a wall having a pair of wall surfaces opposite to each other, and another pair of wall surfaces opposite to each other in a direction intersecting the pair of wall surfaces. One of the pair of wall surfaces and the other pair of wall surfaces has a window. The wall surface opposite to the wall surface having the window has arranged thereon a first screen. An inner side of the window, and a projection-side surface of the first each has arranged thereon a polarizing plate. An absorption axis direction of a polarizer of the polarizing plate of the window, and an absorption axis direction of a polarizer of the polarizing plate of the first screen and/or an absorption axis direction of a polarizer of the polarizing plate of the second screen are substantially perpendicular or parallel to each other.

A movie theater auditorium is disclosed with reclining or reclined seats, whereby patrons are viewing a screen that is elevated and tilted toward the viewing audience. Comparative to traditional movie theaters with vertical screens with fixed or reclining chairs, exemplary embodiments provide a more natural viewing angle and line of sight for the viewing audience. Some embodiments are disclosed which employ repurposed shipping containers as structural elements of a cinema.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex, with surrounding entertainment, educational, sports, and commercial facilities, the complex having controlled public access and providing the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

The removable roof system includes a set of guy ropes (10), each of the guy ropes extending between a top anchor point (2) and a bottom anchor point (3) of a structure to be covered, a velum (1) mobile between a deployed configuration in which the velum covers the structure to be covered and a retracted configuration in which the structure to be covered is uncovered, and a set of carriages (20) to which the velum is attached, arranged so as to be moved along the guy ropes of the set of guy ropes between the top and bottom anchor points in order to cause the velum to pass between its deployed and retracted configurations and comprising for each of the guy ropes of the set of guy ropes at least one motorized carriage, at least one motorized carriage cooperating with the associated guy rope by meshing or by alternating wedging.
