The Apollo is available in widths of 3, 4, 5, 6, 8, 10 and 12 metres. The length is unlimited and can be increased in increments of 5 metres. The roof canopy comes in white opaque (non-permeable to light) 80% or transparent and the white sidewall panels, with or without windows, have sliding fixings to allow them to be open or closed.
The Apollo is equipped with the Neptunus raised cassette floor and the special Neptunus rain gutter tensioning, which means the canopy stays taut at all times. In addition to being used as a stand-alone structure the Apollo can be connected to other Neptunus structure styles to act as a passageway.
