The PS1 prototype telescope occupies the same site as the old NASA Satellite Laser Ranging system, which was decommissioned in 2004. PS1’s installation in the south dome of the LURE Observatory started in July 2005. The north dome of the LURE Observatory, which formerly housed the University of Tokyo's Magnum Telescope, is the future home of PS2.
The enclosure was manufactured by Electro Optic Systems Pty Ltd (Australia) and assembled on site by Taisei Construction Corporation of Maui.
The telescope itself was built by EOS Technologies Inc (Tucson).
The construction photographs may be compared to the following cut-away drawing of the PS1 building.
