TLEEDESIGN is joining architects, Harley Ellis Devereaux to develop a new concept masterplan for the LCLS (Linac Coherent Light Source) Gateway Project. Located within the scenic rolling foothills of SLAC National Accelerator Laboratory in Menlo Park, the LCLS facilities were constructed in 2008. The LCLS Program is the largest science experimental program at SLAC, with approximately 2,000 users and visitors every year. This Gateway Project will include services for Architectural, Landscape, Electrical, and Civil elements.
