Lamar Johnson Collaborative (LJC) fully re-imagined the former worldwide headquarters of a leading pharmaceutical company into the U.S. headquarters of Horizon Therapeutics. The campus project is composed of three main buildings totaling 670,000 SF. The entire facility has received a rating of LEED GOLD.

Horizon and LJC partnered to create a single, unified campus for employees. The entire campus integrates ease of employee collaboration, teaming while providing flexibility of departmental headcount growth while maintaining all critical segment adjacencies. Each of the three buildings are connected by a single, continuous ground floor concourse section that is composed of conferencing, teaming and learning spaces.

These spaces further emphasize and promote Horizon’s brand and culture. These interior amenity spaces include a “Starbucks-style” coffee bar, full food server/café, VIP meeting lounge, Tech Pub for staff, , shared multi-purpose spaces, game lounge and bowling alley.

The campus is truly designed as a destination for employees to work each day. Creating a campus and workplace environment that allows Horizon the ability to attract the “best and brightest” talent will always be paramount to Horizon’s leadership team. Interior amenities are coupled by exterior amenities that include a daycare facility, Bocce Ball court, employee garden, softball field, basketball court, and a one-mile nature trail represent only the starting point of future developments amongst their 70–acre site

Horizon’s new campus expresses its brand and celebrates their mission of putting patients at the center of their work. Providing their employees with the best and most technologically advanced environment allows Horizon’s employees the opportunity to deliver the highest level of care to patients.
