The dual-branded Hyatt House & Hyatt Place LAX was originally built and designed for office use in 1967. After a long-awaited adaptive reuse, the 15-story, 80,000-SF concrete building—including a basement—now hosts two hotels that provide unique accommodations, a total of 401 rooms, to satisfy the specific needs of their guests. Both feature many key features for the enjoyment of their guests, such as a rooftop swimming pool, spa, bar, enclosed lounge and even a branch of Greenleaf Kitchen & Cocktails on the lobby level—not to mention a new upscale concept from Greenleaf’s chef Blake Clevenger, ShoresLAX, on the rooftop. The design adds new interior light wells throughout the height of the building and an elevator service that extends to the roof amenity level. Miyamoto’s retrofit design includes new concrete shear walls and foundations, and the interior columns were wrapped with fiber reinforced polymer. The primary challenges of this project were to preserve the historic character of the decorative concrete columns on the building facade and to add the rooftop amenities with minimal structural strengthening.
