CS1 Crestview is a community leisure space designed by local design studio HA+MA, which is located in the rolling hills of Los Angeles, California, USA. It is based on the landscape, the environment, and the designer's thoughtful design. The site offers panoramic views of the city and the mountains in the distance. The small decorative building is hidden in a lush oak forest, like a piece of wood floating in the woods, blocked by bricks on the west side.

Made around a palette of simple materials – Concrete, Alaskan Cedar, and handmade brick – CS1 is constructed around a series of keyframed views and axis’, allowing circulation of visitors and light while large glass walls slide away, opening the space to both its immediate and distant surroundings. The interior and exterior flow together both spatially and materially as the roof and floor planes sweep through to the landscape beyond.

Utilizing exposed glulam structural members and custom, hidden steel plates, and connections, a dramatic yet intimate space is formed from the tight and considered plan. The structure itself provides new utilities and amenities while the striking cantilever offers shade, a place to socialize, and frames dramatic views across the Southern Californian landscape.
