Hotel Magdalena's sloping architecture is designed to recall the gently inclined landscape of the nearby Barton Springs, a popular outdoor swimming spot.
Bunkhouse Group and Lake Flato incorporated elements from both mid-century Austin icons in the interiors.
Guests are welcomed at two lobbies. The valet lobby is filled with pieces such as a Marset Dipping Lamp and a plush 1970s Harvey Probber sofa named Deep Tuft, designed to mimic the tufted seating found in luxury cars.
Hotel Magdalena's main lobby mixes design elements by renowned brands and local makers.
Unstained white oak tambour forms the main lobby's desk, behind which colourful ceramic pots by local designer Rory Foster are placed, as well as the hotel's own book collection sourced from Half Price Books.
"When we were styling the lobby, we pictured a person who lived in an effortlessly cool house on Lake Austin," said Bunkhouse Group's vice president of design and development Tenaya Hills.
"We thought about what they would collect on their travels, what they found interesting, and what books and records they'd have," Hills told Dezeen.
A scattering of 70s original collages by the late Graham Harmon also decorates one of the lobby's white walls. It is understood that Harmon painted the works in Austin.
"The story of the hotel is the story of Austin," said Hills. "The buildings are inspired by 1950s Austin lake houses, which then informed the materials you see and the furniture system we designed for the guest rooms."
Bespoke beds are built-in and crafted from walnut wood, and inlay desks separate each room's bed from its small living space.
Poured concrete floors with exposed aggregate echo rocky river beds, while wooden ceilings maintain the hotel's lake house design.
Bathrooms tiled in blue, red, yellow or green inform the colour of each room's more subtle design elements, such as various Christian Rathbone throw pillows adorned in what Hills describes as "hippie textiles," and custom bedside lighting by David Weeks.
Guest rooms feature individual black and white photographs by local photographer Scott Newton. Newton's images capture live music in Austin.
Hotel Magdalena's swimming pool is accessed by various exposed elevated walkways. Poolside umbrellas, loungers and side tables by Kettal blend with the exterior setting.
Overlooking the pool, the hotel's outdoor bar area is a colourful space with soft seating by Expormim and clusters of umbrellas.
"We went for a palette of natural materials – stone and wood and a high gloss ceramic tile. The main colour woven throughout is green," said Hills.
Like in the hotel's eclectic lobbies, vintage treasures made from coloured glass and ceramics line the restaurant's bar shelves.
Local craftsmanship is celebrated in the form of a bespoke bench by Litmus Industries and artwork by Graham Harmon and Michelle Billette sourced at Round Top Antiques Fair.
Bunkhouse Group is a hospitality company based in Austin. Lake Flato is an American architecture firm founded in 1984. The firm recently designed a marine research centre in Mississippi formed from six pine buildings.
