Hotel On Phillips Sioux Falls is a four-star boutique hotel located at 100 North Phillips Avenue at the intersection of 9th Street and Phillips Avenue in downtown Sioux Falls, South Dakota. Constructed in 1918 as the nine-story Sioux Falls National Bank—which stood as the tallest building in South Dakota at the time of its completion—the Neoclassical landmark underwent a full centennial restoration in 2018. Today, the property houses 90 custom-configured guest rooms and suites alongside original early-20th-century banking vaults, marble columns, and the ground-floor cocktail lounge known as The Treasury.
What to Expect at Hotel On Phillips Sioux Falls
Stepping through the main entrance on Phillips Avenue brings guests directly into the historic banking lobby, where high coffered ceilings, marble floors, and brass accents preserve the building’s 1918 commercial heritage. Because the upper seven floors originally functioned as professional office suites, the 90 guest rooms and luxury suites feature varied architectural footprints rather than identical cookie-cutter layouts. Standard King and Double Queen rooms include custom Art Deco-inspired furnishings, plush pillow-top mattresses, walk-in tiled showers, smart televisions, and Keurig coffee makers. Higher-tier accommodations—including the Junior Suites, Whirlpool Suites, and the signature two-room Presidential Suite—offer expansive corner views over downtown Sioux Falls, soaking tubs, and separate living areas suited for extended stays or special occasions.
On the lobby level, Hotel On Phillips anchors its culinary and social experience around the building’s original bank vaults. The Treasury operates as the property’s lounge and restaurant, specializing in craft cocktails, regional beers, curated wines, and elevated small plates. Directly inside the primary walk-in steel vault sits The Stronghold, an intimate seating parlor enclosed by the original multi-ton circular vault door. Additional private gathering spaces reflect the building’s history, including Hattie’s Parlour and the Banker’s Boardroom, while a 24-hour fitness center and an on-site coffee counter round out the daily guest amenities.
- The Treasury Cocktail Lounge: Ground-floor lounge and dining space serving house-crafted cocktails, wine, local South Dakota beers, and shareable small plates beneath the historic lobby ceilings.
- The Stronghold Vault: Preserved 1918 steel bank vault featuring its original massive circular door, converted into an atmospheric seating enclave off the main lounge.
- 90 Custom Rooms & Luxury Suites: Distinctive accommodations spanning floors two through nine, ranging from Deluxe King rooms to Whirlpool and multi-room Presidential Suites.
- Hattie’s Parlour & Banker’s Boardroom: Dedicated private event and executive meeting spaces tailored for small corporate gatherings, bridal showers, and private dinners.
- Heated Underground Valet Parking: Full-service valet parking that stores guest vehicles in a climate-controlled subterranean garage, an essential convenience during South Dakota winters.
