Sixth and Guadalupe is an under construction 66-story mixed-use skyscraper in Downtown Austin, Texas. On November 2, 2022, the building celebrated its topping out, making it the tallest building in Austin, surpassing The Independent^[1], and the sixth tallest building in Texas. The tower is expected to be completed and delivered in summer 2024.^[2]

In 1925 a red-brick five-story hotel called the Alamo Hotel was built on the site. For a time this hotel was the home of Sam Houston Johnson, younger brother to President Lyndon B. Johnson.^[3] The Alamo Hotel was also featured, briefly, in the music videos for Rock the Casbah and Pancho and Lefty.^[4][5] and was a former stomping ground of actor Harry Anderson.^[6] In 1984 the Alamo Hotel was torn down to make way for a 27-story mixed use office-hotel complex called Lamar Financial Plaza which, if built, would have been the second tallest building in Austin at the time.^[7][8][9] However, those plans were scrapped amidst the savings and loan crisis.^[10]

In 1998, the former site of the Alamo Hotel was replaced with a 97-room Extended Stay America, amid controversy.^[11] In 2019, the Extended Stay America was torn down and ground broke on the current building.^[1] On December 31, 2021, Meta signed a lease to occupy all eighteen floors of leasable office space,^[12] however, on November 3, 2022, a Meta spokesperson said that in light of declining profits, Meta would instead sublease the office space it had signed a lease for.^[13] On April 5, 2023, it was revealed that Kimbal Musk had signed a lease to open up a restaurant in Sixth and Guadalupe.^[14]

Floors two through 12 contain 1,626 parking spots and 50 electric car charging stations, floors 14 through 32 contain 589,000 square feet (54,700 m²) square feet of office space and floors 34 through 66 contain a 349-unit apartment complex, Residences at 6G.^[15][16]

The building's unique angled shape is due to Texas Capitol View Corridors^[17][18] (#8, South Lamar at La Casa Drive).^[19]
