You can read the FAA permit in the PDF, and it seems to indicate that it may violate some protected airspace.

Proposal: To construct and/or operate a(n) Building to a height of 1034 feet above ground level, 1489 feet
above mean sea level.

Location: The structure will be located 5.4 nautical miles northwest of AUS Airport reference point.
Part 77 Obstruction Standard(s) Exceeded:
Section 77.17 (a) (1) by 535 feet - a height more than 499 feet above ground level.
Section 77.17 (a) (2) by 522 feet - a height that exceeds 967 feet above mean sea level within 5.4 nautical miles
of U_AUS.
Preliminary FAA study indicates that the above mentioned structure would:
have no effect on any existing or proposed arrival, departure, or en route visual flight rules (VFR) operations.
have no physical or electromagnetic effect on the operation of air navigation and communications facilities.
have no effect on any airspace and routes used by the military.

Part 77 = Title 14 CFR Part 77, Safe, Efficient Use and Preservation of the Navigable Airspace
Our study has disclosed that this proposed building, located approximately 5.38 nm northwest of the airport
reference point, is within the protected surfaces at Austin-Bergstrom International Airport (AUS), TX.
At the proposed height, these structures will penetrate these protected airport surfaces:
> 77.17 (a)(1) A height of 499 feet AGL at the site of the object.
2021-ASW-4207-OE exceeds by 534 feet.
2021-ASW-4218-OE exceeds by 525 feet.
2021-ASW-4219-OE exceeds by 524 feet.
2021-ASW-4220-OE exceeds by 535 feet.
> 77.17 (a)(2) A height that is 200 feet AGL, or above the established airport elevation, whichever is higher,
within 3 nautical miles of the established reference point of an airport with its longest runway more than 3,200
feet in actual length, and that height increases in the proportion of 100 feet for each additional nautical mile
from the airport up to a maximum of 499 feet.
2021-ASW-4207-OE exceeds by 522 feet.
2021-ASW-4218-OE exceeds by 524 feet.
2021-ASW-4219-OE exceeds by 524 feet.
2021-ASW-4220-OE exceeds by 522 feet.
> The proposed structure would lie within the TPA for CAT D aircraft for descent/climb RWY 18R/36L.
2021-ASW-4207-OE exceeds by 534 feet.
2021-ASW-4218-OE exceeds by 525 feet.
2021-ASW-4219-OE exceeds by 524 feet.
2021-ASW-4220-OE exceeds by 535 feet.
