A high-rise under construction in downtown San Antonio since early 2022 is almost complete and the first residents now have 300 Main Ave. as their new address.
With only the top few floors in need of a finishing touch, more than two dozen residents have already moved into the 354-unit high-rise at North Main Avenue and East Travis Street known as 300 Main.
Built by developer Weston Urban with Rogers-O’Brien Construction, 300 Main spans an entire city block and, at 32 stories, easily beats out San Antonio’s urban office and hotel towers as one of the tallest buildings on the skyline. The estimated cost of construction is $107 million.
For the unparalleled views, spacious floorplans and amenities galore in the city’s newest luxury residential tower, 300 Main is also demanding some of the highest rental rates in San Antonio, where the average monthly rent is $1,282.

Members of the Weston Urban development team who oversaw the project for over two years led a tour of the building with the leasing manager Thursday afternoon.
Though the project broke ground just before interest rates began to climb in recent years, rising construction costs put pressure on the developer.
Weston Urban is also building the Continental block, a 16-story residential project at West Commerce and Dolorosa Street, and is in talks with the city to redevelop the northwestern quadrant of downtown where a new baseball stadium has been proposed.
“There are multiple times in every project where you get a little pessimistic and you can’t do development without having just an unrealistic sense of optimism,” said Mark Jensen, vice president of multifamily at Weston Urban. “We’re going to figure this out, figure out some way around, try to make it happen.”
The work of local artists dominates the decor of the tasteful main lobby and hallways at 300 Main. A smiling portrait of Texas statesman and revolutionary José Antonio Navarro by Lionel Sosa hangs over the reception desk and a grand mosaic sculpture by Oscar Alvarado serves to separate spaces within the large entrance hall. The interiors were designed by Austin-based architecture firm Page.
An acre of amenities and common spaces were built into 300 Main on floors 7 and 25, with a large fully equipped fitness center and outdoor workout space, furnished resident lounges and coworking spaces and pods, and a television and game room.

On outdoor decks, there are hammocks, more shaded lounge areas, a swimming pool with five cabanas, and kitchens with grills and even a pizza oven.
Planters in these common areas were designed and landscaped by Austin-based Cameron Campbell’s Architecture with native plants, grasses and at least one bald cypress tree.
The property also provides residents with a hospitality suite that can be rented nightly for guests.
Most of the units at 300 Main feature 10-foot ceiling heights, expansive windows and in-unit laundry; all have modern kitchens and some also offer built-in desk units.
There are 22 floor plans to choose from in studio, one-, two- and three-bedroom apartments in varying sizes. A studio apartment starts at $1,432 and a one-bedroom, $1,637, said Josie Johnson, general manager with Kairoi Residential.
On the top two floors, there are 10 penthouse units with monthly rent starting at $6,000. A 1,776-square-foot penthouse apartment with two bedrooms and a den, panoramic views and a patio rents for $10,300 a month.

The residential part of the building sits on top of a multilevel parking garage with 456 vehicle spaces, about a third of which are reserved for residents and the remainder for the general public.
At street level, 300 Main has 3,500 square feet of retail space for lease, including a space designed to serve as a restaurant with windows and a patio facing Travis Street.
Though rivaling its height, 300 Main contrasts sharply with its neighbor Frost Tower, the 24-story, sleek office building of reflective glass built by Weston Urban in 2019.
“We really wanted this structure to blend with the whole city, but to also be different and a little striking from different angles,” Jensen said. One corner of the building is glass while other parts of the facade are covered in brick and other material.
“We tried to design 300 Main so that wherever you are approaching it from the city … it would look slightly different, instead of being one monolithic structure with the same kind of window layout,” Jensen added.

Situated between the historic Milam Building, also owned by Weston Urban, and the Robert E. Lee apartment building, which the developer has offered to buy, the block where 300 Main was built was once a parking lot.
“We want to activate more land and more surface parking and turn that into housing and active use to bring life into downtown,” said David Robinson Jr., development manager at Weston Urban.
