Renderings for a proposed building at 600 Guadalupe Street downtown reveal a planned design that’s both fairly distinctive and dauntingly tall. 6th + Guadalupe, as it’s called, is being developed by Lincoln Property Company along with partner Kairoi Residential and is planned for mixed office and residential use.

Renderings by Gensler, the architecture firm for the project, were submitted along with a proposal to increase the building’s density (floor-to-area ratio, or FAR) and other materials to the Austin Design Commission for last Thursday’s meeting, which was canceled due to a lack of quorum. The developers propose increasing the FAR in part of the building from 8:1 to 25:1, paying more that $2 million into the city’s affordable housing trust fund in lieu of providing onsite affordable housing in order to qualify for the city’s downtown density bonus—a fairly common practice.

The proposed building would consist of two stacked towers, with 349 residential units above 575,000 square feet of offices. That, along with other unusual features, will create a relatively distinctive profile in the Austin skyline. Adding to the distinction is that it is planned to be 837 feet high, making the 66-story building the tallest in Austin.

According to a Wednesday Austin Business Journal article, the plans submitted had been revised after involved parties met in a design committee workshop. A historic house at the corner of 7th Street and Guadalupe will be preserved and built around, and ground-floor restaurant and retail space will be added to unify and activate the streetscape. The newer plans also have a revised design for the wall facing the historic house to work better with its scale.

According to the Journal, developers are continuing to work toward compliance with all the city’s requirements and expect site-plan approval in the next 30 days.
