A 120,000-square-foot office building is slated to be be the first commercial component to get going in Northline, a planned 116-acre mixed-use headed for a booming Austin suburb Leander. The four-story building at 1157 Main Street will include 15,500 square feet of ground-floor space for retail and restaurant tenants of varying size. Baltimore-based developer St. John Properties plans to break ground to break ground on the project in the first quarter of 2024.

The building will be designed for a variety of business tenants, including law firms, tech companies, and consultant firms, according to St. Johns. Suite sizes will start at 2,000 square feet.

Northline, which developers are calling "Leander’s new downtown district," is a planned community underway in Leander’s Transit-Oriented Development (TOD) core.  Its name is derived from its location at the northern end of Capital Metrorail's Red Line, which runs from downtown Austin. It's planned to include more than 5 million square feet of office, retail, residential, hotel, and civic space as well as a park. Residents will begin moving into Northline’s first apartments and townhomes later this year.

The project team for the St. John Properties Northline office building includes: architecture firm Beck Design, civil engineers Kimley-Horn, MEP design by WGI, structural engineers Dunaway, and KW Landscape Architects. The office development is scheduled to be completed in the first half of 2025.
