St. John Properties, Inc. plans to break ground early next spring on a 120,000-square-foot project in Leander that will become the suburban community’s first Class-A office building and the first commercial component of the 116-acre urban, mixed-use Northline development 30 miles from Austin.

The four-story building is designed to earn LEED certification and will offer high-quality finishes, floor-to-ceiling windows, as well as 15,500 square feet of ground floor retail and restaurant space. The floorplates will be able to accommodate tenants that are diverse in size and services. Located at 1157 Main St., the project is scheduled to be completed in the first half of 2025. Perennially listed among the fastest growing cities in the nation, Leander has experienced tremendous residential growth over the last decade, fueling demand for commercial space among retailers and other businesses.

Founded in 1971, St. John Properties is one of the nation’s largest and most successful privately held commercial real estate firms with assets of more than $5 billion across 11 states. The Baltimore-based developer opened a Texas regional office in Austin in 2022.

St. John Properties specializes in multi-tenant buildings designed to serve tenants small to large such as law firms, tech companies and business consultants. Suites offered in the new Northline building will start at 2,000 square feet.

The company frequently builds in suburban areas to be near the residences of business owners, and the Northline project will match the company’s approach to construct office buildings in a walkable, mixed use suburban development.

The start of construction on the new office building will mark a major milestone for Northline, Leander’s new downtown district is slated to include more than five million square feet of office, retail, residential, hotel and civic space as well as a signature park.

Residents will begin moving into Northline’s first apartments and townhomes later this year.

The project also serves as a breakthrough for Leander, which has prioritized attracting more employers and retailers to the community in order to diversify its tax base and provide more employment opportunities to residents closer to home.
