Overview

St. John Properties, in partnership with the U.S. Army, is developing The Government and Technology Enterprise (The GATE), a business park built for government contractors and federal agencies. The offering includes office and flex space designed to support both technology-oriented operations and general business use.

The project is positioned for unmatched proximity to federal customers of APG. Parking is planned at approximately 4–5 spaces per 1,000 square feet. Ceiling height is designed to match the use mix, with flex areas at approximately 16–18 feet and office areas at approximately 10 feet.

For tenants seeking a facility purpose-built for government-related work, The GATE provides the physical mix of office and higher-clearance flex space, along with parking parameters established for the project. This configuration supports day-to-day office functions while accommodating space needs that benefit from greater ceiling height in the flex areas.
