Overview
Located in the heart of Downtown Sioux City’s entertainment district, the property benefits from an urban office setting where tenants can reach surrounding retail and entertainment demand. The building also allows for strategic expansion within the condominium portfolio.
For an owner-user, the asset’s purpose-built security background can be valuable for organizations that require a more controlled office environment. For investors or multi-user operators, the ability to lease 3,478 SF and the option to combine with adjacent Units 300/310 (1,987 SF) at the same price per square foot can support a range of occupancy and capital strategies without forcing a single-use commitment.
