300 Wyandotte is a River Market office building in Kansas City, Missouri, best known as the purpose-built headquarters associated with HOK Sport, the sports-venue practice later known as Populous. The property is now identified as 3Y, and Sporting Kansas City lists its front office at 300 Wyandotte Street, Suite 300. It is an office property rather than a public attraction, museum or sports venue.
The building’s history is easiest to understand as a sequence of identities: an office headquarters completed around 2005, a former Populous workplace after the company’s move, a 2016 rebranding as 3Y, and a building that gained new office tenants—including Sporting Kansas City’s front office in 2024. Records disagree slightly on the completion year, so the responsible description is “built or completed in 2005,” with the Downtown Council’s 2024 inventory listing 2006.

300 Wyandotte is a large office building in Kansas City’s River Market district. An ORIX Realty Investment eXchange offering identifies it as the “HOK Sport + Venue + Event Headquarters Building,” places it at Unit 2 of 300 Wyandotte, Kansas City, Missouri 64105, and reports 94,846 square feet of rentable building area.
That figure is a property description, not a measurement of currently occupied space. It indicates the scale of the office asset described in the offering. The building is also commonly referred to as 3Y, the name adopted after a later ownership change and rebranding. “300 Wyandotte,” “3Y,” and the former HOK Sport headquarters therefore describe the same River Market office property at different points in its history.

For current wayfinding, Sporting Kansas City’s official contact page lists the club’s front office as 300 Wyandotte Street, Suite 300, Kansas City, MO 64105. That listing identifies a tenant’s office address; it does not establish that every part of the building is open to visitors.
Why is 300 Wyandotte associated with HOK Sport and Populous?
The building was developed as the headquarters for HOK Sport + Venue + Event, the sports and entertainment design practice associated with HOK. The practice later became known as Populous. Sporting Kansas City’s account of its office space says the building was built in 2005 for Populous, while the ORIX profile uses the longer HOK Sport + Venue + Event Headquarters Building name.

HOK Sport’s later Populous identity explains why older property material, local reporting and current tenant information can appear to use different names for 300 Wyandotte. It is more accurate to say that the building was created for the HOK Sport practice and later associated with Populous than to treat HOK Sport and Populous as unrelated occupants.
The available records do not identify the building’s architect, construction contractor, structural system, or material specifications. The company history establishes the headquarters connection, but it is not evidence for attributing design or construction work to a particular firm.
When was 300 Wyandotte built?
Most direct descriptions give 2005 as the construction or completion year. The ORIX investment profile says the office property was completed in 2005, and Sporting Kansas City likewise says it was built in 2005 for Populous. A separate public record uses a different convention: the Downtown Council of Kansas City’s 2024 development report lists the 3 Wyandotte Building at 300 Wyandotte as completed in 2006.

The sources do not explain whether the difference reflects a certificate-of-occupancy date, a project-completion convention, or another classification. Do not turn the discrepancy into a false precision. In a general history, “built in 2005” is the best-supported primary description; a property inventory may list 2006.

| Sporting Kansas City | Built in 2005 for Populous | Tenant description of the 3Y office and its visible features. |

What does the building look like?
The clearest published physical description comes from Sporting Kansas City. Its account highlights floor-to-ceiling glass windows and a rooftop patio—features that help explain why the property has been presented as a distinctive office environment rather than a conventional enclosed commercial block.
The building is reported at 94,846 rentable square feet, but the available sources do not provide a verified floor count, site area, structural system, energy rating, façade specification, or renovation history. Floor-to-ceiling glass is a descriptive feature, not proof of a particular curtain-wall system or performance standard. Likewise, a rooftop patio confirms an amenity reported by a tenant source; it does not establish public rooftop access.
Because the available sources do not verify an architect or contractor, construction readers should resist filling those gaps with assumptions based on the building’s appearance. A glass façade can be delivered through many structural and enclosure approaches, and the public sources do not identify which one was used here.
What happened after Populous left?
Populous had left the property by 2015, according to Flatland KC’s reporting. The following year, Somera Road purchased the property in August 2016 and rebranded it 3Y. That change explains the building’s modern shorthand: a site originally marketed through its HOK Sport connection became the 3Y building in later commercial and tenant references.

Flatland KC reported in 2019 that WSP opened a 42-person office at 3Y. The report documents that office as one tenant and should not be read as a complete tenant roster. Commercial buildings can have several occupants, and the available sources do not establish that Populous, WSP or Sporting Kansas City were ever the only users.
Sporting Kansas City says it moved into new front-office space at 3Y in 2024. The club’s current contact listing places that office in Suite 300. This is a later phase of the property’s office history, not evidence that the building changed into a stadium, event venue or public sports facility.
How did Sporting Kansas City become connected to 300 Wyandotte?
Sporting Kansas City’s connection is a tenant relationship. The club’s published description of its office identifies the building as 3Y, recalls that it was built in 2005 for Populous, and describes the move into new front-office space in 2024. Its contact page supplies the practical address: 300 Wyandotte Street, Suite 300, Kansas City, MO 64105.
That address can be useful when contacting the club, sending correspondence or distinguishing the front office from Sporting Kansas City’s match-day facilities. It should not be used to imply that 300 Wyandotte is the club’s stadium or that the entire property is operated by the club. The sources establish a front-office presence, not ownership of the building or control of all suites.

Which source should you use for each fact?
No single source provides a complete, current property file. Each document has a different purpose, so the most reliable account uses them together without flattening their differences.
- Property identity and scale: The ORIX investment offering is the clearest source for the former headquarters name, River Market location and 94,846-square-foot rentable area.
- Visible features and the 3Y identity: Sporting Kansas City’s office article supplies the floor-to-ceiling glass, rooftop patio and “built in 2005 for Populous” description.
- Current club address: Sporting Kansas City’s contact page is the appropriate source for the front-office suite and mailing address.
- Post-Populous history: Flatland KC provides the reported 2015 departure, 2016 purchase and rebranding, and 2019 WSP office opening.
- Completion-year comparison: The Downtown Council’s 2024 data sheet is the source for the 2006 listing.
- Commercial listing corroboration: A LoopNet profile can help confirm the 3Y listing context, but commercial listing details can change and should not override dated historical reporting.
This source-by-source approach matters because an investment offering, a tenant article, a city-center inventory and a retrospective news report answer different questions. It also prevents a current tenant address from being mistaken for a complete ownership or occupancy record.
Is 300 Wyandotte a public attraction?
The available evidence does not establish public visitor access. 300 Wyandotte is documented as an office property, and the rooftop patio and glass windows are reported workplace features—not advertised visitor amenities. Anyone seeking a meeting, tour or delivery should arrange it with the relevant tenant rather than assuming that the lobby, rooftop or suites are open for walk-in access.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should construction and property readers avoid assuming?
Several tempting conclusions are not supported by the documented record. First, the 94,846-square-foot figure is rentable building area from an investment profile; it is not a current occupancy measurement. Second, the 2005 and 2006 dates should be reported as a discrepancy, not blended into an invented exact completion date. Third, the HOK Sport and Populous names identify the headquarters connection and later corporate identity, but they do not identify the architect, general contractor or current owner.

Similarly, the presence of WSP and Sporting Kansas City demonstrates documented tenancy at particular times, not a full tenant list. The LoopNet listing and other commercial pages may change as suites are marketed. For a title search, lease question, permit investigation or construction record, readers would need authoritative municipal or ownership documents beyond the sources summarized here.
How should you describe 300 Wyandotte in one sentence?
A precise short description is: “300 Wyandotte is a River Market office building in Kansas City, Missouri, built or completed around 2005 as the HOK Sport + Venue + Event headquarters, later rebranded 3Y, and now home to offices including Sporting Kansas City’s front office.” This wording preserves the documented history, acknowledges the naming change and avoids claiming public access, current ownership or an unverified design credit.

Frequently Asked Questions
What is the 3Y building in Kansas City?
3Y is the later identity of the office property at 300 Wyandotte in the River Market. Somera Road purchased the property in August 2016 and rebranded it 3Y, after the former Populous occupant had left.
Is HOK Sport still located at 300 Wyandotte?
The available reporting says Populous had left the building by 2015. HOK Sport’s historical headquarters connection explains the property’s original name, but the sources do not show that the company remains a tenant.
Can I tour the former HOK Sport headquarters?
No public tour or visitor program is documented in the available sources. Contact the specific tenant before going, because an office address and rooftop patio do not imply walk-in access.
Who owns 300 Wyandotte today?
The reviewed sources identify Somera Road’s 2016 purchase, but they do not establish the property’s current owner. A current ownership answer would require a recent authoritative property or county record.
Does Sporting Kansas City own the 3Y building?
Sporting Kansas City is documented as a front-office tenant in Suite 300 after moving there in 2024. The published address does not indicate that the club owns the building or controls its other suites.
