Executive Summary
Interurban introduces a different category of office ownership in North Texas: individually owned, standalone headquarters buildings for businesses that would rather own their address than rent it. The campus occupies 3.5 acres within Mustang Square, the 36-acre mixed-use district at State Highway 121 and Rasor Boulevard in the Plano–Frisco corridor. Legacy West, The Star, Grandscape, Stonebriar Centre, Toyota, Samsung and AT&T are all minutes away, in one of the densest concentrations of corporate investment and professional talent in the country. Interurban is designed to feel like a district that evolved over time rather than an office park built all at once. Buildings share a single architectural language while varying in form, materiality and detail, so every owner has a distinctive address rather than a suite number. Urban character, suburban freedom. Twelve two-story buildings are available for purchase: Four at 3,500 SF Eight at 3,840 SF There is no standard floor plan. Following execution of the Purchase and Sale Agreement, owners enter a collaborative architectural, engineering and design process that shapes the building around how their company actually operates, covering layout, structural enhancements and finishes. Two adjacent buildings can also be combined into a single headquarters of 7,000 to 7,680 SF. Every building is delivered premium-ready, with a private entrance, two full floors and a private front balcony. A café on site serves the campus. Estimated delivery September 2027. The result is a building that functions as a permanent business asset rather than an expense line.

Description
Building 02 offers a unique 3,840 SF standalone ownership opportunity at Interurban, positioned along one of the most spacious edges of the campus. It is one of only three building sites adjacent to the development’s large easement, creating additional separation and a more open feel than a typical interior site.
That positioning also creates the potential to incorporate a private rear patio or outdoor amenity area into the building design—giving an owner the opportunity to extend the workspace beyond the building itself and create a setting that feels more like a private corporate headquarters.
The two-story building provides approximately 1,920 SF per floor, with 12-foot ceilings on both levels, a front-facing second-floor balcony, and significant flexibility to customize the interior around the needs of the owner. Private offices, conference rooms, executive suites, open workspace, reception areas, collaboration spaces and specialty uses can all be incorporated into the design.
Rather than adapting your business to an existing office, Building 2 provides the opportunity to create a purpose-built, highly customized headquarters with the added benefit of one of the more spacious and uniquely positioned sites within the Interurban campus.
13 dedicated parking spaces, roughly 3.4 per 1,000 SF.
Following execution of the Purchase and Sale Agreement, owners begin a collaborative architectural, engineering and design process to tailor layout and structure around specific operational needs.
Available September 30, 2027.

Building 07 represents one of the last remaining 3,840 SF standalone ownership opportunities at Interurban. Positioned along the western edge of the campus adjacent to Dijon Street, the site benefits from abundant parking surrounding the building and a prominent front position within the development. Its northwestern exposure toward State Highway 121 is interrupted by only a single building, providing excellent positioning within the campus.
Building 07 is also among the closest buildings to Palmera Press, Interurban’s upscale on-site café and coffee shop located within the greater campus.
The two-story building provides approximately 1,920 SF per floor, with 12-foot ceilings on both levels, a front-facing second-floor balcony, and significant flexibility to customize the interior around the needs of the owner. Private offices, conference rooms, executive suites, open workspace, reception areas, collaboration spaces and other specialty uses can all be incorporated into the design.
Unlike purchasing an existing office and adapting your business to someone else’s layout, Building 07 provides the opportunity to create a purpose-built office designed around your company, brand and workflow—within one of the most distinctive new commercial campuses along the State Highway 121 corridor.
13 dedicated parking spaces, roughly 3.4 per 1,000 SF.
Following execution of the Purchase and Sale Agreement, owners begin a collaborative architectural, engineering and design process to tailor layout and structure around specific operational needs.

Description
Building 09 is one of only two 3,500 square foot buildings available at Interurban — the more efficient footprint on the campus, and the entry point into ownership here.
Its position is arguably the best on the site. Along with Building 08, it sits most centered and most directly fronting State Highway 121, one of only four buildings on the campus with direct sign frontage on the corridor.
Approximately 3,500 square feet over two stories, delivered as The Foundry Standard: a fully finished, premium-ready headquarters that carries the same architectural character and design philosophy as the rest of the campus in a tighter, more efficient plan — grand reception and lobby, conference room, executive office, open work area, high-end kitchen with appliances and coffee bar, glass elevator, and a private interior garage.
Combine with Building 08 for a larger custom headquarters across two adjacent buildings — one address, one front door, and the flexibility to program the full footprint around your operation.
12 dedicated parking spaces, roughly 3.4 per 1,000 SF.
Following execution of the Purchase and Sale Agreement, owners may build the standard plan exactly as designed or begin a collaborative architectural, engineering and design process to tailor layout and structure around specific operational needs.

Building 09 is one of only two 3,500 square foot buildings available at Interurban — the more efficient footprint on the campus, and the entry point into ownership here. Its position is arguably the best on the site. Along with Building 08, it sits most centered and most directly fronting State Highway 121, one of only four buildings on the campus with direct sign frontage on the corridor. Approximately 3,500 square feet over two stories, delivered as The Foundry Standard: a fully finished, premium-ready headquarters that carries the same architectural character and design philosophy as the rest of the campus in a tighter, more efficient plan — grand reception and lobby, conference room, executive office, open work area, high-end kitchen with appliances and coffee bar, glass elevator, and a private interior garage. Combine with Building 08 for a larger custom headquarters across two adjacent buildings — one address, one front door, and the flexibility to program the full footprint around your operation. 12 dedicated parking spaces, roughly 3.4 per 1,000 SF. Following execution of the Purchase and Sale Agreement, owners may build the standard plan exactly as designed or begin a collaborative architectural, engineering and design process to tailor layout and structure around specific operational needs. Available September 30, 2027. |

Ownership at Interurban | West Plano extends beyond the individual building. The campus is planned as a walkable boutique office environment on 3.5 acres within Mustang Square, at State Highway 121 and Rasor Boulevard in the Plano–Frisco corridor, centered on the future Foundry Café with hospitality-inspired gathering spaces and planned wellness amenities. Rather than a conventional office park defined by repetition, Interurban is designed to feel like a district that evolved over time — buildings sharing one architectural language while varying in form, materiality and detail. Every owner gets a private building, a front door, and an address that belongs to their business. Minutes from Legacy West, The Star, Grandscape, Stonebriar Centre, Toyota, Samsung and AT&T. |

Building 10 is the second of only two 3,500 square foot buildings at Interurban — the more efficient footprint on the campus, and the most accessible entry into ownership here. It sits directly alongside Building 09, which makes it the campus's cleanest combination: take both and you have exactly 7,000 square feet across two adjacent buildings, one address, one front door, and a full footprint to program around your operation. Approximately 3,500 square feet over two stories, delivered as The Foundry Standard: a fully finished, premium-ready headquarters that carries the same architectural character and design philosophy as the rest of the campus in a tighter, more efficient plan — reception and lobby, conference room, executive office, open work area, high-end kitchen with appliances and coffee bar, glass elevator, and a private interior garage. 12 dedicated parking spaces, roughly 3.4 per 1,000 SF.
