T-Mobile Headquarters Building Two – Bellevue

The goal was to celebrate the company's unique brand and culture, focusing on recruiting top talent and employee retention in a competitive job market. Gensler's designers leveraged data from the Gensler Workplace Performance Index survey, interviews, workshops, and analysis to inform campus navigation, programming, space planning, and brand experience, allowing the team to strategize and design to reflect T-Mobile's unique, customer-obsessed culture that focuses on delivering for consumers and businesses in new and innovative ways. T-Mobile's most recently renovated 144,995-square-foot Building 2 is part of a larger campus transformation that reinforces the company's position as an industry disruptor. The design translates T-Mobile's bold, magenta-centric brand identity into spatial terms, using color, graphics, and experiential moments that surprise and energize employees and visitors alike. The workplace is organized around neighborhoods that support different business units while sharing central amenities that encourage cross-team interaction. Open collaboration zones, social staircases, and lounge areas are strategically placed to increase spontaneous encounters. The campus emphasizes transparency and openness, removing hierarchical barriers and creating spaces where employees at all levels can connect. Amenities are extensive and on-brand, including cafes, game rooms, fitness areas, and gathering spaces that reflect T-Mobile's playful yet high-energy culture. The design also supports a hybrid workforce, with a mix of assigned and unassigned workpoints, bookable rooms, and technology that enables seamless collaboration between in-office and remote team members. Data-driven insights guided decisions on space allocation, density, and amenity programming, ensuring the campus responds to actual employee needs. The completed headquarters serves as both a talent magnet and a daily expression of T-Mobile's un-carrier philosophy.
