About this workspace
Onyx Building sits within Park 7 in Diegem, between Brussels Airport and central Brussels. This green campus hosts modern offices alongside daily services that make work straightforward. As a result, teams gain a practical address with quick access to clients, suppliers, and amenities. Plus, nearby international companies and service providers create useful connections for day‑to‑day operations.
Inside, private offices, coworking areas, and bookable meeting rooms come ready with high-speed Wi‑Fi and ergonomic furniture. In addition, breakout areas, stocked kitchens, and an on-site team support day‑to‑day operations. Showers, secure bike storage, and recycling facilities encourage low‑impact commutes, while the building’s near–CO2‑neutral design underlines its sustainability. For focus or collaboration, rooms include screens, video conferencing, and secure access systems.
Diegem railway station sits a short walk away, with frequent trains into Brussels and the wider region. Meanwhile, local bus routes and the R0 ring road link the campus to surrounding districts and the A201 for the airport. Drivers benefit from on‑site or nearby parking, making arrivals predictable for visitors and teams.
The area offers hotels, cafés, and restaurants suited to client meetings or post‑work plans, with green spaces close by. In addition, nearby hotels and the airport expand meeting and travel options. However, the campus setting keeps things calm during the day, even when schedules are busy. Onyx Building offers a well-connected base for teams in Diegem.
