Brussels Office Districts: The Complete Guide

The Pentagon takes its name from the pentagon-shaped inner ring road that outlines Brussels' historic city centre. It is the capital's second-largest office market, even though the city centre also serves retail, residential and leisure functions. Office clusters are concentrated near the pedestrian zone and Brussels-Central station, in an environment hosting many major public-sector, financial and services occupiers.

The district benefits from three main railway stations and an excellent public transport network. Sub-areas such as the Marolles or Mont des Arts add to its vibrancy, with a dense offer of restaurants and shops.

The Louise district is centred on Avenue Louise, one of Brussels' most prestigious avenues, linking the city centre to the Bois de la Cambre through the municipality of Ixelles. A very lively area, it blends office buildings, housing, shops, restaurants and hotels, with a strong concentration of law firms, consultancies and financial institutions drawn by the prestige of the address.

Accessibility is excellent: the inner ring road provides easy access by car, while Louise metro station, the tram (Place Stéphanie and Defacqz stops) and several bus lines serve the district. Its central position also makes it accessible by bike. The district hosts everything from small companies sharing coworking spaces to large corporates occupying an entire building.

The district benefits from a particularly resilient letting market: prime rents rose by 20% year-on-year according to JLL Research data, while remaining stable elsewhere in the capital.

The European Quarter, also called the Leopold Quarter, is Brussels' largest office district: around 3.3 million sqm, or 25% of the Brussels market. Close to 40% of this stock is occupied by the EU institutions, alongside numerous national representations, lobby groups and international companies located around Place du Luxembourg.

Bounded from west to east by the inner ring road, from Place Madou to Tour Bastion, the district benefits from an excellent transport network (Schuman station, Rue Belliard, Rue de la Loi) reaching Brussels Airport in twenty minutes. The atmosphere is international, with numerous green spaces and a dense dining offer around Place du Luxembourg.

The district is the subject of a redevelopment project led by the Brussels Region (source: perspective.brussels — European Quarter Vision). Leasing activity remains strong: in 2025, EU institutions alone accounted for 61,000 sqm of take-up in Brussels, with several major deals in this district (The Loom, EQ, Monterra).

The Midi District | Station Hub/Mobility

The Midi district (or Midi-Lemonnier) brings together office buildings around Brussels-South station, the country's main railway station and the Eurostar and Thalys terminus. Buildings here are mostly modern, built since the early 2000s, and host federal administrations as well as large international companies.

Several redevelopment projects are underway, including a new office tower and a mixed-use zone, alongside new transport infrastructure such as STIB's future metro line 3.

🔍 JLL EXPERT ANALYSIS

"The real story lies elsewhere": according to Pierre-Paul Verelst, Head of Research BeLux at JLL, the real fault line in the Brussels office market runs between the city centre and its periphery. By late 2025, vacancy in the Central Business District (Pentagon, North District, European Quarter, Louise, Midi) held steady at around 4%, driven by the scarcity of new-build stock, while it stood at around 19% outside the CBD — and could approach a quarter of stock in the airport district as new deliveries arrive.

The Decentralized area accounts for close to a fifth of the Brussels office stock, spread across several clusters offering a capital-city address at rents representing only 50% to 60% of European Quarter levels. It hosts Belgian companies from every sector — banking and finance, business services, technology — as well as certain decentralized EU services.

Public transport accessibility can be excellent in some spots, but it varies significantly from one sub-area to another. According to the Brussels Region's Office Observatory, vacancy structurally remains higher in these second-ring zones than in the city centre (source: perspective.brussels).

The North District, Brussels' second-largest business district after the European Quarter, is ideal for companies wanting to stay close to city-centre amenities while benefiting from contemporary architecture. Well served thanks to its proximity to Brussels-North station, it blends large office towers with SMEs.

The district splits into three distinct office sub-areas. Espace Nord, nicknamed Brussels' "mini Manhattan", is home to major towers such as the Proximus Towers and World Trade Center III, now largely renovated for mixed use. The Botanique area offers spacious office buildings, a well-known park and a prime position along the inner ring road. The Canal area, finally, is seeing its former industrial buildings replaced by sustainable offices and new concepts combining offices and housing.

This is the district that has seen the strongest growth in its office stock in recent years, driven by projects such as Moebius, Iris Tower, Gare Maritime and the Quatuor complex — despite the demolition of the former WTC I and II towers (source: JLL Immo — full article on the North District).

The Southern Periphery | Walloon periphery

The Southern periphery covers the Walloon municipalities of Waterloo, Wavre, La Hulpe, Braine-l'Alleud, Louvain-la-Neuve and Mont-Saint-Guibert, plus the neighbouring Flemish municipality of Hoeilaart. These locations share common strengths: proximity to major motorways, a green setting and comparatively lighter property taxation.

This zone is an excellent option for satellite offices, particularly for companies seeking a different, greener and more affordable working environment than the city centre.

Offices in the North-Eastern periphery are mainly located in Zaventem, Machelen, Vilvoorde and Sint-Stevens-Woluwe. This zone benefits from its immediate proximity to Brussels Airport and the Brussels ring road, an extensive green setting and lighter land taxation, specific to the Flemish Region.

Historically popular with tech and business-services SMEs, the zone is now also attracting large multinationals thanks to the recent arrival of high-quality office buildings near the airport terminal.

The North-Western periphery is mainly located around Vilvoorde, a short walk from the railway station serving the Brussels–Antwerp lines, with quick access to Brucargo and Brussels Airport. This zone combines good multimodal accessibility with occupancy costs more competitive than the city centre.
