Twin squares was conceived to provide a green, natural working environment, an oasis of calm in the midst of one of the busiest business districts serving the capital of Europe. Trees and planted

areas are all around, there is a lake, a wooden bridge giving access to the restaurant. Everything, in fact, is designed to ensure optimal conditions in which to work. The buildings themselves are equipped with the latest technology. High performance air conditioning, make use of economical

techniques, raised floors… And to add to both to the efficiency and to the environmental credentials of Twin Squares, a night time tariff applies to heating and cooling, reducing energy costs.

A high degree of façade insulation also reduces energy needs. These are two buildings which can be classified as “comfortable”. There is ample private car parking for the entire site, a high quality

restaurant, meeting rooms and a business center on the site.

Location and Transport

The offices in the North-East periphery are mainly located in the municipalities of Zaventem, Machelen, Vilvoorde and Sint Stevens-Woluwe. They benefit from the proximity of Brussels Airport, the Brussels Ring Road, an extensive green environment and lower property taxes applicable in the Flemish Region.

Originally, the area attracted small and medium-sized companies in the technology and business services sector. Although this is still the case, the recent addition of large office buildings in the Brussels Airport terminal area has attracted large multinationals from different sectors.

The airport sub-district benefits from excellent national and international travel connections, shopping malls and hotels, as well as future expansion possibilities on the site.
