Discover SQUARE 42 (Projet), an innovative office development currently under construction at Porte de France 1 in the vibrant Belval district. This premium project, spanning over 21,850 m² across seven floors, will be delivered in 2027 and sets new benchmarks for discerning businesses. Available for rent, it offers flexible spaces ranging from 550 m² to full floors exceeding 3,000 m², designed to accommodate every work style. With its wood-concrete hybrid structure and BREEAM Excellent and WELL Gold certifications, this development combines architectural excellence with ecological commitment, creating a workspace that enhances creativity and well-being upon completion.
Situated in the heart of Belval's rapidly evolving district, SQUARE 42 benefits from an exceptional urban ecosystem where business, culture, and leisure coexist seamlessly. Steps from the building, Belval Plaza shopping centre, the Rockhal venue, and diverse dining options create a dynamic atmosphere, while Esch-sur-Alzette – former European Capital of Culture – enriches the area with its cultural heritage. The neighbourhood already attracts global leaders including Deloitte, Société Générale, and RBC Investor Services Bank, forming a thriving innovation hub. This unique synergy of green spaces, prestigious institutions, and premium amenities makes it an ideal destination for talent attraction and collaborative growth.
SQUARE 42 stands out for its exceptional accessibility: connected to Luxembourg City in 20 minutes via Belval-Université station and 15 bus lines (TICE network), with direct access to the A4 motorway for regional travel. Inside, occupants enjoy a wellness-focused design featuring naturally lit spaces, a panoramic rooftop garden, landscaped patios, and premium facilities including a gourmet restaurant and fitness area. Sustainable technologies – rainwater harvesting, photovoltaic panels, and electric vehicle charging stations – position it as a model of ecological transition, perfect for businesses seeking to combine operational excellence with environmental responsibility.
