MAS architectuur designs Rotterdam's Mainport

Design Hotels announced that its new member, Mainport, opened in Rotterdam. The hotel, designed by MAS architectuur is characterized by a futuristic façade of black glass and aluminum; it stands in the central district of Leuvehaven and reflects Rotterdam’s unique architectural aesthetic.

Akin to Rotterdam reflecting international influences and Dutch tradition, Mainport’s overall concept has various cuisines, spa traditions and designs from around the world, while placing an importance on Rotterdam as the hotel’s “main port.” Wellness is a recurring theme throughout the hotel, demonstrated by spa facilities and the hotel’s holistic concept.

Architecturally speaking, Mainport’s step-like facade and windows blend with the hotel’s surroundings. Architect At Tun employed floor to ceiling glass on both sides of the building to create a feeling of connection to the harbor, and also a sense of transparency. Owner Karin Geurts’ vision for the hotel is for it to function as a landing place for travelers and locals alike, thus the open-plan design.

Mainport’s 215 rooms have been split into five categories: City XL, Corner, Waterfront Sauna, Waterfront Spa and the Spa Suite. Each room reflects the hotel’s dedication to wellness by providing an in-room spa with walk-in showers, anti-fog mirrors and a whirlpool. The Waterfront Spa category and the Spa Suite have a private Jacuzzi, Finnish sauna and a mirror integrated TV.


The interiors of the hotel, designed by Feran Thomassen were inspired by different continents. Features include: marble bathrooms, fireplaces and panoramic windows offering views of Rotterdam. Light grey curtains, anthracite desks and dark timber flooring are also available.

In keeping with Mainport’s international influences, the hotel restaurant Down Under and bar on the Rocks are a homage to Australia, in particular Sydney. Located at water level, the restaurant is headed by chef Sander Jongenotter.

Mainport has an eighth floor spa where a Finnish panorama sauna, a Turkish steam room, hamam, two treatment rooms and a relaxation room are available.

Mainport is located in the area of Leuvehaven next to the Maritime Museum and the asymmetric Erasmus Bridge.
