The Duinhotel Tien Torens is a 4-star hotel that is really one with the dunes around it in Zelanda, the Netherlands. It consists of seven accommodations with the characteristic style of Northern European decoration. The hotel especially attracts attention with the marram grass hiding its terraces and interiors, blending the architecture with the landscape. The helm grass also gives the hotel a constantly changing exterior.
The basalt walls of the hotel connect the hotel with the dyke of Zoutelande hidden under the dune. Duinhotel Tien Torens is also a highly sustainable hotel as it generates most of its energy through its solar panels. The position of the sun also has a role in the design. The awning above the terrace prevents overheating during the summer, while the sunlight coming from a lower angle warms the interior during the winter.
