Best refurbished building

The Betonsilo is a prominent feature of the striking Plange Mühle industrial architecture, which dates back to 1906. Since 2001, the entire area has undergone renovations and redevelopment in phases – always in close collaboration with the heritage preservation authorities. 

The abandoned piece of industrial architecture awakens to a new purpose. Once a utilitarian storage of grain, the curved shell transforms into an intimate and welcoming place, accommodating two clinics and various healthcare facilities. The arrayed compartments provide harmonious and functional working spaces as well as ambient and serene ward retreats.

Today, the Betonsilo is a vivid part of the thriving Plange Mühle campus, embodying the spirit of the present while honoring the past. Its reinvention is a testament to the potential of existing structures, its low carbon footprint - a reminder of the power of preservation.

The Lanserhof Sylt resort blends harmoniously with the stunning island landscape and exudes a magical atmosphere, immediately felt by anyone who arrives. It is a sanctuary designed to harmonize with the environment, a tranquil and healthy place.

Natural materials and the minimalistic interior create a calming ambiance amidst the wilderness of the rough seaside. Wind protected loggias in the thatched roof provide a private outdoor retreat for each room. The mesmerizing, spiralled staircase in the heart of the building connects all levels and is simultaneously a piece of art to enjoy. 

A plunge in the saltwater pool, a breath of fresh air, the warmth of the fireplace – the Lanserhof Sylt gathers all elements for a holistic recovery in peaceful seclusion.

The Kö-Bogen II Ensemble was honoured with the DGNB Diamond award for its remarkable and ambitious architecture. This rare recognition is a complement to the DGNB Platinum certification, which the Kö-Bogen II achieved with the highest sustainability fulfillment level ever attained for a commercial building. The decision was made unanimously by the DGNB appointed design commission of three renowned architects and critics.

The mixed-use retail and office building reaches iconic quality through the experiment of its green façade. The addition of this new structure to the existing post-war architecture creates a captivating fusion of eras and uses, resulting into a place with undeniable allure. Each façade is tailored to its respective surroundings, adapting both shape and proportion, thus seamlessly blending into the urban fabric. The publicly accessible lawn on the pavilion building’s roof expands the versatile open space of the Gustaf-Gründgens-Platz.
