The historic Burgmühle [castle mill] with a granary in Brandenburg an der Havel can look back on 700 years of tradition. In 2002, it was almost completely destroyed by fire and collapsed in places. In the course of the renovation, 64 high-quality condominiums and two commercial units in a prime waterside location were created.

Listed buildings require high-quality building materials

Bernd Jansen, managing director of Jansen Immobilien GmbH, was responsible for the restoration project. “The strict regulations for listed buildings required the preservation of the character of the industrial monument on the Dominsel, the Cathedral Island." The investor decided in favour of systems supplier Wienerberger, whose high-quality building materials are suited for conservation projects and also satisfy the requirements for multi-storey residential construction in terms of soundproofing, thermal insulation and fire protection.

Town centre charm with river view

Because large parts of the façade survived the fire, it did not require complete rebuilding. When complementing the existing brickwork, it was important from a building physics point of view to select a similar ceramic building material to avoid a mixed construction method. Damaged facing bricks in the façade were cut out by hand and replaced with colour-matched smooth extruded bricks from Wienerberger: Schleswig ruby red and Heide red shaded.
 
For the inner layer 365mm clay blocks were used. This all-ceramic clay block comes closest to the existing brickwork in terms of sustainability characteristics. Due to the high standards of sound insulation required for the internal walls, sound-insulating blocks were used as well as clay block composite floors, which are suitable for properties of this kind. For the gables, the client decided on thermal insulation blocks filled with mineral wool. Another advantage of this block is that it saves space due to its slimmer dimensions. The monolithic integrated construction following the reconstruction guarantees the owners a good investment, a healthy room climate and all the benefits of sustainable construction.
 
Now restored to a high standard, the Burgmühle has become a fascinating architectural eyecatcher. A building where grain was once processed has become a place for modern forms of living and working.
