We consider the annex and the main building—including the later addition of the tower—as an ensemble. To bring the annex, which has not been renovated in a while, stylistically closer to the main building, a number of elements can be modified. These include the color of the façade, the plaster texture, the geometry and color of the embrasures, the window colors, the base, etc. Apart from obvious aspects like the color scheme, the treatment of the window embrasures is a central element. The renovation project draws on this theme by deliberately choosing embrasure sizes and colors that match the main building. The substance of the existing openings remains intact; new casings are simply added with a new layer of plaster. In this way, older layers can be uncovered again at a later point if needed. The only reinterpretation of the embrasure theme concerns their top edge, where slightly raised, straight lines replace the segmental arches. This choice serves to align the look with the existing small, orthogonal punch windows on the Annex’s east façade, which are also redesigned. Other than that, the renovation follows the existing structure and materials: the plaster texture and finish are the same, and the beavertail tiles are reused for the roof.
