Challenges
Two objectives guided the design choices.
The reconstruction and redevelopment of the medieval urban environment with façades facing the road along the area’s perimeter, and the realisation of a simple and rational plan with an efficient division of living units looking out on both the city and the inner courtyard.

Setting
The area’s position within the medieval UNESCO heritage urban center dictates the reconstruction of the urban environment with close buildings along the original road perimeter and heights proportioned to the neighbouring buildings. We believe this starter point, emphasised by the city and the UNESCO rules, is the correct one and assume that it is the city’s primary objective from the viewpoint of redeveloping and harmonising the built-up area within the perimeter of the World-Heritage-Site of the historical city.

Volumetric Development
The plan was laid out following the rational logic of a Roman Castra but at the same time it is adapted to the irregular medieval urban structure, summing together the two historical matrices of the city of Regensburg.
Following the perpendicular directrices of the corner building’s two blank façades, two perpendicular directrices tangent to the corner building are the starting points for the masterplan..
The new volumes are set in the space between each of the two directrices and the road, leaving an empty space within the inner area, bounded by a regular and perpendicular perimeter reminiscent and image of the ancient Roman Castra.

Façades facing the road
The design includes road façades with regular pattern of void and fulls with a prevalence of wall surface. Small differences in the position and wideness of the windows are studied in relation to the different views, visual directions, and road sections, to differentiate the façades and create that irregularity and variability typical of the historical centre buil in distinct chronological phases.
