Completely new buildings such as those in the Hainer Hof were rarely seen as part of the renovation. Mostly, it was a question of reconstructions or additions using traditional technology, which were necessary, in particular, after the cores had been removed to provide facades for the houses in the newly created courtyards. In the case of the half-timbered buildings in particular, however, entire rotten beam layers often had to be completely replaced. A good example of a reconstruction is the restoration of the Renaissance gable at the Haus Klein-Limpurg on the corner of Limpurger Gasse and Römerberg. It was based on illustrations of the building on old engravings, and during the construction work, substance from the Renaissance was actually uncovered, which had been reshaped during the classicist redesign of the building around 1800.
