1697
Construction of the new office building (today's Rössle). The foreman was Bartholomäus Kraz, who was assisted by Tyrolean bricklayers. The expenditure for the timber-framed building on the upper floors totalled 1382 guilders and 9 kreuzer (approximately EUR 50,000 in today's money). The bailiff at the time was Paul Ötschmann, born in Heining, Tyrol. He was a fresco painter and created frescoes for the Duke of Württemberg in Stetten Castle in the Rems Valley and the ceiling paintings in the imperial hall of Wettenhausen Abbey. His detailed epitaph on the church tower of Aufheim does not mention his artistic activities. The Amthaus had also preserved a fresco with the coat of arms of the Wiblingen prelate Modest I. Huber until 1969 (north-east corner room on the upper floor).
