The city planning director Bernhard Matthias Brasch, who had been active in the city since 1783. (1741-1821) implemented the specifications of the reconstruction commission and supervised the corresponding works. These took place from 1788 to 1803, following a uniformly planned ground plan.Ulrich Reinisch: The Reconstruction of the City of Neuruppin after the Great Fire of 1787 or: how the Prussian bureaucracy built a city. Reconstructed and explained according to the files = Forschungen und Beiträge zur Denkmalpflege im Land Brandenburg 3. Wernersche Verlagsgesellschaft, Worms 2001. ISBN 978-3-88462-173-8 Brasch's plan envisaged the expansion of the city from 46 to almost 61 hectares with the removal of the ramparts between the Tempelgarten and the lake. The two north–south streets, which were close together, were united into one axis, later Karl-Marx-Strasse. A rectangular network of streets with continuous two-story troughshouses was created. Long wide streets interrupted by stately plazas, and houses in a transformation architecture mixing Baroque, Mannerist and Gothic design elements with Neoclassical trends, have shaped the townscape since that time. These urban reform principles are well recognizable. Thus, with the reconstruction, a classicist city layout unique in this originality was created. The reconstruction was already completed in 1803. Only the completion of the parish church of St. Mary (built 1801-1806 by Philipp Bernard François Berson with the collaboration of Carl Ludwig Engel) dragged on until 1806 due to structural problems.
