From 1820 to 1830 he was again, under his qualification, employed as Country master builder in the fourth building district at the Royal Government in Potsdam and was an employee of Karl Friedrich Schinkel.
From December 8, 1820, Sachs was appointed to the examination commission for building craftsmen, and his area of responsibility here was the district of Spandau.
At this time he lived at Spandauerstraße 49 in the center of Berlin.
On December 3, 1824, a so-called art road from Prenzlauer Tor to Heinersdorf was approved, it is today's Prenzlauer Allee.
Sachs had done all the preliminary work here, including surveying, design, situation plan and cost planning.
He brought together the most distinguished residents, who enabled him to do the necessary work financially.
This group formed a public limited company, which, with the help of the government, put the project into practice.
In 1825 Sachs began planning the new construction of the Fasanenmeisterhaus in the Tiergarten in its improved loam construction.
The commission was given by the royal chief hunter Friedrich Detlev Graf von Moltke. (
1750–1825).
According to an expert opinion, issued by Friedrich Schinkel and Johann Carl Ludwig Schmid, on his [[rammed earth] pisé] buildings, which was devastating for Sachs, he was unable to complete his work.
Schinkel was commissioned by the Oberbaudeputat to execute the house in classical brick construction.


The animosity of the members of the Oberbaudeputation against Salomo Sachs increased further.


After Sachs was crushed by the Oberbaudepartement with his plans for the new home of the pheasant hunter, he was commissioned by Wilhelm zu Sayn-Wittgenstein-Hohenstein to hand over his drawings and cost accounting, for comparison with Schinkel's designs.
After the handover, his work disappeared forever, despite demands for restitution, and Sachs was not paid for his expenses until 17 years later.
Despite these setbacks and insinuations, he continued to work on his reputation.
In 1829 he was commissioned by the sons of Otto von Voß to Birkholz (Bernau near Berlin) to design and rebuild a new church tower.
At the same time Carl Justus Heckmann for the roofing and Carl August Mencke for the gilding of the spire were also appointed to the building work.
From 1829 to 1830, Sachs became increasingly disliked by the royal government and his superiors.
He had been commissioned by the military, who were convinced of his cost-saving clay construction method, to build a cavalry horse stable in Charlottenburg.
At the request of the military leadership, the construction was to take place very quickly and under his sole leadership without the participation of the royal government.
This caused further tensions with his superiors, as the design in brick was already available.
