[2] Soller became an influential proponent of Rundbogenstil, a Romanesque revival architectural style that became popular in German-speaking lands and among German diaspora during the 19th century.

To prepare for his master builder's examination, he moved to Berlin and lived with the family of his nephew Richard Lucae.

Soller took over the Department of Churches in the Construction Commission in 1841, and in 1843 was made Senior Privy Councillor (German: Geheimer Oberbaurat) for Infrastructure.

[6] His first completely independent work was the nearly three meter high tomb of General Ernst Ludwig von Tippelskirch in the Alter Garnisonfriedhof [de]) in Berlin (1844).

[7] He led construction of the Invalidensäule [de] war monument in Berlin's Invalidenpark (1851–1853) and designed the tower of the Luisenstädtische Kirche.

[11] The church was consecrated on the 28 October 1861, by the Bishop of Breslau in the presence of the King of Prussia, William I, the future Emperor of Germany.

[5] As Soller's work became known through publications, it influenced American architects Richard M. Upjohn and James Renwick Jr. in the mid-1840s, effectively initiating a Romanesque revival in the United States.

[3] Soller's work also influenced Miklós Ybl, one of Europe's leading architects and Hungary's most influential during the mid to late 19th century.
