The expansion of the street to a width of 20 Danish alls was adopted by the city council in 1906.

It began with Det Københavnske Byggeselskab's construction of Ny Østergade in 1873-76 and was followed by the expansion of Christen Bernikowsstræde, Nygade and Farvergade, and the creation of the Christian IX's Gade neighbourhood.

The buildings stand in blank, red brick with imitated sandstone details, a combination known from Christian IV's many Renaissance landmarks and is in Denmark known as Rosenborg Style after Rosenborg Castle.

The asymmetrical facade is broken up by centered bay flanked by pilaster-like structures and topped by wall dormers.

The canted bay at the corner of the building, located closest to the Garrison Church, is topped by a characteristic cloper[check spelling]-clad spire.

The rear side of the building stands in blank brick with dressed ground floor.
