A number of architectural styles are represented in spite of Gammeltorv's small size and harmonic character. No. 14, 16 and 18 on the square's north side and No. 20 and No. 22 on its west side all date from the years 1795–1801 but none of the architects are known. The more monumental of the three houses is the Bachmann House at No. 18. The facade is decorated with Ionic order pilasters and is tipped by a triangular pediment. The Suhr House at No. 22 is also decorated with Ionic order pilasters.
