The building at Kalpaka Blvd 7 was designed in 1874 as a 4-storey tenement house, and the author of its design was the first academically educated Latvian architect Janis Fridrihs Baumanis (1834-1891). In 1879 a roof floor was added, and lucarnas were made in the main facade.
 The building at Kalpaka Blvd 7 is made in classical style, being in perfect composition with the neo-gothic building at Kalpaka Blvd 5 and neo-renaissance building at Kalpaka Blvd 9. The main facade of the building along Kalpaka Boulevard has retained its inital decoration: at the first floor level the facade is decorated with horizontal grooves made in plaster, as well as with decorative key-stones above window openings.The second and the third floors are visually joined by large canelurred pilasters with capitals of Ionic order. The fourth half-floor is marked from both sides by profiled cornices and moulded ornamental belts under them.
 In 1906 an extension at the rear of the building was made according to the project of the architect – tehnician Friedrich Scheffel.
 In 2004 the construction of the new part of Kalpaka Park Residence is completed according to the design of the architect Zane Kalinka. The facade of the new building faces N.Reriha Street and is made in quiet modern forms, characteristic to projects of Z.Kalinka. Aluminium – glass constructions make an original contrast with the old buildings of N.Reriha Street. An interesting spatial solution and a gain for the new building and the entire N.Reriha Street is the "recession" of the new building from the building line of the street. As a result spacious terraces were obtained at the second, third and fifth floor levels. Also, with the recession of the new building further in the plot, the historical buildings at N.Reriha Street remained untouched.
