Partnering with her husband, Pauli E. Blomstedt, her first works were noted for their functional, rather than aesthetic or decorative appearance and settings in park-like environments.
[1] She studied the new modern functionalism which in Finland focused on separation of the building structure from the façade and placing it in a park-like, healthy environment, full of air and light.
[5] Blomstedt and her husband completed the Kotka Savings Bank and began work on the Kannonkoski Church, before he died in 1935.
She and Lampén jointly completed several of the designs her husband had begun, including the Pohjanhovi Hotel [fi] in Rovaniemi, an important icon of the early modernist period.
[9][10] While the building was being constructed in 1939 Finnish actress Sirkka Sari fell off the roof and died during filming of Rikas tyttö.
[11] During the war, Blomstedt & Lampén were hired to design repairs to the Ruuskanen House [fi] in the Kyttälä neighborhood of Tampere, which had been bombed.
[19] That same year, the duo drew plans for the Nordic Union Bank and apartment building located at #19 Pitäjänmäki Road in Helsinki.
[8] In 1964, the duo built the Vuorimiehentie II Building on the campus of the Helsinki University of Technology in the Otaniemi district of Espoo.
[6] The three-story structure, topped by a neon sign, was constructed with a two-floor recessed entrance, overhung by the third-floor balcony.
The interior featured a bowed front half-cylinder stretching up to the balcony and minimal supports to the cashier's barriers, giving a feeling of openness to the space.
The design was industrial, with the steeple resembling a grain silo and was built in an open landscape of corn fields.
[34] The roof of the chapel sloped sharply, rising toward the tower,[32] which had slits resembling a radiator grill in the uppermost belfry area.
Surrounded by a park, adjacent to a flower meadow and forest, with winding paths for hikers, the hotel used the most modern construction techniques available.
The property is located in Kirjavalahti Bay of Lake Ladoga and was originally owned by the Helsinki pharmacist Tauno Yaskelyaynenu.
[36][37] In 1936, the Finnish Tourist Association bought the site of the former restaurant operated by the city of Hämeenlinna at the historic location of the Karlberg estate on the shore of Lake Vanajavesi.
Situated on a lake in a park setting, the hotel featured a restaurant, business lounge, office and music room, accessed from a spiral staircase on the ground floor in addition to the service areas and guest quarters.
The building was constructed of wood from Ingria and interior had seating for 500 people made of larch from the Lintula Forest in Raivola.
When the owners needed to modify the boiler room and create a storage area for flammable liquids Blomstedt & Penttilä completed the additional work in 1961.
The building served as the headquarters of the SYP party, was the location of the Nordic Union Bank and had nineteen apartments of varying sizes on the upper floors.
[55] When Lampén died, Penttilä was brought in to help Blomstedt complete work on the Oravikoski Mining Community.
[56][57] Blomstedt & Penttilä designed the teaching facility for the Department of Mining and Metallurgical Engineering, known as the Vuorimiehentie II Building, on the campus of the Helsinki University of Technology in the Otaniemi.
