Entering Warsaw University of Technology, she began working for Romuald Gutt, a prominent pre-war modernist architect during her schooling in 1946.

She worked on designs for the Central Statistical Office building (Polish: Główny Urząd Statystyczny (GUS)) under his tutelage before graduating in 1948.

[5] One of Skibniewska's most known developments was at the Szwoleżerów estate, in which she designed a sought-after housing project known as Żoliborz Orchards (Polish: Sady Żoliborskie, 1958–1963).

[2] Organizing five-story buildings around a central courtyard, which had formerly been a garden, Skibniewska's plan included an influential development of the site.

Spaces between the buildings were designed as parks for residents and at the outskirts, she included a kindergarten, child care facility and a school.

[2][3] In 1974, she completed the ZETO building in Warsaw, the Sokółka Kindergarten in 1975 and between 1975 and 1986 she worked on a noted housing project in Białołęka Dworska [pl].
