With the support of Reşat Şemsettin Sirer, Rüştü Uzel, Halil Vedat Fıratlı, Tevfik Ararat, Abidin Mortaş and Ahmet Kutsi Tecer, the stage underwent a couple of renovation works and finally on 27 October 1947, it has started to host regular performances.

Additionally, as a part of the children's theatre initiatives during this period, Mümtaz Zeki Taşhan's plays "Altın Bilezik" (The Golden Bracelet) and "Karaböcek" (Black Beetle), along with Afif Obay's play "Büyükbabanın Pireleri" (Grandfather's Fleas), were also staged at the Küçük Tiyatro, introducing approximately 41,000 children to theater by the end of 1949.

Artists such as Mahir Canova, Madde Tanır, Cüneyt Gökçer, Muazzez Lutas, Salih Canar and Saim Alpago performed at the Küçük Tiyatro during this period.

Right after the establishment of the Ankara State Theatre, the first play staged here became Cevat Fehmi Başkut's "Küçük Şehir" (Small Town) on 1 October 1949.

While the balcony has a curved and sloping plan, the seats in the main hall are arranged in a straight manner.
