He is best known for his contributions in the urban development of Kyiv, with buildings such as the House with Chimaeras, the St. Nicholas Roman Catholic Cathedral, the Karaite Kenesa, and the National Art Museum of Ukraine.

[citation needed] Horodecki was born into a noble Polish szlachta family of the Kornic coat of arms in the village of Szołudki (Sholudky, now Mukhivtsi Rural Council, Nemyriv Raion, Vinnytsia Oblast, Ukraine).

In Poland, Horodecki headed an American Project Bureau, "Henry Ulan & Co." Some of his designs were built including a water tower and trade rows in Piotrków Trybunalski (today in Lodz Voivodeship), a meat factory in Lublin, a bath house in Zgierz, and a casino building in Otwock.

One of Kyiv's streets, designed by Horodecki,[4] (between Maidan Nezalezhnosti and House with Chimaeras) was named after him in 1996 as vulytsia Arkhitektora Horodetskoho.

[5] In 2011, Horodecki's bust made of white marble was unveiled in the town of Nemyriv, close to the architect's birthplace in Szołudki.
