Theodor Kislov was born in 1914 in Buenos Aires, while his parents were in Argentina on a mission. At the age of six he came with his family to Eretz Israel and lived in Tel Aviv. He began his studies of architecture in 1935 with scorn in Paris and graduated after the Second World War at the Académie Royale des Beaux-Arts in Brussels. Upon his return to Israel he participated in the War of Independence after enlisting in the Engineering Corps. In 1949 he married Sophia Zuker (Sofia Kislov). After his discharge from the IDF he worked in the Government Planning and Building Department and in 1951 he opened an architectural and engineering firm called "Planning," which operated as a cooperative, and in 1954 the office built the first project in Eilat, and from then until the 1970s Kislov was an active architect in the city. Kislov opened a new architectural office in Old Jaffa, in cooperation with his two daughters, Tha Kislov and Liora Kislov-Kay, and his son-in-law, Olish K. Kyslov died in 1979, and the family office Atelier Kay-Kislov Kay Architects works to this day.
Kislov reached his great achievements precisely in the "banal" projects, the peoples. His works bear added value not only because of their lack of extravagance, but because his buildings and urban planning are intended for use by the entire public. The patio houses, for example, were simple engineering and easy to build, and he believed that one should not be skilled in building work in order to build them. He hoped that anyone could build his house on the foundations of the other. This is the most modest and sensitive construction. In the planning of the "growing patio", which is the result of the idea of a house that grows with its residents, lies the special relationship to the family unit and the family connection. Other solutions, such as the common playground for students of the Etzion Gever school, or the layout of the patio buildings in contrast to the high estates, create mutual relations and dependence between them, attesting that sometimes the architectural truth can be distilled into a simple, transparent and unequivocal statement.
Among his familiar projects in Eilat are Eilat Hotel, Neptune Hotel, Patio Neighborhoods, two cooled schools, a field school, the Egged Central Bus Station, the Egged Garage, the Laguna Mall and many others. The Eilat space led him to use innovative means such as breaking mass, diversifying materials and exploiting shading and local wind directions. In these projects he proposed low budget construction for residential, commercial and public use, a visual and programmatic adaptation of the project to a place, and intimate architecture that ensures mutual relations between the public domain and the private sector.
