The following is an except from the chapter history on ThetaChi.org, describing some of the history of the Bellflower house:

In 1943, the chapter moved into a new home at 11240 Bellflower Road, which was formerly the Halle family mansion. The Halles were a well known Cleveland family that owned a department store chain. It was a bold move to make such a purchase during the war, much like the boldness of buying a house during the depression. At the time of the purchase of the Halle mansion, the chapter still owned the house it occupied on East 115th. Before this house was sold, it was leased to the Navy for a short time for an on-campus training program for Reserve officers.

The changes [of the 1960s] at Case were first glimpsed in 1962 with an announcement about fraternity housing being built on south campus. Case required that all twelve fraternities sell their houses and give the school $60,000 to cover the cost of customizing a dormitory into a fraternity house. Through the Sigma Tau Delta Finance Corporation, the chapter house was sold to the school for $46,000 in 1968. A little over $41,000 was given back to the school toward a new south-side house. Since it was not the $60,000 in full, we were moved into a house at 1575 Mistletoe Drive until the time came to move south. 1968 was also the year in which Case and Western Reserve federated creating Case Western Reserve University, which seemed to create some added confusion at the time. According to alumnus Cedric Dilcizian ’68, the federation was looked down upon by the students of Case. Case viewed itself as on the move – but Reserve wasn’t. Also, the move by the chapter was viewed with mixed emotions. The chance of a better house was encouraging for the chapter which was struggling against the anti-fraternity feeling on campus. But the feelings ran deep for the Bellflower house after having lived there and owning it for 25 years. In 1971, under Brother Eger who had been a leader in the corporation and dedicated alumnus since the 1920’s, the Sigma Tau Delta Finance Corporation was disbanded and all holdings were transferred to Theta Chi which had just formed the Theta Chi Housing Corporation, even though it would be years before the new corporation would be a guiding force. By 1972, our account with the school reached over $43,000 but the university abandoned plans to build anymore houses on south campus. So the temporary move to Mistletoe would last from 1968 until 1986.

Brother Chuck Green (1968) lived in the Bellflower house and recently visited the new chapter house at 10819 Magnolia. He wrote up a comparison of the two houses, along with some interesting facts about the Bellflower house. Read his comparison here.
