In the 1920s, Hogg's brothers began to develop a new elite neighborhood, which they called River Oaks, which at that time was on the outskirts of Houston. For their home, the Hoggs chose the largest lot, . Ima worked closely with architect John Staub to design a house that would show off the art the family had purchased. William and Ima moved into the house, which she christened Bayou Bend, in 1928. In 1939, when she restored her estate along American lines, she donated more than 100 works on paper to Houston's Museum of Fine Arts (MFAH), including works by Cézanne, Sargent, Picasso, and Klee. Following the death of her brother Michael in 1941, she donated his collection of Frederic Remington works to the museum. Consisting of 53 oil paintings, 10 watercolors, and one bronze, it is known as the Hogg Brothers Collection, and is "one of the most important groupings of Western paintings on display in an American museum", according to Hogg biographer Neely. Hogg donated her collection of Native American art to MFAH in 1944, including 168 pieces of pottery, 95 pieces of jewelry, and 81 paintings.
