[1] He and his colleagues at Mellor, Meigs, and Howe were involved in the design and construction oversight of bank buildings, the students' hall at Bryn Mawr College, multiple personal residences of prominent individuals, and the United States Coast Guard's World War Memorial at Arlington National Cemetery, as well as a chapel at the Somme American Cemetery near Bony, France and a monument to the United States Army's Twenty-Seventh and Thirtieth Divisions between Ypres and Mount Kemmel, the latter two of which were commissioned by the American Battle Monuments Commission.

In November 1930, his article, "Simplicity Is Secret Of Beautiful Home: R. T. McCracken, Germantown, Pa., Has Achieved Striking Results on Limited Ground" which was published in The Buffalo News, presented a number of insights, including the following:[10] "'Garth' means a piece of ground, usually small, set aside or enclosed by a wall or other barrier.

Simple materials have been used throughout—a yellowish field stone, most of which was obtained from the cellar excavation, for the walls; brick chimney and shingle roof, and the interior walls of the three principal rooms downstairs are treated with a cement plaster treated by the masons, with a troweled finish and of a putty color.The grape room, located to the southwest of the dining room, is paved with brick, as is the path on the front of the house, while the garden paths are of flagstone.House Has Accent.The entrance drive, which is but 40 feet long and serves only as a place to run a car in and back out again, is paved with pink Belgian blocks, which lend color, texture and tidiness to the whole operation of entering....If the McCracken house has an accent, it is the fusion of house and garden.

[15] In 1934, Meigs' four-year-old brown gelding, Ortheris, won the Twelfth Annual Up-Country Hunter and Pony Show.

[16] In April 1936, his horse, El Rey Keno, won the first steeplechase race ever held on the grounds of Land Hope, his estate near Unionville, Pennsylvania.

[18] In 1939, Meigs' horse, Red Ned, won by eight lengths at Broad Axe, bringing home the Harston Cup during the Whitemarsh Valley Hunt; however, tragedy struck when another of his horses, Michaelangelo, fell and broke its back during a jump in the Skippack Plate contest that same day.

[20] The next month, his "black fencer," Coq Noir, won the Pickering Challenge Cup at Valley Forge.

[26] Meigs suffered a cerebral hemorrhage at his estate, The Peak, in Radnor, Pennsylvania, and was transported to the Bryn Mawr Hospital, where he died on June 9, 1956.
