[1] Meigs designed an elaborate Tudor Revival fantasy for "Glen Brook" (1914–17), the Caspar W. Morris residence in Haverford, Pennsylvania.
[2] Samuel Yellin fashioned custom metalwork for many of the firm's projects, and Mellor & Meigs designed a Spanish Revival workshop (1915) for him in West Philadelphia.
George Howe, who had graduated from the Ecole de Beaux Arts and worked in the office of Furness, Evans & Company, joined Mellor & Meigs in February 1917.
[3] Meigs was more restrained in designing "Ropsley" (1916–18), the Francis I. McIlhenny residence in Wyndmoor, Pennsylvania, whose innovative plan is credited to Howe.
[9] Their mature Neo-Norman style, an "amalgram of Howe's formalism and sensitivity to materials with some of the more theatrically picturesque elements of Arthur Meig's work,"[10] was repeated at Oxmoor (1926) and Pheasant Run Farm (1927–29).
"[7] Howe partnered with William Lescaze on the PSFS Building (1930–32) in Philadelphia, the first International Style skyscraper constructed in the United States.
