In early 1921, Wynkoop opened an office on 1261 American Avenue, in Long Beach and was connected with D. H. Archibald, a city contractor and builder. In December 1921, he completed the design for two $6,000 brick one-story, four-family apartment buildings at 620 New York Street. • Illustration — McGrath & Selover Architectural Contest 1924 On July 27, 1924, Wynkoop won second place out of 52 plans submitted in the McGrath & Selover contest under the direction of the Long Beach Architectural Association. The plan he submitted provided the design of a small two-bedroom one bath Spanish style home. At this time Wynkoop moved his office to the entire eighth floor of the Kress building (listed among the Long Beach historic landmarks). About 1930, Wynkoop married Adabelle May Roberts (1899-1953) in California. They had one son, Dudley, and one daughter, Nancy. In 1931, during the Great Depression in the United States, Wynkoop moved with his wife to Seattle, Washington, where he was a draftsman at the Metropolitan Building Company.

In 1937, Wynkoop relocated his family to Bakersfield, California, where he became the local architect with the Adams and Wynkoop firm. His office was at the Haberfeld building where he worked on nine Kern County schools and war housing in Lerdo, California. Architect Eugene Kinn Choy worked for Wynkoop in Bakersfield. Wynkoop divorced Adabelle May Roberts in October 1944 and married Virginia Rosemary Floyd-Tracy (1918-1998) in Carson City, Nevada. They had one son together, Thor Wynkoop.

Seaburst House
Seaburst House
• Illustration — Seaburst House, Wynkoop's second house on 26200 Scenic Road. Wynkoop designed and built a second home on Carmel Point in 1953 called Seaburst House, also called the Henry Johnson House. It is a mid-century modern Expressionist-style house at 26200 Scenic Road, between the Kuster's house and the Jeffer's house. The design was influenced by Frank Lloyd Wright's organic architecture style. On March 31, 1953, the Monterey Herald wrote an article with the title: Workman Begin Modernization Of Landmark on Carmel Point. The property was once the Col. Dutton's House, built in c. 1919. It was referred to as "The Warehouse," and "The Castle" by his neighbor Robinson Jeffers. It was a stone "shoebox" size house with large iron doors to the west of the "Sea Road," (Scenic Road) which at the time was a dirt road that was marked by driftwood stakes on both sides of the road.

The roof covered 138000 sqft of ground. Supporting arches were concrete, and the roof is a series of steel cables and vermiculite concrete that form an umbrella. The estimated cost was $700,000.
