John M. Faulconer, 93, a retired architect and builder who also was a senior engineer and naval architect for the Navy Department's Bureau of Ships, died of cardiac arrest Friday at the Colonial Villa Convalescent Home in Colesville.

A Baltimore native, Mr. Faulconer moved to the Washington area with his family as a child. He was educated at local public schools and private art schools and became skilled as a carpenter, builder and registered architect while a young man.

In about 1905 when, he recalled, there were less than a dozen homes and no water, sewers, electrical or telephone service in the area, he built his first home on Thayer Avenue in Silver Spring.

After his marriage in 1907 to the former Edna Knight, the couple built and lived in five more homes in Silver Spring, Four Corners, Colesville, and Sandy Spring.

Mr. Faulconer was an organizer and charter member of the Silver Spring volunteer Fire Department and an early member of the Silver Spring Masonic Lodge and Lions and Elks Clubs.

In 1914, he operated what was said to be the first soda fountain shop in Silver Spring. From 1922 to 1933, he was a partner in the building and architectural firm of Faulconer and Proctor and was instrumental in building homes and commecial buildings in Silver Spring, including Silver Spring's first movie theater, the old Seco, now Roth's Silver Spring West.

From the 1930's until his retirement in 1949, Mr. Faulconer worked for the Navy Department's Bureau of Ships.

Mrs. Faulconer died in about 1974.

Survivors include a son, Richard, and a daughter, Margaret Proctor, both of Silver Spring; a brother, Lauman, of St. Petersburg, Fla. seven grandchildren, 12 great-grandchildren and one great-great-grandchild.
