John W Boylston was the architect that designed Idylease for Dr Edgar Day who was the founding member of the Newfoundland Health Association. He was born in 1852 and died at the age of 79 on April 19, 1932 in Ridgewood, New Jersey. He retired in 1927 after long association with the New York firm of J. B. Snook Sons. He was Snooks son-in-law.

Snook was responsible for the design of a number of notable cast-iron buildings, most of which are now in and around the SoHo neighborhood of Manhattan, as well as the original Grand Central Depot for Commodore Vanderbilt, which preceded the current Grand Central Terminal. He also designed several Vanderbilt Mansions that adorned 5th Ave for William Harry Vanderbilt.

Boylstons work was concerned chiefly with the designing of office buildings and hotels. In 1920 he became an associate of the American Institute of Architects and was affiliated with the Brooklyn Chapter.
