John Allen Boyle is little known but the architect for three of Dallas' favorite, dramatic and picturesque residences. He designed the Sheppard King Mansion in 1916, what is now The Mansion on Turtle Creek. A mosaic dome is seen again at 2821 Turtle Creek, another Mediterranean style home. 4323 Overhill Drive also celebrates his use of stained glass, and myriad patterns of intricate ceramic tile. You can see the Mediterranean Moorish influences in all three. The terrace gardens down to the creek at 3828 Turtle Creek are reminiscent of the best Mexican stone and tile work of Colonial Mexico.
