Along with the lighthouses of Pointe-au-Père, île Caribou, and Estevan Point, nine of the lighthouses constructed between 1906 and 1914 were constructed with the patented design of Miffonis, i.e., a prismatic form and a tower that is hexagonal or octagonal featuring flying buttresses.
This architecture seems to have been reserved for the tallest constructions, all carried out between 1906 and 1912.
It was not used thereafter although Anderson considered the concrete achievements to be "the ultimate completion in the art of building lighthouses."

Other types of lighthouses were constructed by the Commission des phares according to the plans of Miffonis.
The ten towers of less than 18.5 meters, built between 1908 and 1914, are of a "more sober" form, without buttress, providing a prismatic form over the entire length of the barrel : the lighthouses of Flint Island in Nova Sotia (1908-1910), of the île Parisienne in Ontario (1912), of Point Atkinson, Sheringham and Langara Point in British Columbia (1912-1913), of New Ferolle in Newfoundland (1913), and of Natashquan and île Sainte-Marie in Québec (1913-1914).

In his 1913 book, Miffonis states that these lighthouses, although less spectacular than those with flying buttresses, are much easier to build.
The “less spectacular” aspect of these lighthouse towers explains the “little controversy as to their design” as noted by historian Brigitte Violette.

In addition, Miffonis drew more conventional lighthouse plans, in particular that of Cap-Chat built in 1909.
The quadrangular structure is framed by four concrete pillars connected by wooden walls bent at the top by steel beams.
The plaster which was originally intended to cover the walls was instead covered with a facing of  clapboard.
