Chief proponents of this style of architecture included Robert Fellowes Chisholm, Sir Samuel Swinton Jacob, Charles Mant, Henry Irwin, William Emerson, George Wittet and Frederick Stevens, along with numerous other skilled professionals and artisans throughout Europe and the Americas. Structures built in Indo-Saracenic style in India and in certain nearby countries were predominantly grand public edifices, such as clock towers and courthouses. Likewise, civic as well as municipal and governmental colleges along with town halls counted this style among its top-ranked and most-prized structures to this day; ironically, in Britain itself, for example, King George IV's Royal Pavilion at Brighton, (which twice in its lifetime has been threatened with being torn-down, denigrated by some as a “carnival sideshow”, and dismissed by threatened nationalists as “an architectural folly of inferior design”, no less) and elsewhere, these rare and often diminutive (though sometimes, as mentioned, of grand-scale), residential structures that exhibit this colonial style are highly valuable and prized by the communities in which they exist as being somehow "magical" in appearance. Typically, in India, villages, towns and cities of some means would lavish significant sums on construction of such architectural works when plans were drawn up for construction of the local railway stations, museums and art galleries. The cost involved in the construction of buildings of this style was high, including all their inherent customization, ornament and minutia decoration, the artisans' ingenuous skills (stone and wood carving, as well as the exquisite lapidary/inlaid work) and usual accessibility to requisite raw materials, hence the style was executed only on buildings of a grand scale. However the occasional residential structure of this sort, (its being built in part or whole with Indo-Saracenic design elements/motifs) did appear quite often, and such buildings have grown ever more valuable and highly prized by local and foreign populations for their exuberant beauty and elegance today. Either evidenced in a property's primary unit or any of its outbuildings, such estate-caliber residential properties lucky enough to boost the presence of an Indo-Saracenic structure, are still to be seen, generally, where in instances urban sprawl has not yet
