carriage house doors

This may not be the place to say it, but I am very appreciative of ‘Montrose Morris’ ‘ writings and expertise. https://www.brownstoner.com/architecture/building-of-the-day-361-waverly-avenue/
There is no early photograph of this building in the municipal archives. There is a a metal track showing that the earlier doors were sliding. 361 was built in 1910.
My carriage house is next door. I was able to put glass panels in the garage doors because I was able to show early photos showing they had been their.
Is their a resource for the treatment of carriage house doors in the beginning of the last century that would help in regard to filing for renovation without Landmark glitches ? [IMG_3510](//muut.com/u/brownstoner/s1/:brownstoner:Umq1:img_3510.jpg.jpg)
