Yes, a very sad loss. The Hawley stable and warehouse was built initially in 1877--at that time it was smaller, encompassing the left 2/3 of the building when viewed from the street. As far as I can determine, it was the first business in Central City directly served by the CCRR. Because it was effectively below grade, deliveries were handled using a slide connecting the siding behind the building to the to the upper floor storage area. The ground level at this time was a stable. This was the first of several gravity innovations to serve Central City businesses below the CCRR grade level.
In 1881 the structure was enlarged, adding the rightmost 1/3 seen in the current structure. In the process the original slide was inclosed in the structure. For about 15 years the building had it's original flat roof that included a fence on the along the trackside wall to discourage people from climbing on the roof.
Circa 1895 the familiar peaked roof and attic were added making the structure as we knew it until the fire.
Fortunately there are a handful of photos of the structure showing its evolution, one of the earliest showing the structure in its initial form on the opening day of the CCRR branch in 1878.
