[2] Although an exact date of construction cannot be determined, based on historic photographs of the area, it can be said that the structure already existed on this lot by 1860.

The Abreu Residence is a two-story, masonry and wood, commercial and residential building on the south side of Gonzalo Marin Street, in the historic center of Arecibo.

The base level is of stuccoed load-bearing masonry and the main, upped floor is of timber and clapboard construction.

At the commercial base level, two central rectangular entrance bays are flanked by smaller, square window openings.

A continuous base mold and a simple cornice delineate the lower and upper limits of the masonry base-story, respectively.
