Ábaco Strategy’s Head Quarter offices are located at the historical Benjamin Thornton House in downtown Leesburg, Virginia.

History of: 17 Loudoun Street SE, Leesburg, VA ca 1805.

In 1761 Nicholas Minor sold lot #7 to John Davis with the provision that a structure be built that met Leesburg’s eighteenth century building covenant. The adjoining lot #8 had been sold previously to Daniel Davis, but deeds do not indicate that any buildings were constructed during this early period.

It is certain that no structures from the eighteenth century exist today on this property, which includes portions of lots #7 and #8 that were sold to Benjamin Thornton in 1805. In 1823, Benjamin Thornton transferred the present six-bay house to Robert Fulton. On the interior, much of the original early-nineteenth-century woodwork, floors, and chair rails remains intact along with fireplace mantels. A fireplace and the plaster wall finishes o the third floor indicate that the builder intended to use the attic as living space. The exterior of the house retains its basic form and composition including interior-end chimneys; however, the early-twentieth –century 1-over-1 sash windows that replace the original 9-over-6 sash of the first story and 6-over- sash of the second-story are later alterations.
