In 1936 Dill designed and began building a “modern” house of “concrete modular construction” on the southwest corner of Sixth and Marcy in Alexandria, the first time the technique had been used in residential construction.

First a deep tunnel was dug which provided 57 degree tempered air which was circulated for summer cooling and through a fireplace in winter months for heating. A poured concrete pad was then built over the tunnel and a one-story, 1,200 square foot, three-bedroom, two-bath, 38 by 32 foot house was completed.

The house also had its south elevation made primarily of glass windows adding solar heating in the winter months. The primary construction utilized flanged “planks” of poured concrete with a void filled with straw as insulation. The modern, forward-thinking house was placed on the National Register of Historic Places in 1973.

A second, extant, structure in Alexandria is Henry Austin’s 1875, or slightly later, frame livery stable built on a limestone base. No self-respecting village should be without a resident ghost and Alexandria’s came about in 1878 at James Conway’s log cabin which was later moved to the Big Sandy River. Conway was impaled by a drunken fall on a wagon tongue after which his wife’s body was found in a shallow grave nearby. It was her ghost which haunted the area several miles east of the village.
