There are no buildings surviving in Virginia that were known to have been built before 1650, therefore, no true picture of the Mottrom home can be presented.
However, there are enough facts known of the period to enable one to reconstruct a reasonably accurate picture of the first house on the Coan.
First of all—the house had to be strong, for life itself might depend upon the house. Its style was, no doubt, patterned after the architecture of England but modified by circumstances in the New World.
A framed building, one storey and a half high, with brick underpinning, and brick chimneys at either end, was the typical dwelling of Virginia about the middle of the seventeenth century. Its size would have been about forty by twenty feet, with downstairs ceilings about nine feet high.
We can visualize those workmen at Coan "riving" out the weather boards for the first known house in the Northern Neck. One of the men would be holding a rough-squared length of timber on a "frow" horse, while another would be pounding, with a wooden mallet, a wedge-shaped knife into the wood. Presently a board would fall off. With the same tools shingles for the roof would be split from cedar.
John Mottrom may have bought English bricks from some ship bound homeward with a load of tobacco and eager to get rid of the ballast of bricks at any price. It is more likely that his bricks were burned in a kiln at Coan, made with clay dug from the riverbank.
Nails were so hard to get that settlers when they were leaving to settle elsewhere burned their homes in order to get the nails to start a new house. Mottrom probably brought some nails from his former home and supplemented them with wooden pegs.
Rarely before 1720 were "windows sasht with crystal glass." Casements were used. Glassmaking had ended at Jamestown in 1624. Mottrom's windows may have been diamond-shaped panes of oiled paper with solid wooden shutters, or merely sliding panels of wood. But it was possible to get imported glass and he may have had some glass, drawn lead and solder from England. The window openings were a structural part of the framing, not just holes cut in the sheathing. Sometimes the windows did not open, as they were mainly intended to let in light. In this case the leaded glass was permanently set in the frames in diamond-shaped panes.
Mottrom's front door may have had hinges made in the shapes of the letters H and L, to stand for Holy Lord, for it was believed then that such hinges would drive ghosts away from the door. The door may have had panels in the form of a cross to keep out the witches. Or, the door may have been made of oak battens, heavy enough to keep out wolves, Indians and "hurry-canes." In either case, it was fastened with a latch and string, with possibly an oaken bar inside for added strength.
The chimneys of Virginia houses were much larger than those in England, and the fireplaces were at least seven feet across, for the hearth was the heart of the home.
