The North Terrace wing was originally built from 1801 to 1805 to house Jefferson's carriages and the horses and carriages of visitors, while most of Jefferson's horses were stabled at the east end of Mulberry Row. In Jefferson's era, horses and carriages were essential transportation, and over his lifetime he bought, sold, commissioned, and designed many kinds of carriages for his own use, ranging from simple one-horse, self-driven gigs to coaches drawn by teams of horses controlled by enslaved postilions. Israel Gillette often rode postilion on Jefferson's annual trip to Poplar Forest, and Isaac (Granger) Jefferson later recalled that when traveling in the phaeton, Jefferson often took the reins himself and drove hard when he wanted to travel fast. In 1782, Jefferson designed a phaeton, a small, two-passenger, open-bodied carriage, which was constructed at Monticello by William Orr, a hired smith, and Davy Watson, a hired joiner. He took it to France, where he acquired cabriolets with folding tops, chariots smaller than coaches, and a crane neck-style chariot made in London. During his presidency, he purchased a sulky, a gig, a double phaeton, and a Philadelphia-made chariot costing $1200 that saw little use, and he sold that chariot upon his retirement for $500. The tack room, horse stalls, and carriage bays in this wing were reconstructed in the late 1930s after falling into disrepair in the late 1800s and disappearing entirely by the turn of the 20th century, and photographs and later discoveries of Jefferson documents indicate that his plans for the wing differed from what stands today.
