Winterham is situated at the crest of a hill overlooking the rolling pastures of Amelia County, north of Amelia Court House. The house is the only known Virginia building by Thomas Tabb Giles, an accomplished amateur architect, and William Percival, a significant professional architect. Their collaboration is recorded on the recently found designs for the house, now in the collections of the Virginia Museum of History and Culture in Richmond. The Italian Villa-style dwelling was built for John Garland Jefferson II about 1855, and some of its features are similar to designs found in books by Asher Benjamin. Winterham is a restrained but refined frame house with an interior cross-hall plan. There are four original porches on the house, each of a different design. The building was used as a hospital for wounded Confederate soldiers after General Robert E. Lee’s retreat from Richmond in April 1865. Winterham was converted for use as a bed-and-breakfast in the 21st century.
