The Carriage House was built in 1852 as part of the original construction. It was converted to a garage in 1932 when horse and carriage were replaced with automobiles. The original design was discovered during the Hollenshead's two year renovation. Great care was taken restore the "Carriage House" to exude the original character of the building. It now serves as a meeting place and space for gatherings with incredible gardens..
The wrap around veranda encompasses arbors, gardens and walk ways that offer intimate spaces as well as spectacular sweeping vistas of the valley below. There is a sunken formal garden and fountain that that are best viewed from the Carriage House's veranda.
The peripheral wisteria walkways pass by above and below the CH gardens. The CH is surrounded by century old beech, red oak, white oak, maple, cherry, and poplar trees. Wisteria and periwinkle grow freely as evidence to the gardens and plant material used by the temporary custodians of the property centuries gone by. These plantings are suggested in the 1852 publication, American Country Villas, by Andrew Jackson Downing, who was an architect and horticulturalist. Soledad, a literal translation of the Downing plan, is now one of best remaining, unadulterated, fully restored and maintained examples of his work.
