A well-designed guest suite gives visitors a sense of privacy and self-sufficiency without leaving the property. The best guest suites include a private entrance or courtyard, a full bathroom and a sitting area so guests can retreat on their own schedule. In the Santa Barbara Estate, Kingdom & Co. designed the guest suite with its own private courtyard featuring a water fountain and tree-hung lights, a sitting room with a desk and individual fireplace and a copper soaking tub surrounded by hand-painted tile. The result is a space that functions like a private casita within the home.
