A time of change and new beginnings.

KBKC Design has a diverse portfolio of work from luxury residences in Northern California’s east bay, San Francisco and Silicon Valley to a Malibu beach house, to reimagined Boston row houses and Cape Cod “cottages”.  Our experienced creative team is the joining of east and west coast talents. Ken Costa and the Kathleen Burke Design Team are now a combined force offering one stop shopping. We are often asked “What’s your style?” Our style is your style plus. We are here to help you express yourself. The “plus” comes through our experience and creativity in designing, building, and furnishing something that connects with you in ways you hadn’t imagined.
