Nicolls Design Build at 1001 B Avenue, Suite 216, in Coronado holds CSLB licenses 1003454 and 871645 covering general building and electrical sign classifications, with 21 permitted projects on file across the island and greater San Diego. The firm's residential renovation scope — from second-story additions and whole-house gut remodels to ADU construction — generates the interior design coordination handled by studios such as Bungalow 56 Interior Design in the same B Avenue building for finish selections and spatial layouts. Commercial work includes restaurant design-build, tenant improvements for medical and law offices, and industrial fabrication projects across Coronado, Hillcrest, North Park, and Bankers Hill. Kitchen remodels on the island routinely involve load-bearing header removal for open-concept layouts, requiring structural engineering, shear-wall reinforcement, and re-roofing coordination with contractors such as Pacific Perfection Roofing when roof penetrations change during the framing phase. Construction documents produced at the B Avenue studio specify seismic tie-down hardware, marine-grade Simpson Strong-Tie connectors, and Title 24 energy compliance packages calibrated to the 92118 coastal climate zone.
