KC Interior Design, a women-owned studio in Encinitas's Leucadia neighborhood, holds architectural designer and interior fitting contractor designations for modern and contemporary residential projects along North Coast Highway 101. The firm's open-concept kitchen and living-area remodels require dedicated electrical circuits and recessed-lighting layouts, scope typically coordinated with contractors such as Inada Electric for panel upgrades and dimmer-switch integration. A San Diego Mesa College interior design graduate leads the studio's work across Encinitas, Del Mar, Rancho Santa Fe, and Carlsbad, managing projects from schematic drawings through final installation. Design scopes cover space planning, custom cabinetry, tile selection, plumbing fixture specification, and large-format window-wall systems sourced from manufacturers like Western Window Systems. Interior and exterior paint programs coordinate color palettes and sheen levels with coating specialists including SR Painting for surface preparation and multi-coat application sequences. The most complex residential commissions involve full structural reconfigurations with steel moment-frame installations, new-pour concrete foundations, and floor-to-ceiling glass curtain walls rated to California seismic Zone 4 standards.
