Founded in 2006 by NCARB-certified and LEED Accredited architect Ken Parel-Sewell AIA, One World Architecture operates from Ogram Drive in La Mesa's Mt Helix area with a portfolio spanning residential renovations, custom new construction, and institutional facilities. Projects range from mid-century modern whole-house remodels to ground-up builds exceeding 10,000 square feet, with construction-phase execution coordinated through general contractors like Grahovac Construction Company in La Mesa. The firm holds architectural licenses in California, Kentucky, Illinois, and Georgia, enabling cross-state project management from its dual offices in San Diego and Louisville. Services cover the full project arc from schematic design and 3D visualization through construction documents, permit acquisition, contractor bidding, and contract administration. Sustainable-design principles informed by LEED accreditation guide material and system selections, an environmental integration that extends into site planning with Botanically Crafted Landscapes handling native-plant selection and irrigation design. Commercial tenant-improvement projects include shell-and-core design for medical and dental office buildouts, requiring Title 24 energy-compliance calculations and ADA-pathway dimensioning to meet California Building Code and San Diego County municipal-code overlay requirements.
