The Jackman Group on Orange Avenue in Coronado is a design-build and interior design practice founded in 1978 by an NCIDQ-qualified interior designer, ASID member, and licensed California general contractor who holds CalBRE license 00875300. Full-scale construction projects — from foundation to roofline — bring in roofing subcontractors such as Summit Shield Roofing to execute the clay-tile and flat-roof systems common in Coronado's historic housing stock. The firm's portfolio includes the ASID first-place award–winning interior of Primavera Ristorante and the renovation of the Spreckels Building, for which the City of Coronado awarded its highest design honor. Historic preservation work on pre-war Orange Avenue properties often demands period-accurate locksets and deadbolts sourced and re-keyed through Coronado Lock and Key to match original Craftsman and Spanish Revival hardware profiles. Current services at 1172 Orange Avenue span design-build, interior design, certified staging, and new-home development, with construction scopes that include structural reinforcement of Coronado's 1920s-era balloon-frame residences to current California seismic code. The Orange Avenue address sits on Coronado Island's primary commercial spine, accessible to clients who cross the Coronado Bridge from mainland San Diego or ride the Coronado Ferry to the bayfront. Coronado's residential building stock ranges from the Victorian-era properties near Hotel Del Coronado at 1500 Orange Avenue to mid-century ranch homes and contemporary infill construction, each presenting distinct material and code challenges for the island's contractors. Residential design on the island must account for the Coronado Beach oceanfront exposure that drives salt-air corrosion, UV intensity, and the marine-layer humidity patterns that affect material selection from foundation to roofline.
