Southern California Full House Renovation & Whole-Home Remodeling
Reimagine Your Home With Modern, Efficient, California-Ready Design
Transform your entire residence into a modern, luxurious living space with Guthrie GC—your trusted design-build partner for whole-home renovations in San Diego and Riverside Counties. Whether your goal is open-concept living, energy-efficient systems, indoor-outdoor flow, or high-end finishes, we bring decades of experience to every project and treat your home as if it were our own.
Our process begins with an in-home consultation where we assess your goals, layout opportunities, and budget. From there, we offer complete support through design, permitting (including Title 24 and CALGreen compliance), construction, and final finishing. High-performance upgrades like structural reinforcement, engineered lumber framing, smart-home wiring, and drought-tolerant landscaping are paired with premium touches such as frameless cabinetry, quartzite countertops, large-format porcelain tile, and matte-black hardware to deliver a space built for long-term beauty and function.

Our Full-House Renovation Process
Our renovation process begins with a comprehensive consultation where we visit your home, understand your goals, and evaluate layout opportunities. From there, our architects and engineers develop detailed floor plans, 3D renderings, and handle all required local permitting—ensuring your renovation meets Southern California building codes, Title 24 energy standards, and your design vision. During construction, your dedicated project manager oversees scheduling, subcontractors, inspections, and quality control while keeping you updated through regular walkthroughs and milestone reporting.
Once construction is complete, we install all final finishes, conduct a thorough quality inspection, and walk you through every aspect of your newly renovated home. Our commitment continues long after handover, providing post-project support to ensure your home performs beautifully and delivers lasting value for years to come. Whether you’re renovating a San Diego coastal home or updating a Riverside County property, Guthrie GC ensures a smooth, transparent, and high-quality renovation experience from start to finish.
