Our Process
Consultation & Feasibility
We begin with an in-home or virtual consultation to understand your goals, space needs, and property conditions. Our team evaluates your home’s layout, zoning requirements, and structural feasibility to determine what type of home addition is possible.
Design & Space Planning
Our designers develop a custom layout that integrates seamlessly with your existing home. We focus on flow, functionality, and aesthetics to ensure your new space feels natural, whether it’s a room addition, second story, or expanded living area.
3D Renderings & Scope Development
Using detailed measurements and digital scans, we create realistic 3D renderings so you can visualize your home addition before construction begins. We finalize the project scope, materials, and layout based on your feedback.
Engineering & Permits
Our team handles all architectural plans, structural engineering, and city approvals. We ensure your home addition meets all local building codes and San Diego regulations, managing the entire permit process on your behalf.
Material Selection & Pre-Construction
We guide you through selecting finishes, fixtures, and materials that match your home and budget. At the same time, we finalize timelines, order materials, and prepare for a smooth construction phase.
Construction & Project Management
Our licensed construction team brings your home addition to life with precision and attention to detail. A dedicated project manager oversees every phase, ensuring quality workmanship, clear communication, and on-time completion.
