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.
The cost of a home addition depends on the size of the new space, structural requirements, and the level of customization involved. Additions can include new bedrooms, expanded living areas, or second story expansions. After reviewing the property and project goals, we provide a detailed estimate outlining the full scope of work.
Home additions typically take several months from planning to completion. The timeline includes design, permits, and construction. Larger additions or second story projects may take longer due to structural engineering and city approvals.
Yes, home additions almost always require permits because they involve structural construction and building code compliance. Our team manages the permit process and works with the local city to ensure the project meets all requirements.
In many cases homeowners can remain in the home during construction, especially if the addition is built in a separate area. However, certain phases may temporarily impact parts of the home. We communicate the schedule clearly so homeowners know what to expect.
Home additions can include room expansions, additional bedrooms, extended kitchens, new living areas, or second story additions. Each project is designed to integrate naturally with the existing architecture of the home.
Adding livable square footage can significantly increase a home's value. Expanding functional spaces like bedrooms, kitchens, and living areas often improves both daily comfort and long term resale potential.
