Home additions in San Diego County, room additions and second stories
Adding square footage is one of the most complex things you can do to a house. It touches the foundation, the structure, the roof line, and usually the electrical panel. David's architect background matters here, and it shows in how we plan before we ever break ground.

What's included in this service?
- Single-story room additions for bedrooms, family rooms, and expanded living areas
- Second-story additions including structural engineering coordination and existing roof modification
- Foundation work, stem walls, and slab extensions required for new square footage
- Full MEP (mechanical, electrical, plumbing) integration with the existing home systems
- Interior and exterior finishes matched to the existing structure so it looks like it was always there
When do you need this service?
- You are out of bedrooms and moving does not make sense given what you would give up

- Your family is expanding and the current layout cannot stretch any further
- You want to add a second story to maximize the lot without sacrificing yard
What do homeowners ask about Home Additions?
How involved is the permitting process for an addition?
More involved than most people expect. You will need architectural plans, structural engineering, energy calculations, and city or county review. We manage the whole process. David's background in architecture means we submit clean drawings that do not bounce back for corrections.
Will the addition look like it was added on, or will it match the house?
Matching is a priority. We use the same or compatible stucco profiles, roofing, window styles, and trim details as the existing structure. Most of our additions are hard to spot from the street.
Can we live in the house during an addition build?
Usually yes, especially for single-story additions where the main living areas stay intact. There will be noise, dust, and some disruption. We will be straight with you about what stages are roughest so you can plan around them.
