Room additions in San Diego, framed in-house.
Add a bedroom, a primary suite, a larger living area, or a second story. Additions are structural work first, and structural framing is what Troia self-performs.
Additions live or die on the structure.
An addition has to tie into a house that was never designed for it: new foundations meeting old ones, new rooflines joining existing framing, and loads that have to travel cleanly to the ground. Troia self-performs floor, wall, and roof framing to engineered plans, so the most important part of your addition is built by us, not handed off.
We also plan the parts homeowners do not see in the renderings: whether your electrical panel can carry the new space, how the HVAC will reach it, and how the exterior finishes will blend so the addition looks original to the home.
Start your projectBedroom & suite additions
Ground-floor additions for a new bedroom or primary suite with bath and closet.
Second-story additions
Adding a floor where lot coverage limits outward growth, with full structural engineering.
Living area expansions
Bump-outs and extensions that open up kitchens, family rooms, and great rooms.
Attached ADUs
Additions designed as independent, permitted living units with their own entry.
- Foundations and footings built to engineered plans
- Self-performed structural framing and roof tie-ins
- Electrical service and HVAC capacity reviewed
- Exterior stucco, siding, and roofing matched to the existing home
- Coastal and hillside requirements scoped early
Permits for home additions.
Every addition requires a building permit, and depending on location it may need zoning or coastal review. We coordinate with your designer and engineer, prepare the submittal, respond to plan check, and manage inspections through final.
In coastal communities like La Jolla, Del Mar, and Encinitas, height limits, setbacks, and Coastal Zone rules shape what is possible. We look at those constraints before design so you are not paying to redraw plans.
