Second-story additions
Second-story additions in San Diego
When the lot is full but the family keeps growing, the best direction is up. A second story adds bedrooms and space while keeping your yard.
Why build up
Keep your yard
No footprint lost to the new rooms.
Stay in your neighborhood
More space without selling and moving.
Room for everyone
Bedrooms upstairs, living space downstairs.
Views and light
On many lots, the upper floor gets the best of both.
Engineering comes first
A second story puts new loads on your foundation and walls. Our engineers check the existing structure and design any reinforcement it needs before the plans go to the city.
Then we plan the stair location, the roofline, and how the new floor connects to the rooms below, so the house works as one home when it is done.

Common questions
Can my house support a second story?
Many can, sometimes with foundation or framing upgrades. Our engineers evaluate your home and design what is needed.
Do we need to move out?
It depends on the scope and how the work is staged. We discuss this with you during planning.
How much does a second story cost?
Cost depends on size, structure, and finishes. You get a detailed, itemized estimate after the free consultation.
