Seismic Integrity

Built for
Lifelong Resilience

A house addition isn't just a room; it's a structural shift. We build for the extreme requirements of Los Angeles geology and hillside physics.

From drilling deep-set piers for hillside stability to reinforcing existing foundations for second-story loads, we ensure your home remains a safe sanctuary for decades.

Absolute Reliability

Expansion Fears —
Our Responsibility

We've structured our entire workflow to protect your family and your single largest asset.

Navigating the L.A. Red Tape

Planning an addition in Los Angeles means dealing with strict Title 24 energy standards, setback laws, and complex city building departments. We handle the entire life cycle of your expansion permits.

  • Title 24 Compliance: Ensuring insulation and glazing meet strict CA energy conservation laws.
  • Zoning Board Representation: Advocating for your project if setbacks require specialized city clearances.
  • Seismic Certificates: Guaranteeing all structural shifts meet the latest LA earthquake safety ordinances.

The "Wart" Fear: Seamless Architectural Continuity

Nothing kills home value like an addition that looks tacked-on. We are specialists in architectural matching. We source matching roof tiles, replicate specific custom stucco textures, and bridge floor levels with zero-trip-hazard structural transitions, ensuring the addition feels original to the 1920s or 2020s design.

Surgical Dust Isolation

Living through a major addition shouldn't feel like living in a quarry. We isolate work zones with zippered heavy-duty floor-to-ceiling barriers and maintain industrial-grade HEPA air scrubbers 24/7 during demolition.

Guaranteed Fixed Budget Contract

Expansion costs that swell mid-project are the #1 valid concern for LA homeowners. SkillSee provides ironclad fixed-price contracts. Once the structural plans are approved, the price in the contract is exactly what you pay—no "structural surprises" or hidden markups.

The SkillSee Art

The Art of Visual Integration

A successful addition should look like it was always part of the original blueprint. We prioritize the aesthetic soul of your property above all.

Texture & Trim Match

Meticulous matching of stucco texture, roof tiling, and window trim to perfectly mirror your home's original exterior.

Flow Optimization

We don't just add a room; we re-evaluate your home's entire flow, ensuring the new space connects logically to your existing floor plan.

Seamless Level Bridge

Expert structural bridge between old and new slabs to ensure perfectly level floors throughout the entire house.
