Additions & Remodels
Structural Design

Second-story additions, new rooms, and interior reconfigurations — including the load path, foundation, and lateral upgrades the existing structure needs to carry the new work. PE-stamped and permit-ready.

Second-story addition under construction on an existing single-story stucco house, showing new upper-floor framing built over the original structure.

Existing Structure Assessed First

We verify what the existing framing and foundation can actually carry.

Permit-Ready Stamped Plans

Drawings and calculations sized to clear plan check.

Works With Your Team

Coordinate with your architect, designer, or contractor’s plans.

Clear, Scoped Fees

Written scope and fee before we start — no hourly surprises.

What We Design

New area, carried by a structure that was not designed for it.

Additions are a load-path problem before they are a drawing problem. We start with what is already there, then design the new work and the upgrades the existing building needs.

01 · Vertical

Second-Story Additions

New upper floors, including the foundation, wall, and lateral upgrades required to carry the added mass and overturning.

02 · Horizontal

Room Additions

Ground-level expansions with new footings, framing, and the connection detailing that ties new to existing.

03 · Interior

Load-Bearing Wall Removals

Beam, post, and footing design for open-plan remodels — sized for the real tributary load, not a rule of thumb.

04 · Openings

New Openings & Headers

Window and door enlargements, including header design and the shear wall length lost to the opening.

05 · Substructure

Foundation Upgrades for New Load

Underpinning, new footings, and slab work where the existing foundation cannot carry the addition.

06 · Lateral

Lateral System Upgrades

Added shear walls, hold-downs, and diaphragm work triggered by the new area, designed per ASCE 7.

Interior of a home remodel where a load-bearing wall was removed — a new engineered beam spans the opening, carried by posts with bolted steel connectors at each end.

How It Works

Code Basis

Designed to current code. PE-stamped.

Designed to the current California Building Code and IBC, with loads and seismic design per ASCE 7. Every drawing set and calculation package is stamped by a licensed California PE — the engineer who designs it is the engineer who stamps it.

Scope

What we provide — and what we don’t.

We provide structural engineering only. Architectural design, Title 24 energy, and MEP are handled by your architect or designer — we coordinate with them. We do not perform general contracting and we do not build the work.
