Expand Your Home
Without Compromising It
Expanding your home or modifying interior spaces changes how loads travel through the structure. We provide clear, permit-ready structural plans that keep your home safe, stable, and code-compliant through every stage of construction.
Why Structural Design Matters
Home additions act like new structures attached to your existing house. Foundations must support additional weight, framing must carry larger spans, and loads must transfer continuously into the original building without overstressing older members.
Interior remodels can present similar challenges. Removing load-bearing walls or enlarging openings requires properly sized beams, posts, and connections to maintain strength and control deflection. Thoughtful engineering ensures both the new and existing portions work together as one stable system.
Typical Addition & Remodel Projects
We frequently provide structural design for a wide range of residential projects across the Bay Area.
Horizontal Additions
New square footage attached to the existing home with integrated foundations, framing, and load paths.
Second-Story Expansions
New upper floors require careful analysis of existing walls, columns, and foundations to carry added weight.
Kitchen & Living Room Openings
Removing load-bearing walls for open layouts requires properly engineered beams and posts to redirect loads.
Large Window & Door Installations
Enlarged openings in walls need properly sized headers to carry loads across wider spans without sagging.
Key Structural Components
Beams & Headers
Engineered wood or steel beams replace removed walls and support large openings. Members are sized for span, loads, and deflection limits to keep floors level and finishes crack-free over time.
Foundations & Footings
Additions often require new or enlarged foundations. Reinforced concrete footings safely transfer loads to the soil and minimize settlement, ensuring the new and existing portions of your home perform as a unified system.
Framing & Load Paths
New framing must integrate seamlessly with the existing house. Proper connections and alignment ensure gravity and seismic forces travel continuously from roof to foundation without creating weak points in the structure.
