About this gig

Are you planning to expand your home but feeling stuck on how to get the city to approve your blueprints without endless redlines?


I provide detailed architectural and structural plans for residential room additions, including existing-to-new connections, roof integration, and municipal permit drawings. Adding to an existing house is highly complex because building departments scrutinize how the old structure merges with the new. I engineer seamless structural tie-ins and layout extensions across CA, TX, FL NC GA, and NY, delivering a turn-key submittal package that streamlines municipal code checks.


What Your Room Addition Construction Set Includes:

Seamless Demolition & Existing Layouts: Clear drafting showing what stays, what goes, and how the existing floor plan transitions into the new space.

Flawless Tie-In Structural Details: High-fidelity connection details for foundation extensions, structural wall tie-ins, and continuous load paths.

Unified Roof & Elevation Integration: Geometric roof-line splicing details, eave matches, and exterior elevations that make the addition look like it was always there.

Complete Code Blueprint Core: Fully dimensioned floor plans, electrical
