Spanish Colonial Home Expansion Design

Our 1935 Spanish Colonial in Los Angeles needs breathing room, so I’m planning two thoughtfully integrated additions aimed strictly at living-space expansion. The character of the original house—stucco walls, red-clay Terracotta roof tiles, arched openings—must remain the visual anchor, yet every new square foot has to comply with current California Residential Code, seismic requirements, and Title 24 energy standards.

Scope of work covers the full architectural journey: site review, schematic concepts, permit-ready construction documents, and coordination with structural, MEP, and energy consultants. I will provide a recent survey, original PDFs, and photographs of existing finishes once we start. The combined footprint should land in the 600 sq ft range for the Attached ADU and 1000 sq ft for the "Casita." and merge cleanly with existing utility lines.

Deliverables
• Two preliminary concepts with 3-D massing (SketchUp or Revit)
• One selected concept developed into a 1/4" = 1'-0" permit set (plans, elevations, sections, details)
• Structural sheets stamped by a California-licensed engineer (sub-consultant acceptable)
• Exterior finish schedule and lighting plan that echo period styling
• Final package in PDF plus editable CAD/Revit files

Acceptance Criteria
• First-cycle LADBS review returns only minor comments
• New elevations match stucco texture, roof pitch, and window proportions of the 1935 façade
• Interior layout yields at least three total additional bedrooms, flexible living spaces and courtyard and rooftop garden themes.

Please share a portfolio link that highlights Spanish Colonial, Mission Revival, or similar work and outline your estimated timeline from concept to permit submission. Local site visits are welcomed but not mandatory; remote collaboration is fine and preferred for the designer with a compatible vision.
