Comprehensive House Extension Drawings

I already have the original CAD file of the property and a set of rough sketches that outline my ideas for the upcoming extension-renovation. Now I need the design package turned into clear, build-ready documentation.

Scope of work
• Update the existing CAD to show the proposed layout for the whole house, then create separate demolition plans so contractors can see exactly what stays and what goes.
• Produce new floorplans that tie the addition seamlessly into the existing footprint.
• Develop elevations with full architectural detail—window and door schedules, exterior finishes, key dimensions, and any notes required for permit submission.
• Add structural sheets that specify steel and wood members where they interact with the new works (beams, lintels, floor and roof framing). Connections, section cuts, and call-outs should be detailed enough for my engineer and local council to sign off without further clarification.

File format & hand-off
• Native CAD (DWG) plus PDFs ready for print.
• Layering must be tidy and consistent so my builder can easily toggle views.
• Please include one revision round after I review the draft set.

The quicker you can turn an initial draft, the sooner we can push this project toward permit approval. Let me know your estimated timeline and any questions you have about the existing drawings or site constraints.
