Historic Home Addition Design

I need detailed exterior elevations for renovations and additions on an 1823 plantation home that is a blend of Federal and Gothic Revival styles. The design is for an addition that will seamlessly integrate with the existing architecture, and to thoughtfully design a connection where a prior poor roofing choice has lead to water damage.

Requirements:
- Create accurate and detailed exterior elevations
- Create an architecturally respectful design appropriate for historic tax credits that incorporates modern elements and additions into historic home
- Ensure design / scale cohesion between existing home and new addition
- Complete the project within about a month

Ideal skills and experience:
- Expertise in historic architecture
- Proficiency in architectural design software for drawing elevations
- Understanding of blending historic and modern architecture tastefully
- Experience with residential additions

Please provide a portfolio showcasing relevant work.
