1500SF house needed a set of renovations to extend it in a 6000SF property. I only was given one part of the expansion plan which was an extension to both living area in the first floor and new master bedroom in the second level. This was a freelancing job.

Highlighted in pink is my part of the extension.

Roof framing visualization was important to adjust the height of the proposed extension. 

Roof Alternatives based on Structural requirements and Clients' need. Ceiling joists were eventually not required. 

New Extension foundation plan according to county specifications.
