Hi there, my name is Vanessa Yaguas, civil engineer and interior designer. I have worked in a lot of residential projects for US, as a designer, drafter, etc. I can offer to you a set of drawings for your remodeling, including: floor plan, roof plan, elevations, sections, etc. First of all, I will like to know if you have drawings of the existing house or if you can draw a sketch for me. After that, we can discuss about the changes you are going to do so I can start the drawings. Also, if you want, I can search in the council's website for standards and regulations.
Feel free to contact me to discuss these items and more, I'm here to help.
Looking forward hearing from you.
Regards.
