Hi, my name is Vanessa Yaguas. I'm a civil engineer with experience in construction projects: architecture, interior design, structure calculation, etc. I read your project and I would like to help you. With my experience doing architecture design I can prepare a house plan that fits all your requirements , and also I can offer a simple 3D view for you to see how everything looks and help us decide the best way to design your house.
Also, if you need the slab foundation design, I can offer that too. As a civil engineer I have done that type of calculation.
I have worked with houses design for US, so if you want, feel free to contact me and I can share samples of my previous jobs.
Best regards.
