IMO neither the porch or the portico says modern to me.

I like your choice of colors for siding, gutters, roof. I think it would look sooooooo good!

Here is some idea of overhang

You would need modern style light and numbers.

Hi Rosaura,

My first recommendation would be for any design to remove a slanted roofing as it would be difficult to compliment the rest of your roof. With the housing being timber I think either a laminate material or a timber, as in the image below, design would work best. The modern aspects I like about the photo are the hardwood battens on the right hand side, finish on the overhang, and the timber underside with lighting of the roofing. Possibly out of budget, to further 'modernize' it you could stain the pathway to look timber and add a glass wall on the right hand side of the entrance path with plants resting against it.

Hope that helps and let me know if there's any other concerns I could address.
