I could sure use some help with a porch project.

We have a long and narrow front concrete porch with a stone column at each end.

I would like to increase the depth of it so that I can navigate with my power chair.

I have come up with an idea,but I don't know if it will look right.

We are thinking of extending the porch past the stone columns and putting railing around the porch.

Oh, due to a large crack across the depth of the concrete porch, We need to completely cover the porch.

It would be cost prohibitive to tear it out and rebuild.

I want to cover the concrete by building a wood porch and extending it to that it will have depth.

I also intended to place railing around the porch.

As you can see, I NEED ADVICE AND HELP .

I'm including a picture of one that is very simular to what I mean. You can see where the porch extends

beyond the wood columns.
