Make 2 steps. I believe there is a code (or at least common sense) that requires the steps to be the same height.

Edited to add: I misunderstood the problem. I thought the 11" was to the ground, not to the door. Therefore, I withdraw my comments above. No way do you want two steps right at the door.

Typically, a poured concrete step would go there. Or you can use natural stone or a pre-cast concrete step. For a nicer finish on top of the concrete you can install tile suitable for exterior use.

There is NO WAY I'd want some goofy ass small concrete step there. The front porch was not poured to the right height and needs to be FIXED - the whole thing.

Can you imagine having a guest over and where do they stand to ring the bell? on the "lower level" and reach up? or balance precariously on the "add on" step so they are eye level, but crammed up against your front door?

Someone missed something here - and IMO, anything other than raising the entire porch will look bad. (unless there is an architect miracle worker out there - or someone with way better vision than me - but all I can imagine is the above 2 scenarios)

I'd try to raise the entire porch. Agree 100% and I'd try to raise it about 7 inches, if it were me to make a smaller step into the house.

I believe that the entire idea of a porch is to have a larger area that is about the same level as the house to provide a gracious entry for guests to "arrive" into the house.

I would NOT add a step....very awkward. You could do brick pavers on your entire porch. I don’t know exactly how much height it would add (bricks plus mortar), but it would definitely enhance the look of your front porch.

Why did the builder goof like that? It's not code. Maximum stair riser height is 7.75". It's on your builder to rep our the porch correctly and to code. As others said, adding a step is not an acceptable solution

Here is one more picture of doing a deeper step up. If for some reason doing the brick paver or raising the concrete is not an option hope you can find something that you like.

Ideally, the builder should have framed in a step with the porch pour. As it is, a row of bricks may have to be removed, so the height difference can be bridged in two steps.

Previous posters illustrate other attractive alternatives too.

One thing to note.....the pics posted here with the additional step on the porch are NOT finished in concrete. They are brick or other materials. It’s a very different look (and far more attractive) than a plain concrete porch with a plain concrete step added.

First image search put keywords - one step in front of door. Second was brick pavers porch.

Patio pavers are thicker than brick pavers to cover the porch with. That would only leave you doing one reasonable size step in front of the door. I'd be sure that the step has some visual cue to differentiate it from the lower porch level. That brick on brick look is a trip hazard!
