When an attic access stair is taller than 10 ft it needs 13 treads and standard construction stairs will all be 25" wide or wider. The top of the line "Prestige" steel telescoping stair from Rainbow will have a cost 3+ times that of a standard wooden folding stair but model # M2254H has an RO of 22.5" x 54" and will serve a max. ceiling height of 11-6. For such a tall stair I would not use anything less strong than a Rainbow. Here is a link that might be useful: Rainbow Attic Stair

A photo of the area in question would be helpful. In general, I'd keep the steps the same width as the platform. I don't understand your statement that "wider steps would make the steps seem less steep." And you did mean 7" riser and 10" tread, right?

The architect did what he did probably because your front porch (and front elevation for that segment of your house) is divided into three bays. Your front door and fenestration (windows) are symmetrically centered on the front elevation. Thus making the stairs more or less the same width as the center two bays, while having matching porch railings for the remaining two bays maintains that symmetry. The front of your house is rather wide and the stairs shown in the elevation and plan are certainly in scale with the rest of the house. You may take some comfort in the fact that wide stairs are generally perceived as welcoming and gracious. If I had been the architect I would have done the same thing. Hope this helps with your evaluation.

You need wider treads. You should have at least 3/4” overhang from the face of the riser below. If you have extra treads you could rip a couple into 3/4” strips and glue/nail them to the back of the existing treads to make them wider.
