a zoning reclassification from RS3 to RT4 for the purpose of converting to a single family house and adding a third story.
My opinion is the third story won't make much of an impact on the street. The building is on the alley with a taller condo building on the east. The shorter bungalows to the west are already shaded by the two-flat. I don't believe the third story makes much a difference.
Just a few doors down to the west of 2215 W Winona (photo above) is a full second story addition on top of one of the bungalows. Pictured below is a newer construction house directly across the street. There are a few two and three flat buildings at the end of the block on the north side of the street.
The 2200 block of West Winona is a great block with wide and long lots. The block is adjacent to Winnemac Park. The converted single family home will be a great addition to the street and will continue the trend of higher-end houses (and higher home values) around Winnemac Park.
