Highland Park is really two towns. East and central, around the downtown and Ravinia, the housing is pre-war: Colonials, Tudors and shingled houses from the 1910s and 1920s, many of them on ravine lots that fall steeply towards the lake. West of Green Bay Road the stock turns over to 1950s and 1960s ranches, split-levels and a notable run of mid-century modern houses.
That split matters more than anywhere else we work. The pre-war houses give us tall ceilings and deep joists to route a drain through, and hand us ninety-year-old supply lines to deal with. The post-war houses give us modern copper and a roomier bathroom, and put the waste run in a slab or a shallow crawl where it is far less willing to move.
So the first question here is not what you want, it is what year the house was built. It decides whether a relocated toilet is a half-day of framing or a week of concrete work, and it is the reason two identical-looking bathrooms in this city can be $15,000 apart.
