Tom Kenny here from Scott Simpson Design Build. We’re building two houses off of Voltz Road for two sisters that are going to be living next door to each other. Well, this is certainly the largest construction project in Northbrook, but it’s one of the largest construction projects combined in the entire North Shore. We started digging the deep portion of the sport court area first. The machine was so down below grade that you couldn’t see it from the street. There’s a garage right here, and underneath here is a porte cochère. There’s like a bridge right above me. You drive your cars through here, come into the garage from the back, and there’s a three-car garage from the very back of the property. Now we’re in the basement section of this property. If you look at the basement, this is the extent of their basement, and then you look over the edge here, this is where the edge of the sport court begins. We’re about 20 feet below grade here. Before we started the design of this sport court, we did a soil test where we shot two holes in the property 30 feet below grade. And what we found was this incredibly hard, cohesive soil. This is soil that can take 8,000 pounds of pressure every square foot.

What they do is they bench or bank cut the actual hole way back because when they pour these 18-foot concrete walls, we don’t want to have the soil cave in on one of the guys. So they build this really deep over dig is what they call it. That’s why the hole’s so big. We’re going to pour the foundation footings on either side. Then there’s these big, tall, like 18-foot foundation walls that come up from here. And then this will be like the actual level of the sport court. This is below the garage. So the roof is made of Spancrete above here, way up in the air. But on this side, once we pour the footings here, we’re going to pour a foundation wall that goes straight up. But on this side, we’re going to build a giant window well to bring light in so that this isn’t like a subterranean looking space. But it’s likely gonna take a thousand trips of trucking back and forth to complete the foundation here.
