You don’t often see exposed concrete inside a house. When you do, it is in the basement, or on secondary structures like sit walls. Then again, a Koru house is not your typical house. The concrete wall in Red Butte is the mother of all concrete walls. Three stories high, 52 feet long and curved on a 180-foot radius, with cantilevered steel stair treads and lighting conduit, it is the house’s structural and aesthetic core. The wall is in two sections: one that divides the kitchen from the breakfast nook, and one that divides the living room from the entry room.
With such a complicated and important feature, there is no room for error. We had to be absolutely sure of the components and process before the form went into place or the concrete got poured. So, we created a mockup: a test structure five feet by five feet, curved to the same proportions as the interior specification, board formed for the same wood grain look, fitted with three steel stair treads identical to the ones that would be used inside the house. Architect, homeowner and structural engineer all got the chance to look at the mock up and either confirm that it looked and functioned the way it needed to, or propose that something be changed. Most importantly, our crew got the chance to practice the complicated procedure.
This level of thoroughness is central to everything we do at Koru. We understand that every once in a while you need to take a step back before you move forward. By taking a moment to get everyone on the same page, we ensure that the construction process runs as smoothly as possible, with fewer surprises down the line. It makes all of our jobs easier and all of our experiences that much more enjoyable.
