Interior and Exterior terrazzo
The white concrete terrazzo is meant to look like a seamless installation from the inside out. For the exterior a large format tile is being created out of the white terrazzo. For structural integrity the terrazzo is bonded to UHPC with 26,000 psi compressive strength, and incredible freeze thaw properties.
The entire house has extensive brass divider strips separating the rooms, other flooring materials, and shear walls. The brass was placed directly against the aluminum window frames, which meant that precision grinding was essential.
Brass divider strips have a 3/16″ cap that has an aluminum riser, grind to far and the aluminum is visible. For this reason, mapping the floor with depth cuts and laser levelling is critical.
This modern home does not utilize any baseboard or trim to hide unsightly gaps. This requires the terrazzo floor to be extremely flat, better than 1 mm over 3M. Tolerances this tight require new flattening techniques. To achieve these marks, the team created a depth cutting jig that was laser levelled and created router lines in the terrazzo. These marks gave the grinder / operator visual cues to know when they were close to height. Once the router cuts were removed, it was a constant game of mapping/ grinding until perfect.
