Platte Fifteen is a five-story, 135,000 SF office building with 14,000 SF of ground-floor retail under construction at the corner of 15th and Platte streets in Lower Highland. It will be Denver’s first cross-laminated timber building.

Back in June, the project was at the big-hole-in-the-ground stage, with excavation finished and the underground parking getting started. Here we are four months later and the project is now up to sidewalk level and there’s a five-story stairwell core that’s already topped off on one end.

Let’s start right at the corner of 15th and Platte with zoomed-out and close-up views:

Here are three views along the 15th Street side, including a good angle on the five-story stairwell core:

We’ll wrap this post up with a panorama along the Platte Street side looking toward downtown:

Once the building has topped off we’ll stop by again with another update.
