Well, no, even though it looked like it could have been the building wasn't on fire. The Terraces office block on Bree street appears to have unusual highly reflective pyramids on each corner of the building's roof. You can see what I mean if you take a look carefully at this photo taken by Damien du Toit.
If you're unfamiliar with Cape Town, then for reference, that's the V&A Waterfront in the top left corner; the colourful houses on the left (towards the bottom) are in an area known as Bo Kaap; and the CBD is slightly larger than the lower right quarter of the photo.
