Not every tower needs to be tall — it needs to be tall enough, and the site decides what that means. At this SAVE Brasil site in the Atlantic Forest, a granite boulder outcrop already did most of the climbing. Six metres of steel finished the job, lifting the platform just clear of the surrounding vegetation instead of building height the landscape had already supplied for free.

It is the shortest structure in this portfolio, and also one of the clearest arguments against a one-size answer to observation towers: the brief here was never about elevation, it was about the last few metres needed to turn a good viewpoint into a usable platform.

The site had already done thirty metres of the climbing. The brief was the last six.
