This page is a framework. Whether the building suits you is a separate conversation. Contact the desk at Miami Dossier for the current position on any building we cover.
Voices and music travel through the air; walls and floors are rated for them by STC, the sound transmission class. Footsteps, dropped objects and chairs travel through the structure; floor and ceiling assemblies are rated for them by IIC, the impact insulation class. The Florida Building Code sets a minimum for each between residences, and some luxury towers state higher targets. Ask which figures The St Regis Residences Sunny Isles Beach commits to, and whether they are tested on site or only calculated.
