In a concrete tower the neighbour you hear is usually the one above, walking. At Cassia, here is how the building is meant to keep that sound where it starts.
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 Cassia commits to, and whether they are tested on site or only calculated.
Cassia: The homes are as the dossier records.
Read it against the Kempinski Residences Miami Design District dossier for the nearest comparison.
Stone, tile and wood carry impact sound into the slab. Declarations usually require an approved acoustic underlayment beneath any hard floor, and a few require a test once it is laid. Ask what the rule at Cassia says, whether the developer’s own finished floors meet it, and whether an owner who renovates must submit the product and its rating to the association before work starts.
Cassia: 174 turnkey residences, one to three bedrooms, 662 to 1,439 square feet; 58 one-bedrooms, 15 one-bedroom plus den, 85 two-bedrooms, 16 three-bedrooms; flexible ownership with a minimum 3-day stay; optional professional management; assigned parking included.
Some noise comes from the building itself: an elevator shaft beside a bedroom, a trash chute behind a wall, pumps, generators and cooling towers on the roof or the amenity deck. Read the floor plans at Cassia for what sits on the far side of each bedroom wall, and ask where the mechanical rooms sit in relation to the lines under consideration.
Cassia: More than one acre of amenities: resort pool, spa and wellness, fitness centre, indoor pool, yoga and barre, social club, co-working.
Laminated impact glass usually cuts traffic and boat noise better than ordinary glazing, and a window’s OITC rating measures that outdoor sound. Ask whether the acoustic targets for Cassia appear in the construction drawings or only in the brochure, and whether an acoustic consultant reported on them. The desk asks the developer of Cassia for the acoustic specification in writing.
Quiet is a number on a drawing. Ask to see the number.

A private report on the Miami market, sent when there is something worth knowing. No noise, no listings, no pressure.
Received. A note from the desk is on its way. If it has not arrived within a few minutes, please check your spam folder and mark it as not spam, so we can reach you.
We hold no listings and we are not the developer. Contact the desk at Miami Dossier and we will tell you what applies to your situation, what does not, and where we would not proceed. On this topic that means the document before the opinion. Where a question is legal, tax or structuring, we introduce you to advisers who handle that properly rather than answering it ourselves.
