| Comment | It is 100% possible just very expensive and being in a tenement is helpful in that the room size means you will have space to sacrifice
“First, address your walls. If you are able, consider decoupling them by creating a "room within a room". This is a separate 2x4 wall separated from your existing walls by an inch or so. If space is tight and it is new construction, then consider a staggered stud wall. Another alternative is to float the drywall by attaching the sheets to channels that are separated from the studs via clips. Add mass by layering at least two layers of 5/8" Type X drywall. Damp the drywall by putting Green Glue (or equivalent) between the sheets. Add absorption with insulation.
Then, do the same with the ceiling. Your ceiling is likely connected to either the floor above you or to the shared attic with the rest of the house. Decouple it by "floating" the ceiling, either using floating joists (in a "room within a room" concept) or via clips and channels. The former costs less from a materials perspective, but requires more room and is not always feasible. Add mass, damp, and add absorption the exact same way as the walls.” |
