Soundproof Booth in NYC loft

The plan

Extrude an existing closet (2x4 feet) to create a (6x4 feet) sound proof work booth to cancel out the NYC noise. The booth has 3 inch thick walls with insulation all around including the door. This combined with recycled rubber mats reduces the amount of sound that can come through. I also prevented vibrations to come through by placing the beams on rubber fittings wherever the frames touch the wall or floor. The walls inside, including the ceiling, are built at an angle to prevent sound from inside the booth to bounce between walls. I brought in fresh air through the bottom and a silent fan to draw hot air out of the top.

To reduce waste, I used the original door as one of the walls and used all beams in the structure that were used to hold up the shelves inside the closet.

I created this 3D render in Cinema 4D to give me the measurements and see if the proportions would work.

Taking everything out

I removed everything out of the closet and built a quick desk setup to measure what would be the best. There will be enough room in the new extension to fit all this stuff back in and will further help to block sound.

Building the main frame and wall:

Attaching the rubber mats to the walls to minimize low vibrations:

Ventilation to draw air into the booth:

Placing insulation bats:

Added felt on top of the walls as a finish

Adding the last details like carpet, door handle and lock on the door.

End result!

Super comfortable distraction free workspace. This is also great for in the winter as this room gets really cold. The insulation blocks the noise but also makes this room super easy to heat up.

The booth also had enough space to store the items that were originally stored inside the closet. This helps further sound proof the space and prevents echo’s as well.
