The Modular Soundroom Builder’s Guide is an extensive start-to-finish resource for musicians and audio-related professionals wanting to build a highly effective soundroom (a.k.a. soundbooth, iso-booth, etc.) with a fairly basic set of tools and building skills.
Soundroom Features
- Spacious interior
- Modular for storage & moving
- Extremely sturdy, dense walls, floor, & ceiling
- Interior sound treatment options
- Lighting options
- Full-size door & double-layer window
- Expandable & customizable
- Focuses on quiet construction methods
What’s Included In The Guide?

This guide minimizes headache, reduces waste cost, and drastically speeds up your build time so you can focus more on USING your sound room…not building it. It can be followed step-by-step or simply as a reference point for a custom build.
This is a realistic build with impressive performance. Here’s the proof.
I put this soundroom to the test by cranking my Mesa Single Rectifier and Mesa 4 x 12″ cabinet nearly to max volume (far more than I would ever use for recording). Here are the results of that test:
A Little Background
I’m a musician (surprise!) of almost 25 years with a passion for spreading industry, technique, and recording knowledge. Truth-be-told, I’m an equipment junky and spend way more time fiddling with music-related gadgets than I have time for, but that’s another story altogether. I also run a comfortably-sized YouTube channel, this website, and I’m the guitarist and primary songwriter in a band.
Also…yes, I just recently cut my hair. :\
Music is more than just a hobby to me; it’s a part of my identity. I just can’t not do it, and that was never an issue…until a couple years ago.
After owning a home for 10 years, I moved to a completely unfamiliar city with hilariously overpriced housing. I was stuck with a small apartment and it was pretty clear that making music was going to be challenging at best. This severely impacted and limited my growth as a musician.
Eventually I stumbled on the idea of building a modularized “iso-booth.” Ew, I know. Tiny “booths” are rightfully frowned upon by the recording community due to their “boxy” sound and coffin-like feel. Fair enough, but stick with me. What if it weren’t tiny at all?
Could a free-standing room be built with enough space to not only record, but maybe even practice?
Before committing to the idea, I took a look at pre-built options on the market. Everything out there was insanely expensive didn’t meet my needs. In the end, building a room made sense in my situation.
Unfortunately, apartment living complicated things. Rental property owners don’t typically appreciate their tenants modifying their buildings, after all. I also had no idea how long I would stay in that particular apartment.
Design Conception

My humble first sketch
Rather than build something I would certainly have to demolish and toss in a dumpster at some point, I naturally moved toward a modular design that could be disassembled and even moved to another location if necessary. It was around this time that I realized — “Holy cow, this might actually work.”
I eventually ran out of reasons to keep stalling, so I dove head-first in designing and building the room based on tried-and-true sound dampening and treatment principles over the course of about 4 months.
I had a hunch that this information might be helpful for others in a similar situation, so I recorded my entire build and threw up a quick timelapse video online. Suddenly I had someone new asking me for build plans almost every day. I took their cues, and after another 4 months or so, here we are.
Environment and Tool Requirements
You’re building a structure, so obviously you’ll need a screwdriver or two. More specifically, here are the base requirements for this build:
- A garage or place to build and house the soundroom
- 7’W x 9’L of total space for setup
- 8’H or taller ceilings
- A good cordless drill with plenty of drill and screw bits
- Inexpensive circular or table saw
- Basic hand tools such as screw drivers, hack saw, stapler, clamps, utility knife, etc.
- Safety glasses and work gloves
- Reasonably close access to a home improvement store (e.g. Home Depot, Lowes, etc.)
- A friend to help here and there
Who This is Not For
I’d love for this to be an option for anyone, but unfortunately that can’t be the case. If any of the following describes you, this guide may not be the right fit:
- Anyone building a booth can get a LOT out of this guide, but the step-by-step design is not meant for apartment or attached home dwellers with no garage or workspace for construction. Sorry!
- This build is cheap comparable to a full studio construction or a pre-built solution, but costs can still add up. I don’t recommend this to anyone on an extremely tight budget. Instead, a better option might be quiet recording options and/or investing in practice rental space.
- This guide focuses heavily on quiet construction. However, there will be short moments where you just need to use a saw, and a LOT of drill-work. If you have hyper-sensitive neighbors, check with them to make sure they don’t mind the minimal noise.
- Measurements are in standard/imperial units (inches). If you’re dead-set on using metric units, it could be a headache to do all of the conversions.
FAQs
I collected these questions from various online discussions, comments, and questions related to my build.
Is this a scam?
How long did this soundroom take to build?
How much did you spend?
How much does it weigh?
Do you have a version of this guide in metric units?
Why a rectangle? Don’t you know that parallel surfaces are terrible for sound reflection?
Why foam sound treatment?
What is this room best suited for?
How “soundproof” is this room?
Can I use this for drum practice?
How about drum recording?
Can I modify the size?
Why did you leave the outside unfinished?
If the room is sound and air-tight, how do you breathe in there?
I’m interested in purchasing. Will you answer questions if I get stuck in my build?
