Hello, I'm looking for some guidance on potentially constucting an indoor deck/loft in a lockout studio I rent. I'm renting the room for use as a music studio for my music projects. The room size is 12' W x 21' L x 20' H; it's in an old industrial building, hence the very high celing.
As you can see from those measurements, I have a TON of head space, but due to the amount of band equipment and desired layout for acoustical purposes, I could really use some more floor space.
So, I had the idea that maybe I could build a loft over a section of the room that is elevated approximately 8-10 ft, and dimensions approximately 10' x 12'. It will have to be strong enough to support several people walking on it, as well as maybe a couple hundred pounds of equipment. Ideally I'd like to cut down on vibrations as much as possible as well for acoustic purposes, within reason.
I plan on being in this room a while, so I don't mind spending a bit on it, but is a rental, so I'm not looking to necessarily make it super fancy. I've seen a few plans online that involved using 4x4s for the vertical posts with 2x8 horizontal boards bolted twice through each post, one on each side. It seems like a sound design, I'm just uncertain how I should space the support post for ideal support. Obviously, more is better, but I do want to utilize the space under the loft, so the less the better in that respect. Anyone know what the optimal trade of would be?
Anyone have any other ideas or tips as to what might be the best way to approach this?
I've attached a basic sketch of the room, the dotted outline box is the approximate location of the loft.
Standard wood deck construction methods will work--Except that you will need strong knee braces on the upright posts.
Here is a money saving thought---See if there is a used industrial shelving supplier in your area.
See if the have mezzanine parts available. You may find what you need in steel -cheaper than you can build your self---Easy to put up--easy to remove when you go--
I know this didn't answer your question exactly--I used to do millwright work--The used stuff is often nicely priced.---Mike--
