Is it even possible?

I have a very small room.I stress on very small.The whole room could probably fit into one of you guy's closets :shock: Yet I have a knack for the strange and seemingly impossible and am willing to try. I have uploaded a hopefully ok sketchup file with my room. I am trying to work John's small room design into this space. Desired outcome: I want to use this room to track drums/vocals.The control room side will double up as an area for my guitarist and bassist to practice.They connect directly into my recording interface. Outside conditions: I live in the Caribbean,with only 2 seasons for the year,dry and rainy I cannot expand the room on the outside,as it joins to my garage and its neighbour's property on the other side No need for any sort of heating,I do not want to bake in here. Inside of room: Room Dimensions:9' x14 '. 6.5' high on one side and 9.5' high on the other side The floor is a solid concrete slab about 15" thick.My Garage also rest on this slab The roof is made of corrugated steel with aluminium support beams. The walls are going to be rendered for weatherproofing both inside and outside,I got permission from my neighbour. The is a steel support post in one corner as you will see,which I am going to fill with concrete The roof has a slope to it,I'm sure this will affect things a lot. Ventilation to be handled by a mini split unit ac Legal requirements: None.No building permits/building codes need to be adhered to,I have none unless I'm going to live in this room. Materials I have access to: wood-any size any shape,its very cheap here concrete gyprock rockwool No neoprene sheets sadly,but in another thread Gulfo said I could use re-bonded foam which I can get easily. I hope I gave enough info. Thanks in advance

as a general rules - make the outside structure as massive and weather proof as possible, make a massive separate inner room which parallels all the exterior walls and ceiling. then for treatments - slats and absorbers as needed to keep it alive for the drums but reasonably damped for the vox. how does this connect to your control room?

I think you misunderstand Gulfo,I'm thinking about the 2 room small studio design,or am I missing something?

New question . My roof is corrugated steel sheeting supported by z purlins. Is there any way i can add some mass to that? I'm thinking that this would be the weakest point in the room. Thanks

Change of plans.Mother has not been kind to me in the shed.I have flooding when heavy rains fall and the water seepage is cracking up my foundation.Luckily my mom took pity on my poor soul and is allowing me to use an unoccupied room in the house.Therefore I now have to design plans for a slightly bigger/taller room .My questions are: Do hollow clay blocks count as 2 leaves? I have a possible 3/4 leaf situation if that is the case...yikes.Sketchup file to follow as soon as I get the exact measurements of the room.Thanks so far. Shane

how hollow are the blocks? if could be challenging if they are thin and more air than mass...

http://abelbestcrete.com/products/block ... ng-blocks/ The first one from the top Gulfo. All the walls in the house are built with those.Being a tropical climate in the hurricane belt,our construction methods are different to what most people on this forum are used to seeing. About the walls, alternating rows of these hollow core blocks,locked in by the house's steel reinforced concrete pillars. The are joined together by a sand/cement mixture and rendered to about an inch on either side with the same sand/cement mixture. The walls are about 6 inches thick when finished.They are coated with water based paint on either side, about 6 coats in all i think. I have not begun designing as yet, depending on if I just have to add mass,or build decoupled walls. Sketchup file to follow today if time permits

i would treat them as a leaf but i'd first do some measuring to determine how much isolation they provide (or how much isolation you currently have given ceiling/roof and window/door have not been done. using sine sweeps, pink noise, and drum-bass music and a sound level meter to identify what isolation you have, and where so you get an idea of the next step.

As it is,the room is too open to run any sort of testing,as there are two open holes in the wall(doorways) that open into other rooms in the house.The windows on the right side will be blocked to accommodate an in-wall a/c. I'm thinking about a design like this. the square-ish area at the bottom right is for my drum set. Any suggestions?

that looks like a decent floor plan.

No sir. A block or even a brick will not develop an unbroken air cavity and by design of the brick/bock the material is bonded together front to rear by it's own layers which introduces the coupling that determines this material as one leaf. So how hollow the blocks are is irrelevant.

Thanks guys.Construction methods are different here because of the hot rainy climate. Another question. As you can see ,there's a big gap between the vox booth and the rest of the room. Can I hide this space with paper tape and paint over it,or will it be a problem?
