My 1st post.... Small room sketchup drawing.

Hey there! Have been browsing the site for a while, and decided to have a go at posting. We are building an extension to our house in the suburbs, (Dun laoirghe, Dublin, Ireland) and one of the rooms is to be designated as a small studio/ guest room. The room is built (the walls are up, the roof is on), but we are a couple of weeks away from starting carpentry/ insulation/ electrics, so I thought id try to get some professional opinions on it before we jump in and mess it up! Attached are a couple of photos of the room in its current state. Its about 12'6" by 11'6" with a ceiling height of 8'8". The main goal is to have a room that sounds reasonably neutral for mixing. External noise is not a problem, and neither are neighbours. I usually mix at low to medium levels, with the occasional vocal, bass or guitar part being recorded in the room. There has to be room for a fold out couch so friends can stay over, and my girlfriend doesnt want too many wierd angles.... In other words the room should look someway normal(ish).... We have a budget of about €1000 over the price of constructing a normal room... although if we have to spend more we will. The music is mainly electronic pop. This is my first sketchup drawing, so forgive me if some things arn't too clear. (I really enjoyed doing it though!) I tried adding it as an attachment, but i couldnt seem to upload it.... Its quite big... nearly 8 megs that proberbly has somthing to do with it! HERE IS THE LINK The link sends you to a site called big upload... (if it works!) This is my 1st post and im not great with all things HTML.... As you can see (I hope) Ive made some attempt at designing a room with some sound control devices, but, even though ive gone through all the sites and read up a lot, im not very technicaly minded, and some of the science/ building techniques go right over my head, so I expect that ive got a lot wrong. We thought that it might be a good idea to insulate the entire room (walls, ceiling, floor) with rockwool. Underneath the plaster on the walls and ceiling, and underneath the timber on the floor. The idea is that this will tame the bass response a bit. Even though I didnt put them in the drawing, the front corners of the room (behind the speakers) would be bass traps. Hanging on the oposite wall the the window are a couple of boxes full of rockwool covered in material. I was hoping the couch would also go some way to taming the bass in the room...? Also, there is some kind of timber framed angled structure above the listening position (agian, Full of rockwool?) and the room will have lots of shelving full of books cds, which will hopefully be a positive thing for the sound. Thanks guys, im totally open to any suggestions/advice. Jesse (Dublin) :D P.s, ive attached some screenshots of the sketchup drawing incase it was too big to download.

(bumps politely) I know sometimes it takes a while to get to posts, but just incase i slipped under the radar... Any thoughts guys? :)

looks good! I'd put in some more absorption in the corner by the door. maybe hang an absorber on the back of the door also. if you could do it, maybe hang an absorber on the curtain bar or stand it up so you get a bit more symmetry at the listening position. you can probably put a small bit of drape on the end to pull over the window and it'll disguise it a bit. the couch will help a bit but if you can get both back corners with some trapping it may make more of a difference. I also have some ideas about stacking books to make your book shelf into a pseudo-QRD diffuser 8) if you check the attached image, you create a cardboard template of a proper QRD sequence - roughly based on width and depth of your shelves and then stack books to fit... if you want to add some efficiency, use color coordinated cardbooard or thin paneling to create "wells". you can still use the bookshelf and its probably a bit more efficient than random book placement... :)

Thanks gullfo, Yes id have to agree with you.... For the sake of symmetry it would be an idea to have some absorbtion on the window side. I have a friend (ive recently found out) who makes movable rockwool dividers/absorbers for studios on the side, so a couple of those would be very useful... they could be moved (if they were tall enough) to construct a makeshift vocal booth when i need it. Im still looking into the best/most cost evective way to have trapping in the back corners.... the purpose built bass traps you find on the internet seem very expensive.... The idea with the book shelves is very cool indeed! Ill try it for sure. Just a couple of things im wondering if you have an opinion on... Do you think that the speaker position (roughly) is too close to the wall? And, do you think that a large absorber like the one in between the speakers is the best solution? Thanks for you time and help, its very much apreciated! :D
