hey there

as a metter of fact i'm facing the same problem these days and here are some tips that i think could help you with further decisions

The idea of hiring a garage is a good idea although it might increase your
internal acoustic design budget. let me explain: let's say that you'll find a cheap garage in a very noisy environment or in a residential area. these facts should be taken under considerations if you are seriously thinking about designing a professional studio as it will be necessary to deal with the external and internal noises. Another issue that should take great part in choosing the right place is the size of the studio.There many 'ideal' sizes for control rooms and live rooms but if you find a place that can fit 42 Sq. meter control room and about 50 Sq. meter live room, it will work just fine. About the live room (studio), a good idea would be to build drum booth in order to minimise as much as possible the leakage b/w channels and if you can efford yourself, build another small booth for vocals. As you can see,there are alot of considerations that shloud take part in the whole process and carefull thinking can safe you a lot of money and stress in the future.feel free to write me to my Email
