I am planning to convert a small outbuilding for my modest studio setup.  I am totally new to studio construction and I will need to do a lot of reading.  As always with these kinds of setups I will be working to a very limited budget so any tips/advice to achieve the best results considering the limitations are very much appreciated.  I have come up with a general plan below which is certainly open to modification!!  I will add photographs here to show the progress (though it could be slow).



The outbuilding is of brick construction with an uneven brick floor and has a corrugated roof on top.  It has single doorway and no windows (see pdfs below).  I am thinking that I will retain the slight wedge shape to the internal room and have my monitors positioned at the lower end, though as with everything here this is open for discussion/advice.  I would like to achieve reasonable isolation as the building is pretty close to the house.

My general plan/checklist is as follows:
  • Design general layout
  • Purchase materials
  • Add two additional roof supports
  • Repair brickwork internally pointing/filling
  • Fill any additional holes/airgaps around the roof using expanding foam
  • Add a layer of DPM under the roof (just in case)
  • Add 3 coats of Wickes Liquid DPM to the internal walls (vapour/moisture sealer)
  • Lay 100mm level concrete floor over the existing brick/DPM with 142 mesh reinforcing fabric spaced centrally
  • Construct a disconnected studwork frame 1" gap between outer walls inside using 45 x 96mm/40 x 85mm studwork and 45 x 175mm joists
  • Install extraction fan
  • Fill all cavities with Rocksilk RS60 100mm mineral wool
  • Line with plasterboard 3 layers of 12.5mm (drywall)
  • Add acoustic treatments (corner absorbers first)

 

 

Any advice regarding the following areas is appreciated:
  • Floor construction
  • Ventilation
  • Door construction
  • Materials

For Rockwool/Rocksilk etc. use a density of either 45kg/m3 or 60kg/m3 - any denser is a waste of money. Paul Woodlock
