I have finally managed to finish off most of the plans for the studio construction in full detail using QCAD software. Though not necessary for any council approval, as the size of the construction project is under 20 square meters (19.8m2), I still decided to spend some time drawing it. This will help me to keep changing the design, making sure it meets construction and safety regulations, as well as correct any mistakes. For project in this magnitude for a Home Recording Studio construction and budget, one cannot be too careful and waste money on wrong dimension cuts of timber and more.
As can be seen from the floor plan design, for soundproofing, it will have the concept of ‘room in a room’, by double wall construction, as well as two air sealed doors. The internal wall frame will have no contact with the external wall frame, with 40mm air gap. This concept is proven to be the most effective soundproofing design. I’m hoping to achieve more than 80db Sound Isolation/Reduction Levels. I should be able to play drums, guitar or bass and not be heard outside or at least at the boundaries of my land.
BUT, it does come at double the cost, since we are technically building 2 rooms!
The cost is not only the double timber frames, but the double sound insulation batts (Bradford Soundscreen R2.5), double 42mm solid air tight sealed doors and more.
Designing the plans also allows me to calculate the materials needed and the amount of each length of timber, plywood, fibre-cement cladding, insulation, roofing and so on.
Yes, it has no windows.
Next, is my budgeting and knowing the costs of all the materials needed.
Then, construction starts.
