This is my first post - please be gentle
After years of "making do" I'm soon to be in a position to build a "man cave" for all my noisy needs. The house I'll soon move to (vicissitudes willing) has sufficient space to build a detached studio building. I've done a fair amount of research already, but information relates to improving existing spaces rather than building a space from scratch.
Whilst building from scratch would seem the ideal opportunity to build an optimal structure, I don't have a background in the construction industry and need some guidance from the amassed wisdom of this forum. Since I'm still in the early stages of planning, I'd like to restrict myself to materials and construction of the building itself so that I can instruct a professional to draw up plans and obtain quotes from local builders. I intend to fit-out the internals of the building myself after the structure is complete.
There are a number of constraints on the building (eaves height limited to 2.5m, flat roof limited to 3m height, pitched roof limited to 4m height), and area cannot be "too large" to avoid difficulties with local planning authorities.
The studio will be located in a residential area and used for private, non-commercial practice/rehearsal with drums, guitars, bass, and electronic instruments. I'll probably want to incorporate an office/workshop area too. Nearest neighbours are around 5m distant. The space will potentially be used for drumming at 3am - so assume neighbours are light sleepers.
My starting assumptions are a single (combined mix/recording) space of around 4m x 7m. Since soil is clay (subject to heave/shrink) I'll assume a raft foundation reinforced with re-bar. It may be possible to lower the internal floor height to cheat an increase in internal headroom (though details for dealing with damp are also beyond my knowledge). Walls might be concrete block, possibly filled with sand.
The roof might be concrete beam and block construction to achieve sufficient mass. The roof may be pitched, or flat (and possibly green roof).
Knowing so little about construction (and studio construction in particular) - is this a good starting point? How might you modify this 'specification' to improve isolation?
Is a structure of this construction likely to also require full room-within-room construction internally, or would resilient channel likely produce satisfactory results?
I appreciate no-one can accurately predict the performance of this construction (and required treatment), but I am struggling to find the proper starting point for my project. It would be so much easier to get started if already had a room
Thanks in advance for all wisdom
Cheers
