I am about to start to build a new detached garage at the bottom of my garden as the first stage of a general reburb of our house.
The size will be 4.5m x6.5m.
I am getting a man in with a digger to dig out for the base.
So 3 questions.
First, I am going to use the garage year round for working on the car and also to do some woodwork, so it needs to be fairly warm, with regards to the base, can I put kingspan underneath the concrete base(was thinking of 150mm reinforced slab)if so , should I lay it on a bed of compacted type 1. Is it worth adding a DPM(if so at which level)
will it be ok bearing in mind the weight of cars etc?
Second question, this maybe should go in electrical.. while I have the guy with the digger there I was going to get him to dig a trench to the house to lay some cable in (16mm T+E for the supply, 2 coax for sky and cctv, and a cat5e just in case and a 15mm cold water pipe) how deep should I ask him to go? Also can these all be put in the same trench(eg electric and water, can I use standard 16mm T+E if I run it in conduit(plastic).
Last question, the garage is going to be timber frame, do the outside walls on the boundary line need to be of a fireproof nature? As I was going to clad in feather edge boards. Make up of walls will be (from inside out) 12.5mm te plasterboard, vapor barrier,150mm studs at 400centers full fill with 150mm insulation,15mm osb, tyvec breathable housewrap,2x1 battens finally fe boards. IS this spec going to be ok, heat wise and fire wise.
Any suggestions or other options I have missed ?
Will be doing all the construction work myself to keep cost down.
Thanks in advance.
