Dividing wall.

[Hungry Pete]

Hi, I’m wanting to divide half of my detached brick built garage to create a hobby workshop. It is well constructed from brick with a conventional tiled roof and a concrete floor with a damp course. I have power and light but no central heating , therefore it is quite humid but otherwise weatherproof.
My question is , can I use KILN DRIED timber for the framework which I will cover on one side with OBS board ? The dividing wall does not need to be load bearing and will be attached to side pillars and the floor as well as a cross member for the roof.
I’m concerned it may the framing may warp . It will be constructed using screws rather than nails.

actual fixings wont stop the wood warping screws are actually far better at stopping movement
fixing all round with no nails at floor level and full timber side to side at floor level to give you both rigidity and a fire step
keeping in mind the floor is likely to slop back to front this will also give you a point to level back from

My thoughts are to consider building a floor deck with the bearers resting on DPC strips. Think ahead to your desired workshop layout so you can properly plan sockets lighting and load bear patresses in the stud work for cabinets etc. Dry line the fixed walls and create you dividing wall with insulated studwork.The studwork should not move too much and quite frankly it is to be a work area not a sitting room. Construct an insulated ceiling so you end up with the best chance of keeping the ambient temperature and humidity fairly level.

DWD's description is almost word for word how I recently adapted a garage for a customer. It was a utility rather than a workshop and there was a door into the remainder of the garage but basically the same.

just to clarify in my suggestion with securing the floor timbers with no nails
the frame is rock solid even iff the no nails fails because the flooring is screwed into the floor plate so spread the load through the structure and by weight will give full support

I'll add that I fixed timbers to the walls as well and fixed the joists into them as well . Added insulation between the joists and screwed osb down as a surface.
