I am thinking about converting half of our garage so I can use it as a office. We live in a new build house and the garage is attached to the side of the house and we have access to it from the conservatory.
I would like to do the job myself and have basic diy experience. The garage is breeze block both sides, our house one side and the other side is a neighbours garage. There is a single brick wall at the back. We already have electric in there.
I will keep the outside of the garage the same and divide the garage into 2 halfs. 80% office 20% storage.
I am planning on starting with the floor I was going to use 3x2 on a dpm and use polystrene for insulation. What size would i need 75mm ? Would Kingspan be better. I was then going to use chipboard on top.
The floor is 2.6m w and 3.6m d. I was going to use space the 3x2 out every 600mm.
Does that sound ok?
For the walls I was going to use 4x2 and use celotax for insulation. Do i need to use 100mm insulation as that will cost a bomb or could i use 75mm / 50mm and pack it out with something else? One wall is joined to the house and the other is joined to a neighbours garage. It just the back wall that is single brick.
Once again I was going to space them out 600mm so I could use 1200mm plasterboard.
Does that sound ok so far.
Thanks for the help
