Im planning on converting my intergal garage into a study / computer
room.
I actually want to leave the garage door on (its a roller type) and
have about 3-4 feet of garage space, then a stud wall and then my study
behind it. Access to the study will be from my front hall.
I dont want to raise the floor so i would just have 1 or 2 steps down.

This means there will be no window, but i plan to have a lot of
lighting.

What UK regulations do i need to comply with if I am to do this
properly.

Currently my boiler and my electric meter is in the garage at the back.

Would ventilation be a problem?

Cheers

Doug

You may need planning permission. You WILL need building control.

If you are doing it properly, the building control will probably require the
following:

1. Insulated and dampproofed floor (i.e. you will have to raise the floor).
2. Any door between study and the small garage space will need a step down
(or a barrier sticking up from the floor space).
3. You may need to insulate the walls.
4. The stud partition will need to be fire resistant. This will probably
mean sticking 2 layers of plasterboard on the garage side with staggered
joins. Any door to the garage will need to be a fire door with an
intumescent frame.
5. You may need to install ventilation, as there is no window.
6. You may need to consider fire escape routes, as there is no window.
7. The room will not be usable as a living room or bedroom, as there is no
window.

This depends on whether the boiler is open flued or room sealed. Most modern
room sealed boilers require no ventilation from the house. An open flued
boiler with no ventilation will probably kill you.

You will need ventilation for the room anyway.
