Internal garage regulations

[masona]

Hi all, long time no see, hope all are well! Slowly getting my life back together, however my question is,

I want to convert my front bungalow dining room into an internal garage, I'm struggling to find the correct building regulations, all I'm seeing is converting a garage into a room.

I know years ago, the concrete floor sloped to front and 100mm lower, non-combustible wall and 30mins fire door, is this still the same or could you point me to any latest building regulations link, I'm sure I don't need planning permission but just building regulations?

Thank you

1. slope to front, or 100mm step or coaming down from the house.
2. 30 min fire door plus self-closer.
3. There will need to be some insulation on the walls as the garage will be regarded as unheated space.

Thanks Tony, so I can do this without notifying building control providing I follow the building regs?

I also got spiral staircase in the back corner of the room which will be divided by a new brick wall approx 1.2m from the back existing wall right across forming a new hall way to the spiral stairs, can this wall be timber/stud wall with plasterboard or doesn't count as non-combustible wall?

You do still need to notify Building Control because you are altering the thermal- and fire-safety situation. You can use your local councils' building control service or an Approved Private Inspector. Either way you will get the Certificate on completion.

You can use a stud wall, but it would need to be thermally insulated and fire-resistant from the garage side for a minimum 30 minutes.
I think the wall might also need to have a degree of sound insulation (hopefully someone else could clarify). This can often be achieved by adding mass, such as extra sheets of plasterboard lining.

It would be best to submit a Full Plans Submission for bldg. regs approval. This will include construction notes/specification and when approved you will know how it should be built before any work starts on site. You will need a building designer , architect or architectural technician , to prepare the drawings and preferably submit the application.
