Which of these home alterations need planning permission or building regulations?

[KatyMac]

Which of these need building regs and/or planning permission please (not a conservation area)

Changing a back door into a window

Changing a utility room into a bathroom

Adding an additional kitchen (well changing one into a kitchenette and making a new one)

Converting a double garage into living space (no kitchen or bathroom)

Adding a door to split a hallway into two

Tia

I think, and I could be wrong, window to door and the garage conversion would need build regs.
If you are replacing the garage door with a window and it's facing the road, then that would probably need planning permission.

That's kind of what i thought

I want to get started as soon as we move in (well the garage at least) & i reckon PP takes ages

So are we thinking

Changing a back door into a window BR

Changing a utility room into a bathroom OK

Adding an additional kitchen (well changing one into a kitchenette and making a new one) OK

Converting a double garage into living space (no kitchen or bathroom) BR&PP

Adding a door to split a hallway into two OK

You don’t have to own a property to apply for planning permission, you just need to serve the owner with notice that you are applying. I have applied before owning a property and the builders started the morning after completion.

Ooo thats clever!

The garage needs to be first so I could maybe look into that

Check the council guidelines. Here an internal garage conversion doesn't need planning permission but does require building regulations. Anything to do with soil stacks needs planning permission (moving a toilet within an existing bathroom or adding a new toilet into another room even if it has plumbing and drainage needs planning). In all the houses on our estate for some unknown reason the soil stack is not in the corner of a room but 3 feet or so in from the external wall in the kitchen. The people who wanted to open the kitchen into the huge utility room to make a kitchen diner either had to move the stack or have a not fully opened area. So check where the soil stack is as it may cause you a problem!

Creating a downstairs toilet in our house only needed Building Regulations approval.

Oh thats a good idea

Typically our planning dont talk to anyone so we have condoning all online - ill have a go

The broad distinction is that planning permission controls the development and appearance of the property, while Building Regulations deal with how the work is constructed and its safety. You can need one, both or neither, so I’d avoid treating the list as a definite tick-box without seeing the drawings.

As a general guide: changing a door opening to a window is normally a Building Regs matter if the opening or lintel changes; planning may also apply depending on the elevation, permitted-development rights and whether it’s a designated area. An internal utility-to-bathroom conversion and an additional kitchen usually don’t need planning if there are no external changes, but drainage, ventilation, electrics and fire safety still need checking. An internal garage conversion normally needs Building Regs and can need planning if permitted-development rights don’t apply or the external appearance/parking is affected. An internal doorway is usually neither, unless it affects structure, fire separation or means of escape.

Before starting, send the proposed plans to the council’s planning department and Building Control and get their answers in writing. Also check the position of the soil stack and drains before fixing the bathroom layout; moving drainage can be the thing that changes the practical cost. Keep all approvals and completion certificates for when you eventually sell.

I think from reading my council website everything except the garage doors will not need planning (as the garage has no plumbing/kitchen or sleeping area its a hobby rom, clothes storage and for storage for ebikes)

The bathroom in the utility has a toilet the other side of the wall so fingers crossed; the other one may need a macerator 🙄😥

Our council is known for not engaging (apparently)
