Conservatory being built - whose fence is it?

however glazing does determine the difference between a conservatory & an extension

Not as far as building control are concerned :beer:

But for the rest of us it generally does

southcoastrgi

can you then tell me what is the difference in BC's eyes between the two ?

I already have, post 21 which you responded to

no you have said where conservatories are normally exempt from building regulations, not what they consider the difference between an extension or a conservatory & this is down to glazing area & the roof material

They do however have to be built to an acceptable standard, and if not BC can and often do step in.

Actually you haven't. You've cherry picked one part of the newish L1b from where the 75/50 definition has been deleted but neglected to google other parts of BR documentation which have not been amended or where there remains some confusion as to whether they have been superceded or not.

Indeed different LABCs seem to be taking different views. In the extreme that which you quote would allows the OP to build a brick construction with a tiled roof and a pair of opening doors out onto the garden and still call it a conny and provided it meets those four criteria it will be BR exempt.

The 75%/50% definition remains bombproof safe from the OP's perspective.

He should consult his LABC to get their definitive view.

Cheers

As mentioned previously glazing area and roof material have no bearing on the current classification of a conservatory in regards to part L

It is possible to have a conservatory which has a pitched tiled roof, the roof would have to be certified by BC, but the structure would still be classed as a conservatory, essentially it would still be exempt from part L :j apart from the roof, providing it stills meets the criteria laid out in post 21:)

That would be partially possible, if you wanted to you could build it in a manner which would still allow it to be classed as a conservatory, but the roof and walls would have to comply with building regs so I can't see any real reason someone would want to take that approach

I don't see how I have cherry picked parts of L1b, the information I posted is straight from the goverments planning portal, designed solely to give an overview of the process, I have not selectively posted parts of it

I can't find any mention in the current regulations of the 50/75% glazing calculation being used, I don't think there is any confusion as to which regulations have been superseded. I would be grateful if you could provide me any insight into the matter, I'd rather not get any further into things before discovering I've got things wrong

I should state that I was also mistakenly under the impression that the 75% glazing rule still applies, see my thread regarding the conservatory I'm planning https://forums.moneysavingexpert.com/discussion/4698317

I've since discovered it's relatively easy for me to do what I want, I can't have a flat roof between the house and conservatory as I can't get the eaves down to 3m, if you run a single pitched roof into a flat roof the eaves height is taken from the side of the flat roof.

However the good news is I'd prefer a pitched roof anyway, I was only going down the flat roof as I thought I'd have to incorporate some roof lanterns. I'm basically partially constructing an extension, this allows me to get the slab and a couple of other things signed off by BC and means the planning permission won't expire after three years

Then I'm tacking on a conservatory to the start of my extension :rotfl: as it would never meet the part L requirements due to amount of glazing. The pitched roof between the conservatory and extension will be briefly covered in polycarbonate sheeting, I'll then apply to have the roof structure changed.

As I'm changing less than 50% of a thermal element, the roof, the new roof needs to comply with building regs but the existing double glazed conservatory roof doesn't need to meet them :beer:
I've had a chat will my local BCO and he doesn't have any issues with my proposals :j
