Yes, but it'll have to be replaced elsewhere to comply. It can go outside on a rear elevation out of site and be reduced to 3" instead of 4" so can be made to look like a down pipe.
Oh, and welcome @Joss ! 👍
We had a dance with our enforcement officer because our front door style wasn't to plan; they told us to put in an NMA (pointing out that the door wasn't even visible from the road) -- which we did and the planning office turned it down because "any change to the principle elevation is not non-material". So we have (i) admitted that we'd changed from our original plan and (ii) our door was not to plan. Game set and match.
I suspect that its the 2m that triggered the reaction. That plus the fence looks nice and permanent. I'd be tempted to do a variant of what Peter suggested (i) don't put in an application; (ii) build a low bedding wall backfill with soil and plant the hedge. (iii) leave the posts, but remove the top 40cm of the fence or maybe and replace it with trellis. If you put in an application then you are effectively admitting that you are intending it to be a permanent structure. Stick to your point that you need some form of 2m fence because of the use of the safety issues, and keep to your line that it's just temporary. The issue will really become one of whether they think it worth the effort to execute an enforcement order for a temporary fence. If you've already got the hedge in place then its clearly not permanent . If they execute an enforcement order on removal of a 2m fence, you can immediately respond with "what 2m fence?" Don't put in the application, and just keep spinning it out. Threatening emails are cheap, but enforcement orders are costly to execute and pretty hard to enforce. Are they really going to take you to court for a fence that won''t even be visible by the time that you go to court? You could always add some "temporary" Hessian screening or plant some rapid growing clematis or honeysuckle to the trellis once the EO dogs have got bored.
Over the last few months have built a large single storey extension block with cavity and insulation on a currently empty property. We have recently had the flat roof done covering the entire area. The cavities got wet due to bad weather, so I've recently covered them and the external block work with sheeting as I'm still awaiting the arrival of the coping stones to close the walls around the parapet. There is plenty of airflow inside due to the Windows not yet being fitted. Particularly in this cold, damp, wet weather Some of the interior block walls are getting damp/wet and the roof joists and Visible roof steels are the same, most of the moisture evident where the joists sit on the external walls. I can't see it being the weather getting through the block work or down the cavities as they are now covered with plastic sheeting.. Is it likely to be condensation? Should I cover all the window openings as best I can to try and get the inside dry? Any advice would be helpful.....
