Anyone done planning permission for a big shed?

[BringPizza]

Our existing shed is 300x480 and we're thinking of putting in a replacement of the same footprint but to use for gym kit. DH is 6'4" so on a treadmill he would need more than the 2.5m height allowed under permitted development (it has to go by one of the boundary fences- the neighbour is sideways to us so it's at the bottom of both our gardens). We'll get in touch with the local planners in the new year to ask how much of a faff it would be to apply for a pent-roof shed that's 3m max height sloping down to within the 2.5m limit at the boundary, but has anyone already done this, and was it a massive job like getting a full on extension built?

It’s unlikely Planning would provide you with any free and informal verbal pre-application advice. There isn’t any point in mentioning to them about the PD rules as you wouldn’t be complying with any... unless the outbuilding was to be positioned min. 2m from a boundary.

Unless you’re in a Conservation Area or the Green Belt, formal and Full Planning for an outbuilding should not be a major issue.

Thanks DevilDamo, we're in a village but it's not a conservation area. Looks like I'll just be filling in forms in the new year!

Does the shed come forward of the front wall of your dwelling on the street side?
We contacted planning about replacing an existing shed with a new structure before the old one fell down!
Because it was forward of the house front wall, we needed full planning. It was very easily done on-line.
One anomaly was that if we replaced the roof as one exercise and replaced the walls a month later - we would not have needed planning!

Straight forward process. Make sure you use the Householder application forms, rather than full planning permission. They are still for full PP, but require less information.

Thanks both. rslsys that's slightly bizarre! Shed is in the far back corner, but too close to the boundary on one side, so would need PP to be over 2.5m high.

@rslsys Outbuildings built on land forward of the principal elevation of the dwelling have always required formal Planning. Where houses are actually corner plots, this has sometimes caught people out as you have in effect two elevations that face highways. However, the PD guidance does state you would normally only have one principal elevation.

Our experience was totally bizarre, but ultimately very smooth.
We had an appointment with the planning department. Took plans, photos & pictures of what we wanted to build.
We live in an old farm house and there are several buildings on site.
The planner pointed to one on the Google earth picture and said "Do you live in this one?" Answer was "No, we live in the house behind it".
"Let me ask you again" he said in a voice one would use with the hard of understanding. "If you live in this building, it is closer to the road than the shed you want to re-build and therefore you won't need planning permission". "If you tell me you live in this other building, then your shed is closer to the road than the front wall of the dwelling and you will need planning!"
At this point DW revealed she was Chair of the Parish Council and therefore had to be seen to be doing the right thing. His response was to say "Oh $hit - can we start this conversation again?"
All very light hearted and we learned to interesting things. We do have another shed which starts behind the front wall of the house. On an inquiry about rebuilding this, the response was "So long as it less than 100m long and lower than the ridge of the house, we would have no interest".
Did the whole application on-line one August evening with a glass of wine on the patio. All the necessary maps and documents were available on-line. Just paid the fees and got the permission via e-mail a few months later.
