Extending Fence Posts

I used 50mm / 2” oak dowels. 500mm in the base post (mahoosive drill bit extension and an auger bit) and 300mm in the top.

I did use a bit of glue - but friction is happily doing the hard work. And don’t forget the cross pieces too. So far so good!
Awesome, thanks for the details!

Would be worth making a drilling template so that you don't have to measure each one.
There's not that many posts, but I have been doing some research into drilling decent vertical holes..

Trellis would probably be the easiest option. Only other option would be dowels and possibly utilising half lap joints to give a greater surface area for glue.
How would the trellis be attached to the top of a feathered fence?
 
Can't help with how to extend the fence, but be aware you will likely need planning permission for a fence over 2m (approx 6ft 6)

This seems crazy. If you bring it into your boundary, then you can go to 3 m under permitted development, but heaven forbid you attach it to your own fence! Glad you mentioned this though as we've been planning something similar. I think fences are typically 1.8 m, so we can only extend ours up 0.2 m by the sound of it. Quite an expense for 0.2 m.

Not sure this is correct? I can't see any reference to 3m and the Town and Country Planning Order makes no reference to the location of a fence in terms of it being on the boundary to a property. My interpretation of the below is that in most instances a fence is permitted development if it's no more than 2m above ground level or no taller than the previous fence. You may be confusing permitted development for extensions that has a 3m limit in many instances.



The Town and Country Planning (General Permitted Development) (England) Order 2015
Permitted development

A. The erection, construction, maintenance, improvement or alteration of a gate, fence, wall or other means of enclosure.
Development not permitted

A.1 Development is not permitted by Class A if—

(a)the height of any gate, fence, wall or means of enclosure erected or constructed adjacent to a highway used by vehicular traffic would, after the carrying out of the development, exceed—

(i)for a school, 2 metres above ground level, provided that any part of the gate, fence, wall or means of enclosure which is more than 1 metre above ground level does not create an obstruction to the view of persons using the highway as to be likely to cause danger to such persons;

(ii)in any other case, 1 metre above ground level;

(b)the height of any other gate, fence, wall or means of enclosure erected or constructed would exceed 2 metres above ground level;

(c)the height of any gate, fence, wall or other means of enclosure maintained, improved or altered would, as a result of the development, exceed its former height or the height referred to in paragraph (a) or (b) as the height appropriate to it if erected or constructed, whichever is the greater; or

(d)it would involve development within the curtilage of, or to a gate, fence, wall or other means of enclosure surrounding, a listed building.
Interpretation of Class A

A.2 For the purposes of Class A, “school” includes—

(a)premises which have changed use under Class S or T of Part 3 of this Schedule (changes of use) to become a state-funded school or registered nursery as defined in paragraph X of Part 3; and

(b)a building permitted by Class C of Part 4 of this Schedule (temporary buildings and uses) to be used temporarily as a school, from the date the local planning authority is notified as provided in paragraph C.2(b) of Part 4.

I'm not disagreeing with you, but buildings under 3 m don't typically need planning permission as they fall under permitted development. Why should fences be any different?

"If the extension is within 2m of a boundary, maximum eaves height should be no higher than 3m"

No idea on the rationale, was just clarifying that you cannot move a fence into your boundary then go up to 3m.

As a guess I'd say it's because a 2m limit on eaves height would be impractical as it'd result in the internal space being below headheight, where as 2m is a very common height for fencing that on level ground suitably obscures the vision between properties. Can't say planning legislation always makes a lot of sense though!

It does not. I was thinking more of building a secondary fence within the primary one. That would, I think, skirt around this stupid 2 m thing.

I'm just annoyed because now, if I want to put up a barrier between our garden and next door's, I'd have to get planning permission. What bothers me most is that they have a child who's always on the trampoline. He's a noisy *******. No matter where they put it, he'd probably be able to see in.

I've caught him looking through the fence a couple of times. Soon patched that up, and shouted at him.

A fence is still a fence regardless of whether it's within your boundary (or within another fence), therefore it can be no more than 2m regardless.

If you've a genuine need for a taller fence, then apply for planning permission :)
 
The more I see this post the more I think the correct solution is to replace the posts with new ones.
Especially if its not a particularly new fence.
Higher fence will apply higher load to those posts.

Good opportunity to replace and make sure they are well protected from rot at ground level.

Also decent chance of getting a semi rotted post out whole, rather than the ball ache of a snapped off one

Afraid to say, we're in brand new houses, and the neighbours have just had their garden done so they won't be keen for more disruption. Extending is the way.
 
Will the arris rails get in the way if you intend to drill down? How about timbers attached to either side of the posts, notched around the arris rails for more lenght and a stronger fixing. Then attach some trellis to that? It will probably have to be custom made trellis with the bays being 3 metre widths. Or separate posts for the trellis on your neighbours side. Again notched around the rails.

I don't think so, but that is worth checking, cheers. Timber supports either side isn't going to look like a seamless post. The separate post idea is interesting, I hadn't thought of that, but again probably won't be as nice as the extended post option.

If you wanted quicker rather than the drill/dowel method, you can get either universal extension brackets (2 for each post on opposite corners - any size post at least 3 inch), or extension sleeves (to suit 3inch or 4 inch posts). You'd still need to cut your new extension post at a matching angle or cut the top of the existing posts flat however.

Afraid those fall into the "no metal sleeves, cuffs or plates" category. I'm not sure I could even use them because I don't think there's a gap between the panels and post.
