How do I create extra height to my existing fence?

We live in a modern house which overlooks the neighbours. All I see is brick houses from my kitchen window image

I want to plant climbing and rambling roses together with clematis up and along my fence. If I were to support them with wire and eyes alone would this alone support the climbing plants and create an effective tall screening? or do I need to erect a trellis taller than the fence itself? I suppose I would need to consult with the neighbours first out of courtesy.

can anyone help me please?

    Could, if it's possible mount some 30cm trellis on top? Alternatively a pagoda would shield you from prying eyes especially covered with lovely climbers. It would also give you something to look at and scents in your house.

    Do be careful that your fence is strong enough before trying to extend it - the extra trellis, combined with climbers, will be heavy.

    Before attaching trellis check with the planning department of your local council -there are limits in some areas how high you can go.

    IME the max height allowed is usually 2m (6' 6''). So yes check with local council in case any local restrictions.

    Agree that the combined weight of plants can be heavy, so make sure that all panels etc are in good solid condition before allowing climbers to take over.

    A 2cnd trellis actually in front of the existing fenceline could work quite well. Height then up to you as not a boundary. Take care though if over tall & a windy situation. By leaving some space between the 2cnd trellis & fence maintenance of latter will be easier. You can also hinge the trellis to the fence to allow better access. J.

  • Hi All.

    Thanks for all your advice. I checked with the council, thanks sotongeoff, and yep jo4eyes, you were right. Hinging sounds like a great idea.

    Im having a pergola erected too Alina W, and just waiting for my ramblers to arrive...can't waitimage

    thanks again guys.


  • Rose,

    Do find out whether the responsibility for maintaining the boundary fence is yours or your neighbour's.This should be on the deeds.

    Do let the neighbours know what you intend to do.

    Do take Jo's advice to make a free-standing plant-supporting fence in your own garden instead of trying to add anything to the existing fence. Builders' fences are not always that good. By building your own you can use some really good posts well set in the ground The more you can afford to bring this fence into your garden the more height of the adjoining houses you will screen.
