An initial suggestion that comes to mind is the Cupressus sempervirens ‘Green Pencil’, which is very columnal: [LINK]https://https://www.shootgardening.com/plant/cupressus-sempervirens-green-pencil?referrer=%2Fplant%2Fsearch%3Fq%3Dcupressus+semperviren[/LINK].
A slightly smaller option is Cupressus sempervirens 'Totem Pole': [LINK] https://https://www.shootgardening.com/plant/cupressus-sempervirens-totem-pole?referrer=%2Fplant%2Fsearch%3Fq%3Dcupressus+semperviren[/LINK]
Hope these suggestions give you something to work with!
The photo shows Swane's Gold as being pyramidal rather than columnar. Which is it? How rapidly does it grow per annum? What is cost? I am looking for columnar conifers of mid-green colour to hide a brick wall 3m tall. I do not want pyramids; I do want pencil-shape. I need narrow width pencils as well since space between our windows and wall is only 4m
