What type of conifer is this?

[Avocadoseed]

I need to fill a gap for screening in my garden and looking for something quick and evergreen but doesn’t grow absolutely massive. My neighbour has this in theirs and it seems to be a smallish type, I would assume around 10/11 foot. Does anyone know what type this would be as this would be perfect for me.

Might be a Cupressus 'Wilma' or some sort of Thuja. Hard to tell.
I don't know my conifers without being at garden centre job to look at the labels and help me.....

Try your garden centre. Some of us are actually quite good at being helpful ;)
