Evergreen shrub ID help ?

Hello all ,
I'm hoping somebody can identify an evergreen shrub that I have in my garden so I can find out how much/when to prune it . It's really got way too big at around 10ft tall and unsightly brown patches have started to appear on it , the foliage has a slightly lemony smell when rubbed between your fingers. If it helps ... the foliage is very soft , not stiff like pine needles and I've never seen any kind of cone or fruit on it .
It's said a picture is worth a thousand words so here are three pictures including a close up of the foliage .

I'm sure I've seen something like this in B&Q, cant remember the name though:dh:

 

I dunno, but I quite like the look of it.

looks like it been clipped to shape.

Got a bit of a juvenile juniper look about it.

 

It could be Chamaecyparis pisifera Squarrosa.
