Shrub help please

Hi,

I need a bit a help with this shrub outside the front of my (new-old) house.

Firstly - could someone please identify what kind of shrub it is?
Secondly - I want to trim it right back so that it is flush with the wall, will this be ok to do in one hit, or something I need to do over time?
Lastly - How to get the most fullness/ greenery out of it? Should I feed it?

Many thanks in advance.

 

Its a hedge, wouldn't like to say what kind of hedge, maybe some close ups of the leaves, does it flower etc. more info.
I would have said privet from the pictures but it looks too leafless to me and might well be something different.

I'd probably cut it back about 4 ins or more behind the wall and then cut the new growth back flush with the wall.

 

Sorry, yes, I meant a hedge.

I wasn't sure if it was a privet or not.

 

Some more closeups might help the ID, but it looks well established as a hedging plant so I think you could cut it back a bit, by going back a bit further than the face of the wall you will then be able to clip the new growth back to the face of the wall and hopefully have a greener appearance.
Obviously it not going to happen until next year now, so I'd do it around early March myself.

 

Thanks, I will post some better pics tomorrow.
