Wall cabinets/cupboards

[Zell]

Next week I'm moving house and the bedroom is significantly smaller in my new property then my current one. Because of this I am going to have to have most of my storage in the form of wall units and shelves.

However, I'm finding it incredibly hard finding anywhere that sells single wall units. There are plenty of campanies that provide fitted bedrooms with wall unit options included, but I'm struggling to find any retailer that just sells cupboards that are suitable for being mounted on a wall.

Can anyone direct me to such a retailer? Does this kind of item exist, or am I going to have to resort to building my own set of units?
