Fitted wardrobes definitely look better, imho, than separates. But I'm not sure about the Hammonds or Sharps type companies. I know someone who has them in two bedrooms. They are big and really dominate the room, even though the house is a little bigger than average. The salesperson will try to fit as many pieces as possible into their design too. Personally, I would go for ones made by a local joiner so I could choose the sizes more easily. And I wouldn't pay for fitting before the things are actually fitted!
