We have an open landscape flexible workplace, I don't like it. The idea is that we don't have our own desks anymore and that we can sit on any location in the landscape, but nobody does that. People tend to sit at the same desk everyday. However as it is not your desk, but a flexible desk, you cannot keep your stuff lying around. So we need to put our stuff in a locker or keep it in our laptopbag/backpack.
Sometimes I leave my laptop on a desk with a post-it on it saying: "test-run in progress, do not disconnect or shutdown", just to have the feeling of having my own desk.
The open landscape, that doesn't bother me alot, maybe a bit more now our sales team occupies the same landscape, but it is OK. Sometimes it is annoying when making a lot of phone calls, but we do have booths to do such work or to do small meetings in during a project or when you really need to concentrate.
Most of the people are working with their headphones on, playing their own music. When it gets too loud somebody will stand up and ask to tone it down.
All in all it is an ok environment, with decent seating, big desks, but it saps out all the personality as you cannot decorate your desk or have some plants...
