Come in earlier before the others arrive or come in later/leave later. No matter what scheme you use there will always be a means to interrupt you. The longer the overlap between you and others then the higher probability of interruption as it gives more opportunity to be interrupted. If you reduce the overlap then you squeeze interruptions into a smaller time slice, and you'll get more done.
