Dear Mr Paul,
My name is Brahmi Mehdi, one of the staff of your company's headquarters which is located in London and I am writing on behalf of my colleagues to express our concern about the working environment here which has become overwhelming mainly due to some recent changes.
Well, two employees have joined us recently and, as you already know, the office's surface cannot bear more than three people. As a result, the office has become overcrowded as we can hardly find space either to move around or to pile up our documents.
To put an end to this overwhelming situation, I humbly request you to arrange the adjacent room to our office which is used as an archive given to the fact that most archived documents thereare outdated and thus, they should be thrown away.
To enlarge the bureau, I recommend annexing it to the archive. Moreover, the archive's painting is quite ancient and peeled off and hence, it should be renewed.
I hope you will consider our request and we are looking forward to your prompt reply.
Yours sincerely,
Mehdi.
