My goal while I was designing your office space was to add some colour and more natural materials . The main themes are the Quiet Zone Cube, the Lounge Zone and the Meeting Room.
The Quiet Zone Cube I imagined as a space for creative and solitary work. I didn’t make a simple glass cube though this would go just fine with the overall design concept. I chose LACOBEL Glass panels (AGC Glaverbel) for the QZ cube because they are really really inspiring. The detail remains simple enough so the Cube corresponds to the elegant feel of the whole building. As to the office furniture I was impressed by all the materials and design solutions I saw on the web-site of BENE furniture. It is stylish, modern and creative at the same time.
One thing you may not notice: you mentioned that you wanted some aluminium elements in the interior so what I was thinking of (and did it on one of the sections) – if you write the Letters “AL” somewhere in the interior people will easily remember what your field of work is. My suggestion is to put the letters “AL” on one of the shelves in the office room (section 3-3). It looks a bit like a signature. And also I was thinking of huge letters “QZ” marking the Quiet Zone so that even newcomers will know to keep quiet.
Everything else you can pretty much see in the uploaded files.
