Hi. After having read through your brief , the questions and your comments, I have a scheme I would like to present to you. Although you said you have a work area in your guest bedroom I have elected to provide you with a solution making use of the entrance / office area. My scheme allows you to close off the work area when you are expecting visitors and means your guest bedroom remains dedicated to this function - more flexibility and optimizing the floor area of your apartment. The space works very well as an office in which you can recieve clients without having to enter the private sphere of your home. I am happy to provide you with more technical details and furniture specifications etc if you like this solution. I look forward to your comments & feedback! Regards.
