Dear client,this is my project and I hope You'll like it.I went with easy DIY project for making Murphy bed as it can be very expensive to buy one.There is 2 options that You will find in project.Also I have made desk that goes with this bed so You could completelly redesign Your room without too much expenses.Also I know that You said you don't need floor and ceiling redesign,but I just wanted to present it to You so You could maybe decide to go with it.Table and chairs go with this project just because Your chairs and table are not likely to go with this new stuff,and it is also just proposition.As main point of this project I made murphy bed with dimensions that are suitable for Your space and I have used space in wall to make it more blend in.
As I said I've redecorated Your space in case You decide to renovate it,but in case You just want bed,then You can keep all Your stuff and just use the hole in wall to ''hide'' Your bed.
It was interesting for me to spend my time in search of nice solution for You,and I hope You'll like it.
All the best.
