Hi,
I have placed the Laundry and bath on the top right corner of plan as it will be easier to do plumbing work because of already installed pipes and have also provided guest bedroom there so the guests have privacy as well as access to bath and laundry.
I have placed folding beds in the center area which you could use when you stay at this place with guests and have placed workshop/storage area on the right so you could also use the center space as workshop during day/work time.
Walk in Pantry is near to both guest bedroom and center room.
Ping Pong Table is placed as per your requirements and you could also have storage cabinets in front of utility room.
You can visualize your space in the renders.
Thanks.
