Our house is not huge but there is plenty of space with only 2 of us living in a 3 bedroom house.  We have the luxury of a dedicated guest room which is listed on Air BnB as well as being available for family and friends.  The other bedroom is primarily my sewing and craft room, however, I do have a single bed with a trundle bed in the room.

The beds are not shown in this photo but are along the wall on the left-hand side.

Yesterday I did some minor rearrangements to turn this room into a bedroom for our 2 granddaughters who a visiting for the last week of the school holidays.

The sewing table has been moved.  I added a towel rail and a small desk which are normally in the guest room.

The repositioned sewing table allowed space for the trundle bed.

The girls have their own bedroom with minimal disruption to the household.
