We currently need 5 double beds (x4 teens - 2 at uni) and will use the single bed on the plan as a TV snug. The large single space 5mx11m (kitchen, living, dining with no TV) also works better for how we live as a family as there are lots of us and their friends in and out - and they all have double bedrooms on the same level each with space for small sofa etc to retreat to.
When we sell we would allocate the room on the RHS of the front door as separate lounge/snug and maybe knock through to make the single bed an ensuite/dressing room for the master bedroom.
What do you think of the layout for selling in the longer term (one large K. L, D space and smaller snug lounge next to front door and master suite)?
