You often read this from young builders these days, bathroom and office on the ground floor should be age-appropriate for possible living on one level. But for that, the rooms are simply too small in terms of square meters. Of course, you can create a compact office that fits a double bed and a wardrobe and put a shower in a guest toilet. But that really has nothing to do with "age-appropriate." Even without a wheelchair and without a caregiver, you need space in old age to move safely, but certainly no narrow spots.
My parents built a new house again in their early 50s, purposely so that the house could be divided into 2 separate apartments. But everything there is much larger in size so that it really makes sense in old age. They still occupy both floors in their mid-70s and don’t even dream of separation and living on one floor; by now, they would rather install a stairlift. What I want to say is: you can’t plan for all eventualities, who knows what will happen then. You want a house now, it should and must fit now, and affordability is part of that.
You also don’t have to have a finished plan drawn up by this company to then inquire with others; another company has different floor plan ideas, perhaps even better ones. Of course, it’s a different matter if you hire an independent architect and refine the floor plan with them until you have the perfect layout for you, and then approach the general contractors with it.
