Barrier-free guide

It's not about making the house wheelchair accessible, but about considering the space requirements. It's pretty much the same for a walker.

The extension is missing measurements
Turning circle approx. 1.5 m (a compass helps)
Space between bed and wall/wardrobe 1.5 m
Doors 1 m

Your parents are building new now. Your mother has a handicap, I wouldn't make compromises there. In addition, there are the typical age-related ailments.

Entrance without thresholds, hallway area without shoes and bags on the floor (trip hazards). Seating area to change shoes

Bathroom without niches, with turning circle.
When age hits in 10, 15 years, you might not want to walk backwards into the shower and on the wet floor anymore

Hanse Haus Bungalow 133
Is too big and does not fit.
However, bathroom, sleeping area, and living area really work

I would design the intermediate building so that it serves as an entrance for your parents and accommodates the wardrobe.

Long narrow hallway gone
Mini storage room gone
All doors 1 m wide
Bathroom truly barrier-free except for the sink
With timber framing and front buildings, have the wall where handles etc. are mounted or might be needed in the future, reinforced with solid wood

Do you already have any views so far? Old ones are also okay.

Are you sure you have the right construction partner?

The floor plan just doesn't fit at all. Neither for the grandparents nor for you.

Just the practice alone.
Have you ever set it up?
On paper to scale?
What if a patient has to wait and can't enter the room?
What if the patient needs to use the toilet?

The waiting area will be in the passage between the houses. More than a small bench is not needed there. And the patients use the guest toilet in our house. The practice is sufficient in size. The one I currently work in isn’t any bigger either

And why can't you put ventilation there and provide ceiling outlets? That would be even easier than with solid construction.

Ah, access now also goes through this intermediate structure. I would have overlooked that. The whole thing is not cohesive. So many small things that are suboptimal. Where are the parking spaces, trash bins planned?
