I thought so. It doesn’t work with you either.
The space requirement is similar to a wheelchair. So if you move forward with the thing.
Logically, a person with a walker is much more mobile.
The turning area for a walker is at least 1.2 m x 1.2 m (for comparison wheelchair 1.5 m x 1.5 m)
The DIN standard specifies a clear width of at least 80 cm for doors. If the alignment fits and the walker is of normal width (there are also wider ones) it also works.
Take your first floor plan, you can’t get from the common room to the bathroom with a walker.
The bedroom is too narrow to drive up to the bed with a walker. Often walking backwards or a sideways step is more of a problem and more difficult than a step or 20 steps straight forward. Grab bars next to the toilet (strengthen the front construction accordingly), more space in the shower maybe a medical wheelchair is the safer option than insecurely tiptoeing over a wet floor.
It’s incredible how much space you suddenly need. For example next to the bed the medical wheelchair/walker, then the helper who helps you from the bed to the bathroom, puts on your socks etc.
At the dining table the chair can no longer only be pulled back by 30 cm and you take a seat, no suddenly it has to be turned 90 degrees because sideways no longer works. The 100 cm between wall and table edge is no longer comfortable.
The reality is often much more than what is sold as barrier-free for old age in brochures. Unfortunately the “old” are not uniformly handicapped either, so there is no one solution.
What I meant is please draw the position of the house in the plan and mark your preferred floor plan with a north arrow.
How steep is the slope in the area where it is being built?
Put the child’s and workroom under the roof.
Then move away from the contractor’s construction service description and the QM and move towards your wishes.
How should the kitchen be, what should it include?
How big the dining area?
Which living room furniture?
What distinguishes you from others. Closet space in the bedroom? Shoe collection, train set, sewing table, bookshelves, inherited farmhouse cabinet to show off etc.
Go through your daily routine.
What bothers you about your current living situation, what do you wish for?
Space in the wardrobe for the sports bag etc.
