Hello everyone,

The floor plan was entirely designed by me. Unfortunately, the construction company does not have a qualified architect, so I would like to have it reviewed here:

Development Plan/Restrictions
Plot size 1644m2 (1,7697 sq yd)
Slope yes (6m (20 ft) height difference bottom/top, 1.5m (5 ft) right/left)
Site coverage ratio 0.4
Floor area ratio 0.8
Building envelope, building line, and boundary lines cannot be followed, otherwise construction is not possible
Edge development
Number of parking spaces
Maximum number of floors 2
Roof shape 42-46
Style
Orientation
Maximum height/limits

Homeowners’ Requirements
Style, roof shape, building type bungalow
Basement, floors no basement, 1 level
Number of occupants, age 2 persons, 46/55 years
Space requirements on ground floor, upper floor 130m2 (1,399 sq ft)
Office: family use or home office? Office later room for caregiver as no children, therefore opposite guest WC with shower for caregiver if needed

Open kitchen, cooking island no
Number of dining seats 4-6
Fireplace wood stove
Music/stereo wall no
Balcony, roof terrace terrace
Garage, carport garage with storage room

Additional wishes/special features/daily routine, also reasons why certain features are included or excluded Single level, already prepared for accessibility

House Design
Designed by: Do it yourself
What do you especially like? Why? One level, age-appropriate
What don’t you like? Why? Huge hallway
Cost estimate according to architect/planner: 455,000 including paving and terrace
Personal price limit for the house, including fittings:
Preferred heating system: no choice, therefore air heat pump

If you have to give up something, which details/extensions
- can you give up: area if better planning is possible
- cannot give up: bungalow, garage access, pantry

Why is the design the way it is now? For example:
The basis was a design from the construction company. Revised with orientation of living spaces etc., it came to this result

Thanks haydee and wiltshire for your constructive comments. I will take your remarks into account and bring in an independent architect to review the bathroom design again, especially considering the zero-barrier principle!
Saying there is no qualified architect was not meant as a judgment but should be taken literally. There is a draftsman but no architect.
However, being judgmental is a major issue here, as I have noticed. Therefore, I will close my inquiry here.

It’s not just the bathroom. You need space everywhere. I only realized this last week—maneuvering a wheelchair between the entrance and cloakroom, plus helping to put on and take off jackets. It can’t be any tighter. The bedroom is also important. It doesn’t have to be a wheelchair—the 100cm (39-inch) doors are also practical for crutches, and oxygen tanks require space, too. The good news is you can now design the floor plan around the wheelchair without making the house look like a hospital or nursing home. In almost eight years, only two people have noticed that we accounted for the standard requirements. A compass is your friend to mark and check turning circles.

Our architect told us 6 years ago that everywhere a 1m (3 ft) sphere must be able to pass through; this already makes a big difference for accessibility. The doors are 1m (3 ft) wide and 2.1m (7 ft) high, so it doesn’t look too much like a hospital. One of our visitors, who is a paramedic by profession, noticed this.
