Floor plan of an accessible bungalow

We have an accessible bungalow. You don’t. The hallway alone ruins it. If you want to comfortably maneuver with a wheelchair, then take a "round" hallway and not an elongated one. Since you are not willing to fill out the questionnaire, here are a few questions I need for an idea:

1. Does it have to be a guest bathroom?
2. How severe is your child’s disability? Can they move around the house on their own or do they need a wheelchair for that?
3. Should it be an open or closed kitchen?
4. Does it absolutely have to be expandable upwards?
5. How old are the children?
6. What type of heating would you like? District heating as described in the plan?
7. Do you want a KfW house?
8. Do you need storage space somewhere? For therapy equipment, for example.
9. We really need the building envelope, or you tell us the maximum size the house may have in dimensions.
10. Is there an absolute no-go for you?
11. Do you want to have a fireplace?
12. Are there any special considerations that need to be taken into account regarding the room layout and the disabled child? For example, do the parents need to sleep directly next to the child? Does the child's room need to have a bed for a parent?

You can see that the information you have given is by far not enough to assess your situation and make a reasonable proposal.

No one who has dealt with accessibility planned this. Rudimentary basic rules of accessibility are being ignored. This is so grossly flawed that it simply cannot be just an oversight.

Well, I actually didn’t want to come at you with that blunt instrument, but rather present an alternative.
But sometimes you have to speak frankly so someone can see that you only mean well when you ask questions [emoji4]

Google barrier-free living space and look at floor plans of bungalows: few square rooms, square hallway, open living, no unnecessary walls and corners. There are hardly more than 3 bedrooms, so no office, but then about 160 sqm living space.
These designs are marked in the rooms with the turning radius of the wheelchair.

I see in your case the utility room upstairs, possibly also a children's room with a shower bathroom. Downstairs on 130 sqm parents, child, bathroom and multipurpose room – whereas the alco room is actually _one_ room without door or wall barriers.
I believe you don’t want to build an officially barrier-free house either, but just some components so that it is affordable for you and provides a more comfortable life for your child?

My view:
Pay attention to 1m wide interior doors. It seems to me that this was not maintained.
The bedroom has too little closet space. Yvonne is right.
For a comfortably walkable attic, 35 degrees roof pitch is sufficient.
Plan the stairs right away. You will never get them so cheap again. (for me 9600,- gross surcharge complete with finished upper floor, with stairs, and small hallway, 1 Velux at the top.
I don’t like the cloakroom wall protruding into the hallway. It makes maneuvering the curve more difficult.
How to lay out the guest toilet if the stairs are included right away, I don’t know. No idea yet.
A concrete ceiling is as superfluous as a goiter on a bungalow. Also unnecessary for a walkable upper floor.
I can tell you: going through this, the stairs and all, was the smartest decision of my last 10 years. The floor is used for drying laundry, (Velux open, standers placed there) saved 500,- on a dryer, it now serves, full of wooden shelves from Hornbach, as an almost inexhaustible storage space for everything, nothing lies around downstairs in the house, everything nicely tidied up, up there it is bone dry, great.

Choose a model house and try to navigate it with a wheelchair. Hanse Haus, for example, has a barrier-free bungalow in Oberleichtersbach, so give that a try. All of you sit down together for a meal at the table or in the living room.

Your floor plan doesn’t work. The hallway, turning circles, helpers, therapy devices, etc.
Take a look at floor plans that are truly barrier-free and compare them with yours.
Ask an association or something for architects who are familiar with the requirements.

I am adding my contribution here (I am mostly on the forum via mobile Tapatalk and there I do not see or find any pinboard where such information was requested).
Are you not confusing this plot and house type with my previous question ( ), there the plot was better in terms of layout but was supplied with district heating and on the south side a multi-family house was planned. That is why I changed it. This plot has not been purchased yet but only reserved.
Plot number: 214
In the offer, the builder considered district heating as the heat supplier (as with the first plot), they will correct it. (I have to plan 7000 € more)
Development plan/restrictions: ris.Stadt-bramsche.de/bi/getfile.php?id=109611&Type=do&
Plot size: 618 sqm (not rectangular, dimensions attached)
Slope: east is lower than west
Site coverage ratio: according to the development plan
Floor area ratio: according to the development plan
Building window, building line and boundary
Edge development: according to the development plan
Number of parking spaces: 2
Number of floors: 1 full floor
Roof type: hipped roof
Style: bungalow - brick facade
Orientation: entrance east, garden west
Maximum height: 8.5 m (all other neighbors may adhere to a maximum height of 8.5m except the neighbor to the west, who may build up to 9.5m high).
Limitations: 3 m distance to neighboring plot
Further requirements: according to the development plan

Owners’ requirements
Style: entrance east
Roof type: hipped roof 35 or 40 degrees
Building type: bungalow
Basement: no
Floors: 1 full floor - attic expandable
Number of persons: 3 (planned future: 5 or 6)
Age: 36, 33, 5
Space requirement on the ground floor: 130 to 140 sqm
Office: family use or home office? YES
Overnight guests per year: 5
Open architecture: yes
Conservative construction: yes
Open kitchen: yes
Kitchen island: depends on planning (maybe)
Number of dining seats: 4 to 6
Fireplace: no
Music/stereo wall: no
Terrace: yes
Double carport with storage room: yes (cars in tandem because the plot width at the street side is 20 m)
Garden: yes
Greenhouse: no
Further:
It must be barrier-free. Our son is severely disabled (due to an accident when he was 2 years old), he cannot walk, cannot speak, but he understands (very smart), he still needs to be pushed in a wheelchair, I do not know if in the future he will manage with an electric wheelchair (hand motor skills are also not good)
House design: attached
Who made the planning: a company that builds houses. (they mostly have their own craftsmen)
Do-it-yourself: maybe I will do the carport and exterior work myself or have it done elsewhere.
Cost estimate according to architect/planner:
170,000 €
Personal price limit for the house, including equipment: 200,000 €
Preferred heating technology: gas heating - Kfw 70 (standard)
If you have to do without, on which details/expansions
- can you do without:
- can you not do without: barrier-free access, 3 bedrooms, 1 study
Standard design from planner? Attached
Which wishes were implemented by the architect? They implemented the kitchen, because instead of one study it was planned.
We would like the attic to be expandable so that in the future (25 or 30 years) a rental apartment can be created (for children not yet here), so the possibility is there.
Therefore, we want a roof pitch of 35 or 40 degrees, knee wall high enough so that the attic can be well expanded. We have initially left out the stairs so that there is a little more space on the ground floor.

I am uploading all the data I have attached.

So far, thank you for your useful tips
