ᐅ Floor plan of an accessible bungalow

In the end, we can talk a lot here.
Go to your construction company and ask for a reasonable quote for a custom bungalow with all the extras you mentioned here. The floor plan is secondary for now. You can easily adjust that in the bungalow.
Once you have the quote, we can meet here again. I would actually claim that you will exceed your budget.

- barrier-free main and secondary entrances
- accessible bathroom with a height-adjustable second sink
- staircase to the attic
- attic prepared for finishing (?)
- bungalow size suitable for 4 to 5 people with spacious walkways
- work nook or office
- barrier-free terrace exit in the living room and possibly also in the children’s room

I will skip the staircase and the drywall installation. For a second child, there is a kids' room. If a third child comes, we will forgo the home office. You can't predict everything (according to our plan, we should already be expecting a third child, but we are still occupied with our first).
Let's see, I will probably receive a new plan next week.

So you are sticking to the design of the angled bungalow that you initially received from the builder, even though the accessibility is questionable? Am I correct in assuming that a discussion on this topic would be pointless? At least I’m glad that you are focusing on your existing child for now, rather than already mentally planning for more without being able to provide them with space.

Why despair when there are established standards and regulations in place?
“For space requirements and maneuvering areas without change of direction, DIN 18040-1 and DIN 18040-2 specify a minimum of 120 cm (47 inches). For the turning space needed by a wheelchair, 150 cm x 150 cm (59 inches x 59 inches) is required. For other users, such as those with a walker, 120 cm x 120 cm (47 inches x 47 inches) should be sufficient.”
Isn’t it better, instead of relying on a visual comparison with other rooms and a subjective feel, to refer more concretely to already existing regulations?

@zizzi .. no one here means any harm, but you are probably about to spend the largest amount of money of your life all at once. You seem to be a lively family since you are planning to have more children. Therefore, you should design this expense so that it fits your life plan for many years and not just rush into signing a contract now.

Sometimes you need a few days’ break from a forum like this to reflect on what has been said and to see if a better, more sensible plan emerges.

What I and others here provide as sketches are not meant to be final solutions, but rather to show you what else might be possible.
------------------------
To summarize:

• Side entrance accessible for people with disabilities means this utility room must have a passageway at least 150 cm (60 inches) wide to remain accessible, and the entrances and exits of the utility room need to be wheelchair-friendly. This will increase the floor area required. Usually, houses are raised slightly above the outdoor ground level … I don’t know how you want to handle this at the carport.
• Your wish includes one wheelchair-accessible children’s bedroom, one children’s bedroom, one office, one master bedroom, utility room with accessible access, bathroom, toilet, living room, dining area, and kitchen all on one floor.
• I’m not sure what you mean by a square living area, but I consider it practical, especially when planning for more than one child, to separate the living area from the dining/kitchen area somewhat. Teenagers have visitors, want to cook or do other things. As parents, you might want to retreat a bit. Even without the parental aspect, it’s possible that a man and two friends watch football while a woman and two friends quietly have coffee and chat.
• By the way, square areas between 5.5 x 5.5 m (18 x 18 feet) and 7 x 7 m (23 x 23 feet) combining living/dining/kitchen generally do not subdivide nicely. Instead, they tend to create three separate “use corners” in the room, which look more like furniture showrooms with separate setups next to each other.
• Terrace access from the wheelchair bedroom means a second wheelchair-accessible terrace door (thresholds). Wouldn’t it be simpler to make the path from the wheelchair bedroom to the main terrace access as straight as possible? (See my plan).
• The current cost estimate is, in my opinion, missing many items and therefore costs; here are just a few examples:
• Wheelchair-accessible design of entrance doors
• Wheelchair-accessible terrace access
• General clarification of electrical outlets and other costs
• Good idea to finally plan for roof access.

Bathroom and second sink ... okay, it should probably be height-adjustable and wheelchair accessible. You could still reconsider the washer/dryer placement, possibly even create space in the hallway. But that is detail planning.

I’m afraid the bathroom planned by the builder won’t fit a second sink because there might be too little space beside the toilet. Also, you will always have a wet area in front of the toilet when someone has showered, etc. To me, the builder’s bathroom layout does not work well as both an accessible bathroom and a family bathroom at the same time.

In general, I recommend furnishing all rooms to scale with furniture of real sizes. In the living/dining/kitchen area of the builder’s floor plan, for example, the table stands out at about 120 x 80 cm (47 x 31 inches). Where will the TV go in the sofa area?

Overall, I think 130 m² (1,400 sq ft) will not be enough since the builder’s offer already shows 138 m² (1,485 sq ft).

-----------------
And here’s something to consider: in my plan, you criticize that the parents’ area isn’t private enough, but in the builder’s plan, child 2 can always get to the bathroom directly from the front door and also isn’t really private.

And if you are planning really for child 2 and 3 and home tax consulting is to be done from there, I would at least design the plan so that the house could be expanded upstairs.

------------------
Placing technical systems under the roof may be a bit more expensive but allows more space on the ground floor. Costs can also be saved in other ways — for example, by avoiding bay windows, by a gable roof (@zizzi ... what does the development plan say about gable roofs and what pitch is allowed?), by reducing the building footprint, etc.
I copied the following from the note about the development plan in post 24:

@everyone ... The building envelope looks good … can anyone see if only hipped roofs are allowed or if other roof types are permitted?

I could also imagine a house with a long south-facing side and narrower east/west sides. That would also create space for the carport.

@zizzi, regulations are one thing, and they generally set minimum standards. It makes more sense to approach the layout from a practical perspective since every corner adds extra effort and may not always be perfectly precise. Therefore, planning straight routes is advisable.

Compare the route from Bedroom 1 to the kitchen in both plans ... just as an example.
