ᐅ Floor plan of a single-family house with a flat roof on a 600 m² plot of land

Hello everyone,

This year we purchased a plot in a new development area and have been planning our house since then.
We have already revised the preliminary draft from our architect several times, and before we proceed towards obtaining the building permit / planning permission, we would like to gather opinions and suggestions for improvements from this great forum.

Slope: no (however, the land slopes steeply down behind the plot)
Site coverage ratio: 0.35
Floor area ratio
Building envelope, building line, and boundary
Edge development
Number of parking spaces: two per housing unit
Number of stories: max. two full floors
Roof style: free choice

House Design
Planning by: architect (preliminary draft)
Cost estimate according to architect/planner: construction costs approx. 500,000€
Personal budget limit for house including fittings: 600,000€
Preferred heating technology: air-to-water heat pump

If you had to give up, which details/finishes
- could you give up:
- could not give up:

Why is the design the way it is now?, for example:
Which wishes were implemented by the architect?
- individual wishes realized, e.g., as open a ground floor as possible
- since the plot slopes slightly to the north, we wanted a second "level" (we are aware this is not age-friendly). This was implemented in the living room (as shown in the example image). There are also stairs in the garden, and the basement windows correspondingly receive natural light.

What is the most important / fundamental question about the floor plan in 130 characters?
What have we overlooked?
Or, what do you think is not planned sensibly?

Thank you 🙂

Awesome house! At first glance, I would build it exactly like this.

Are there also plans with measurements? Doesn’t the house at the living room corner extend beyond the building boundary, and does the neighbor from 14 drive directly past your garage?

Great floor plan! I would move in right away 😉

The only thing I might reconsider is adding a second shower. The guest bathroom could be a bit larger since, with the existing basement, you could also reduce the size of the storage room.

I like it too 🙂 I’m just not so keen on the master bedroom. If I’m not mistaken (I’m really not sure), then the headboard of the bed with the lettering is there, right? That means the person sleeping by the window can’t pass by the chimney flue? Maybe it would be enough to leave out the door to the hallway there..

I think it’s okay as well.
However, I definitely wouldn’t build it like that and place the garage on the south side of the house, which blocks many necessary windows.
Is there a reason why the garage wasn’t positioned as a boundary wall on the east side, so that there would at least be a south-facing window in the dining area?

By the way: I would move the door to the bathroom closer to the storage room, so that you don’t look directly at the toilet from the dining area. I mean more like mirror the layout of the room.
