ᐅ Possible Building Area / Living Space

Good morning,

I am planning to purchase a plot of about 770 sqm (8,293 sq ft) and have a question regarding possible development.

Floor area ratio: 0.6
Site coverage ratio: 0.35

As far as I understand, this allows for 460 sqm (4,951 sq ft) of living space. Does this area also include basement rooms, garage, staircases, etc.?

Attached is an excerpt from the development plan.

Thank you.

If it is a full story, basements and attics are also included. Stairwells are always included; for partial stories, you have already quoted the relevant rules. Terraces, balconies, garages, etc., are not included unless local regulations specify otherwise.

But you haven’t actually read the text in the photo (state building code), have you? It also covers non-full stories as well as the enclosing of rooms and staircases. I would include all floor area. And the architect is the one who knows exactly.

Yes, I have. It only refers to rooms located in non-full stories. So, it’s an addition to the “standard” regulation, as I explained in my post.

Thank you for your answers. So, if I were to convert the roof, which is not a full upper floor, into living space, would the area then have to be included in the calculation?

The site coverage ratio is generally more interesting in terms of how much it can be exceeded if driveway areas, etc., are included. In the specific case of an actual building footprint of 269m² (2890 ft²) and a total floor area of 462m² (4970 ft²), I clearly see that a comfortably sized house is possible without getting too technical or using tricks—unless, of course, the seventh child is not going to be the last.
