Hello everyone, my wife and I have reserved a plot of land in a rural village. We are very interested in building there because we come from this region. Now we have taken a closer look at the development plan and find the requirements quite strict. We are currently trying to find a reasonable solution. But first, our requirements: - Living space approx. 150+ square meters (with at least 3 children's rooms) - we would definitely cellar (however, initially not habitable, possibly later 1-2 rooms with sunlight due to slight slope) According to the development plan, the following points are specified: - 1 full floor, site area ratio and floor area ratio 0.2 (our plot has 700 square meters) - Ridge height 6.7 m (The maximum building height is defined as ridge height (RH), the highest point of a building structure. This is measured from the reference height at the ground floor - floor level (single-family house). RH max. = height of the parapet of the flat roof.) - Eaves height 3.5 m (The eaves height (EH) is measured at the highest point of the intersection of the outer wall with the roof surface/flat roof from the specified reference point (single-family house).) - Reference point: Ground floor – floor level (single-family house) All heights of building structures are determined from the single-family house. The ground floor of a building is the floor that is a full floor according to § 20 of the Building Use Ordinance. Excavations and embankments necessary to achieve the chosen ground floor height are permissible. - Roof types: SD/SDv/PD/WD 22° to 30° / FD 0° to ≤ 5° Now we have already considered various points on how we can implement the whole thing – or how we can get the most living space with the lowest additional costs such as bay windows or dormers. Meanwhile, we have settled on a gable roof in order to use at least part of the upper floor sensibly. Do you have any idea if the whole thing would be feasible with a flat roof, for example (unfortunately we have no architectural training and therefore cannot exactly understand what must be fulfilled with a flat roof to build it at 6.7 meters)? We are grateful for any help and support to fulfill our dream! Thank you in advance for your support!!

Yes. As a set-back floor. You are only allowed to build one VG, so upper floors or basements must not meet the guidelines of the VG. Google again for VG for your country (state building regulations), it should then be 2/3 or 3/4 with a room height for living spaces.

Fortunately, there are people who have such training – very likely also in your area. You share your wishes and possibilities with them, and then they gather all the necessary information for a small fee and design a permit-approved house for you that meets as many requirements as possible.

If you first want to ask the design talents here in the forum for suggestions, you have to collect all the necessary information yourself. Then you open a new thread in the subdivision Floor Plan Planning / Site Planning after you have read the first pinned post there, copied the points, and filled them with information. Often it is important for the supporters to know the entire development plan including the complete textual provisions and the public inspection and date when it becomes legally binding, since the definition of eaves, especially for the recessed top floor, and the version of the land use ordinance, which among other things describes the calculation method for the floor area ratio / plot ratio, depend on this. For sloping sites, a site plan with terrain elevation data is also indispensable. It is also helpful to mention the federal state, since not everyone wants to research that first in the user profile.

But what are the requirements for a recessed top floor in BW? I have really searched everywhere here... I have attached a brief sketch (would that be possible like this?)

I believe that it is not allowed because of the eaves height of 3.5 meters. Therefore, I would rather pursue the idea of the gable roof.

The terms are stated in the Landesbauordnung BW §2. However, the Landesbauordnung from the year of the development plan is always important.
