ᐅ Floor plan design for 4 people, building volume predetermined

Hello everyone,

We are a family of four (children aged 4 and 13) and have been trying since 2017 to obtain a building permit for a plot of land owned by my parents, located south of Potsdam.

The main challenge is the location of the property. Since my parents’ house is the last house on the street, the residential area also ends there, and despite having 10 hectares (25 acres) of land, our building options are extremely limited. After a long legal dispute, we have at least secured a preliminary approval for a building permit. However, this comes with the compromise that the new building must be constructed on the current site of an old barn (key point: model effect when building in rural areas) and must adhere to the barn’s existing volume. We need to demolish the barn and then build our new home on that spot, which means we have very strict requirements for the floor plan.

We have had an official site plan prepared. Since our original plan (an L-shaped bungalow) was basically the opposite of the current planning, I would be very grateful for any advice on room layout and orientation, as I have not found a good approach so far. The barn’s footprint can only be shifted along the axis to the extent that the property boundaries do not overlap. According to the building authority, a wall thickness of 25 cm (10 inches) is allowed as an increase in volume, but any further enlargement (bay windows, altered roof pitch, etc.) is not permitted. Our equity amounts to around 250,000 €.

We already have a planning meeting scheduled with an architect (March 1, 2023), but it would be great to get some ideas here on what we should consider beforehand. Perhaps someone has similar dimensions and ideas on how to create a nice floor plan.

Zoning/Restrictions
Plot size: Currently not fixed. Between 2,000 and 3,000 m² (22,000 and 32,000 sq ft), but the buildable area is fixed.
Slope: No

Basement, floors: No basement
Number of occupants, ages: 4, two adults and two children (4 and 13 years)
Room requirements on ground floor and upper floor: Predefined

Other wishes / special features / daily routines, including reasons why certain things should or should not be included

Thank you very much

So am I correct in assuming that the new house must not exceed the exterior dimensions of 8.19 meters by 10.60 meters (27 feet by 35 feet)? Is the map oriented to true north?

And where and how do you access the plot? Where could parking spaces possibly be located?

Exactly, and yes, it is oriented to north.

What is the roof pitch? 45° (45°F)
The information here is a bit sparse. 😉

Parking spaces are already available, and we are already living on the property, although still very cramped in the parents' house.
