ᐅ Building on a backlot. Where would you place a structure, and what type of building would you choose?

GeraldGHello everyone,
Due to the recent “building boost,” a friend might have the opportunity to build in her parents’ garden. The area used to be a mixed-use zone (hence the halls attached to the houses), but now the plot is apparently designated purely as residential.
The parents’ house is on plot 1403. The plot is about 31m (100 feet) wide, and the shorter side of the longer edge measures roughly 61m (200 feet). The shortest distance from the house to the main road is about 38m (125 feet). Plot 1401 belongs to the grandmother. House number 5 on plot 1404 are just neighbors.
The marked main road is a busy country road, and the image is oriented north. The plot is relatively flat, rising slightly (less than 1m per 10m, or less than 1 foot per 33 feet) towards the west.
The local council has generally indicated willingness to allow additional infill development here but would expect a preliminary building inquiry for further processing. She is currently still considering whether it makes sense to build there at all. Her parents would demolish the small hall to provide access for her. Even if it doesn’t fit visually in the best way, she would like to build a town villa. Two stories are permitted.
How would you plan the house (rather square, let’s say 10 x 10 m² (33 x 33 ft²)) with parking space and garden here? Currently, she “fears” that the main road will be quite disturbing (does anyone have experience with how well this can be mitigated?), that her parents’ garden is too small and shaded, or that it would be too close to neighbor house number 5. House number 5, by the way, is about 11 x 11 m² (36 x 36 ft²) from above (including the roof), roughly the size she wants to build.

From which side is the house/plot supposed to be accessed and connected? Through your parents' property? Has that been clarified?
I see a potential issue obtaining a permit via the public road, as there may be no utilities available there and, for example, traffic flow could be disrupted in a 70 km/h (45 mph) zone.
For questions like these, I would recommend bringing an architect on board who can then also handle the preliminary building application.

Green driveway,
Orange existing garage???

Red imaginary building line.
It would be best if the girlfriend registers here herself. Handling this indirectly through several people is no fun.

This must be taken into account in the specifications. Use soundproof windows with a rating of Class 4, and if possible, carefully plan windows facing the street. Install a controlled mechanical ventilation system and choose an appropriate wall construction. (There are wall constructions that provide good sound insulation, and others that are quite noisy.)
My experience: We have a heavily trafficked federal road 200m (220 yards) south of us and a fairly busy country road 100m (110 yards) east of us. Currently, only the shell of the building is complete – inside it is completely quiet as long as the windows are closed. However, the situation for the property in question is significantly closer to the roads than ours!
Noise levels in the garden can already be noticed currently.
