Hello dear forum,
We are currently planning the development of the plot of land attached. The previous owner’s initial plan was to build a duplex (see preliminary building inquiry in the attachment). As the new owners, we are now wondering if there might be enough space on the property to build two single-family houses while complying with the boundary building regulations. The plan is to divide the plot in half and possibly build two single-family houses. However, this could be quite challenging due to the building boundary limits.
Are there any exceptions regarding boundary construction if an agreement on a reduced distance is reached with the future neighbor? Or is it generally not allowed to reduce the distance because of fire safety regulations and similar requirements? I have attached the relevant zoning plan provisions (upper information, MI).
Thanks in advance.
Best regards

Under certain conditions, this is indeed possible (for example, building end walls without openings, see §6 LBO_BW), but not recommended (see @11ant). However, I didn’t actually mean completely windowless walls – rather, that the sun shouldn’t cast light at several times of the day like a guillotine (and for that reason alone, the distance to the neighbor shouldn’t be reduced to the narrowest possible light well). Otherwise, having a detached building would come at the cost of gloominess.

So why pay for it with darkness?In the sense that a truly detached building with sufficient spacing would allow better natural lighting.77.willo schrieb:
But it won't be darker in principle than the alternative semi-detached house.Exactly. Lost building width without any gained advantages in lighting.https://www.instagram.com/11antgmxde/
