Hello community,
I have a terrace roof covering about 45m² (480 sq ft).
For this, I have a building permit including structural calculations, etc.
Now I am planning to glaze part of the terrace and convert it into a kind of conservatory. The room is intended to be used as a "cold room," and the glazing area would remain under 75m³ (2,650 cu ft). My question is, do I need an additional building permit or planning permission for this in NRW?
Does anyone have information on this?

Okay, we are reconsidering installing some roof windows.
Can I ask again how the gross floor area (GFA) is calculated? Does it include only the exterior walls or also roof overhangs, gutters, etc.? As far as I know: roof overhangs are only counted if they are significant. You can’t extend the roof by two meters to create an additional sheltered seating area. Exterior walls definitely count.
Regarding boundary construction: I’m asking for a response on this, as it could change everything!
Otherwise, you don’t actually want to build a conservatory but just use that term for your project? What exactly is the intended use you have in mind?

Otherwise, you don’t actually want to build a conservatory but just use that designation for your project? What exact purpose do you have in mind? Actually, I want to create a space where I can occasionally eat. There will be a table inside. I also want to be able to look out into the garden and so on.
I would like the designation “conservatory” because then it would be exempt from permits provided I install roof windows. Since the room won’t have heating, I plan to close the door to the house in winter and use the space as storage for garden furniture. In summer, it would be used for relaxing, as mentioned.
Since the roof covering is already approved, the idea was simply to enclose it with panoramic windows, insulate the roof and the non-glazed wall surfaces, and render the exterior.
