ᐅ Attic not suitable for conversion

Hello everyone,

we are building with a construction company that includes an architect. Unfortunately, we are completely dissatisfied with the architect... a total disaster!

That’s why I’m asking here instead of him...
Our plans state "attic not suitable for conversion" – what does that mean exactly?

We actually wanted windows on both sides of the gable wall. However, he did not include them.
We planned to use a space-saving staircase for access. This was not shown in the drawings at all, as if the attic is not accessible at all...

The roof is probably what is called a nail plate truss roof. It is likely more cost-effective but not usable for other purposes.

You should have communicated this, and your architect should have addressed it. PS: You are the clients; the architect must take your requirements into account—make that clear to them.

It is also possible that the extension is not allowed due to the zoning plan. Extension means additional living space, which is not always permitted according to the development plan. Living space must meet certain criteria, such as a second escape route, natural light, and ceiling height. If the ceiling height is already insufficient to convert the attic, then it is not suitable for conversion.

However, I am not sure if I am correct. @tomtom79 might also be right.

Of course, these matters should be discussed: what do you want, and what is feasible. If something is not possible, the architect should explain why and, if necessary, suggest alternatives.

Not entirely correct, because ceiling height and similar factors determine whether there are sufficient “habitable rooms” according to the regional building code. In practice, the space can still be convertible.

However, if the zoning plan already prohibits it, the conversion is not allowed.

In short: ask an architect what this means... and then verify it.

Perhaps this is a true cold roof, with the insulation placed at the collar beam level, and the space-saving staircase cannot be sealed airtight. Therefore, it is not suitable for future expansion from a building physics perspective.

Thank you. I didn't know any better!
