Hello everyone,

we are currently planning roof windows. Below you will find the attic floor plan, where the windows have been placed provisionally:


Upper floor plan with roof terrace, staircase, and living area

As you can see, there are also windows on the gable side. The roof space will be used as a studio and has no other interior walls.

Are 6 roof windows too many? Maybe you have some experience with this.

Then please go ahead and draw in the walls, doors, and furniture.

He already stated that there will be no walls, so there won’t be any doors either.

If the gable windows are not going to be made larger (I personally think interior functionality is more important than the exterior appearance), I would definitely recommend installing the six windows. The room is over 70 m² (750 sq ft), so that’s actually quite few.

How large should the roof windows be? There are also really cool double window options or even these standing balconies... Maybe two wider/larger ones per side could also be an option? Personally, I find those tiny roof windows on big roofs a bit lost, and yet it still tends to be darker inside than you would expect from so many windows...

Just installing 6 windows without reason doesn’t make sense.

Basically, we are talking about hypothetical scenarios here: you can tell from the punctuation that the positions of the roof windows are merely possible suggestions on how it could (or should?) be done.

So if you don’t want them, you might not get the elements shown in the plans.

However, they are not entirely unreasonable: a studio in a house can be a one-room apartment, meaning a space with multiple functions. From that perspective, I find the roof windows to separate different living areas, which you would need to divide, quite sensible.

Use: attic studio (children’s play area, additional office, TV room, etc.)

It’s stated here as well. If you want to define separate zones, those areas need natural light.
But not only then:

If the room stays as planned and is used as living space, that is, a common room, then you have to say: they are definitely _not_ too many!
A 90m² (970 sq ft) living area requires a certain amount of window surface.
If you also consider the length of the house/room and the rather dark roof slopes, you need correspondingly more window area. (I have removed my previous numbers of 7.2m² and 9m² (78 sq ft and 97 sq ft) here since the sloped ceiling reduces the usable space, but it also doesn’t make the room any brighter.)
So with these windows, you don’t get an instant “Oh, how bright!” effect. It’s simply necessary to illuminate the space, plainly put.
From this perspective, the architect has done a professional job in the design.
If the budget allows, I would fully glaze the gable ends and place two roof windows in the middle. If not, then don’t call it a studio but rather an converted attic.
Even then, having 6 larger roof windows is perfectly reasonable.

A 90-square-meter (970-square-foot) living area requires a certain amount of window surface.
Considering the length of the house/room and the rather dark sloping ceilings typical of attics, a correspondingly larger window area is necessary. (I deleted my previous figures of 7.2sqm and 9sqm because the sloping ceilings make the room smaller, but also don’t make it brighter.)
So, with these windows there is no “oh, how nice and bright” effect yet. It’s simply necessary to illuminate the room, stated plainly.
In that respect, the architect has already done a good professional job by marking them on the plans.
If money is available, I would fully glaze the gable walls and place two roof windows in the middle. If not, then don’t call it a studio but rather a converted attic.
In that case, I would gladly have six larger roof windows.

However, I would also reconsider photovoltaic panels. Therefore, it might be worth considering gable glazing and fewer roof windows.

Yes, we are doing that at the same time. Hence the question about the number of roof windows.
