Hello,
I am planning to build a small dormer (homeja) extending from my roof (1 1/2 story house) with an 80 cm wide half-moon window at the end. The upper floor is unfinished, so I have access to everything I need.
I have not found any type of construction description for this on the internet - actually barely any information at all, so I am grateful for tips, ideas, photos... anything that can help me get started.
Thankful for any response.

Doesn't sound too difficult, since having windows of 80 cm is within the trusses. If you need to place the window where a truss goes, it would require much more work with reinforcement, but in this case, it is not relevant.
The actual construction doesn't seem too complicated. The tip is to make a "mini" truss above the window (alternatively with small rafters, if you want a vaulted interior). These are reinforced downwards toward the wall (floor) which then supports the construction. The easiest way to achieve the rounding on the roof of it is to use a roof panel that bends around. Just remember to space for a small air gap.

Actually, it is Northern Europe's easiest project... SBF 05 applies as usual...
It might take a while if you're not used to constructing roof dormers, which isn't the most common task you'll encounter. This applies to both professionals and DIY enthusiasts. The amount of work is determined by the height and width of the dormer. In your case, the external dimensions will be around 120 cm... You can prefabricate before opening up the roof... The pie-shaped pieces on the sides and the rafters... The rafters can be made in two ways... An arch at the front that in turn supports running planks. Or in the form of 3 arches like traditional rafters... The latter is preferable if you plan to panel the inside of the dormer... and it also makes the boarding on the outside relatively simple... Since running planks require bending the decking boards, which is quite unappealing Masonite isn't a good choice if you intend to clad the dormer with metal, which is preferable for rounded constructions.
