DIY dormer window renovation by installing a windowsill, by Marthijn

Description

After having a dormer window installed, we made a neat wall. After this was ready, it was time for a handsome windowsill.

I had the dormer window installed, and I installed the wall and windowsill myself. Of course, I had the windowsill cut to size by TOSIZE.dk.
Because I did not want the windowsill to extend too much, it had to be sawn to size (35.0 cm wide). Most window sills were 30.0 cm or 40.0 cm. 30.0 cm was too narrow and I thought 40.0 cm crossed too far. 35.0 cm was therefore a nice size. I was able to indicate this immediately via TOSIZE.dk, as well as the finish. Super organized.
