Congrats on the new addition good luck with the building work and a new born!I've had to compromise quite a bit in order to keep a pitched roof at or above 15 degrees, according to the structural engineer larger Velux windows would have required 8" rafters instead of 6". The issue is I don't have the height under the upstairs windows to raise the roof 2" and didn't wish dropping the front 2" either. To lower the whole structure would mean either a step down into the kitchen which the Mrs ruled out or replacement of all existing floors which wasn't viable whilst living in the property with a toddler and a pregnant woman, who btw delivered addition 2 last night a 8 pound 6 baby boy so work is definitely going to slow down now
Could you not have had one or two more windows of the same size?
