I have a gambrel that I would like to add two dog house dormers to. The house is 28’x40′. The lower roof pitch is a 21 while the upper roof pitch is a 3/4. What would be a good size for the dormer(s) such that it would not over power, or look too small, compared to the rest of the house? How about the pitch of the roof of the dormer? I want the trim from the dormer to match that of the gambrel (transition). Oh yeah, what about using radiant heat for some 3/4″ birch flooring from Mirage? Thank you all in advance. Handyboy

Kinda hard to tell you something that subjective without having any idea how your house looks.
And what's a 3/4 pitch?
You might get some useful responses if you post a picture or 2.......

Dormers look best when spaced evenly.So when you look at the roof the dormers don't look squezed together or are to far apart.
Your language is confusing.
I can't imagine how one would place a "doghouse dormer" atop a gambrel.
The kind of dormer you mention sits on a roof. A gambrel requires that any dormer be worked into it.
The pitch should be gambrel in the same pitches as the existing or it should be a shed dormer which is more common in gambrels, the upper pitch extending to just above the window on the same plane.
I assume a 3/4 pich to be a 9/12
I made the mistake of writing 3/4 when I ment 3, or 4 as in pitch. It is probably closer to a 3-1/2 pitch while the other pitch is about a 21. So the pitch of the lower roof on my gambrel is about a 21. The pitch on the upper roof is 5 and the pitch on the sded dormer on the back of the house is about a 3-1/2. I guess the style is a queen ann with the basic outline of the gambrel. The dormer that I wish to add to the front of the house would have a single gable roof line that I wish to blend into the upper roof which is a 5 pitch. When I become better at this I'll attach a picture.
I guess I was asking about a rule of thumb for the dormers. Should the pitch of the dormer match that of the upper roof, because that is where they will merge?
Thanks again for (all of) your help. Turtle/handy boy
