Builder's houses often simply feature too many materials and giz-mos, and that's the case here. Your design suffers from all the lipstick and mascara applied to the front facade, with very different, cheaper treatment on the remaining three facades. Even the roof pitch is different in front from the side and rear. The elevations look like two different houses--one for the front elevation, and another house for the remaining elevations.

You really don't need all the decorative items such as shutters and fake exterior gable trusses.

In fact, you really don't need the stick-on rock on the front facade, since it isn't used on any other facade.

And...the same applies to the different materials used in various upper gable walls.

My recommendation is to simplify and unify.

The architectural formality of the front is totally absent on the side. You need to fix that amateurish mistake before choosing cladding. This kind of design problem is often solved with less formal materials. This one cries out for cedar shingles on all sides or a complete redesign.

The front dormer doesn't appear to have the ceiling height required for a habitable room; it is just for show?

The drawings seem to indicate the ceilings are 9 ft but it doesn't matter since I assume the front dormer is a clearstory monitor in the roof of the living space and doesn't require headroom.

I always draw at least one section through such spaces to be sure they work well. You should do that.

You should also draw a perspective to be sure you know what the house will look like. Perspective visions guarantees a house can never look like the elevation drawings.

I suspect you might find that raising the ridge of the side gable would help to establish it as the main form of the house with gables extending to the front and rear. That seems muddled in the current version. In any event, that roof needs a steeper pitch.

Good recommendations from @Virgil. Simplify!

- My first recommendation would be a single cladding all around. Two at most.

- Too many different roof pitches.

- Do you have neighbors on either side? Or behind? If so then do the sides and back to the same finish as the front - why should your new neighbors have to look at cheap siding for hours every day while you give someone who drives by in front for 3 seconds a much nicer bit to look at?
