More than the typical project that makes it here, this one needs to be explored in PLAN view. Because of the angles and tight photographic conditions, perspective drawings can be misleading. Ideas about paving and planting would be much more clear, and complete, in plan view. For that, you'd need to start with a base plan that shows all the existing features that would remain, and none that are subject to changing. Meanwhile... I would get rid of the trim and shelf around the garage and the Tudor trim and shelf at the back part of the house.

With the first photo, I like the size of this porch. With the second photo, I like the materials and style but would prefer for the sides to be closed off for safety purposes. With the last photo, I like style. But I suppose the original point was I wanted an access point from the driveway for inclement weather. As well as a new pathway to the front door. Plus, that’s what he originally wanted to do, make a porch. Now his idea has changed and naturally I have to go alongside that thinking. You know, cause we have to work as a team.

100% an architect. A builder will make the design plan a reality, but you need to come up with the design first.

Find a window that is near the size of those in the dormers. It also needs to match the number of panes (6) in the dormer windows. You don't need to mirror the dormers only the windows in them. You need a carpenter to cut a hole in the garage gable for the window, then place framing for the window on the interior of the cutout. The window is put in place, secured and trim to match the rest of the house is cut and fitted to the outside. Adding a vent uses the same cut and frame, but doesn't require matching other features unless you have other gable vents that you wish to match. Vents are made in square, rectangular, triangular, round, half round, arched and octagonal shapes. They should have metal screen or hardware cloth on the inside to keep small birds and such from getting into attic space. This can be added if not part of the vent as sold.
