Google this search phrase for images of how it is usually done (and design ideas) - images for round window in brick wall

You need the round frame around the window - can be metal if desired, but usually brick end-laid in a circle to reinforce the window opening just like arch stones work in a bridge - then the window is put into the brick rough opening like in any other wall. Of course, the required window rough opening size should be available to the Masonry contractor doing the opening, so the window fits right when installed by the Window contractor. Also, details of the flashing and brick weep holes need to be worked out between the two contractors to coordinate the waterproofing around the window unit. For this reason, it is commonly advised to use a General Contractor for the job - to handle any wall framing issues and interior finishes and trim and such (and maybe the window installation too), and generally subcontrators for the Masonry and maybe Window work, depending on the GC's in-house capabilities. The GC is also responsible for the work order and seeing that you do not have an open wall opening that rain (or birds or theives or such) can get in bedfore the window goes in.

Cost for the opening (not including window and any interior trim or such) depends on whether solid brick construction or just brick facade, whether there is any unusual feature like a column or overlying supporting load bearing support from an upper level window or door or such, but generally in a plain brick wall without complications a Masonry contractor can create the opening for about $$500-800 ballpark in normal cost areas - more and sometimes much on work above second story (I have seen to run well over $5000 for a 3' diameter round opening about 15 stories up because there were no good roof connections for a work stage, so the work had to be done from a crane and bucket, with underlying sidewalk overhead protection, traffic control around the crane, etc.). If a wood-frame wall with brick facade, masonry cost is similar but GC will have an additional few hudnred $ doing the framing roughout - normally after the brick work is done.

Masonry contractor would have to look at the wall first too - especially for large openings (over about 3-4 feet) if the wall brick is in poor condition he may refuse on the grounds the wall might start to collapse as soon as it is cut into but before the supporting brick ring can be started. Especially for large openings like this, if the existing brick is in poor shape, sometimes a section has to be rebuilt first to provide a stable wall section, building the opening into the new wall section as he goes. (Normally in buildings well over a half century to better part of a century old or more).


If this stained glass round window is going right above the door, your contractor may well decide it is easier and cheaper to install it as part of the door installation - with the main load-bearing "header" carrying the wall load around the door opening being located above the round window rather than right above the door like it wouldnormally be, so the round window just gets framed in normally. Then brick facade would be built up from the door header (which could be less "deep" than normal in this case) to the main header above the window. This solution can also give you a lot more architectural design options around the window, because the wall section around the window and vertically between the door heqder and the main header above the window would be non-load bearing - so can be brick, stone, textured or plain panelled, etc - whatever architectural finish you want.
