A few nice Aluminium Windows images I found:
Tottenham Stone Clad 2009

A 1920s gem, even better for the thick use of yellow in addition to the more usual dark red and grey. One of my favourites, with interestingly angled garden path. The wall looks original. Aluminium window and door frames complete the confection.

No original brickwork survives in this photo. And only one house retains the fine sash windows from the mid 1890s I guess. Roof turrets have also been shaved off as slate roofs have been replaced on a budget. The context produces a rather mundane clad houseeee with highly inappropriate aluminium window frames and historically ignorant openings.
