Most Irish football grounds, of any code, were formed of earth embankments cast with rough concrete terraces, and stand roofs were usually just versions of agricultural structures, there wouldn't have been much design input I imagine. I think the corrugated shelter at one end of Richmond Park [ - The Stadium of Light - ] is still called 'The Shed'.
Handball alleys would have been every bit as undesigned, but more interesting from a scale and often a streetscape point of view.
I recall a great little cartoon in L'Ã©quipe around the time that Ireland beat France 1 - nill [with a Liam Brady goal] in a world cup qualifier [when they had the likes of Platini and Rocheteau etc.], depicting the French rugby coach [some pocket-sized Nepoleonic type] who had just master minded beating us in rugby - again - a week or so later at the same venue. The rugby coach is shown taking the soccer coach by the hand and bringing him down to Lansdowne Road with the caption 'I'll show you how it's done' - or something similar in French. Lansdowne Road was rather accurately depicted as a miserable little recangular arena with two unequal shed roofs facing each other. This would have been at the time that France had developed the new Parc des Princes stadium, predecessor to the even more magnificent Stad Francais.
p.s. the cartoon must have been reprinted in the Irish Times, one doesn't buy L'Ã©quipe after a large French win.
