Unless things have dramatically changed in the last 2 years, I bought a site in early april 2005 with OPP and had full PP by 31st july 2005. We used Cash Powell based in Wexford and found them extremely good. From day one when he looked at the site, we showed him a series of style of house we were thinking about and he put us in the right direction as to what would and what wouldn't be allowed. BTW the site is roughly halfway between Ballygarret and Kilmuckridge, and would be termed as Gorey area.
Best of luck
