“Thanks to the phenomenal work of Gary and his team, our classroom was open in incredible time – a very speedy turnaround. The classroom itself is unlike the prefabs of old, it’s a truly modern modular building. Castle cabin streamlined the process as best they could and guided me along the way. In the midst of a global pandemic we managed to open our new class on time. Any bumps in the road were dealt with efficiently and to our satisfaction and no request was too big for them. Would whole heartedly recommend dealing with Castlecabin.” 

Kevin Twoomey, St. John's National School, Shannon, Co. Clare
