Phases of Construction Adamstown is Ireland’s first Strategic Development Zone which means that the construction of homes runs in tandem with such facilities. There were 13 phases of development, each with certain restrictions. This was to ensure that certain infrastructure was in place for the residents and controls the development of the area. The phasing and implementation policy was sequential rather than periods of time. For example, no more than 1000 residential units were allowed to be built until the construction of the railway station was complete.
