The flats had two different designs, the more common being with the lift on the opposite side of the stairwell, Balbutcher and Shangan were the only ones to contain just this design. Balcurris contained one of the alternative blocks, Sillogue (pictured) had two of the alternative blocks and three of the other blocks, three of the four Coultry blocks were made contained the lift on the side of the stairwell. Balcurris was the only row of flats to have its blocks separated by a road, the latter three blocks faced a different direction to the first two blocks and were the most visible from Dublin Airport.
