Four brick-making sites were uncovered next to natural clay pits on the Lake Innes Estate. One was located beside the lake, opposite the house, while the other three were on the periphery of the estate settlement, closer to where they were needed. Two types of bricks were found at these sites: plain bricks and bricks stamped with an ‘I’. Three of the sites had remains of brick clamps — large brick structures in which bricks were fired. A secondary account of early brick-making at Lake Innes suggests that bricks were made by convicts.
