Description
Children's Mill or Boat House is a small-scale boat house constructed from brick with a slate roof, featuring tiled cresting and ventilators. It is notable for its use of yellow brick for banding and dressings, which contrasts with the blue and red brick used for the rest of the structure. On the west side, there is an appealing miniature campanile with a pyramidal swept roof and a finial. This campanile includes small rectangular lights at each stage, which are louvred at the top, and a boarded door on the south side.
The gable ends of the building are adorned with scalloped bargeboards. The gable facing the river has a circular louvred opening above a small semicircular arched aperture with a keystone, located at water level. The uphill gable end features a sunken entrance that is accessed by steps down, positioned behind a brick wall with stone coping.
There is an attached brick wall, which is missing coping, that runs north across the stone weir to connect with one of the sluice houses. The interior was not accessible at the time of inspection.
