Ice Factory, Grantfield, Lerwick

The Ice Factory in Grantfield, Lerwick, is an early 19th-century pair of two-storey and attic industrial buildings that share a side wall, creating M-gables on the east and west sides. There are also single-storey gabled buildings that project to the west. The walls are made of random rubble with dressed sandstone accents, which are smoothed at the edges.

On the east elevation, the M-gable features openings with segmental-arched lintels, with the left gable having a hoist projecting from the gablehead. The right gable has a wide opening with modern doors at ground level and an infilled door to the left. There is a partially infilled loading door at the first floor, flanked by windows, and a vertically-boarded timber loading door with a timber flagpole above it in the gablehead.

The north elevation has an asymmetrical and irregular arrangement of windows. There is a chimney-gable to the left of centre, with windows on either side. The right window is shared with a group to the right, which is centred by a four-panel timber door with a plate glass fanlight, accompanied by a matching window to the right. Access to the door is via an open timber stair leading to a landing supported by decorative cast-iron brackets. Below the chimney-gable at ground level, there is an infilled door, with a boarded window to the left and a six-pane fixed-light window to the right.

The west elevation features gabled cement-rendered rubble wings that project at ground level, with built-up wallheads. The south elevation consists of two widely spaced bays, with windows flanking the centre at the first floor. There is a modern lean-to addition projecting at ground level to the outer left.

The principal windows on the first floor are 12-pane timber sash and case windows, and there are vertically-boarded timber doors. The north block has purple-grey slate roofing, a cement-rendered rubble and brick chimney, and ashlar skew copes. The south block is finished with grey slate and corrugated-iron cladding.
