The Old Manse, 30 Kirkgate And 1 Hill Street, Irvine

The Old Manse, located at 30 Kirkgate and 1 Hill Street in Irvine, was built in 1820 by Robert Johnstone, and it may include earlier materials. This is a symmetrical, two-storey house with an attic and a rectangular plan, featuring three bays and a single-storey pavilion to the west. The building was divided into two properties around the 1970s. It has a rendered exterior with painted ashlar margins, a base course, an eaves band, a cornice, and a blocking course, while the ends are finished in painted ashlar. The roof has dormers.

On the south elevation, there is a central stucco doorpiece with a blocking course and a tablet, with windows above and on each floor of the flanking bays, all featuring plain margins. The centre of the piended roof has two canted dormers. The east elevation has two symmetrical bays with blinded dormers. The north elevation includes later additions at the rear, which feature an external stair leading to the upper flat. The west elevation showcases the gable end of the advanced single-storey pavilion.

Inside, as of 2013, the original room layout remains largely intact, with some simple cornicing visible. The windows are predominantly two-pane replacement timber sash and case, with some non-traditional windows at the rear. The roof is covered with grey slate and has rendered wallhead stacks at the centre of the east and west elevations, along with coped skews and a gablehead stack on the single-storey bay.
