St John's Parish Church And Hall, Church Street, Lochwinnoch

St John's Parish Church and Hall, built between 1806 and 1808, is an irregular octagonal structure made of rubble with ashlar margins. The church features a three-stage square tower with a faceted spire located at the northeast corner. A tall, arched, rusticated porch leads to a round-headed door with a fanlight, flanked by open Roman Doric porches. The second stage of the tower has a panelled plinth, pilasters at the corners, and louvered belfry openings framed by architraves with consoled pediments on each face. The third stage includes a clock on each face set within a panel and a faceted spire atop a low octagonal stage. The ground floor has rectangular windows behind the flanking porches, while the remaining windows are segmental-headed, with square-headed windows above. The building features 12 and 16-pane sash windows, an eaves band, a cornice, and a blocking course, all topped by a piended and platform slate roof.

At the rear of the church is a low session house that connects to a single-storey, five-bay buttressed Gothic hall added in 1901, designed by architect John MacLelland of Kilbirnie. This hall is constructed of bullfaced snecked ashlar with polished dressings, featuring a porch with a pointed-headed door on the northwest gable and pointed-arched windows on the northeast wall. The hall has moulded skews with gableted skewputts and cross-finialed gables, along with a slate roof.

Inside the church, there is a panelled gallery supported by wooden Roman Doric columns. An organ by Foster & Andrews was installed in 1885, with pipes located behind the pulpit. The pulpit is flanked by stained glass windows at both ground and gallery levels. The ground-level windows depict themes of the Resurrection (circa 1928) and the Good Samaritan (circa 1913), while the gallery windows illustrate The Sower (circa 1883) and The Reaper (circa 1888). A southeast gable window from the hall, acquired in 1947 from the demolished former West church, features a Good Shepherd theme.

The church bell, cast by John Wilson & Co. in Glasgow in 1810, was recast in 1849 and again in 1903.
