Cottys Brow, Numbers 1, 3 and 4

This is a row of three houses, originally four, located on Cotty's Brow in Southport. Dated 1737, as inscribed on a spine beam inside number 3, the houses have been altered over time. The exterior is rendered and painted white, with the exception of number 4. The roofs are slate, with red ridge tiles and brick chimneys. The houses have a single-depth, linear plan spanning five bays, although number 1 now occupies three bays, incorporating the former number 2.

The houses are single-storied with a seven-window front, arranged in a 2:2:3 pattern. Number 1, the right-hand section, includes an added, off-set gabled porch, along with two three-light sliding sash windows on the left and one on the right. Number 3 has an altered, flat-roofed porch at the central junction and two enlarged and altered windows to the left. Number 4, to the left of number 3, has a shallow gabled porch at the left end and two segmental-headed two-light casement windows. Chimneys are gabled at the left end of number 4 and ridge chimneys are positioned at the junction of numbers 1 and 3, and within number 1.

The rear of number 1 features two three-light sliding sash windows and a 20th-century flat-roofed extension. Number 3 has a 20th-century outshut, while number 4 has an outshut containing two three-light sliding sash windows with early 20th-century stained glass.

Inside number 3, a spine beam is inscribed with the date 1737, and it includes stop-chamfered spine beams with run-out stops. These houses are a recognizable example of a historic type of dwelling once common in the area and are particularly significant due to their recorded date. They form a group with First Cottage and Second Cottage, at Croston's Brow.
