Flowerfield House, 38 Crevolea Road, Blackhill, Coleraine, Co. Londonderry, BT51 4ES

Flowerfield House is a detached symmetrical three-bay two-storey rendered house built around 1816, with a two-storey return and extensively renovated around 1990. The building is T-shaped on plan, facing south, and forms part of a farm complex with a rectangular cobbled yard to the rear lined with rubblestone outbuildings.

The house was originally built as the home of a linen merchant and later served as a manse for Agahdowey Presbyterian Church from the 1870s onwards. It retains much of its early nineteenth-century character, with good proportions and symmetry throughout. The interior preserves much of its original joinery details.

The pitched natural slate roof features roll moulded terracotta ridge tiles and rendered chimneystacks to both ends, with replacement rainwater goods to boxed timber fascia. The walling is rendered in flint dash. Square-headed window openings have smooth render surrounds, concrete sills, and replacement timber sash windows with aluminium covering. The three-bay symmetrical front elevation is abutted by a central entrance porch with canted bay windows to either side, added in the 1990s. The porch has hipped natural slate roofs with rolled lead ridges and a lead-lined roof. The entrance features an elliptical-headed door opening, reproduction tripartite timber glazed entrance screen, and fanlight.

The west gable has a central window opening at ground, first, and attic levels, with the attic window being an original timber casement. The rear elevation is abutted at the centre by a two-storey return with a single-storey lean-to addition to the northeast re-entrant angle, irregular fenestration, and a blank return gable. The east gable is fenestrated like the west gable and has a square-headed door opening to the right with a replacement glazed timber door.

The setting is on a mature wooded site to the north of Crevolea Road, accessed via a winding bitumac drive that divides to provide separate access to the rear yard. The drive opens onto the road via a pair of curved rough-cast rendered walls and piers. The rectangular rear yard is laid out in cobbles and is surrounded by outbuildings: a two-storey lime-washed and rendered range to the west with a natural slate roof, vertically-sheeted timber doors, and external stone steps; further single-storey and derelict rubblestone outbuildings line the remainder of the yard to the north and east. The property retains wrought iron gates, pillars, and an original gate screen.

Historical records show the house was recorded in the first edition Ordnance Survey map of 1831–32, with further outbuildings added by the second edition of 1849–52, when the house was captioned "Flower Field". A rear extension was added by the third edition of 1904. Griffith's Valuation of 1856–64 lists Samuel L Cox MD as occupier, leasing over 13 acres from William Hemphill. The Hemphill family were known locally as owners of bleach greens in the area. Subsequent residents included William Hemphill, Robert Lees, and Thomas Barklie. From the 1870s the house became a Presbyterian manse, with Rev James Huston resident from 1876, followed by Rev Gilbert Kennedy and Rev Samuel W Morrison, who lived there at the time of the 1911 census. The dwelling continues in domestic use.
