No 58 And Attached Walls

No. 58 is an early to mid-18th century town house with attached walls, situated in Coinagehall Street, Helston. The building is constructed of granite rubble with keyed flat arches, though the ground-floor arches are concealed behind 20th-century fascias. The roof is steep, covered in grouted scantle slate, with a hipped return on the right, all hidden behind a plain parapet. Several reset 17th-century crested clay ridge tiles are incorporated. Brick stacks are located on the left-hand side and between the front range and the rear wing on the right. The building follows an L-shaped double-depth plan, with a parlour wing extending to the rear right.

The original front elevation was symmetrical, featuring five windows, though it has been altered. Mid-19th century eight-pane hornless sashes are present, except for a late 20th-century bowed shop window which substitutes for two original windows on the ground floor to the left. A central doorway is pilastered and features stepped consoles, a hood, and panelled reveals. The doorway contains an 18th-century eight-panel door with fielded panels. The right-hand return front has five windows with similar sashes, with two blind bays on the left.

The interior retains many original features. These include fielded dado panelling to the right of the entrance hall, a panelled and part-fielded arch between the entrance and stair hall, and an open-well staircase with egg and tongue moulding, scrolled brackets, turned balusters, a ramped handrail wreathed over the newel and fluted newels. The stair hall has a moulded cornice on the ground floor, and the landing features dado panelling and a moulded cornice to the ceiling, revealing a central circular rib. A dogleg service staircase leads to the first floor, featuring a closed string and turned balusters. A front right-hand room has full-height panelling, a moulded cornice, a six-panel door with fielded panels, and a boarded-over fireplace. The rear parlour wing features full-height panelling, a moulded ribbed ceiling with incised shells, garlands, rosettes, and dentilled cornices, niches with shaped shelves, and a mid to late 19th-century marble chimneypiece. Upper chambers include dado panelling, an original chimneypiece in the front room, and a late 19th-century marble chimneypiece in the rear room. The basement has a granite-flagged floor and fireplaces with granite jambs and timber lintels. Visible pegged trusses and some original 18th-century two-panel and six-panel doors are also present.

A high rubble wall is attached to the rear right of the parlour wing. The building is considered a fine example of a town house, retaining much of its original character.
