Dales House, Peterhead

Dales House is a detached single-storey cottage orné with an attic, built around 1800. It stands in Dales Park, Peterhead, and is constructed in harled granite with smooth grey granite dressings, narrow corner margins and cavetto splays to the openings. A granite base course, cill course at ground floor level and a moulded eaves course run across the building. The three bays are arranged symmetrically, and the front elevation features four-centred arches with Gothick tracery.

The front, south-facing elevation has a distinctive bowed and ashlar porch at its centre, finished with a moulded cornice. The porch contains an arched entrance with a fanlight above inscribed with the name "Dales House", though the entrance door is a later replacement. Curved window panes flank the entrance. Above it sits an ogee-gabled dormer breaking the eaves line, with moulded and painted timber surrounds and a finial.

The east and west elevations each carry a flat-roofed canted bay window with granite mullions and cills. The west elevation has three additional attic box dormers. Glazing patterns vary across the house: the canted bay windows contain 12-pane glazing while the attic dormers have 20-pane glazing. Most frames are timber sash and case, with some later casement replacements at the rear and sides.

The slated roof curves down at the front corners and pitches at the rear. Slated box dormers are positioned on both roof pitches—three on the west and two on the east. Distinctive triple diamond-shaped end chimneysstacks with tall clay pots mark the front elevation.

The interior, inspected in 2019, has been substantially modernised but retains 19th-century period styling including moulded cornicing, decorative panelling, moulded architraves and panelled timber doors.

The Dales estate does not appear on pre-19th-century maps. The building is first recorded on the 1st Edition Ordnance Survey map (surveyed 1868, published 1869) as "Dales Cottage". According to the Buildings of Scotland, the canted bay windows and porch were added later, though the property had been built by 1850 when it served as the country residence of James Arbuthnot of Invernettie and Dales (1821–1873), evidenced by the birth of his son there in that year. The Ordnance Survey Name Book (1865–1871) describes it as a large and substantial cottage with offices, garden and adjoining farm, set within a small-scale country estate including a gatelodge, private drive and walled garden.

The Arbuthnot family retained ownership until around 1900, when it was sold to Henry Mitchell, procurator-fiscal for Peterhead. The building became known as Dales House sometime between 1924 and 1954. In 1954 the Dales estate was advertised for sale, including the house, policy enclosures, home farm, walled garden and lodge cottage. The walled garden then operated as a commercial market garden with glasshouses, cold frames, heating system and potting sheds.

Large portions of the estate farmland were sold to Aberdeenshire Council in 1974. Dales Industrial Estate was subsequently developed in the southwestern part of the former policies, and Dales Park was created from remaining green space to surround the house and walled garden. A U-plan building to the west, likely former estate offices or stables, was demolished in the mid-20th century and replaced by a house after 1997.

Dales House underwent renovation around 2007 following a period of vacancy and possible fire damage. Works included addition of boundary walls, a detached double garage at the rear, and internal alterations and extensions. The house and walled garden are now in separate ownership.

The following are excluded from this listing in accordance with Section 1(4A) of the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997: the single-storey rear extension, the glazed porch addition on the west elevation, detached garage, boundary walls and the separate walled garden to the southeast.
