Seafield Tower was built for Mrs Bartlemore in 1820 and remodelled in 1858 in the Victorian Scottish Baronial style. It was subsequently owned by Mr W.G. Barron. Seafield was put up for sale in February 1879, at which time it was described as having a Gothic porch, vestibule and hall off of which were cloakrooms, five public reception rooms, nine bedrooms, a servants’ room and large attic room, bathroom and W.C.s, kitchen, scullery, butler’s pantry, store room, closets, servant’s hall, larders and a laundry room. It was fitted with gas and had hot and cold water throughout the house. It stood in thirteen acres of ground in which were large fruit, flower and vegetable gardens, vineries, peach houses and a conservatory along with houses for the gardener and coachman. Also included in the sale were stables, haylofts, harness rooms, coach house, byres and outbuildings including a poultry house and dog kennels.
The tower, built by Mr John Boyd, builder of Ardrossan, was added to the rear in 1881 after Seafield was bought by Mr Archibald Douglas Bryce-Douglas, managing director of Barrow Shipbuilding and Naval Construction & Armaments Company, who donated the weathervane in the shape of a ship to Barony Saint John’s Church, Ardrossan, which is called the Bryce-Douglas. Following his death in 1891 Seafield was sold to Joseph Russell, a shipbuilder from Port Glasgow, was buried in Ardrossan Cemetery on 6th June 1917.
Towards the end of the 19th century Seafield House was used as a Hydropathic Hotel. In 1942 it was requisitioned as the headquarters of No. 2 Special Boat Section Commando unit, the special forces unit of the Royal Navy. It was taken over by Glasgow Corporation from the early 1950s until 2000 and became known as the Seafield Residential School. In February 1952, six boys died in a fire in the Viking Dormitory.
In 2004 Quarriers Homes sub-let Seafield from North Ayrshire Council and later bought the property renaming it Quarriers Seafield School. In 2014 the school closed, and the house was eventually sold. In July 2016 planning permission was conditionally approved for a partial change of use from school to Maximum Potential’s CIC gym. On 24 October 2017 Seafield was severely damaged by fire and has remained in its damaged state ever since.
