History

The house and associated yard buildings formed the centre of the Fitzwilliam family estate which once extended to 90,000 acres

The current main block of Coollattin House was rebuilt after the 1798 Rebellion to the design of architect John Carr of York. It comprises a pedimented south facing entrance front with centrally positioned bow windows to the east and west sides . Its internal plan is designed around a central stone staircase with dome at roof level.

During the 19th Century the original house was extended with wings to the east and west. The east wing  provided a new pillared entrance porch, leading to a vaulted entrance hall and Italianate staircase linking with the original house. The west wing was designed to provide service accommodation including a high ceilinged kitchen.

To the west of the main house two linked  yard buildings were designed to contain additional guest and staff accommodation, stables, coach houses and a laundry and drying room.

The particular interest of Coollattin lies in its evocation of the life and working of an Irish country house in the 19th. Century. Features include the library with built in mahogany bookcases, a functioning dumb waiter lift, original kitchen fixtures including cast iron cooking range, a vaulted passageway to link the basement with the laundry, and stone floored stables with oak doors to the stalls.

20 acres of the original grounds remain with the house. These contain a collection of specimen trees and  a variety of hybrid Rhododendrons with peak flowering in the April May Period .

 Since  2021 the house and grounds have been in the ownership of Coollattin House Partnership which is advancing an ongoing restoration programme  to reflect  and enhance their historic character.
