In the early 19th century (around 1820) the Lands of Park, or Park Estate as it then became, passed from the Irvines to a Mr Moir of Aberdeen. Moir was a man of some substance in Aberdeen and undoubtedly had commendable flair and taste, and a considerable bank account. He employed the famous Scottish architect, Archibald Simpson, to build him a grand house on a new site at Park in the then very fashionable Palladian style. This is reflected in the soaring pillars of the front porch and the single storey centre which is in perfect proportion to the two wings at each side. Moir broke new ground in the design of Park as it is one of the very few late Georgian houses to be built in the north of Scotland and must have seemed quite a departure from other houses that were built in the more traditional style of Scottish architecture.

The public rooms, hall, dining room and drawing room are spacious and delightfully proportioned with high curved ceilings and extensive finishings to the doors, etc. Interestingly the arrival of the turnpike road started to improve communications in Scotland at that time and with Park being only 12 miles from Aberdeen it became accessible for day visits rather than having guests to stay. A team of horses could draw a coach 12 miles in the hour before resting and this allowed Park to be used for parties that included a day visit. This is why the house provides grand public rooms but bedrooms that are, in general, less grand than those of other houses where staying was essential should one wish to visit. The current billiard room was originally the coach house where visitors horses would be rested and fed and the coachmen similarly looked after prior to a return to Aberdeen after a day enjoying Park.

One of the most fascinating features of Park is that the house is virtually unspoilt and unchanged from its original design apart from two changes to the rear of the house (by Sir Robert Williams, a later owner) and the conservatory which was added more recently by the Foster family. The house retains its original doors and finishings including delightful curved doors to some of the rooms and the original brass is present in shut plates, door knobs, etc. Recently the original Caithness stone floors have been stripped, cleaned and resealed. There is also a delightfully proportioned main staircase leading to the upper floor. Another wonderful original feature are the Victorian pedestal baths and the original tiled bathrooms, which so reflect its late Georgian and early Victorian periods. The original Victorian radiators remain throughout, although the hot water and central heating system is supplied by four very modern boilers to give 21st century comfort to guests at Park.

On the death of the old Laird, Derick Foster, in 1996 the house was completely renovated by his son and daughter-in-law, John and Clarinda. Their plan was to recreate the grandeur and comfort that had been originally intended by the first owner, Moir, and to look after guests in the greatest comfort and excellence. Park is well known for its superb salmon fishing on the River Dee and shooting throughout the coverts of the Estate. A very professional team of staff look after guests both on the Estate and in the house and delicious food is provided along with a superb wine cellar that is always a talking point for guests at Park.
