Architectural Features
Williamston House is a two-storey Grecian-style house with columned porch. It is listed category B and was originally built in 1825 by the Aberdeen architect Alexander Fraser. The wings were added in 1850s. Williamston Home Farm is listed category B and surrounds an early 19th century courtyard with a threshing mill turned by horses, kennels with a dovecot above, a separate guest stables and the usual byre and farm buildings; most of the farm buildings are in some disrepair.
St. Michael's Well is a pre-Christian sacred well now used as a garden ornament. The Statue of St. Michael is by Barbara Austin Taylor, completed by Richard Robertson in 1952. There is also a Statue of St. Francis, and a Sundial mounted on a column decorated with four cherub heads.
Parkland
The parkland was laid out during the mid-19th century; it runs down to the river and rises up the far side to the A96. The lake was made by Mr Haughton c.1930. The remnants of the clumps of trees, mainly beech, were planted c.1830 and frame the magnificent views to the south. The entrance drive which sweeps up the slope along the side of the woodland, is bordered by ornamental conifers and Rhododendrons planted in the 1870s.
Woodland
Charles Fraser planted the first woodland of over 250 acres (101ha) on the Hill of Skares from c.1804. From 1831, his son planted the shelterbelt strips and the woodland protecting the house with beech, oak and some sycamore. Edward Fraser planted some Douglas fir in the plantations and extended the woodland above Kirkton. The disastrous gale in January 1953 blew down over '90%' of the mature timber in the shelterbelts and woodland near the house. Most of the plantations have since been replanted with conifers.
The Gardens
The lawn around the house was extended c.1914 when the ha-ha was built. Edward Fraser began planting the Rhododendrons c.1872 and a bill from Benjamin Reid, dated 1873, has an entry for over 1,400 Rhododendrons as well as many other trees and shrubs listed on his invoice. He also opened up the woodland to make the sheltered garden and cut a strip between the house and the garden which he planted with exotic conifers. Some of his evergreen shrubs, the large Douglas firs and Wellingtonias remain. Between 1900-1910 the garden was so neglected that when the Haughtons returned they cleared the tangle of Rhododendrons and levelled the ground creating the framework of the present garden, including the vista through the woodlands to the Hill of Foudland.
As Theodore Haughton was an artist and had trained in France, he was interested in the design of the garden and texture of the plants. Except in specific areas, colour was avoided and, instead, the rich foliage of the plants was used to create strong contrasts between bright sunlight and dark shade. The shape and form were more important than the plant species so there are no particularly unusual or rare plants in the garden.
The 'Broad Walk' leads from the house to the garden, and on either side, behind a line of Irish yew, shrubs and small trees were planted following the gale. Narrow, intimate grass paths weave through and round them producing continual changes and contrasts. The garden is entered between two old stone pillars, once the entrance to a field, and the path leads to the 'magic' circle and to the statue of St. Francis in the Fountain Garden beyond. The circle is crossed by the main allee surrounded by a hedge of clipped yew and box with openings for four other vistas across the garden. The broad herbaceous borders on either side of the allee were filled, amongst other plants, with delphiniums, phlox, lilies and lupins. The allee leads to the Statue of St. Michael standing in a simple semi-circular lawn at the end of the long vista.
Behind the hedges are a series of small gardens including the Rose Garden which is bright and colourful, the Rockery, and the Water Garden around the ancient well. Here Primulas, lilies and other moisture-loving plants grow surrounded by a beech and hornbeam hedge. Some fruit and vegetables are still grown in their own compartment. The garden was highly individual and its structure shows a strong French influence.
