Located high on Airngath Hill in West Lothian, with fine views over Linlithgow a mile (1.6 km) to the south, Grange is the Baronial-style home of the Cadell family, who made their money as iron-founders. Geographer and geologist Henry Moubray Cadell (1860 - 1934) commissioned the Edinburgh-based architects J. N. Scott and A. Lorne Campbell, to design and build his home between 1904 and 1909, with the date-stone recording 1907. The house lies close to the modern boundary with Falkirk Council Area, on an estate initially leased by industrialist William Cadell (1708-77), principally for its reserves of iron ore, and then purchased by the family in 1778. The current house replaced the earlier Grange House or Old Grange, a T-plan tower-house which was built in 1564 for Sir John Hamilton and demolished in 1906.
The Grange is a splendid Edwardian creation, part-harled and part-sandstone ashlar, with Renaissance details. It comprises two storeys, built around a quadrangle, accessed by an archway to the north. It is dominated by a four-storey tower to the southwest, which contains the geological museum of H.M. Cadell on its upper floor. There is also a conservatory. Inside, the entrance hall is oak-panelled. There is a bright white-panelled drawing room with art nouveau details, an oak-timbered library to the north, a dining room in the southeast corner, which is decorated with family portraits and features a beamed ceiling. Adjacent is the former billiard room that also has a beamed ceiling. Although changes were made to the design as work progressed, which affected both the location and form of the principal rooms as well as the detailing, virtually nothing has been changed since the house was completed and the original fixtures and fittings remain throughout.
The house was A-listed in 1971 and is made available for weddings and exclusive corporate events. William A. Cadell began his architectural practice in the family home in 1968. This became the Pollock Hammond Partnership on Cadell's retirement in 1994 but it still operates from Grange West.
In the grounds there is a sunken terrace garden with a loggia (1905, by the same architects as the house), while nearby is a walled garden which is C-listed.
