Case Studies

Beldorney4Beldorney Castle is a 16th century, A listed, tower house located in Glass, Huntly, Aberdeenshire. This property is one of the few Z plan structures left in the North East of Scotland and was also one of the first built. It was built by the Ogilvey family, and was later owned by a list of families including the Gordons, Lyons, Buchan, and Grant families. Beldorney Castle consists of a main block with the principal axis running north-south. At the South East angle is a drum tower whilst attached to the North West angle is a smaller square tower containing the main stair.

Aberdeen Sash and Case carried out full replacement and upgrading works to over 50 windows and as this was such a large job, the works were broken down into different phases which can be seen below.  Works started back in late November and are currently still undergoing. Scaffolding was set up around the property and all joiners on site held a CSCS card (this confirms individuals working on the property have the necessary training and qualifications).

Some of the windows that were previously 1/1 style have been replaced and changed back to their original 6/6 style giving the property a more traditional look. The windows were primed and undercoated on the outside but no onsite painting was carried out. High quality brass ironmongery was fitted to the windows.
