As part of the restoration of Grant Lodge, we are carrying out a series of carefully controlled investigation and test areas to better understand the condition of the building before major refurbishment works begin.

Grant Lodge is a Category B listed building with more than 250 years of history. Specialist surveys and material analysis have shown that much of the existing external render is a later cement-based coating, applied during the 20th century over earlier traditional finishes. While cement render was commonly used at the time, we now understand that it can trap moisture within historic masonry. Over time, this can contribute to the deterioration of the stone and mortar hidden beneath the surface.

Specialist conservation contractors and consultants are:
• Carefully removing small sample areas of the existing cement render
• Assessing the condition of the historic stonework and mortar beneath
• Helping determine the extent of repairs needed as part of the wider restoration project
• Creating trial panels of traditional lime render and limewash
• Testing different approaches to the treatment of window surrounds and corner stones to help inform the final restoration design.

These investigations build upon extensive surveys, laboratory testing and historic building research already completed for the project.
