Architecture and continuing use
The earliest villa survives inside a complex of rubble and ashlar wings with towers, turrets, crenellations and Gothic windows. Additions wrap around earlier walls, while two main stairs, plaster ceilings, fireplaces and heraldic glass record the ambition of the nineteenth-century interiors.
Its story
A late Georgian house was enlarged in 1858 and again in 1890, the latter phase associated with James Thomson. It later became a hospital and then fell vacant. Council policy requires restoration alongside new development, but current community planning still describes hotel and housing conversion as a proposal.
Why it is included
Category B listing recognises a major layered country house whose architecture, institutional adaptation and unresolved reuse illuminate change in the Lesmahagow landscape.
What to notice
- Earlier villa fabric enclosed by later Gothic wings.
- Towers and crenellated parapets shaping the long silhouette.
- Estate structures and policies that explain the house’s scale.
Reading the surroundings
The house and estate are not assumed open and may contain dangerous structures or active works. Do not enter, bypass fencing or rely on development publicity as permission.
