What additions projects look like in Kennett Square
The Kennett Square homes we work in are mostly 1880s–1930s borough Victorians, plus newer farmhouse-style construction, typically restored Victorians, modern farmhouse, and stone twins. We've completed projects across Kennett Square borough and the Longwood Gardens corridor.
Kennett Square's Victorian inventory means a lot of our work involves restoring or thoughtfully modernizing period detail, wide-plank hardwoods, original millwork, and trim that matches the era.
