Old Castle Resort Hotel is a distinctive thermal resort property in the Termal district of Kocaeli, where a historic and atmospheric castle-inspired architectural identity meets the restorative tradition of Turkish thermal wellness. Kolsan delivered a furniture programme that draws inspiration from the property s historic character, using warm timber tones and traditional craftsmanship-inspired details across thermal pool surrounds, guest accommodation, restaurant and lobby areas. The furniture creates an atmosphere that feels timeless and genuinely rooted in the heritage of this unique thermal destination. This project reflects Kolsan s sensitivity and experience in delivering furniture for Turkey s thermal and heritage wellness hotel environments.
