Hotel Stara planina, a member of Falkensteiner group was open for public in 2012. It is situated on Stara planina mountain, at the altitude of 1.466m. This is a perfect place for a family vacation, due to skiing tracks, surrounding intact nature, as well as diversity of leisure facilities. The hotel has many amenities, such as: restaurant, lobby bar, pizza restaurant, indoor pool, playground for children, skating yard, wellness and spa center. Considering the diversity of the activities offered, the illumination had a lot of different technical requirements to fulfill, with the task to follow the forms of simple yet warm interior. Main communication spaces of the hotel are characterized by joyful alignment of linear luminaires, whose composition is continued on the wall of the main atrium. In the entering hall and reception, the illumination is built in the elements of the interior (wooden panels, desks, suspended ceilings) as lines of indirect LED light. Dining and entertaining rooms have a warm relaxing character with a touch of extravaganza. The pool, wellness and gym are spaces with high technological demands, due to maintenance and humidity issues. The pool is illuminated using LED spot lights in high IP degree, combined with LED indirect light lines. The gym has minimalistic interior illuminated by long light lines of a uniform light diffusion. Rooms maintain a quiet and warm ambience, flexible in forming diverse functional zones. Outdoor illumination is mainly functional, while the facade is decorated with discrete narrow lines of warm white light.
