Children’s Eco Park “Beli Brezi” in Nature Park “VItosha” is built in 2013 according to project #BG0042 “Rebirth and preservation of traditional building technics and skills used in Bulgaria”, accomplished by Department of Nature park Vitosha in partnership with Norwegian Crafts Development – in priority field #4: “Preservation of the European cultural heritage”. The project is financed by Island, Lichtenstein and Norway through financial mechanism of the European economic area and the government budget of Republic of Bulgaria.
The building combines the functions of information, education and exhibition center, providing enclosed exhibition areas with the ability to be prepared children and student discourses about the biodiversity in the area of the Nature Park, ethnographic specificity, etc.
Inherently the project is the first of this kind and it sets the goals listed below:
In the process of designing and building were studied and applied different old building technics: stone masonry, half-timber frame constructions, block construction of uncultivated timber logs, walls made of adobe, wattle-and-daub walls, cob walls, timber beam construction with clay filling, timber shingles roof, clay render, etc. Natural building materials were used: stone, wood, unroasted earth clay and straw. There was tested building construction of timber logs with small diameter, so called “Ritlovitsi”, which are got from sanitary cleansing of the forest.
Some of the general advantages of the unroasted clay as a building material are distinguished:
Old heating systems like masonry stove (Djamal) and air under floor heating (Hypocaust) are used.
Knowledge transfer and exchange of experience in the field of traditional building technics used in Bulgaria and Norway was performed in the process of research and design.
In combination with the Museum of the Bear, Museum of Dragonfly and Museum of Owls, which are situated near, and recently finished informational alley in the area “Iglikina Poliana”, the children’s eco park provides excellent opportunities for student’s green school and contributes for extension stay of the visitors of the park when the weather conditions prevent outdoor lessons, providing suitable conditions for activities in a cozy atmosphere.
