BYKO's biggest construction products store is in Breiddin in Kópavogur. BYKO also has 4 other stores across the country.

BYKO's story began in 1962 when Gudmundur H. Jónsson and Hjalti Bjarnason opened the first BYKO store on Kársnesbraut in Kópavogur. From the start the partners strove to provide their customers, professionals as well as general house builders, with outstanding service. These values of the entrepreneurs laid the foundation for the build-up of the company, which is now the leader in construction product sales in Iceland.

BYKO's directors and employees lay heavy emphasis on strengthening operations and improving services to their customers. In recent years, BYKO has established a niche for itself overseas, including building up a dynamic lumber company in Latvia. There lumber and various lumber products are produced, ensuring BYKO's customers a more favourable lumber price than before.
