Lundsbergs boarding school has eight houses, six of which are being used today. Each house has its own facilities, customs and traditions, and each compete against each other in a variety of activities for trophies to increase the house's reputation. There are around 220 students currently enrolled at the school, with the vast majority being boarders. The houses are:
Berga Opened its doors 1924. In 1942, Berga became the Principles House and students were relocated to Skogshult.
Björke Was completed 1899 and is the school's third oldest student house. The house was originally boys-only, however Skogshult was renovated during 2014, making Björke into a mixed house. Now Björke is a boys-only house again. Its colours are red and white.
Forest Hill Finished 1898 and was the second house built on the school campus. Mary Cooper, the founder William Olsson's sister, decided to name the building Forest Hill at its opening ceremony. Its house colours are black and yellow.
Lilla Hill Forest Hill recently (2019) opened a second house, Called Lilla Hill (Small Hill).
Gransäter Was completed 1902. It is often called "Royal Gransäter" because of its former students being Prince Gustaf Adolf (from 1918 to 1924) and Prince
