Apelsinvillan, Protected summer house in Lidingö Municipality, Sweden

Apelsinvillan is a late 19th-century summer house on the wooded shore of Kottlasjön lake in the Skärsätra area. The light-colored wooden building has a two-story veranda with carved details, a metal sheet roof, and two small sheds beside it.

Built in 1890 by carpenter Per Johan Asker, the house was one of many summer homes that appeared near Kottlasjön at that time. In 1897 it was bought by former Stockholm shoemaker Johan Fredrik Källgren, and it remained in his family until around 1970.

The name comes from the orange wooden balls decorating the upper part of the veranda, which many people think look like oranges rather than lanterns. Today the house still serves as a year-round family home, keeping the relaxed feel of an old lakeside summer retreat.

The house is a private home, so visitors can only view it from the outside along Vinkelvägen. Walking or cycling to the site gives a better sense of the lake setting, and the ground can be wet near the water after rain.

Part of the timber frame and several interior doors were reused from buildings dating back to the 1700s. During a careful restoration in the 1980s, the exterior was repainted to match its very first color scheme.
