There’s something fantastically Finnish about this family house on the Jollas peninsula, located southeast of Helsinki. Could it be the homey modernism balancing clean geometric lines with warm timber cladding? The windows perfectly positioned to ensure privacy from the neighbors while taking full advantage of winter sunlight and ocean views? Designed by Helsinki-based Oratraum Architects, the home was built for an active family of five. …Both the ceiling and floors are made of naturally hued cross-laminated timber. Upstairs features a suspended-netting lounge, master bedroom, and three children’s rooms—which are outfitted with a trapeze and climbing wall.
