The clients had owned the lakeside plot for years but struggled to find a design that matched the quality of the setting. The brief was simple: a home that respects the lake, the trees and the Bavarian light.
The Classic 120 was configured with a single open-plan ground floor opening directly onto a cantilevered terrace over the water. The upper level contains three bedrooms, each with its own view corridor through the forest.
The ZeroEnergy package — geothermal heating combined with a 12kW solar array — means the family's energy bills are negligible, even through Bavarian winters.
The Tegernsee plot is a rare south-facing lakeside parcel — protected forest to the north, direct water frontage to the south. Bavarian planning rules required the home to remain below the existing treeline and respect the historic setback from the water.
The family brief: a year-round home for four with enough flexibility for extended stays. Energy independence was a firm requirement.
The Classic 120 was oriented to maximise south-lake exposure. The ground floor is a single open plan — kitchen, dining and living — opening via full-height sliding doors to a cantilevered terrace that steps directly to the private dock.
Each of the three upper-level bedrooms has its own view corridor framed through the forest canopy. The roof pitch follows the local vernacular but the material palette is entirely contemporary.
Douglas fir cladding was left untreated to silver naturally, blending with the surrounding pine and birch within a single season. The structural frame is Austrian spruce glulam with visible joints at the terrace connection.
The ZeroEnergy package combines a 120-metre geothermal loop with a 12 kW rooftop solar array. The battery system stores summer surplus for the shoulder seasons.
"The build was fast, the quality was exactly what was promised. We were in by October, in time for the first winter."
The family moved in by October 2022 — ahead of their first Bavarian winter. Energy monitoring over the first 12 months showed net-positive generation: the home exported 1,800 kWh to the grid.
The terrace-to-dock connection has become the defining feature — the clients describe the home as inseparable from the lake.
