This Forest House Will Completely Change Your Thinking Of Living In The Forest

Haus Koeris is a private residence that is situated near a lake in close proximity to Berlin, Brandenburg, Germany among tall pine trees and created by Zeller & is built-in the year 2020. Its structure is made entirely from wood as you can see. the building is elevated from the ground to minimize the impact on the land and to avoid contact with the seasonally damp soil. The irregular shape of the house stems from the position of existing trees. Five boxes are arranged in a staggered layout with the individual rooms overlapping each other allowing for connections between them. The shifts in the floor plan create small patios and green niches along the building‘s perimeter. Some of these alcoves are sheltered from the wind or hidden from views, others capture the sun and thus create pleasant microclimates. The recesses give the residents various opportunities to use the exterior as inhabitable open-air spaces in dialogue with the internal rooms, proposing a new relationship with nature where indoors and outdoors blend into each other.

The inside of the single-story house is organized as a cluster of spaces of various clear heights – 2.4 m, 2.7 m, and 3.1 m – offering a variety of private areas and an open shared space, adding up to a total of 130 m2. The generously proportioned central space is the heart of the house where the residents come together, cook and eat around a large table, or rest in front of the fireplace. Three flexible rooms connect to the central space distributed on both sides. Depending on what is required at the time, they can be used as a bedroom, studio, workshop, or guest room. Their location at opposite ends of the house allows for good acoustic separation, therefore even at nighttime sleeping and working can occur simultaneously. All interior spaces feature pale wooden walls, floors, and ceilings. Large windows in an irregular distribution interrupt the calm interior with scenic views of the woods, that at times may appear as landscape paintings. Connecting the interior with the surrounding scenery, some windows are specifically positioned to create framed views of the nearby trees. Four entrances connect the house with the garden. The main entrance is hidden within the central patio opening up directly into the living space. A secondary door connects the bathroom with the garden leading up to an outdoor shower that is tucked away in a niche covered by vegetation.

In order to maintain the existing pine trees, the house had to not only be designed around the tree trunks but also had to avoid any harm to the tree’s horizontal root system. The construction was therefore raised from the ground minimizing the footprint on the land. A light wood construction rests on individual concrete foundations that are laid out on a grid allowing for the roots to grow around them. Thanks to the chosen wood construction it was possible to deliver the house on a low budget. The building is based on environmentally sustainable construction principles including the use of renewable resources such as solid wood floors and ceilings, a modular wall system of wooden building blocks, and wood fiber-based insulation. The façade is made of vertical slats of regional spruce wood that thoroughly wrap around the house as well as the three entrance doors. Large fixed glazing in combination with smaller operable windows for natural ventilation allows for light-flooded interior spaces.

The internal climate of the house is more comfortable than a regular construction of cementitious materials due to wood´s natural capability of temperature and humidity regulation. During the cold winter months, the exposed wood surfaces are enjoyable to the touch and contribute to a warm interior by reflecting the heat. A wood-fired stove provides comfortable radiant heat based on a renewable energy source, while a biogas boiler provides general heating to all rooms. As an environmentally friendly solution, a small sewage plant with biological treatments is installed on the lot, cleaning all wastewaters of the house before releasing the clean water back into nature. In a second phase, vegetation will be planted on the roof, further increasing the insulation of the building and contributing to the land’s eco-system.
