Project Description
The theme for this project is to to design a small retreat for a writer placed in the forest. Due to the location, a big part of the project is to work with the implementation of passive and active strategies regarding living off-grid. 
 
In the design of the retreat I was inspired by a walk in the forest. From when you walk into the forest, the trees closes over you and make it dark and dense. When arriving at the lake, Pebermosen, the forest opens up and the sky and light are experienced once again. In the same way, the house is dark and small in the entrance, but the further into the building you walk, the lighter and more open it becomes, until arriving in the living room where big windows reveal the light and a view to the lake. The shape of the roof defines, furthermore, the concept, by being a hyperboloid paraboloid.

Passive strategies & Off-grid solutions

To achieve the idea about living off-grid with no connection to the grid’s water, electricity or sewage system, I found different options to implement in the cabin. The diagram below shows, furthermore, different multifunctional furniture, which are useful in tiny houses like this one. 

Construction

The materials for the cabin are chosen according to sustainable reasons. 
 
Kebony wood is used for the facade covering and for the structure. It is a softwood treated with a bio-based liquid which provide hardwood characteristics and a deep brown color. Using UV-protection oils, the color can be maintained and avoid patinating to a silver grey color. 
 
As insulation material in the walls and roof, seaweed has been chosen. The material is naturally flameretardent and is CO2-neural. It can be reused to new insulation batts, while still maintaining the same high insulation value as other insulation materials. 

In all our projects we work with the construction and consider how the elements are connected at exposed places. Therefore, detail drawings are made to show how specific details will be solved. Below is a detail drawing of the wall and a window, and shows how to avoid thermal bridges.
