Sussex-based architecture firm Blue Forest  designed Eco-Perch that allows you to commune with nature with its natural, organic geometry maximizes the relationship between the inside space and the outdoor setting, ensuring the structure sits harmoniously within the landscape.

Here's more description from its designers:

The building sleeps 4 people and is delivered, assembled and commissioned in approximately 5 days (subject to site preparation). The eco-PERCH design is flexible and can be adapted to suit your site where existing infrastructure is already in place. With options to assemble your building on the ground or in the treetops there are infinite possibilities for creating accommodation with a difference“.
