Ecologically sustainable house is a Djuric Tardio exciting project of architect designed and located in a dense suburb of Paris, France. The residence was entirely with wood panels on a base (because of the irregularity of the terrain). Then the house was completely prefabricated in a workshop at a location to be delivered fully assembled in less than two weeks. The most fascinating element of the crib is the pergola, or the unfinished roof, with a feature architects explained as follows: firstly, it must be the archetype of the context of the project in its environment without disrupting the rhythm Urban, on the other hand, there is not enough space for a closed roof, with a tote or attic space be wasted. So we introduced residents in them, and have left open by turning it into a vegetable, intimate and sunny terrace. The presentation of the project is very flexible, with very few changes, the room can be transformed through the modular design approach.
