The World Commission on Environment and Development defines sustainability as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainability is a buzzword that has already infiltrated many industries. With construction being a significant contributor to global energy consumption, it is no surprise that sustainable architecture has become a leading consideration in build buildings and cities. Sustainable architecture is also referred to as green architecture or environmental architecture. It challenges architects to produce smart designs to ensure that structures generate minimal harmful effects to the ecosystem and the communities. Accordingly, our architectural firm decided to design and implement the Cabana II project in Ajoodanieh, Tehran, Iran. The site was a relatively steep, tree-lined plot of land where office land-use were to be located and executed. In the first step, we examined the area, obtained the minimum spaces for design, and identified the trees' position. Then, without removing the slope or damaging the specific greenery of the site, 32 cabanas were located and built. We connected both cabana numbers by a bridge and turned them into a micro-scale office land-use. We aimed to separate public space (office part) from the private area (the management) without damaging the vegetation. In addition, these two parts lead to a shared space, and they have an enclosed bridge with trees, so there is a pause and interaction for the users in this complex. Furthermore, we used sharp and sloping roofs to observe the skyline and position our architecture method in the existing nature concept. We also note that the materials used in the Cabana II project are indigenous and light, and the cabanas themselves are portable. The Cabana II project puts users in a shared space to get common feelings from nature and achieve a lot in common and friendly companionship.
