Tags: Sustainable architecture, Contextual architecture, Interaction with the surrounding environment, Birth, Growth, Tree.
Production Technology: The design should interact with the surrounding environment so that the structure does not initially cause problems for the user and gives a broad view of the plan. In addition to the variety of different entrances and accesses, it is like passing through stages, so as much as possible, the tree located in the center of the site is preserved, and a building with a creative form and response is designed to attract the audience as a unique work according to the needs of the client.
Design Challenge: The design represents dynamism and social interaction, inspired by the growth of a seed in a tree, symbolizing upward movement and spirituality and reflecting the Sufi dance. Sunlight shines through the void into the tree and manages the intense sunlight through a concrete filter on the facade. The entrance steps inspire growth. The recessed and protruding forms create an attractive and harmonious architectural environment. They invite the audience to spend time in or look at the complex.
Research: When designing a building with two main uses, one for general use as a coffee shop and bookstore and the other for specialized use as a digital shopping complex in a busy location, the designer considers a scenario for each part. Given the project's constraints, he uses this challenge as an opportunity and draws inspiration from the growth of that tree to, like the branches of a tree, plan the layout in terms of the type of access to each use and the use of each material and element.
Inspiration: The complex supports young people by eliminating office startup costs and the needs of startups. Inspired by a bud to an old tree that symbolizes growth, the building is divided into two parts: an office and a cafe below street level. Design features: a central void, a cafe roof shaped like a dance of Sama, a concrete facade that controls sunlight, and stairs inspired by musical notes that symbolize progress. Traditional Iranian tiles and handmade bricks increase attractiveness and interaction.
Project Duration: The design of this project began in January 2025 and finished in March 2025, in Istanbul, Turkiye.
Operation Flow: Buildings should be like living organisms interacting with their surroundings, especially those with public uses, in a way that invites their audience to spend some time there. This project decided to build a building that interacts with the environment, considering the client's wishes and location in a busy area. Also, the presence of a tree on the project site inspired this research, which can be preserved to design a landmark building.
