## Project Overview
"Breathe_In," located in Cracow, Poland, addresses significant urban challenges related to air quality and community health. Situated in a city facing notable air pollution issues, the design intent focuses on merging natural elements with functional architecture to promote environmental awareness and enhance community interaction.

### Site Strategy and Community Engagement
The site plan includes several interactive zones designed to foster community engagement and well-being. An indoor patio provides a tranquil environment that allows for nature exposure, while flexible activity areas cater to diverse community activities, encouraging social interaction. Key features include a koi garden and an oxygen-enriched pond, which contribute positively to the local ecosystem while enhancing aesthetic appeal. Leisure decks, characterized by organic shapes and constructed with wooden platforms, offer spaces for rest and contemplation in a landscaped setting filled with native flora.

### Sustainable Materiality
The project emphasizes responsible material use and ecological integration. Cross-laminated timber (CLT) forms the structural basis, optimizing cost-efficiency and minimizing excavation impacts, while promoting climate resilience. The intelligent façade utilizes double-glazed glass with an interstitial layer of vegetation, facilitating natural ventilation and air purification. Green walls and a selection of indoor plants, including *Chrysalidocarpus lutecens* and *Hedera helix*, serve to enhance indoor air quality. Additionally, decorative grasses and native plant species are incorporated into the landscaping, supporting local biodiversity and creating inviting outdoor environments.

### Distinct Architectural Features
Among its notable characteristics, the project includes an oxygenator installation that emphasizes the importance of public spaces in promoting health. The adaptive climate system, integrated within the façade, utilizes sensors to optimize energy consumption while maintaining the greenery within the building. The architectural form of "Breathe_In" harmonizes with traditional Polish architecture, yet embodies modern design principles, reinforcing its commitment to sustainability and community healing.
