How can thoughtful design tackle the challenge of rising land values in dense urban environments? The Aruma Split Garden by Indonesia-based architecture practice RAD+ar offers an innovative solution, showcasing how split-level design can create distinct zones within a multi-tenant compound while seamlessly integrating nature into the built environment. The project is a prototype that optimises circulation and demonstrates the practice’s commitment to sustainability and innovation.

In contemporary architecture, split-level design has gained popularity for its ability to maximise space efficiency and create visually interesting hospitality interiors. This approach divides a building into multiple levels, often with half-stairs, which helps to separate living areas without completely isolating them. It allows architects to better use challenging sites, such as sloping terrains and provides a way to integrate different functional zones within a single structure. This method makes the space well-organised and also integrates nature within a relatively compact footprint. "We wanted to ensure a seamless transition between the different levels and spaces. By creating a looping circulation from the front garden diagonally through the building, we allowed for a fluid flow between three tenants: restaurants on the ground floor, a bar in the mezzanine space and a beer garden extending to the rooftop,” the Indonesian studio told STIR.

Local climate and environmental conditions played a significant role in shaping the design of the Split Garden. One of the key challenges was preserving the existing greenery in the rear garden while efficiently utilising multi-level commercial spaces. The building's north-south orientation was carefully chosen to improve spatial experience and boost wind circulation. This alignment creates a wind tunnel effect, enhancing natural ventilation and connecting two large trees at either end of the site. This orientation also helped preserve the existing greenery, allowing the outdoor spaces to blend seamlessly with the indoor areas.

One of the unique aspects of the design is the concept of "appreciating gardens between spaces." This involves strategically placing gardens to ensure smooth transitions between different areas and materials within the development. This enhances the visual appeal, providing a calming and refreshing atmosphere. The integration of structural elements into spatial planning brings a seamless transition between different levels and spaces.

The incorporation of diverse plant species in the Split Garden’s facade design serves more than an aesthetic purpose. These plants are selected for their ability to improve air quality and provide natural cooling, enhancing the building’s environmental performance. This choice reflects a broader trend towards incorporating biophilic design principles, which aim to create healthier living environments by connecting people with nature.

As urbanisation accelerates, the need for innovative architectural solutions becomes more pressing. The Jakarta-based project addresses this challenge by demonstrating how high-density living can coexist with nature. The project underscores the importance of designing spaces that not only serve practical purposes but also enhance the quality of life for their occupants. By integrating natural elements and enhancing movement flow, it sets a new standard for urban architecture in living spaces.

RAD+ar's approach to design diversity is grounded in a holistic understanding of urban design and environmental dynamics. By embracing a multidisciplinary approach, they not only enhance the built environment but also foster connections between people and places. Their portfolio reflects a strategic blend of functionality and creativity, where each project catalyzes sustainable living and community engagement.

Environmental sustainability guided every aspect of the design process. From efficient material use to enhancing energy efficiency through ingenious structural design and construction techniques, the architects focused on minimising environmental impact in restaurant design. Their selection of sustainable materials further underscores their commitment to eco-conscious building practices. "By targeting optimal integration, we aimed to seamlessly blend different elements and components within the building. This approach creates a harmonious relationship between functionality, aesthetics, context, sustainability and user experience,” explained the architects.

Beyond its architectural merits, the project serves as a community hub, fostering social interaction amongst its tenants and visitors. The carefully designed spaces, including the rooftop beer garden and mezzanine bar design, encourage social activities and create a sense of belonging in hospitality architecture. This focus on community building enhances the overall experience, making the space not just to live and work, but a vibrant part of the social fabric.

Moreover, RAD+ar's design philosophy extends to promoting mental well-being. The integration of natural elements and open spaces within the spatial design projectis intended to reduce stress and improve the mental health of its occupants. By creating environments that prioritise both physical and psychological health, they demonstrate a holistic approach to restaurant architecture that goes beyond mere aesthetics and functionality.

Reflecting on the Aruma Split Garden, RAD+ar emphasises the importance of decentralising sustainability in commercial developments. By integrating green roofs, the architects hope to inspire designers in developing countries like Indonesia to prioritise sustainable design in urban landscapes. This project promotes a commitment to environmentally sound practices and fostering responsible community engagement. It advocates for a future where urban environments coexist harmoniously with nature, enriching the lives of city dwellers and setting a new standard for urban development worldwide.
