Foster + Partners Break Ground on Two Iconic Towers in Manila with Innovative Exoskeleton Design
Manila, Philippines – British architecture firm Foster + Partners has begun the construction of two stepped-back towers for the BDO Unibank Inc campus in the Philippines, designed with exoskeletons to enhance structural stability and provide effective solar shading. This development will reshape five urban plots in Manila, featuring a futuristic design that combines modern engineering with traditional design cues.
Architectural Design and Features
- Stepped-Back Towers:
The two towers will feature stepped-back facades, a design inspired by vernacular architecture, creating triple-storey amenity spaces and outdoor terraces at each interval. The layout aims to maximize natural light while integrating sustainable features. - Exoskeleton for Solar Shading and Stability:
Each tower will be supported by an exoskeleton that accommodates woven metal-mesh infill screens, which draw inspiration from traditional weaving patterns. These screens will provide solar shading, particularly to areas exposed to intense sunlight. Additionally, the exoskeletons will ensure the buildings are seismic-resistant, vital for the region. - Structural Efficiency:
The use of external exoskeletons allows for column-free interiors, increasing space flexibility and functionality. Foster + Partners also highlighted that the structural design reduces concrete usage by more than 65,000 tonnes, contributing to a more sustainable building process.
Environmental and Sustainable Features
- Recycled Water and Urban Farming:
The campus will feature an urban farm on the rooftop, where food will be grown for the staff canteen. In addition, over 70% of the campus’ potable water will be recycled and reused, showcasing the studio’s commitment to sustainability. - Green Mark Super Low Energy Certification:
Foster + Partners aims to achieve the Green Mark Super Low Energy certification, a prestigious rating for buildings that achieve at least 60% energy savings compared to 2005 building codes. If successful, the BDO Unibank campus will become the first building in the Philippines to achieve this rating.
The Vision Behind the Project
- A New Workplace Model:
According to Luke Fox, head of the studio, the BDO Unibank campus offers a new model for flexible, climatically responsive workplaces in the Philippines, blending structural engineering, environmental design, and landscaping to create a bespoke building driven by extensive environmental analysis.
