    The slip-form, rammed- earth wall construction process is projected as an opportunity to transfer technology to locals/soldiers. The subsequent training tasks are planned at an early design stage called “fabrication and training design”. Here, various components of the system and mould-work are delineated, the fabrication/training tolerances are defined, the production site (training ground), minimum module and sample labour gang (for training) are established, and fabrication steps are laid out.

    3D view of the proposed library: The single-story building mass spans nonchalantly across the landscape, touching the earth as lightly as possible. The building informally wraps around an internal courtyard that is also an extension of the external landscape. The placement of the building on site retains all existing trees, while its linear footprint allows optimized natural ventilation and brings in sunlight to all internal rooms; rammed earth walls provide thermal mass.

    The army's human resource is assimilated for social building through carefully planned, on-site training initiatives. This reduces immediate labour costs and produces a skilled workforce, whose training expenditure is internalized within the project, thus saving on social cost. Project update November 2015.

    “You can’t design a delicate building if you plan to build as we did here. You have to design the building and the process with plenty of tolerance. The process must be robust, flexible, and adaptable – and be able to withstand many interventions”. – (l-r): Ganga Ratnayake and Milinda Pathiraja, Sri Lanka

Following over 25 years of civil war, the reintegration of young soldiers is one of the great challenges facing Sri Lanka. This Community Library retrained a labor force geared for combat with building skills to equip them for post-military life.

The slender building sits lightly in the landscape and wraps around an inner courtyard, taking full advantage of cross ventilation and daylighting. Rammed-earth walls and recycled materials reduce costs and the ecological footprint.

Community Library Builds Skills and Social Reintegration in Sri Lanka

Completed in 2025, the project in the rural town of Ambepussa near Colombo supports the reintegration of former soldiers into post-civil war Sri Lankan society. Many of the young men involved come from disadvantaged socio-economic backgrounds and receive training in construction through hands-on participation in building public infrastructure—most notably, the Community Library in Ambepussa.

The slender, courtyard-focused library respects the existing landscape, preserving trees and sitting lightly on the site. Its design maximises natural ventilation and daylight, while rammed-earth walls and recycled materials minimise the building’s environmental footprint.

Beyond providing a public facility, the project has also helped raise the standard of construction in Sri Lanka. It highlights the value of skilled labour—not only for the success of architectural work, but also as a pathway for individuals seeking careers in the construction industry. “Architects have a responsibility not only to the profession and the client, but also to society—it’s our goal to bring these dimensions together in our work,” the architect noted.

His work including the Holcim Foundation Awards prize-winning Community Library in rural Ambepussa illustrates his focus on a form of architecture that not only produces spaces and constructed artifacts – but that also builds capacities and human capital.

Jury Appraisal

The Ambepussa Community Library tells a powerful story—not just of a building, but of a society laying the foundations for a more inclusive and sustainable future. The project’s conceptual clarity is immediately apparent: the juxtaposition of weapons and tools symbolises a deliberate transformation, turning a discharged army into a motivated workforce in service of the public good.

The subsequent training tasks are planned at an early design stage called “fabrication and training design”.

Project update November 2015.

The jury praised the project for addressing both the process and product of architecture—celebrating “building” as both verb and noun. More than a symbolic gesture, the entry outlines concrete steps to achieve its goals, including vocational training, logistical planning, and the application of sustainable construction techniques. The authors recognised the untapped potential of military organisation and skills for peaceful civic purposes, using the building of a library to foster social bonds and heal collective wounds.

The result is not only a public facility for education, but also a structure embedded with broader value: building capacity, fostering development, disseminating knowledge, and strengthening community. The jury greatly appreciated this holistic approach and its clear translation into a tangible and lasting contribution to society.

Project Updates

Statements of Sustainability

  • To address the widespread de-skilling of the construction workforce and promote the army’s role in post-war reconstruction, this project uses real building projects as training grounds for skill development. Training tasks are planned early and integrated into the design—an approach that could inform broader policy for capacity-building across the industry. The project also features Sri Lanka’s first large-scale use of rammed-earth for a building of this type, demonstrating innovation in material application.

  • For soldiers facing psychological, social, and economic hardship, the building process offers a pathway to career development and social reintegration. The completed library becomes a shared resource for both soldiers and the local community—especially school children and women, who have long been deprived of such access. For all involved, the project offers opportunities for cohesion, learning, and personal growth.

  • Rammed-earth was sourced from an adjacent site being excavated for a playground. Reused steel from old factories and timber railway sleepers from a nearby station form the structure and flooring. These renewable, recycled, and low-emission materials are complemented by sustainable environmental planning, including cross and stack ventilation and abundant natural light—reducing the building’s life-cycle costs.

  • By integrating on-site training, the project absorbs labor costs while producing a skilled workforce. Training expenses are internalised within the project, resulting in economic efficiency. The use of recycled and low-tech materials reduces both construction costs and long-term environmental impact. Programmatically, improved access to knowledge becomes a vehicle for addressing ethnic divisions and promoting sustainable economic development.

  • The building’s layout respects all existing trees, aligns with the scale of neighbouring structures, and enhances the landscape’s natural beauty. A network of formal and informal reading platforms is arranged throughout and around the building. The spatial sequence unfolds as an immersive experience of changing volumes, framed views, and fluid transitions between indoor and outdoor spaces.
