Trinity College, with its eventful history in Sri Lanka's education landscape, displays a significant Boarding system, integral to its functions. Among the boarding houses, Alison House, the second addition after Napier House, played a crucial role in accommodating the growing student population at the time the Boarding system was in high demand

However, over time, these historical houses have fallen into a state of disrepair, requiring a upgrading effort to restore their former glory and recapture the excitement of being a boarder at Trinity.

By the turn of the century, Alison House had succumbed to neglect, due to lacking proper care, renovation, and restoration. The T150 infrastructure development committee, recognizing the need for a transformative change, made a firm commitment to give Alison House a complete facelift.

The restoration efforts focused on several key infrastructure improvements. Room-based design was implemented to ensure varying capacities, ranging from a maximum of six boarders to a minimum of one per room. Each boarder now enjoys an individual study area with a bunk bed overhead. Common areas were revamped to feature flexible and convertible spaces with loose furniture, catering to diverse needs.

Enclosed study rooms were designated for tutoring, while separate areas provided spaces for leisure. Internal access between floors was enhanced with the addition of stairs. Adequate toilet and washroom facilities were installed on each floor, ensuring convenience for the boarders. The incorporation of skylights allowed for the introduction of natural light, creating a more vibrant and inviting atmosphere.

The primary building materials utilized included timber and steel, contributing to both aesthetic appeal and structural integrity, making the final construction have the look-and-feel of a small boutique hotel

Notably, the Alison House Restoration Project received special donations from the Trinity alumni who were part of the 1976 to 1981 leavers. The Trinity150 Alison House Restoration Project Fund reflects the collective dedication of these alumni, ensuring that Alison House stands as a testament to Trinity's commitment to its heritage while providing a modern and attractive living space for boarders.

As part of the T150 initiative, Trinity College undertook another significant infrastructure development project, resulting in the construction of the Abeyratne-Jeyaraj Complex. The newly constructed Classroom block, fondly referred to as the "AJ" block, was officially commissioned during a soft opening on 12th August 2021. The occasion held deep significance, bringing back memories of two esteemed educators, late Hilary Abeyratne and Paul Jeyaraj, who dedicated themselves to the development of both students and the college.

The soft opening ceremony was graced by Mr. Paul Jeyaraj, the College Executive Council (CEC), and a select group of representatives. The "AJ" block serves as a tribute to the lasting contributions of these two renowned educators. .

This new addition to the college infrastructure effectively addressed the shortage of classrooms for Advanced Level (A/L) students. The Abeyratne-Jeyaraj Complex boasts seven purpose-built classrooms equipped with modern amenities. In addition, the building features modern sanitary facilities catering to both staff and students. The inclusion of cafeterias and a multi-purpose open terrace further enhances the functionality of the complex, providing space for various activities such as competitions, award events, and social gatherings.

During the opening ceremony, the principal expressed immense joy, referring to the occasion as a significant milestone. He emphasized that the new building stands as a gift to the students, proudly declaring it as a creation "by Trinitians for Trinitians." The Abeyratne-Jeyaraj Complex not only fulfills immediate educational needs but also symbolizes the ongoing commitment of the Trinity community to enhance the learning environment for generations of Trinitians to come.

Trinity College, standing as a leader of education in Sri Lanka with an illustrious history, has witnessed many generations of students within its revered halls. A significant component of its legacy is attributed to the Boarding system, an integral part of campus life that flourished in the past. Among the boarding houses, Napier House holds a special place, being the first to open its doors at Trinity.

In 1898, the visionary principal Rev H. P. Napier-Clavering constructed the first official Senior Boarding House, a landmark that would later bear his name—Napier House. Recognizing its historical and cultural significance, UNESCO has declared Napier House a conserved structure within the world heritage city of Kandy.

The passage of time had cast a shadow on this historical premises, prompting a realization that the old excitement of boarding life at Trinity need to be rekindled. The Board and the Architecture and Old Boys Committee (A&OC) joined forces few years ago in view of the forthcoming T150 celebrations, on the restoration of Napier House and the beautification of its surroundings in preparation for the landmark celebrations.

However, this restoration project became not a mere return to the past. Instead, a thoughtful reclassification of Napier House as a multipurpose study area, breathing new life into its timeworn walls. The plan unfolded with the conversion of the first floor into a dynamic space—comprising classrooms, labs, and meeting areas, designed with movable partitions for flexibility in usage. Meanwhile, the ground floor, with its historical echoes, underwent renovation to continue functioning as a dining hall and kitchen.

This elaborate project went beyond aesthetics. It strived to stabilize and preserve the architectural integrity of Napier House, infusing it with more light and ventilation where needed. The restoration was not merely a stand-alone effort but a strategic step toward potentially reviving the historic building for new age education demands.

The Trinity community with hopeful anticipation, believe that the work done on Napier House will stand as a testament to preservation and innovation, ensuring the building's longevity until a more elaborate boarding house restoration project is embarked upon at the right time. The success of this venture rests on the support and enthusiasm of the Trinity community.

Amidst religious blessings and an intense sense of nostalgia, Napier House was ceremonially commissioned on July 6, 2022. The ceremony, attended by religious representatives, staff, and old boys who fervently supported the project, marked a pivotal moment in Trinity's journey—a commitment to preserving its history while embracing a future where Napier House stands not just as a remnant of the past but as a vibrant hub of learning and community development.
