The DAIF SABAH (2023) redevelopment project at SK Tambulian upgrades the primary school into a safer, more functional, and future-ready learning environment. This improvement enhances both academic and support facilities to better serve students, teachers, and the wider community.

Central to the project is the three-storey Administration Block, which supports efficient school management, along with the two-storey Academic Block that provides improved classrooms designed for a more engaging learning experience.

Additional facilities include a two-storey Amenities Block with a surau, offering spaces for daily activities and religious functions, and a single-storey Pre-School Block dedicated to early childhood education.

Supporting structures such as the single-storey Guard House and Waste Management Building (Rumah Sampah) ensure a safe and well-maintained campus environment.

The redevelopment also features a covered open Multipurpose Court (GSTB), creating a versatile space for sports, assemblies, and community activities.

Overall, these upgraded facilities contribute to a more organized, comfortable, and effective school environment, strengthening SK Tambulian’s role as an important educational center in Kota Belud.
