Architect Builds Recycled Shelters for Stray Dogs in Pasto, Nariño
Jeison Castillo, an architect based in Pasto, Nariño, has gained attention for his initiative to build shelters for stray dogs using recycled materials, as reported by EL TIEMPO. The project, which began as a personal effort, has since mobilized community support and drawn the attention of local authorities.
How Jeison Castillo’s Project Began
Castillo, known online as @ofus_visual, started constructing shelters for stray animals after noticing their vulnerability to harsh weather conditions. His first project involved building a shelter for a dog named Osito in the Champañá neighborhood. The structure, made from recycled materials, was transported to the site with assistance from local police, according to Alcance Digital.
Castillo emphasized that the initiative is independent, with no involvement from foundations or sponsors. “I’m an architect who decided to use my profession to help those without a voice,” he stated on Instagram, as cited by EL TIEMPO.
Community Response and Expansion
The project quickly gained traction on social media, with users sharing donations and materials to support Castillo’s work. Community members also participated in construction efforts, according to Alcance Digital. Castillo later reinforced the shelter for Osito by paving the area and installing a permanent structure to prevent theft.
Castillo’s efforts extend beyond shelters. He has designed feeding stations and other protective spaces for stray animals, using sustainable materials. “The goal is to address both animal welfare and environmental sustainability,” he said in an Instagram post, as reported by EL TIEMPO.
Engagement with Local Authorities
To scale the initiative, Castillo presented his project to the Mayor’s Office of Pasto. The move aims to formalize support for stray animal care and promote sustainable construction practices, according to Alcance Digital. Local officials have not yet commented publicly on the proposal.

Castillo continues to document his work on Instagram, urging followers to contribute materials, funds, or volunteer time. “Every effort counts,” he wrote, as shared by EL TIEMPO.
Why the Initiative Matters
Stray animal populations in Colombia face challenges including harsh climates and lack of shelter. Castillo’s approach combines humanitarian aid with environmental responsibility, using waste materials to create functional spaces. Similar projects in other regions, such as Bogotá’s animal shelters, have also prioritized sustainability, according to EL TIEMPO.
Experts note that community-driven efforts like Castillo’s can complement government programs. “Local initiatives often address immediate needs more effectively,” said Dr. María López, a urban studies professor at Universidad Nacional de Colombia, in an interview with EL TIEMPO.
