02 / THE ARCHITECT BEHIND NA

Construction experience.
On-site insight.

I’m Nelson Aristizábal. My experience combines residential construction in Argentina with property inspections during emergency response efforts in Colombia.

In Argentina, I worked on luxury single-family homes in gated communities and as a site supervisor on buildings of up to 17 stories in Buenos Aires. Over the course of my work, I supervised more than 100 apartments and took part in various construction stages of more than 20 houses, including the factory production of components for prefabricated lightweight homes.

In Pereira and Colombia’s Coffee Region, I supported communities during the earthquake emergency by inspecting buildings and documenting damage. That experience strengthened my commitment to careful observation, clear records and practical guidance on next steps.

My background in customer service and consultative sales complements this experience: listening to your priorities, explaining your options clearly and helping you make informed property decisions.

05 / FREQUENTLY ASKED QUESTIONS

Clarity from
the start.

How much does a visit or project cost?

Fees depend on the location, floor area, number of stories and deliverables. Share your property details on WhatsApp and you’ll receive a proposal before committing. Visits, reports, cost estimates and specialist studies are priced according to their scope.

Can I request an inspection before buying?

Yes. A visual inspection helps identify visible conditions and questions to resolve before purchasing or taking possession of a new or existing property. The scope is agreed in advance, includes a written report and may include an approximate cost estimate for construction or repair work.

Does the inspection certify structural stability?

The inspection provides a written report with photographs, descriptions of visible defects, recommendations for use and intervention priorities. It helps you understand what needs attention and what to do next. If signs of potential structural concerns are identified, an engineer is brought in to assess them and recommend appropriate stabilization measures. Certification of structural stability requires a specialist structural assessment.

Do you work in Medellín and other cities?

Services focus on Medellín and Valle de Aburrá, including Envigado and Sabaneta. Visits to Pereira and other municipalities can be arranged depending on availability, scope and travel requirements.

Can you also help with the renovation?

Yes. We can prepare a proposal for design, cost estimates and construction support based on your needs. Specialist studies, permit procedures and construction work are itemized separately where applicable.

How do I book, and what should I send?

Message us on WhatsApp with the city, property type, approximate floor area and reason for your inquiry. Share any photos or plans in the conversation. We confirm the appointment directly with you.
