Accessible tech-enabled planning, design and financial services for improving housing quality and resilience in LatAm.

The Problem

Over 60% of the population in Latinamerica (270million) build their homes without technical assistance. This generates horizontal and unplanned low-density growth and 100% increase in waste materials, which increases CO2 emissions. Additionally, families end up overspending up to 50%, and living in homes with unsafe structures and poor design layouts.

The Solution

La Firme's platform provides accessible and affordable architecture and engineering services for low and middle income families to design their home and plan their construction. By integrating existing technologies and creating a digital-first architecture service, La Firme is able to reduce the time invested by professionals and, therefore, reduce its costs for the millions of families self-constructing across Latin America.

The solution has three phases:

Site Analysis: Leveraging existing databases to automatically assess the lot, and provide a customized quote.

Design phase: Families share their spatial needs and preferences through the engaging online experience. They choose an architect from pre-filtered options to design their home in three online meetings. Architects receive the previously collected information and templates to work more efficiently.

Delivery phase: Families receive a complete drawing set, a booklet that translates its technicalities and an incremental growth strategy designed to phase construction according to their financial possibilities.

Stats

La Firme has guided 692 families through home construction planning and advisory.

Who does your solution serve, and in what ways will the solution impact their lives?
Our customers are low-to-middle-income families in Latin America—1.8 million households annually—who build or expand homes without professional assistance. In urban Peru alone, 86,000 families build informally each year. We target decision-makers aged 30–55 with variable incomes, prioritizing consolidated urban areas with existing infrastructure. By providing affordable technical oversight, we transform these homes from structural liabilities into high-value assets. Our intervention ensures safer, optimized constructions that prevent overspending and increase property value by an average of 20%. Ultimately, we enable families to build multi-generational wealth through secure, formal housing investments rather than relying on informal, unguided construction.
