Broad experience in real estate and business in Mexico

At Tantum we bring real estate development and construction together so that we can see each project through from end to end: from spotting the opportunity, the architectural design and the capital structure, to running the site, quality control and the final sale.

Our strategic construction partner is Tantum Real Estate (TRES); we run the building work jointly with them.

Depending on what a project needs, we can act as developers, investors, advisors or specialist service providers, in sectors ranging from hotels and hospitality to residential, education and industrial.

We are based in Mexico City, and from there we run projects across the country.

One counterpart across all four stages

Every project starts by understanding in depth what the people who will live in or use the building actually need. We then look at the goals and incentives of everyone involved, clients, partners and investors alike, so we can design and deliver a proposition that works for all of them.

Concept and master plan

We are involved from the outset: validating the opportunity, shaping the concept and the master plan, including the architectural brief and the coordination of architecture and engineering firms for the construction documents.

Compliance and permits

We make sure every document is legally sound and handle all the permits and licences end to end. We run due diligence, market studies and feasibility analysis from the earliest stages, so the ground is solid before any money is committed.

Financial structuring and planning

We help design the investment vehicle, structure the capital between debt and equity, secure funding and bring partners and co-investors together. We model the project's returns so that every financial decision is aligned with the profitability targets from day one.

Delivery and handover

We are the link between the project and its construction. We coordinate and supervise the building work with specialist contractors, managing the budget, the programme and the quality standards.
