Design, permits and turnkey construction — with price and programme in the contract
A villa in Tulum is decided in three places: the environmental file, the karst under the lot, and service feasibility. The render comes after. We take the whole project, from concept to handover.

In the Tulum municipality practically every project goes through the state environmental authority, and its resolution precedes the municipal licence. That puts three to six months before work can start, against four to ten weeks inland in Playa del Carmen. It is not an obstacle, it is a date: ignore it and you end up with a paid-for construction set and a lot standing idle.
The ground is karst under low jungle. Voids are invisible from the surface, and a cavern found after the pour costs more than the entire soil study. The vegetation inventory weighs too: authorised clearing and flora rescue go into the file, and the existing trees usually move where the house sits within the plot.
The water table is mid-depth, which allows conventional foundations and, where the study confirms it, an absorption well rather than a treatment plant. That is a real advantage over the coastal strip, where the water sits very high.
The chukum. Applied well it is waterproof and ages with character; applied badly it stains in the first rainy season and gets redone in full. It is specialist labour, not a finish improvised with whoever is on site.
Roof waterproofing. In the tropics a flat slab is a system — falls, parapets, coving, outlets and a flood test before the finish — not a coat of sealant. A leak at three years destroys everything below it.
The steel. Inland 304 holds; near the sea it pits within two years. Hardware, window systems and anchors are specified by the real distance to the coast, not from a catalogue.
Across much of the municipality there is no sewer network, and in several regions the CFE connection is resolved lot by lot. That means your own treatment plant, water storage and, depending on the case, a capacity increase, a transformer or a line extension at the owner’s cost.
It is not an extra: it is a line in the first budget, and it is the figure that most often breaks a price quoted per square metre. We verify service feasibility before pricing the house, not after signing for it.
Design and construction under one contract. That removes the classic conflict between whoever draws and whoever builds, and with it the gap the client usually pays for at the finishes stage.
Fixed price, fixed programme and a payment schedule tied to progress. Changes are documented with a price before they are executed. Weekly reporting with photographs, because most of our clients do not live here: we have worked with foreign owners since 2008, with fideicomiso, payment from abroad and video handover when they cannot travel.
The state SEMA sets the calendar; the environmental file is the rule, not the exception.
Compare with the other 40 zones in the zone checker.
The range is wide and it is set by the specification rather than the size. Pool, automation, bespoke joinery and electrical backup move the budget more than twenty extra square metres. We give a fixed price after the concept design and the room programme.
With the state SEMA, three to six months for a complete, well-assembled file. On the coastal strip, where SEMARNAT and ZOFEMAT join, six to twelve. We file it in parallel with developing the design so the window is not lost.
Yes, and it is common. Treatment plant, water storage and own generation or solar with backup. What is not viable is discovering it mid-build: feasibility is verified before the budget.
Yes. Weekly photo reporting, video calls at milestones, payment by transfer and a power of attorney for a representative when something has to be signed. That is how most of our clients work.
Yes, with in-house joinery and metalwork. Chukum, polished concrete, tropical hardwood and local stone, specified at design stage so the result does not depend on what happens to be on site that day.
