House construction in Bacalar
Design, licence and construction with a single contractor, for clients who live outside Mexico.
Bacalar is not Caribbean coast: it is a freshwater lagoon with living stromatolites, and that difference completely changes what a house is required to do. Here the criterion is not salt resistance, it is zero discharge.
Stromatolites: why zero discharge is not negotiable
The lagoon’s stromatolites are living microbial colonies, extremely sensitive to nutrients and detergents. Any input of grey or black water damages them, and the damage shows in years, not decades. So the design starts from a correctly sized treatment plant, irrigation with treated water and a choice of cleaning products that forms part of the house manual.
The lagoon frontage has its own rules
The setback from the shore, runoff management and lakeside vegetation enter the file, with SEMARNAT on the environmental side and the Bacalar municipality on the licence. The water table beside the lagoon is very high: platform, foundation and pool are resolved accordingly, and a basement is not an option.
No salt, but humidity and distance
The good news: with no marine exposure, 304 stainless and standard hardware hold, which makes the specification cheaper than on the coast. The trade-off is distance. Bacalar sits far from the corridor’s supply centres, so freight and the availability of specialist trades weigh more heavily on both budget and programme.
Realistic budget and programme in Bacalar
The range here is MXN 11,500 to 23,000 per m² (roughly USD 630 – 1,250/m²), the lowest we quote, because without marine exposure the specification for hardware, window systems and anchors drops a full step. What rises is freight from the corridor and the cost of bringing in specialist trades who do not live in the municipality.
A typical programme is ten to fourteen months for 200–350 m². The treatment plant and runoff management enter the budget from day one, not as an extra at the end: on a lagoon frontage they are the condition of the licence and the only way not to damage what makes the property valuable.
What we deliver: design, licence and construction in one contract
We work turnkey. Lot survey and soil study, concept and executive design, licence filing with the responsible engineer, construction with our own crews, services, finishes, pool and landscaping, and handover with as-built drawings and equipment manuals. One contract, one point of contact and a programme that is not split across five suppliers blaming one another.
The budget comes out as line items with quantities and unit rates, not as a single lump figure. That way you can see where the money sits and what happens if a finish changes mid-build.
How it works when the client does not live in Mexico
Most of our clients are abroad while the house is being built. The system is designed for that: a weekly report with dated photographs, a fortnightly video call from site, a live budget where every change is signed off before it is executed, and payments against verified progress rather than against the calendar. We work in Spanish, English, German, French, Russian and Chinese.
If the property sits in the restricted zone, a bank trust (fideicomiso) is the usual holding vehicle; we coordinate with the notary and the bank so that the construction file and the ownership file advance in parallel.
The ground in Bacalar: what it imposes on the project
- Municipality: Bacalar
- Environmental regime: SEMARNAT (lagoon and stromatolites) + municipal
- Ground: limestone with lake sediment
- Water table: very high next to the lagoon
- Salt exposure: low
A freshwater lagoon with living stromatolites: zero discharge, a setback from the shore and restricted chemicals on the lakeside strip.
- Federal SEMARNAT filing: the environmental resolution is the project’s critical path. Budget 4–8 months before the first excavation.
- Very high water table: forget the basement. Compacted fill platform, raft foundation and negative-side waterproofing.

Frequently asked questions
Why is water treatment so strict in Bacalar?
Because the lagoon holds living stromatolites, microbial colonies damaged by nutrients and detergents. Zero discharge is not a design preference: it is the condition for the lagoon frontage to stay what makes the property valuable.
Is it cheaper to build than on the coast?
On specification, yes: without marine exposure, 304 stainless and standard hardware hold. What rises is freight and the availability of specialist trades, because Bacalar sits far from the corridor’s supply centres.
Do you work on a fixed budget or on a cost-plus basis?
A line-item budget with unit rates and a contracted amount. Any change is priced and signed before it is executed, and payments go against verified progress on site rather than against calendar dates.
What warranty do you give on the finished house?
One year on services and finishes and five years on structure and waterproofing, delivered with as-built drawings, technical datasheets and manuals for the installed equipment.
