House construction in Mahahual
Design, licence and construction with a single contractor, for clients who live outside Mexico.
Mahahual is a fishing village turned cruise port on the Costa Maya, with Banco Chinchorro offshore and mangrove at its back. Building here means building on a narrow coastal strip, with limited networks and the full force of the Caribbean.
Between the reef and the mangrove
The town sits on a strip of sand between the sea and a band of mangrove. The beachfront is federal maritime zone (ZOFEMAT) and the mangrove is protected by NOM-022, so the buildable area of many lots is smaller than the deed suggests. We survey the lot and both boundaries before drawing anything.
Off-grid by design, not by accident
Outside the town centre, municipal water and drainage are limited, and power cuts are not rare. A sensible Mahahual house includes a cistern sized for several days, a treatment plant, solar with storage for essential loads and, ideally, rainwater capture. We budget these from the start instead of discovering them at the end.
Dean taught the coast what wind means
Hurricane Dean made landfall near Mahahual in 2007 as a category 5 storm. Since then, designs here take wind and storm surge seriously: raised ground floor, reinforced concrete structure, tied slabs, protected openings and 316 stainless for anything exposed. The salt reaches everything on this strip.
Realistic budget and programme in Mahahual
The range here is MXN 16,000 to 29,000 per m² (roughly USD 880 – 1,600/m²). Materials come mostly from Chetumal, about two hours away, which keeps freight reasonable, but the off-grid systems and the marine-exposure specification add a full step over an inland house.
A typical programme is eleven to fifteen months for 150–300 m², including the federal maritime zone and mangrove reviews where they apply. We avoid concrete pours and roof work in the peak of the hurricane season whenever the programme allows.
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 Mahahual: what it imposes on the project
- Municipality: Othón P. Blanco
- Environmental regime: ZOFEMAT + NOM-022 (mangrove) + municipal
- Ground: coastal sand over limestone, peat near the mangrove
- Water table: high
- Salt exposure: very high
A narrow strip between reef and mangrove: federal beach zone in front, protected wetland behind and limited services in between.
- Locate the ZOFEMAT line and the mangrove edge on a topographic survey before buying; they define the real buildable area.
- Budget water, power and treatment as part of the house, not as optional extras.

Frequently asked questions
Is there water and electricity in Mahahual?
In the town centre, yes, with frequent cuts. Further along the coast it is limited or absent, so houses rely on cisterns, solar with batteries and their own treatment plant. We design them as part of the project.
Can I build on the beach in Mahahual?
Not on the first 20 metres from the high-tide line, which is federal maritime zone and needs a concession for any use. The house goes behind it, and behind the house the mangrove is protected; the buildable band is what lies between.
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.
