Fifty dollars could mean any one of a number of things to you: a tank of gas, a new shirt, a couple of days of groceries, maybe a bet on a local thoroughbred. Or, if you’re thinking long term, it could be the first square foot of your future Mexican beach house. A pad in sunny Rosarito, for example, can be built at $50 a foot (but keep in mind that prices range from $30 to $100 or more depending on materials); the entire process, from spit of sand to dream house, could cost no more than $250,000.

Building rather than buying a house brings with it a number of advantages. First and most obviously, is that you control the process. You’re not stuck with someone else’s idea of aesthetics when you’re starting from scratch. The patio’s too small? Snap your fingers, now it’s doubled. You’d prefer a villa to a bungalow? No problem. You want a tower coming up from the rear bedroom? Done, and done.

Another advantage to building in Mexico is that it usually multiplies the eventual return on the investment. With real estate prices in Mexico eternally on the rise, you can be sure that future appraisals of your house will reveal a structure worth far more money than what you sunk into it. Overseeing the construction also allows you to sidestep other less obvious obstacles to the perfect home, like faulty wiring, low ceilings, and antiquated building techniques.

One example of this is Structurally Insulated Panels, or SIPs, which are a quick, efficient, and inexpensive way to raise a roof.  Structurally Insulated Panels represent the latest in easy construction and green living. The panels have an insulating core (like polystyrene) capped on each side by a surface material like sheet rock, plywood, or metal. The factory-built, precut panels are designed to smoothly fit together, so, when compared with traditional methods, SIP building is a snap. But despite the easy construction, SIP panels are durable, with strength properties similar to that of an I-beam. 

How do the panels lead to lower expenses (and give you more money to spend on, say, a 21-footer to dock in the Sea of Cortez)? It starts with the labor costs. Panels can be as big as 8 x 24 feet, so entire walls can be raised with a minimum of effort. Because SIPs arrive to the site basically ready to use, builders save time that would be spent framing and sheathing. Less time on the job for builders means less time paying construction workers, and more disposable income that you can use to decorate the place.

But even after building is complete, SIPs continue to save money. The panels are virtually airtight, which lowers air conditioning bills, as well as in the rare instance when a heater is necessary in Baja California. Efficiency typically increases by about 50 percent with SIP homes. As far as its green value, the SIPs’ insulating properties help reduce greenhouse emissions. SIPs also consumer fewer resources than do traditional building techniques, and because they’re prefabricated, waste is minimized. If your home qualifies for Energy Efficient Mortgage certification, the appraisal and resale value shoots upward.

If you’re interested in building a house in Mexico, Baja 123 is the agency that can make it happen. All you need is an idea, and about $50 per foot (compared to $200 or $400 in the States). The rest, you can leave to the staff at Baja 123. That means the tricky particulars—knowledge of the building codes, navigating the restricted building areas, connecting with local builders, familiarity with the Spanish word for screw or hammer (tornillo and martillo, for those of you scoring at home)—are taken care of, and all you as home builder need to worry about is where to hang hammock.
