The concept
A Steel Frame home: a steel structure designed for Baja.
We take the construction method used in the United States — steel structure, reinforced walls, wood cladding — and adapt it to the heat, sun and humidity of Baja California Sur. The result: a firm, efficient home with character, built in weeks, not years.
01
Steel structure
14-gauge steel tube (PTR) welded to plates anchored into the concrete slab. It does not rot, termites cannot eat it, and it stands up to the local climate.
02
Treated, sealed wood
Cured plywood, moisture-resistant and termite-repellent, with joints sealed in exterior-grade silicone and oil-based thermal paint.
03
Sand-finish roof
5/8" plywood roof deck with a 3.5 mm sand-finish coating on a single slope: it drains well, prevents leaks and, with maintenance, can last over 30 years.
04
Protected interiors
1/2" drywall and, in the bathroom and kitchen, moisture-resistant boards (DensGlass) with reinforcement for cabinets and shower.

Customization
Your home, your way
The Arena model is the starting point. These are some of the upgrades we have already designed and priced. Pick the ones you like and we will prepare a detailed budget.
01
Heat control
Spray polyurethane foam insulation on roof and walls to reduce heat transfer.
02
Gable roof (Balandra)
Raises the roof and creates an attic of about 40 cm, ventilated with exhaust fan and air intakes.
03
Reinforced 5/8" walls
Walls use 1/2" plywood. You can upgrade to reinforced 5/8", with extra layers and an asphalt-paper barrier, for more strength and better acoustics. (The roof already includes 5/8".)
04
Double-glazed windows
Two thicker panes in a reinforced aluminum frame with airtight sealing.
05
Air conditioning
Mini-split package with dedicated electrical installation: living room, bedrooms and ceiling fan.
06
Tailored installations
Cistern, water tank, water heater, septic tank, booster pump, kitchen counter and sliding door.
Every change is quoted and authorized in writing before work begins, and cannot compromise the structural integrity of the home.
Upgrades explained
How the upgrades work
What each upgrade you can choose for your home looks like on the inside.
Roof: Arena or Balandra
The single-slope roof (Arena) can become a gable roof (Balandra), raised to create an attic of about 40 cm.
Reinforced walls
Plywood layers (5/8" and 1/2"), an asphalt barrier and 1" polyurethane foam help reduce the heat reaching the structure.
Double-glazed windows
Two thicker panes with a small separation in a reinforced aluminum frame.
Ventilated attic
A central exhaust fan pulls hot air out while air intakes bring fresh air in.

Transparency
What to know before you sign
We prefer everything to be clear from the start. This summarizes the contract and its technical annex; if there is any difference, the signed contract prevails.
Build period
The period is 50 business days counted from the initial payment and from the lot being leveled and formally handed over. It may be suspended or extended due to missed payments, requested changes, weather, unforeseeable events or force majeure.
Price and quote
The published price is for the base model plus VAT and applies to construction in La Paz. Outside La Paz, transport and installation costs are added, and each customization is quoted separately. Prices are indicative until an authorized, current quote exists.
The lot
The lot must be yours, free of liens, leveled and fit to receive the concrete slab. If it needs leveling, fill or a special foundation, that is quoted as additional work.
Permits and utilities
Permits, licenses and construction procedures are the client's responsibility. We deliver the floor plan; your architect or agent processes the license. Contracting and connecting power, water and sewer are not included, nor is the meter base or water meter. During construction, power and water supply is required; if unavailable, an additional charge applies for generator and water.
Scope of the model
The quote includes what is described in the technical annex. It does not include closets, built-in kitchen, air conditioning, special windows, perimeter walls or equipment unless listed in the authorized quote. Images and renders are illustrative; reasonable variations in tone, texture and minor dimensions may occur.
Climate and thermal comfort
The home is lightweight and designed for the regional climate. For extra comfort during the hot months we recommend the heat-control package (insulation, ventilation and mini-splits), which you can add to your quote.
Voice, data and internet
No underground voice and data conduits are left in place. The only underground preparations are for water and drainage. Internet and data are installed with surface conduit or wirelessly.
Structure and changes
The model is not designed for vertical growth (a second floor), and altering structural elements or drilling or adapting walls without technical authorization is not allowed. Doing so voids the warranties. The builder may reject changes that pose a technical or structural risk.
Site access
For safety, client access to the site is restricted: it is allowed during structure erection, wall cladding, the start of floor finishes and the final handover, with prior notice. Outside suppliers may not be brought in, and equipment may not be installed before handover.
Warranties
We include warranties of up to 7 years on materials (per each manufacturer) and 1 year on the home for hidden defects or leaks.
Home insurance
Insurance is optional. The home can be insured with HDI Seguros with coverage for the building, contents, hydrometeorological events, glass, appliances, family liability, debris removal and personal accidents at home. Coverage, sums insured, deductibles and exclusions depend on the policy in force; insurance is separate from the construction warranties.
Maintenance
Durability depends on maintenance: periodic painting, yearly fumigation and sealant replacement. With proper maintenance the sand finish can last over 30 years. At handover we give you a maintenance manual and the areas suitable for anchors and installations.
Intermediary
Inversiones Baja Sur acts as an intermediary: it coordinates the commercial and administrative relationship between client and builder. Technical execution of the work is the builder's responsibility.
FAQ
What people ask most
Can the home be insured?
Yes, optionally. We work with HDI Seguros to insure the home (homeowners insurance) with coverage for the building, contents, hydrometeorological events such as hurricanes and flooding, family liability and more. You can download the coverage sheet in the insurance section. Coverage is subject to the terms, conditions, deductibles and exclusions of the policy; your advisor explains scope, cost and term.
Why a Steel Frame home and not block?
It is a faster, lighter and more precise system: it is built in 50 business days, the steel frame does not rot or attract termites, and the concrete slab ensures a firm base. It is a method our builder has used for years in the United States.
Does it handle Baja's heat, sun and humidity?
It is designed for it: treated plywood, sealed joints, thermal paint and a sand-finish roof. For extra thermal comfort we offer insulation, a ventilated roof, double glazing and mini-splits.
Can I change the layout or finishes?
Yes, within structural limits. You can choose exterior color, sliding door, equipment, air conditioning and more. Everything is quoted and authorized in writing before work begins.
Do I need to already own the lot?
Yes, the lot must be in your name, free of liens and leveled. If you do not have one yet, we can help you find it: we also sell land in Baja California Sur.
Which areas do you build in?
The base price applies in La Paz. We also build in Todos Santos, El Pescadero, El Sargento, La Ventana, Los Planes, San Antonio and El Triunfo, with additional transport and installation costs.
Can I see the home before deciding?
Yes. We have virtual tours, and you can visit builds in progress at the permitted stages. Request it in the form.
