One system. Every certainty.
FRESH® is a modular building system by Gatun Lake Construction — a solid steel frame and insulated panels, engineered for Panama, delivered at a fixed price and a fixed timeline.
Build faster, smarter, and with greater flexibility.
The FRESH® Building System combines innovative modular construction with a lightweight prefabricated structure, creating high-quality homes that perform exceptionally in virtually any environment.
Build smarter, faster, and greener with the FRESH® KOP System. The system combines prefabrication with intelligent engineering. Using a modular Kit of Parts (KOP), homes are manufactured efficiently and assembled quickly on-site — reducing construction time, waste and uncertainty.
The system is built on two pillars:
- FRESH® Steel Structure: a durable, lightweight frame engineered for strength, stability and challenging terrain.
- FRESH® Insulated Panels: high-performance panels that enhance comfort, energy efficiency and long-term performance.
Build Where Others Can't
Remote locations, steep terrain, and challenging sites become buildable thanks to FRESH®'s lightweight modular design and minimal foundation requirements.
Build Up To 50% Faster
Prefabricated components and efficient assembly dramatically reduce construction time, getting you into your new home sooner.
Off-Grid Ready
Designed to integrate seamlessly with solar power, water treatment, and self-sufficient living systems — wherever you choose to live.
Built for Extreme Conditions
Engineered with a high-strength steel structure and advanced materials to withstand earthquakes, storms, humidity, and harsh climates.
Superior Insulation
High-performance FRESH® KOP Panels keep your home cooler in warm climates and warmer in cold climates while significantly reducing energy costs.
Small Ecological Footprint
Smaller foundations, less material waste, and a highly efficient prefabrication process help preserve the natural beauty of your land.
Predictable Costs
Standardized designs and factory-controlled production minimize surprises, keeping your project on schedule and within budget.
Low Maintenance Living
Durable, corrosion-protected materials and smart engineering ensure long-term performance with minimal upkeep.
Built for Panama, in numbers.
What the FRESH® system is made of and what it is designed to handle — earthquakes, storms, salt air and tropical heat.
| Structure | Prefabricated galvanized steel Kit of Parts (KOP), engineered with UTP and assembled on site |
|---|---|
| Corrosion protection | Alu-Zinc interior and exterior cladding plus a two-layer marine-grade industrial coating, made for coastal humidity and salt air |
| Earthquakes | A flexible steel frame that absorbs movement instead of cracking like rigid block and concrete |
| Storms | Designed for seismic and hurricane loads, with the structure anchored to a foundation sized for the site |
| Insulation | Friopanel 75 mm HP-PUR F insulated panels with a U-value of 0.11 W/m²K, against 1.0–2.0 W/m²K for a 15 cm hollow-block wall |
| Energy use | Air-conditioning energy up to 70% lower than a comparable concrete-block home (estimate) |
| Termites, rot and mold | Steel does not rot or feed termites; the materials resist UV, moisture and biological degradation |
| Foundation | Minimal foundation that adapts to sloped and uneven lots; standard layout based on typical soil conditions |
| Build time | Structure assembled on site in weeks; a typical concrete-block home in Panama takes 9–18 months |
| Engineered lifespan | 50+ years with the recommended maintenance schedule |
| Permits | Technical drawings for the building permit and occupancy certificate are included |
| Off-grid | Ready for solar power, water treatment and self-sufficient systems |
Energy figures are estimates based on comparable house sizes in Boca Chica and Boquete. Exact specifications are confirmed per project in your fixed proposal.
How it compares to traditional construction.
Most homes in Panama are built from concrete block. Here is how the FRESH® system differs, side by side.
| FRESH® | Concrete block | |
|---|---|---|
| Build time | Weeks, on a fixed timeline | 9–18 months, weather-dependent and often delayed |
| Price | Fixed price, engineered packages | Budget overruns and scope creep are common |
| Earthquakes | Flexible steel frame absorbs movement | Rigid block and concrete crack under movement |
| Salt air and corrosion | Alu-Zinc cladding plus two-layer marine coating | Rebar and block vulnerable to corrosion over time |
| Insulation | U-value 0.11 W/m²K | U-value 1.0–2.0 W/m²K (15 cm hollow block) |
| Termites and rot | Steel does not rot or feed termites | Timber elements need treatment and inspection |
| Site impact | Lightweight system, small foundation, minimal disruption | Heavy machinery, large foundations, lots of waste |
| Remote and sloped lots | Designed for remote, sloped and off-grid sites | Often difficult or unfeasible because of logistics |
| Off-grid | Ready for solar, water treatment and ventilation | Complex to plan and integrate |

Factory Production & Site Preparation
While your FRESH® home is being prefabricated, the construction site is prepared — foundations and utility connections — so both processes move forward efficiently.

5
Assembly & Handover
Your FRESH® home is assembled on-site and completed according to the agreed specifications. After final inspections, we hand over a finished, move-in-ready home.
Fifty years, four simple habits.
The 50+ year engineered lifespan assumes this recommended schedule.
| When | What |
|---|---|
| Every year | Surface inspection and cleaning |
| Every 3–5 years | Touch up the coating where needed |
| Every 10–15 years | Reapply the full protective coating in high-exposure areas |
| Every 15–20 years | Full recoating for maximum longevity |
The honest answers.
A prefabricated galvanized steel frame with Alu-Zinc cladding and a two-layer marine-grade coating, enclosed in Friopanel insulated panels — engineered to resist earthquakes and storms, with a 50+ year structural lifespan.
Because the steel Kit of Parts and panels are prefabricated, the structure is assembled on site in weeks rather than months, on a fixed timeline you get in writing.
The steel uses Alu-Zinc cladding plus a two-layer marine-grade coating specifically to resist coastal humidity and salt — the same system standing today at our Coco Beach villas.
Almost always. The lightweight steel needs only a minimal foundation and adapts well to slopes, and the system is off-grid ready with optional solar and water treatment.
Yes — every FRESH® home is quoted at a fixed price and timeline before you commit, with included scope and any options quoted clearly, line by line.
Yes. The steel structure is designed to flex and absorb movement without losing structural integrity, where rigid block and concrete tend to crack. The engineering was developed with UTP for Panama’s conditions.
The system is designed for seismic and hurricane loads, and each home is anchored to a foundation sized for its site. Panama sits mostly south of the hurricane belt, but coastal gusts and heavy rain are designed for.
No. The steel frame does not rot or feed termites, and the panels and coatings resist moisture, UV and biological degradation — a big difference from timber in the tropics.
Friopanel panels reach a U-value of 0.11 W/m²K, against 1.0–2.0 for a 15 cm hollow-block wall. That can cut air-conditioning energy by up to 70%, which for a 120 m² home in Boca Chica is roughly $1,600–1,900 a year (estimate).
An annual inspection and clean, coating touch-ups every 3–5 years, a full recoat of high-exposure areas every 10–15 years, and a full recoat every 15–20 years.
Every FRESH home includes the technical drawings needed for the building permit and the occupancy certificate, and components are produced under strict quality control.
It is built in weeks instead of 9–18 months, at a fixed price, with far better insulation, a frame that flexes in earthquakes, and a much smaller foundation and site footprint.
