The challenge of building a wooden mountain cabin with helicopter


Published in Barcelona  16.A wooden mountain refuge designed following bioclimatic criteria, prefabricated and assembled by helicopter. A  100% removable and 100% self-sufficent cabin developed as a new NOEM CONCEPT


Estanilles Refuge is located at 2200 m above sea level in a remote valley of the Natural Park of the High Pyrenees inaccessible to traffic. The refuge is part of a program that aims to make possible the coexistence of brown bears in the Pyrenees with local populations and traditional trades of livestock.

The initiative, promoted by the ONG Acciónatura, wanted to give to the pastors a shelter with a certain comfort to a very demanding working conditions in a remote area of ​​high mountains, during the four months of summer hard season program called “Grouping herds”.

The program consist to hire one or more pastors to take care and make groups of sheeps of several owners in the area in height during the summer months, protecting them against the possible presence of bears in the area, using mastiffs and sometimes electric pastors. The action, as a part of a larger project of bear conservation contributes both, to preserve a traditional job, to slow down the depopulation of rural areas and especially to demonstrate the possibility of coexistence of man kind and the brown bear. This is a pilot project that can be perfectly replicated in other valleys of the Pyrenees.

Green building construction consist in a module designed and prefabricated wooden workshop of 25m2 assembled into its final location by helicopter responsible for raising prefabricated wooden panels to the place.

Accessibility issues and the possibility of joining a prefabricated shelter workshop made the helicopter the most efficient way to carry out the assembly in just a few hours. Thats why it was necessary to design the wood panels and the dimensions of them considering the maximum load of the helicopter: 800kg.

The design of the cabin starts from an absolute respect for the environment in which it is placed. The foundations of the building were performed using metal gabions filled with rocks instead. This idea allows that if in a few years the building it’s remove from there the only necessary process consists to empty the stone gabions and remove the structure, that way we can  leave the place without any trace of foundation and waste.

The building is oriented to the south through a large window double glazed with low emissivity which will serve to improve the passive solar gain in summer and energy efficiency. With that idea in mind, the energy efficiency, we have built walls and wooden floors filled 20 cm and 25 cm respectively with cotton, creating a recycling mantle intended to minimize heat losses. The electricity needed is produced by photovoltaic panels on placed on the roof while a wood stove helps to heat the cabin during the coldest nights. To be able to resist the  strong winds blowing from north at 2200 m of height, we designed a roof oriented to the north that reduces wind resistance and helps prevent the accumulation of snow in winter on the south facade.

Estanilles Refuge it’s a construction made by Acció Natura in collaboration with the Parc Natural de l’Alt Pirineu, the Generalitat de Catalunya and the Obra Social La Caixa. It was built by NOEM and designed by NOEM and Josep Bunyesc.



At NOEM we design and build custom homes from Barcelona, using wood as the basis of our projects and prefab technology as a manufacturing process. Our modular homes achieve maximum energy efficiency through passive house standards and the latest technology.

The Eco-house 3.0


Published in Barcelona 11.The Eco-house 3.0 is a bio-climatic and technological house, built in record time using a 100% digital process. It features a modern and cosy design with advanced technology that allows full automation from a smartphone and achieves maximum energy efficiency. What more could you ask for? The owners of this unique home wanted a digital building that would be respectful to the landscape they had fallen in love with. NOEM designed and built this modern passive house for them, and in ten weeks delivered it ready to move into.

The owners of this ecological house 3.0 are a couple who, after a long working life, began to prioritize time shared with friends and contact with nature. For years, they dreamed of a small shelter in the area of Serra Espadà (Castellón – Spain). One day, they made their decision; they would build their dream house using a prefab wood modular system to make the process quick and clean, and to maximize energy efficiency and comfort. One of the owners, a technology lover, was passionate about the idea of building a passive house through a 100% digital process so they could have a flexible construction he could transform over time if he needed to. Today he is the owner of the house that he dreamed of, his “refuge”.


This ecological wooden house 3.0 is a 100% digital construction: its design, its manufacturing process and also the control and the use of the house are 100% digital. Digitization has allowed us to design a made-to-measure bio-climatic and intelligent house, and, during manufacturing, to send all the designed pieces directly to digital cutting machines without human intermediation. The result is an efficient and sustainable home in every sense: “economic sustainability” as we save time and errors in production (8 weeks + 1.5 prefabrication assembly) and pursue a continuous process of optimization; and “environmental sustainability” through the intensive use of local renewable building materials and an efficient energy use.



All home systems are interconnected via Internet, even the switches. The switches need no wiring and operate via radio, so we can move them around the house or change their function in the system. Neither electricians nor cables are needed to do so. Home automation allows us to not only easily increase comfort, but also to act autonomously to achieve greater energy efficiency. The HVAC system is adapted to the weather forecast, the irrigation system operates according to soil moisture and rain forecast, and the mechanical ventilation can detect when the CO2 concentration is too high and renovates inside air. Lighting systems can be synchronized with scheduled events on the owner’s calendar, and can be programmed via GPS or detectors to wake him up or to greet him when he approaches home.




In order to ensure the energy efficiency of this ecological house 3.0, as a first step, the plot and the meteorological databases for this location have been rigorously analyzed. No room for intuition and good luck. The path of the sun in every season, the shadows cast by neighboring houses, the wind direction and speed, the average temperature, humidity, rainfall…hundreds of data has been analyzed to generate energy simulations of the future house’s behavior. Only with this deep initial analysis could we ensure that all our customer’s specific desires are achieved: “a house that consumes less than 15 kWh/m2 per year…the sunlight in winter reaching the couch in the afternoon…or producing all the energy the house consumes.” With correct Big Data Analysis we know if these desires can be accomplished and efficiency can be ensured.




The plot data combined with user needs and requests define a ground where the architect can play. The design and material proposals that fulfill these requirements are presented to the customer until we reach a fully satisfactory solution. With the construction goals clear, we can enter into the deep design phase.”The refuge” consists of two prefab wood modules manufactured in our warehouse and assembled on site, with a total floor area of 96m2. A broad and generous porch with a large automated awning faces south and overlooks the Serra, welcoming us.  The bigger module (9 × 4.5m) contains a living room/kitchen light that attaches to the porch with a retractable 3 meter wide accordion window, and it combines the two spaces into one.


A second 9x3m module contains a double bedroom, a bathroom, and a flexible study that is transformable into a double room. The modules are built with solid structural panels of 81mm laminated wood. Thick 16cm wood fiber panels thermally insulate the entire shell. Larch wood pieces are mounted on a ventilated facade, and high performing windows conform the outer skin we see. And from the inside, wooden beams, parquet floors, and white walls are combined.


Digitization has allowed us to share this design process entirely in real time with the client. The same 3D model used for the design and manufacturing process was also used to make virtual tours inside the house so the owners could experience the house from their iPad as if it was a video game. They could imagine “living” in their new home virtually before building it, and monitor the evolution of the project despite being 300 kilometers away from the NOEM offices. To design this prefabricated house, we generated a 3D BIM model of the architectural proposal. Every material and every little detail of the house was designed to the millimeter, and a mounting sequence was simulated as if the house was in an assembly line. Absolutely everything is included in the model: each screw, each joint, all the doors, windows’ details, and measurements; even the exact hinge model of every piece of furniture. No room for improvisation.The finished BIM model is ready as soon as it is tested and verified by team, approved by the customer, and the production order of all the elements is given. GO!




With the house designed to the millimeter, piece by piece, and with all embedded items, we proceed to the next phase of the digital process of building this ecological house: prefabrication. The whole design is sent directly without intermediaries to CNC machines which use laser cutting to secure pinpoint accuracy. Every supplier receives complete files to manufacture the different parts, so there is little room for error. With digital tools linking the manufacturing process with the design, the architect becomes the builder and acquires full control of the process. This ensures a higher quality output and minimizes errors.   4. ASSEMBLY The prefabricated house arrived to the plot in two trucks, each one with a 3D module completed with all facilities, carpentry, kitchen, and bathroom waiting to be connected and for the finishing details to be made. After arriving at the plot, the house was ready in six days. The digital prefabrication process had also allowed an assembly simulation, and no difficulties were encountered aside from finding a home for the local bees.




The digital design of the house allows us to avoid conventional home automation and go for a self-managed intelligent control system. We install sensors and actuators through a home automation switchboard to be able to monitor and analyze all systems in real time and achieve superior levels of energy efficiency and comfort. Today, “the refuge” has an open center automation IP protocol that allows us to freely integrate new connected elements even if they are from different manufacturers as used IFTTT protocols. Temperature, humidity, energy consumption, sunlight, and air quality data are analyzed by the switchboard, which according to the settings can activate different systems automatically. When the sensors detect that the air contains a high value of C02, mechanical ventilation which introduces fresh air into the house is automatically activated. The switchboard automatically raises and lowers the blinds and extends or retracts the awning depending on the weather forecast to achieve the desired temperature within minimum power consumption guidelines. On a cold winter day, indicated by the GPS on a user’s mobile phone, the switchboard activates the heating system 20 minutes before their arrival to optimize energy consumption.Garden sensors detect the level of soil moisture and irrigation, and are activated only where and when necessary. Every morning, the first water drop from the shower is already hot, as the switchboard has activated a water recirculation pump to fill the pipes with the hot water of the solar deposits 5 minutes before the scheduled shower time. And the owner can access on his smartphone the current electricity production of the solar panels, the amount of hot water he has in the solar tanks, or the household electricity consumption.


In short, El Refugi is an ecological wood house designed and built tailor-made and with 3.0 digital technology in record time. All without forgetting comfort and design. It demonstrates its efficiency through facts: it’s energy consumption is class A with only 15.05 kwh / m2 (representing consumption savings of 90% compared to a traditional dwelling) and it has a negative CO2 footprint of 56.95 kgCO2 / m2, equivalent to the CO2 emission from a car driven 4,5 times around the circumference of the Earth.


Finally, El Refugi allows all data to be accessible in real time via smartphone for more efficient and comfortable use (consumption and energy production, water consumption, temperature, humidity, and more).Our customer’s dream.




At NOEM we design and build custom homes from Barcelona, using wood as the basis of our projects and prefab technology as a manufacturing process. Our modular homes achieve maximum energy efficiency through passive house standards and the latest technology.
