House in Maresme

Read description

Maresme · Sur: 358 m2

The project of this two-storey single-family home is designed to meet three main goals:

Firstly, the home must be an energy-independent entity, even exceeding the standards of NZEB (Net-Zero Energy Building).

To achieve this, the building has high levels of thermal insulation outside, as well as high-efficiency glazing with solar control and an air renewal system with a heat exchanger.

The installations are highly energy-efficient and are connected to a set of photovoltaic panels that provide electricity to the whole house. In addition, this system is also able to accumulate the excess energy that is not being used, allowing the charging of electric vehicles or the subsequent reuse of energy in the home itself.

On the other hand, due to the great transparency and permeability of the garden facade, the daytime areas are closely connected to the outdoors and boast great panoramic views. The volumetry of the house itself separates this space from the street, offering good privacy.

Finally, in the future, the two floors could actually work separately with an independent layout on each floor. This has been made possible by incorporating a large multipurpose room in the bedrooms area on the first floor, which could function as a daytime area.

House in Sant Just Desvern

Sant Just Desvern · Sur: 322,00 m2

A semi-detached three-story house between party walls whose south façade opens up onto a large courtyard in a staggered manner.

The ground floor comprises the daytime areas which boast great transparency towards the outside, and the permeability between the living room and the kitchen can be regulated by means of a long glass sliding door.

An exposed concrete staircase located in the middle of the floor connects with the nighttime areas on the first floor, which has a terrace facing south for the suite and study.

The exposed concrete slab of the below deck serves as an open play area for the children and has an access to a south-facing terrace.

Both the exterior and the interior of the house combine soft grays and natural wood with white and black.

The construction project follows criteria of energy efficiency, both in its passive and active systems, and will also have a solar collecting system that will generate electricity for self-consumption in the house.

Semi-detached houses in Sant Cugat del Vallès

Read description

Sant Cugat del Vallès · Sur: 429 m2

The project consists of two semi-detached houses, asymmetrical in dimension and layout but sharing the same morphological and energy criteria.

The two houses make up a large white rectangular volume which gets disrupted on the ground floor and generates small discontinuities on the facades that reunite again in the four corners of the rectangle.

Daytime areas are located on the ground floor of both houses, with open spaces made up of kitchen isles which open to their respective sitting rooms with large openings to the outside.

One of the building’s main features is its high degree of continuous thermal insulation which substantially increases the houses energy efficiency and environmental sustainability.

The whole structure rests on a large gray stone base which contains the car parks in its interior and forms the garden and the terraces at the top.

House in Priorat

Tarragona · Sur: 294 m2

The Project came from the merging of two plots with existing buildings that bore no historical interest and were knocked down. The new build aimed to create an interior patio, and a main façade with natural stone and vertical openings in keeping with the street’s historical environment. The inside façade has large windows to get the maximum amount of natural light in.

Efficient Eco Housing in the Empordà

Read description

Bellcaire de l’Empordà, Girona · Sur: 17.294 m2

A set of houses that adapts to the topography of the land and the street. The urbanization, with the Montgrí in the South and the Pyrenees in the North, is formed by houses asymmetrically attached.

The dwellings are formed essentially by two cradles in ground floor: with the kitchen and a room in one of them and the other with the living-dining room. The latter is a diaphanous space with a North-South longitudinal transparency. In the first floor a longitudinal volume accommodates the bedrooms and a large multipurpose space in the area of the staircase with transparency towards the terrace of the upper level.

The project is designed with sustainable construction and energy efficiency criteria:


  • Use of natural materials with low environmental footprint from the nearby environment and in accordance with those traditionally used in the area such as natural stone and lime mortar.
  • Enclosure with high thermal insulation and without thermal bridges to contribute to minimize the use of active means of climatic conditioning.
  • Breathable thermal insulation materials and insulation that prevent moisture and condensation in the interior.
  • Passive and dynamic solar protection of all openings.
  • High energy efficiency thermal installations combined with solar panels.
  • Lighting of high energy performance and low consumption.
  • Active system for the renovation and control of indoor air quality.
  • Active radiation protection of electrical elements and circuits.
  • Advanced domotic system and digitalized of the mechanically active elements of the house.
  • Rainwater collection system for later re-use in the garden.

House in Barcelona

Read description

Barcelona · Sur: 251 m2

In an old house in the center of the Horta district, the project recovers the back yard and increases the specifications by extending the house with another level. In addition to the general redistribution of spaces and structural consolidation, the aim is to build a house with almost no energy consumption by using passive elements and high energy-efficiency systems.

Bar the systems, all the construction methods used could be considered “conventional”, which shows that you can design a highly energy-efficient building with any construction system if the passive systems are properly analyzed and adequately combined with technology.

Inside, original features are restored and left exposed, such as old wooden beams and brick walls, all combined with new materials in shades of white, light gray and natural wood.

Torrelles de Llobregat, Barcelona · Sur: 252 m2

The house was built in a very difficult terrain, very sloped, and in a very chaotic environment, a residential area made up of isolated single-family houses with very different aesthetic and urban criteria.

The Project uses the incline of the terrain to create an Access from above and places it so that it has views to the building-free mountains, forming a volume that frames these views.

House in Parets

Barberà del Vallès, Barcelona · Sur: 215 m2

In a long and narrow plot, the house is located at the back, in two levels, leaving a lot of outdoor space, and reorganizing the scale of all the elements. Various options are considered: a very cubical house based on the concept of White monolith with bites that leave the inside wood visible. A second option, on the ground floor in which the house is made up from two very clear volumes, and a third design in which the house is made through planes.

High energy-efficiency houses in Reus

Read description

Reus, Tarragona · Sur: 113.689 m2

Blocks of flats organized as strips that emulate the tapestry-looking fields of agricultural farming. The blocks have big crossings in the form of bridges that allow transversal permeability of streets and pedestrians. The designed buildings are highly energy-efficient and have negative consumption, that is, they generate more energy than they use through solar and wind-capturing systems incorporated on both the façades and the roofs. The leftover energy can be used in other areas. They also use ecological and recycled materials. The whole building has shared elements such as terraces and accessible roofs for urban gardens.

Residential building in Sant Hilari

Read description

Sant Hilari Sacalm, Girona · Sur: 2.361 m2

A 20-flat block with underground car park and a very tight budget. The project outlines a central spine with services, which frees up the perimeter and the façade for rooms, all tightly organized. The climate in the area, with frequent snow, clearly defines the volumetry of the building, which has a very sloped roof. The building system, semi-prefab and lightweight concrete in the neutral areas, meant that the process was sped up and carried out in record time, minimizing the potential costs for excess of weight and materials.
