Home Building and Rehabilitation Abeiro


Construction is the core of Abeiro’s business and it is what has allowed us to diversify our current lines of business as a construction company in Galicia. Always under the highest quality standards, we provide solutions to facades, roofs, reforms and newly constructed line. We have a team of carpenters, stonemasons and technicians with a high level of experience and dedication, prepared to undertake any type of project effectively. 

Reforms: we feel comfortable in the reform works of houses and flats in Santiago de Compostela and Galicia, commercial premises, offices or communities of neighbours. We design personalized projects according to the type of property and use that will be given to it.

Newly constructed line: Abeiro helps you design and build your single-family home. During the execution process of your home, we speed up the building process and deliver it on time. 

With the entry into force of the Royal Decree of the ITE (Technical Inspection of Buildings), the property is obliged to hire a technician to certify the soundness of the building before the Public Administration if it is more than 40 years old. It is therefore important to check the state of the facades, roofs and installations.

Abeiro, as a construction company in Santiago de Compostela, has extensive experience in carrying out maintenance and conservation work on structural elements of buildings. For this reason, it guarantees:

  • Durability and safety of the building.
  • Reduction of energy consumption.
  • Avoids the devaluation of the building.
  • Prevents that the defects of maintenance and conservation generate more expensive rehabilitations.
  • Improves well-being.

Facade repairs: with the passage of time human and atmospheric aggressions deteriorate buildings, generating risks of detachment on public roads and worsening habitability conditions. Without preventive measures, the injuries produced on facades can turn into serious pathologies, risks and unnecessary costs. 

Roofs: they are one of the most punishing elements of the building as they are continuously exposed to the weather conditions, and therefore, one of the elements that requires the most maintenance. Waterproofing is essential to maintain the good condition of buildings, ensuring the watertightness and protection of the building. 

Installations: the good condition of a building’s installations is basic for its good conservation. The construction company Abeiro carries out repair work on faecal and/or rainwater pipes, changes to downpipes, protection of smoke evacuation systems, as well as updating gas, electricity and water installations.


Abeiro is a specialist in the rehabilitation of homes and buildings in Galicia. Our interest in this activity stems from our conviction about the importance of preserving our heritage. Our activity as a construction company in Santiago de Compostela is focused on the conservation and recovery of historic buildings and properties, as well as unique locations in disuse and with a high cultural interest.

The recovery of buildings is today one of the most important areas of construction as it contributes to generating a lower climate impact compared to the construction of new buildings. The advances made in the construction sector in terms of new techniques, materials to be used and the development and specialisation of professionals dedicated to this area have contributed to the rehabilitation being one of the main activities within the sector.

The construction company Abeiro provides the most advanced and appropriate construction solutions for each type of rehabilitation, while promoting the conservation of traditional trades such as forging, stoneworking or carpentry. Aware of the need to transform existing buildings into energy-efficient constructions, Abeiro is committed to a rehabilitation that focuses on reducing energy demand in order to achieve more sustainable buildings. 

A very high percentage of the existing real estate in our country consumes energy inefficiently, making it necessary to use thermal insulation. One of the global objectives within the European Union is the progressive reduction of energy consumption from polluting sources to guarantee a more sustainable future for all. 

Abeiro believes that the rehabilitation of homes and buildings is necessary to improve the safety and health of a building, and an unbeatable opportunity for a comprehensive intervention including energy efficiency criteria.

Rehabilitation of listed buildings: the rehabilitation of listed private properties belonging to the historical heritage contributes to preserving the building quality and the aesthetic and historical value of the heritage, dignifying the properties and the city. 

These buildings have a large number of unique elements that must be treated with great care to repair their deterioration and restore their original state with traditional techniques and materials compatible with their architectural essence. 

The initial work of restoration starts with a detailed study of the property both from the constructive and historical point of view to know its evolution in time. This information is fundamental to carry out a responsible intervention.


According to the European guideline 2010/31/EU, the construction of nearly zero energy buildings, also called NZEB (Near Zero Energy Building), will be mandatory from the year 2020. This guideline responds to the need to build in a sustainable manner in order to generate a lower impact on the environment. Building is evolving towards a lower use of energy resources and towards sustainability. 

In order to measure the characteristics with which these buildings are being built, there are a series of certificates that serve to accredit these construction characteristics, such as Breeam, Leed, Well or Passivhaus. 

What is the Passivhaus standard?

The Passivhaus standard consists of reducing to the maximum the energy consumption of a house using the principles of the bioclimatic architecture, and obtaining through renewable energies when it is possible the little necessary energy to heat and to cool a house, although in case of maximum optimization a house with a null energy demand could be constructed. 

The passive construction or Passivhaus is based on some design criteria that allow the use of the energy and the natural light during the winter and the minimization of the solar incidence during the summer. 

Which are the basic principles of the passive construction or Passivhaus?

Thermal insulation: floors, walls and roof, the housing envelope, must be properly insulated to avoid energy loss in winter and energy gain in summer. At Abeiro we know that the quality of the insulation to be used is very important to achieve a correct insulation of the house.

Airtightness: the joints of the house must be perfectly executed to avoid air leaks both inside and outside the house, thus favouring the absence of energy loss or gain.

Windows and doors: these are the critical points of the house’s envelope and it is therefore necessary to select the materials with which they are built and take care of the execution of their installation at the same time to ensure that they have a high thermal performance.

Thermal bridges: great attention must be paid to the joints and structural elements to ensure the continuity of the thermal envelope and thus eliminate thermal bridges, which harm the energy efficiency of the building elements and increase the risk of condensation.

Ventilation: it is key to provide the house with a double-flow ventilation system with heat recovery to ensure proper ventilation and improve energy efficiency and indoor air quality. The heat recovery system exchanges the clean air that enters from the outside with the air that is extracted from the inside, recovering 95% of the heat expelled. The air that enters the house does so at a temperature very similar to the indoor temperature.

What are the benefits of passive construction or Passivhaus?

Passive construction provides the following benefits:

Economic: Passive house construction generates a lower energy demand and therefore a clear economic saving. This type of housing will tend to maintain a higher market value than others that are not sustainable or efficient in energy use.

Environmental: the lower use of energy resources has a direct impact on the environment since fewer polluting gases are emitted into the atmosphere.

Health: the quality of the air breathed inside a home is improved, as well as creating much greater thermal and acoustic comfort than in a traditional home.

Passivhaus was developed in Germany at the end of the 80’s, the first passive house was built in 1990 and finally the Passivhaus Institute was created in 1996.

The Abeiro team has the necessary preparation and certification to build passive houses or Passivhaus and low energy houses with a unique and personalized design in Galicia. We use the appropriate construction methods and materials to guarantee the insulation, electricity savings, almost zero consumption of heating, natural lighting and air circulation necessary to meet the standards of this type of construction. 

Build better, live better.
