Are you among the 15% of foreigners who have bought in Spain, are you planning to do renovation work and you feel overwhelmed by a sense of panic at the idea of not understanding anything? Take a breath, the experts at Terreta Spain have prepared THE essential glossary of real estate renovation in Spain for you. It is not exhaustive and does not go into overly technical aspects, the goal here is to allow you to communicate simply with your workers if they do not speak French, to avoid misunderstandings and misinterpretations.
Let's go.
A
ACABADOS
The finishes, that is to say the last works carried out on a construction site. They include all the elements that give the final appearance to a building or a room (paints, coatings, tiles, decorative details, etc.). In Spain as elsewhere, the choice of finishes greatly influences the budget of the works.
ADHESIVOS
All substances used to glue or bind two surfaces together. The choice of appropriate adhesives depends on the type of material, the intended use (interior/exterior) but also the climatic conditions.
AISLAMIENTO ACÚSTICO
This refers to acoustic insulation, which aims to improve sound comfort inside buildings, whether residential or not. Particular attention should be paid to this insulation if you are investing in a densely populated area or in the city center, near restaurants, bars, and lively places. Spaniards have a reputation for being a bit noisy. Our team won't deny it... But it's this zest for life that we love.
AISLAMIENTO TÉRMICO
Thermal insulation. It is essential in carrying out the work. The goal is to prevent heat transfer between the interior and exterior. There are several insulation techniques, and choosing the right one can reduce the need for heating and air conditioning. In a country like Spain, this is essential to reduce the energy consumption of homes. To delve deeper into this topic, check out our article: "Energy renovation in Spain, the complete guide".
ALBAÑIL
A bricklayer, a construction worker.
ALCANTARILLADO
The sewage system. Your future home must be well connected to the urban network to properly dispose of wastewater.
APAREJADOR
The site manager or technical architect (arquitecto técnico). This is a key professional in the construction sector. Their main responsibilities are:
- The technical direction of the execution of the works

- The control of costs and deadlines
- Guaranteeing compliance with safety standards and regulations
ARQUITECTO
A qualified and accredited architect, responsible for the design and planning of buildings and spaces. They are in charge of:
- The design of plans and technical drawings
- The creation of the overall aesthetic of the building

- He supervises the project in its entirety
- He coordinates with other professionals involved in the project.
Not to be confused with the construction manager (the aparejador) who has a more technical profile.

It also serves as the basis for calculating certain taxes such as IBI (Impuesto sobre Bienes Inmuebles, equivalent to property tax). Note that the land registry information is publicly accessible, making it an important tool for real estate transactions and urban planning.
CÉDULA DE HABITABILIDAD
This is an administrative document certifying that a dwelling meets the minimum habitability and safety standards required by law. It specifies the living area, the number of rooms, and confirms that the dwelling has basic facilities (water, electricity, sanitation). Its validity period varies by region, generally extending from 10 to 15 years. Without this certificate, it is legally impossible to inhabit or rent the dwelling. To obtain it, the dwelling must be inspected by an approved technician. Upon expiration, the certificate must be renewed, which may require upgrades to the dwelling to meet current standards.
CERTIFICACIÓN DE OBRA
This is a document validated by a technician that describes the quantity and quality of work completed to date on a construction or renovation site. It allows for the official tracking of work progress and is often used as a basis for staggered payments to contractors or builders.
