Assessment and support for
Legalisation
We assess the existing situation, identify the applicable framework and support the process with the relevant authorities.
We coordinate architecture, construction and specialist services.
Common situations
Requiring legalisation.
- Unapproved extensions
- Built areas not included in the approved design.
- Changes to facades and openings
- Alterations carried out without the required authorisation.
- Change of use
- Properties used for a different purpose.
- Outbuildings
- Structures built without authorisation.
- Differences between the design and the building
- Where the existing building does not match the design.
What we assess
We assess the property and the applicable framework.
- Planning framework
- We check the rules that apply to the property.
- Existing documentation
- We review drawings, permits and other documents.
- Current state of the property
- We compare the existing building with official documentation.
- Constraints
- We identify constraints that may limit the proposed work.
- Feasibility of legalisation
- We identify constraints that may affect regularisation.
Every case starts with an assessment
Not every situation can be handled in the same way. Before proceeding, it is essential to understand what exists, what has been approved and which rules apply to the property. In some cases, it may not be possible to legalise the proposed situation at all.
Legalisation through an organised process.
We assess the existing situation, identify the applicable framework and support every stage through to regularisation.
Assessment
We gather the available information and assess the property, the existing file and the applicable planning framework to understand what needs to be regularised.
Survey
We inspect what is on site and compare it with approved or registered documents, identifying alterations, discrepancies and missing information.
Preparation
We develop and organise the required technical documents, adapting the solution to the applicable rules and procedural requirements.
Support
We submit the application and follow it up with the relevant authorities, responding to requests for clarification and supporting the necessary steps through to completion.
What is needed for an initial assessment?
Coordinated architecture, construction and specialist technical services.
Property identification
Address and basic information about the property.
Existing documentation
Plans, designs, permits, certificates or other documents.
Current situation
Information about the situation you wish to regularise.
Additional information
Photographs, correspondence from the local authority or other material that may help explain the case.
Don't have all the documents?
We can start by reviewing the available information and help with what is needed from there.
FAQ
How do I know whether my property needs legalisation?
If there are structures, extensions or alterations that are not included in the plans approved by the local authority, regularisation may be needed. The assessment starts by comparing the existing property with the available documentation.
Can any building be legalised?
Not all buildings can be legalised. Feasibility depends on the property's characteristics and the applicable planning rules. In some cases, adaptation works may be needed before the process can be completed.
Which documents should I gather for an initial assessment?
Where available, gather the property tax record, land registry certificate, approved plans and municipal documents relating to construction and use. The location, current photographs and a description of alterations will help the assessment. If you do not have all the documents, contact us so we can identify what is missing.
How long does legalisation take?
The timescale varies according to the complexity of the case, the available documentation and the procedures with the relevant authorities. After the initial assessment, we can identify the expected stages and factors that may affect the duration.
How much does property legalisation cost?
The cost depends on the surveys, designs and specialist disciplines required, municipal fees and any adaptation works. TNV prepares its proposal after assessing the case, identifying the included services and expected external costs.
