Building renovation and refurbishment in Valencia
Before intervening in an existing building, we analyse its real condition, urban planning constraints and possible technical limitations. This preliminary study allows us to identify hidden issues, assess the feasibility of the operation and define a safer, more efficient and more profitable renovation strategy.
Renovation projects often require particularly careful interventions in order to adapt existing buildings to current regulatory requirements, especially in terms of fire safety, accessibility, habitability and energy efficiency. At JSJ Arquitectos, we have extensive experience in this type of project, incorporating thermal and energy improvements that are compatible with the construction reality of each building and with the urban planning and regulatory conditions of Valencia.
Renovation services
We develop renovation projects from the initial technical analysis and due diligence through to project drafting, licence processing and site supervision. As in residential development projects, we support the developer throughout every stage, even before the acquisition of the asset, providing technical knowledge and experience in the local market.
PRELIMINARY ANALYSIS AND DUE DILIGENCE
Before acquiring or intervening in a property, we analyse its real condition, structure, envelope, installations, easements, heritage protection and urban planning feasibility. This work allows us to identify pathologies, hidden costs and constraints that may affect the profitability of the operation.
LICENCE, REGULATIONS AND ADMINISTRATIVE PROCEDURES
We prepare the documentation required for licence processing, incorporating compliance with the applicable regulations on safety, accessibility, habitability, energy efficiency and installations. Our knowledge of the local context allows us to anticipate administrative and technical constraints.
CHANGE OF USE IN EXISTING BUILDINGS
We study change-of-use operations in existing buildings, assessing urban planning compatibility, evacuation, accessibility, layout, installations and the adaptation of the property to the new functional programme. This analysis is especially important for assets intended for residential, hotel, tourist accommodation or tertiary use.
RENOVATION OF PROTECTED BUILDINGS AND HERITAGE ASSETS
We have experience in the renovation of protected buildings and in interventions located within protected heritage settings, where the project must coordinate heritage, urban planning and technical criteria from the earliest stages. This experience allows us to anticipate specific constraints, define viable intervention strategies and make the recovery of the building compatible with its adaptation to new uses.
SITE SUPERVISION AND EXECUTION
We support the project through to its execution, coordinating construction solutions, technical criteria and on-site decisions to ensure that the renovation is carried out in accordance with the project, the licence and the developer’s goals.
Our experience
Our experience in building renovation combines residential interventions, protected buildings and change-of-use projects to hotel-apartment in Valencia, including projects in consolidated urban areas such as Ciutat Vella. We have worked on buildings with complex heritage, regulatory and technical constraints, where the feasibility of the project depends on coordinating architecture, structure, installations, licensing and use strategy from the outset.

Are you considering renovating
a building in Valencia?
At JSJ Arquitectos, we approach building renovation from the preliminary analysis and due diligence through to the development and architectural execution of the project. We assess the real condition of the property and its technical, urban planning and regulatory constraints in order to define a viable, safe intervention adapted to the objectives of the operation.
