Transforming the existing,
building the future
Renovation represents a major architectural, energy and regulatory challenge. Whether it involves apartment renovation, villa transformation or residential building refurbishment, each project requires a precise understanding of the existing building and the Geneva regulatory framework.
Our architectural office in Geneva develops renovation and transformation projects, integrating from the earliest stages the constraints linked to construction permits, LDTR regulations and energy requirements.
We support renovation projects in Geneva, across all existing buildings
Energy renovation
Energy renovation improves the performance of existing buildings while reducing energy consumption and operating costs. We develop energy renovation projects in Geneva integrating thermal insulation, replacement of technical systems, façade improvements and optimisation of building performance, in coordination with cantonal requirements and subsidy applications.
Heritage renovation
Working on heritage buildings requires a precise and sensitive approach. We develop heritage renovation projects in Geneva that balance preservation of architectural character, technical upgrades and adaptation to contemporary uses, while respecting regulations linked to protected buildings.
Villa renovation
Villa renovation allows existing spaces to be transformed while improving comfort and quality of life. We develop villa renovation projects in Geneva ranging from interior reorganisation to extensions and energy improvements, with particular attention to architecture, light and materials.
Rooftop extension
Vertical extensions represent an opportunity to densify and enhance existing buildings in Geneva. We develop extension projects integrating structural, regulatory and energy constraints in order to create new spaces coherent with the architecture of the existing building.
Apartment renovation
We develop apartment renovation projects in Geneva ranging from complete transformations to the reorganisation of interior spaces. Each project is designed according to use, natural light and technical constraints, with the aim of improving comfort and spatial quality.
Commercial fit-out
Commercial fit-outs require an approach that is both functional, regulatory and architectural. We design spaces adapted to the activity, brand identity and operational constraints, developing projects that are coherent, durable and optimised for daily use.
We place our clients at the center of every project
We place our clients and their vision at the heart of every project. Our mission is to provide personalised guidance throughout the entire architectural process, from property search and early feasibility to renovation and final handover. Careful listening and close collaboration allow us to transform ideas into coherent, well-resolved projects.
Our vision is to create spaces that are functional, aesthetic and durable.
Renovation and transformation are approached with respect for what already exists, revealing potential rather than imposing form. Decisions are guided by architectural quality, material sensitivity and a deep awareness of context.
We bring our expertise to renovation projects
Understanding the existing
Every renovation project begins with a detailed analysis of the existing building: structure, condition, spatial qualities and technical constraints. This assessment helps identify transformation potential and guide the first design decisions.
A careful transformation
We develop architectural renovation projects through coherent interventions adapted to both context and use. The aim is to improve spaces while enhancing the value of the existing building.
A sustainable approach
Energy renovation is integrated from the design phase, with careful attention to insulation, materials and technical systems in order to meet current energy performance standards in Geneva.
Energy renovation and subsidies
Energy renovation in Geneva is strongly encouraged through financial support provided by the canton and certain municipalities.Subsidies may be available for projects involving thermal insulation, replacement of technical systems and overall improvements to building energy performance.
These programmes, particularly those linked to the Geneva cantonal energy programme, require early coordination with the architectural project.
We assist with the integration of subsidy applications into renovation projects in order to optimise investments and ensure compliance with energy requirements.
Une rénovation maîtrisée
All renovation projects in Geneva are subject to a specific regulatory framework. Depending on the scope of the works, a simplified construction permit (APA) or a full application (DD) may be required.
Residential renovation projects are also regulated by the LDTR (Geneva law governing demolitions, transformations and renovations), which aims to protect the existing housing stock.We manage the preparation of construction permit applications in Geneva, including drawings, technical documentation and coordination with the authorities, ensuring a clear and compliant approval process
Diagnosis and CECB+
We provide early advice before the purchase of a property. This can include accompanying you during visits, assessing the existing condition, planning constraints and development potential, helping you make informed decisions before committing.
Project design
We analyse what can realistically be achieved. This includes reviewing regulations, buildable volumes and the existing structure. Different options are explored to define a clear and viable direction for the project.
Construction permit
We develop the architectural concept through plans and spatial organisation. Light, circulation and material strategies are defined to create a coherent proposal aligned with your needs and the project constraints. At this stage, we also establish a preliminary cost estimate and define a project timeline, ensuring that the design remains realistic and well-structured.
Construction management
We develop the project in detail and prepare all drawings and documents required for submission. The design is coordinated with regulations and technical requirements to ensure a clear and compliant approval process.
Subsidy applications
We follow the project on site and coordinate the different contractors. Execution, materials and details are monitored to ensure that the project is built as intended. We also oversee the project timeline and budget during this phase, ensuring that construction remains aligned with the client’s objectives through to completion.
FAQs
What renovation works require a construction permit in Geneva?
In Geneva, many renovation works require a construction permit, particularly when they involve structural changes, façades, window modifications, changes of use or major energy interventions. Depending on the project, this may involve an APA (simplified permit procedure) or a DD (full application procedure).
What is the difference between an APA and a DD in Geneva?
An APA (simplified construction permit) generally applies to smaller-scale works, while a DD (full application) concerns more complex projects or those subject to stricter regulations. The procedure depends on the nature and scope of the works.
How much does a renovation project cost in Geneva?
The cost of a renovation project in Geneva depends on the type of project, the condition of the existing building, technical constraints and the desired level of finish. A cost estimate is established from the early phases of the project in order to define a realistic and coherent budget.
Are there subsidies for energy renovation projects in Geneva?
Yes, the canton of Geneva offers various subsidies for energy renovation projects, particularly for thermal insulation, replacement of technical systems and improvements to building energy performance. These subsidies generally need to be integrated from the design phase of the project.
How long does a renovation project take in Geneva?
The duration of a renovation project depends on its complexity, administrative procedures and the type of permit required. A renovation project generally includes several stages: feasibility studies, design, construction permit approval and construction works.
Why work with an architect for a renovation project?
An architect coordinates the project as a whole: analysis of the existing building, architectural design, construction permits, budget management and site supervision. This approach ensures a coherent vision of the project and better control of technical and regulatory constraints.
When should an architect be consulted for a renovation project?
It is recommended to consult an architect from the earliest reflections on the project, or even before purchasing a property. This allows the building’s potential, regulatory constraints and transformation possibilities to be assessed before making any commitment.
