Planning, costs and challenges when converting an old building
An apartment in an older building often possesses a special charm: high ceilings, generous windows, historical details, and a unique atmosphere. At the same time, many older apartments no longer meet today's requirements for comfort, spatial layout, or technology. Anyone wishing to renovate an older apartment therefore faces an exciting challenge: preserving the character of the existing apartment while simultaneously creating modern living comfort.
Especially in cities like Basel, where many apartments date from different construction periods, renovating an older apartment is a frequent challenge. With careful planning, the potential of these apartments can be optimally utilized – both for personal living comfort and for the long-term value of the property.
Why professional interior design is particularly important in old buildings:
Apartments in older buildings differ significantly from those in new buildings. Often, building plans are incomplete, or the existing building structure has peculiarities that must be taken into account during the planning phase .
An interior designer therefore first analyzes the existing conditions of the apartment:
Spatial structure and floor plan
existing installations
load-bearing walls
historical building elements
Lighting conditions and room proportions
The aim is to preserve the character of the apartment while simultaneously developing a functional room structure for today's everyday life.
Especially in older buildings, it becomes clear that interior design goes far beyond mere aesthetics. It combines planning, technology, and design into a holistic concept.

Typical challenges when renovating an old apartment
Floor plan and room layout
Many older apartments were planned at a time when different housing needs were paramount. Small kitchens, separate living areas, or long hallways are typical examples.
Targeted optimization of the floor plan often allows rooms to be used much more effectively.
Technical installations
In older apartments, installations often need to be renewed or adapted, for example:
Electrical installations
Sanitary pipes
Ventilation systems
These adjustments must be carefully planned to avoid problems later on.
Preservation of historical elements
Older apartments often possess valuable details such as stucco ceilings, parquet floors, or historic doors. When renovating, the question often arises as to which elements should be preserved and how they can be integrated into a new spatial concept.

Planning an old building renovation – step by step
A successful renovation always begins with structured planning.
Analysis of the existing apartment
Initially, the existing spatial structure and the building's structural conditions are examined in detail. This also includes assessing which elements can be preserved.
Development of a spatial concept
A new spatial concept is developed based on this analysis. Typical goals include:
better use of living space
Integration of modern living needs
harmonious combination of old building and modern materials
Planning of materials and interior design
The next step involves defining materials and surfaces. Especially in older apartments, the combination of historical and modern materials plays an important role.
Preparation for implementation
The planning is then translated into detailed execution plans. These form the basis for implementation by tradespeople and specialist planners.
