The economic usability of a property does not end only when technical defects arise. A building can remain technically functional while losing demand.
Occupier requirements change with the market. Floor plans, space efficiency, building technology, energy consumption or specification standards influence the competitiveness of a property.
Obsolescence describes the loss of functional or economic suitability. The technical condition may initially remain unaffected.
The adaptability of a building influences how long it can accommodate changing requirements. Flexible floor plans facilitate new use concepts. Good divisibility broadens the potential occupier pool.
Building technology is subject to the same process. A technically functional system may become economically outdated if operating costs or performance no longer meet prevailing market standards.
The year of construction provides only an indication. An older building can remain aligned with the market after modernization or conversion. A younger building may become economically obsolete earlier if its structure restricts change.
The marketability of a property therefore does not depend solely on its technical condition. The market compares a property with available alternatives. Functional disadvantages are often reflected in longer marketing periods, lower rents or higher capital expenditure requirements.
The valuation must take such developments into account where they affect value. The impact may relate to sustainable income, third-party usability or remaining economic useful life.
The remaining useful life is based on the period of continued economic usability. Obsolescence can shorten this period even though the technical life of the building has not been exhausted.
Modernization preserves marketability only where it removes an actual disadvantage. New technology alone does not improve the economic position of a property.
A change of use can create additional options. The new use must be technically feasible, legally permissible, and economically viable.
The assessment remains property-specific. The location shapes demand. The building structure limits or expands the scope for adaptation.
Technical functionality therefore represents only one part of the assessment. The property must also retain its economic usability under changing market conditions.
Technically intact does not mean market-aligned. A lack of adaptability reduces marketability.
Obsolescence is therefore one of the factors to be considered when assessing the sustainable marketability of a property.
