Adding storeys and extensions made easy
In Zurich, the consultation on the revision of the Planning and Building Act has begun. The aim is to make it easier to convert and extend existing buildings and to promote the maximum utilization of land. The aim is to make better use of ecological, social and cultural benefits in future.
The further development of existing buildings offers clear advantages. It saves resources, reduces CO2 emissions and reduces the volume of construction waste. In contrast to demolition, the appearance of the neighborhood is preserved and new rentals are often lower, which ensures affordable living space. The local building culture also benefits, as established structures and identity-forming elements are preserved, which strengthens the sense of community.
High hurdles hamper conversions
Outdated regulations, complex procedures and a lack of legal certainty are currently hampering numerous extension projects. Older buildings in particular do not comply with the latest regulations, so many owners shy away from the effort involved and prefer to build new ones.
Revision of the law brings simplifications
The new proposal from the Building Department provides for targeted simplifications. At its heart is the simplification provision, Section 220a E-PBG: it allows owners to deviate from certain regulations, for example with regard to boundary distances, façade height and the number of full storeys. The aim is to better integrate the further developed building into the existing building regulations, create more scope for conversion and at the same time offer legal certainty.
Densification and better utilization
It will be easier to create additional residential units, particularly in residential buildings. The regulation encourages properties to exploit their full potential in accordance with the municipal zoning regulations without losing the existing building stock. This is an important step towards more densification and smart land use in urban and rural areas.
Further simplifications and updates
The revision also addresses the demands of the Cantonal Council. For example, procedures for solar installations and stair lifts have been simplified. Outdated regulations on fire protection and minimum heights are to be removed. This will make it easier to convert office buildings into apartments and provide impetus for innovative construction projects.
Opportunity for Zurich
The planned simplifications for the conversion and extension of existing buildings will enable sustainable urban development, ecologically, socially and culturally. The revision of the law creates clarity and motivates owners to use the potential of existing buildings instead of building new ones.
