Beter Benutten Bestaande (Better Use Existing)

The resource titled "Beter Benutten Bestaande (Better Use Existing)" is published by the Platform Woonopgave in collaboration with the International New Town Institute. It explores opportunities for sharing, splitting, and small-scale infill housing in neighborhoods with row houses built in the 1960s, 70s, and 80s, commissioned by the Ministry of Housing and Spatial Planning.

The report addresses the ongoing housing crisis, emphasizing a shortage of over 400,000 homes in the Netherlands, particularly affecting young people. The disparity between those who can afford housing and those who cannot has widened. The average price of a home has increased significantly, making it challenging for many to enter the housing market.

The study highlights the potential of utilizing existing houses more effectively. By dividing larger family homes, particularly those occupied by older residents whose children have moved out, there is an opportunity to create additional living spaces for smaller households. This approach could accommodate an estimated three million additional people within existing housing stock without the need for new construction.

A significant finding indicates that 42% of the current housing stock consists of row houses, with many built in the post-war period. The study identifies 2,460 neighborhoods with at least 300 row houses, representing approximately 1.67 million homes. The average household size has decreased from 3.2 persons in 1970 to 2.1 persons today, suggesting that many households are currently living in homes that are larger than necessary.

Despite the potential for increasing housing availability through splitting and sharing, there are barriers including complex regulations and high costs associated with renovation and permits. Only about 5% of the potential for splitting existing homes is currently being utilized, due to these challenges.

The report also outlines how this approach can contribute to sustainability. By creating smaller, more suitable living spaces, it can enhance social cohesion, reduce loneliness among the elderly, and potentially lower healthcare costs. Furthermore, integrating green spaces and community facilities can improve neighborhood livability.

Several financing models are proposed to facilitate these changes. One model involves a shared mortgage option that allows multiple parties to co-own a property, thereby increasing affordability. A municipal model suggests that local governments could finance renovations to ensure homes remain affordable for future buyers.

In conclusion, the report underscores the importance of rethinking existing housing strategies to address the housing crisis sustainably. Through sharing and splitting existing homes, along with small-scale infill, it is possible to create more affordable living options while enhancing community ties and supporting environmental goals. This approach not only addresses immediate housing shortages but also aligns with broader sustainability efforts in urban planning.
