As our population continues to rise, the debate on the best methods for accommodating growth intensifies. One significant consideration is whether to build taller buildings on already developed land or to expand into open land with new housing. Here are several compelling reasons why the former option is preferable.
Environmental Impact
Preservation of Natural Habitats:
Open land often serves as critical habitat for wildlife. Building houses on this land disrupts ecosystems, leading to loss of biodiversity. In contrast, developing vertically on previously used land minimises this ecological disruption.
Reduced Sprawl:
Taller buildings reduce the need for sprawl. Sprawl can lead to increased car dependency and higher greenhouse gas emissions. Concentrating development in existing main Centre and local centre areas promotes a more efficient public transportation system and reduces our carbon footprint as a community.
Economic Benefits
Efficient Land Use:
Building upwards makes the most of limited previously developed land. This is especially crucial in our densely populated island where building land is scarce and expensive. High-rise buildings can accommodate more people within the same footprint, maximising land use efficiency.
Cost-Effective Infrastructure:
Expanding into open land often requires new infrastructure, including roads, sewage, and utilities, which can be costly. Utilising existing infrastructure in already developed areas is more economical and minimizes the strain on community resources.
Social Advantages
Enhanced Accessibility:
Concentrated town development can lead to better access to amenities and services such as schools, hospitals, and cultural institutions. This proximity enhances the quality of life and reduces travel time for residents.
Community and Connectivity:
Taller buildings in town areas can foster a greater sense of community and connectivity. Shared spaces such as rooftop gardens, gyms, and common areas encourage social interaction and community building.
Sustainability
Energy Efficiency:
Modern tall buildings are often designed with energy efficiency in mind, incorporating green technologies such as solar panels, energy-efficient windows, and advanced HVAC systems. This makes them more sustainable in the long run compared to single-family homes spread across large areas.
Reduction in Heat Islands:
While high-density development can contribute to heat islands, strategic planning and the inclusion of green spaces and rooftops can mitigate these effects. Sprawling developments on open land can exacerbate heat island effects due to increased roads and pavements and reduced vegetation.
Policy and Planning
Smart Growth Principles:
Building upwards aligns with smart growth principles, which advocate for sustainable town development. This approach encourages mixed-use development, walkability, and public transport use, leading to a more livable and resilient town.
Regeneration:
Developing taller buildings on previously used land can revitalise underutilised or blighted town areas, bringing new life and economic opportunities to neighbourhoods in need of investment.
Conclusion
Building taller buildings on previously developed land presents a more sustainable, economical, and socially beneficial alternative to expanding into open land. By making the most of existing town spaces, our community can accommodate a growing population without sacrificing the natural environment or incurring the high costs associated with new infrastructure. This approach not only addresses immediate housing needs but also fosters long-term resilience and sustainability.
