Efforts like this help to adjust the balance in the relationship we have with the natural environment, from nonchalance to comprehension, respect and value.
Architects have the power to integrate and increase the biodiversity throughout all schemes. This can lead to numerous environmental and societal benefits with green roofs, vertical gardens, and wildlife-considerate buildings that enhance urban ecosystems. These features help conserve local flora and fauna, improve air quality, reduce urban heat island effects, and promote healthier and happier communities. Designing with biodiversity can create aesthetically pleasing, vibrant urban spaces that improve the overall quality of life for residents and visitors.
Stricter planning regulations can help combat the growing issue of habitat loss. Since 2021, architects have been following the Biodiversity Net Gain (BNG) policy under the Environment Act 2021 and it was only in February 2024 that this applied to all new developments. However, there has been debate on whether these policies go far enough, with the Environmental Act only laying out the following:
“The biodiversity gain objective is met in relation to development for which planning permission is granted if the biodiversity value attributable to the development exceeds the pre-development biodiversity value of the onsite habitat by at least the relevant percentage.”
“The relevant percentage is 10%”
If the existing, pre-developed site had a total biodiversity value of 0%, then the developer would only need to increase this to 10% to satisfy this policy. Yes, there is an improvement to the site’s green performance, however, the current policy does not encourage best practice to optimise the opportunity.
