The Glasgow Institute of Architects kicked off its first sustainability event of the year with a compelling discussion led by ERZ Landscape Architects. With a focus on biodiversity, ERZ discussed how landscape architecture plays a pivotal role in shaping spaces that go beyond sustainability to become truly nature-positive.

One of the key messages from ERZ was clear: landscape architects should be brought into the conversation early. Too often, biodiversity is treated as an afterthought or just a requirement for planning approval. But, as Felicity Steers, Director at ERZ, pointed out, when landscape architects are involved from the start, they can contribute valuable insights into sighting, water management, and planting strategies. This early collaboration leads to more thoughtful, functional, and biodiverse designs, maximising the potential of any site.

ERZ showcased several inspiring examples of how landscape architecture can transform spaces for both people and the environment. Take The Prince and Princess of Wales Hospice, for example, where a peaceful garden offers residents and families a place to relax and improve their mental well-being. Or the Maryhill North housing development in Glasgow, where a landscape-led approach integrates biodiversity into the heart of a new community. And in Lochgilphead, a sensitive waterfront intervention has revitalised public space while providing a new connection to the water.

These projects highlight the power of landscape architecture to enhance human health, foster community, and support nature; all through thoughtful, early-stage design.

However, the road to successful biodiversity integration isn’t always easy. ERZ shared the ongoing struggle of budget cuts on projects, with landscape elements often seen as non-essential. In addition to this, another barrier is the lack of alignment between engineers and landscape architects: particularly around Sustainable Urban Drainage Systems (SUDS). Too often, engineers and SEPA continue to favour traditional drainage systems over more biodiverse, natural solutions. This preference for drains instead of biodiverse natural drainage systems (such as wetlands and ponds) not only misses an opportunity to enhance biodiversity but also doesn’t offer the same long-term ecological benefits.

To truly drive change, we need to facilitate more discussions with engineers and other stakeholders to ensure that blue and green solutions are prioritised alongside conventional infrastructure.

With the introduction of National Planning Framework 4 (NPF4) and its biodiversity requirements, the conversation around sustainability is shifting. The integration of nature-positive designs is no longer optional but essential for future-proofing our built environment. As Felicity Steers put it: “We want to leave the world a better place, not just a sustained one.” Architects have a unique opportunity to lead the way in integrating biodiversity into every stage of design.

Biodiversity isn’t just a trend; it’s a critical component of creating spaces that work for both people and the planet. Let’s ensure that landscape architects are involved from the start and that green solutions lead the way forward.

Actions for Architects:

Involve landscape architects early in the design process to ensure better, more sustainable outcomes.
Prioritise biodiversity and natural drainage solutions like SUDS that benefit both people and ecosystems.
Advocate for green and blue spaces as core elements of any project, not add-ons.
Facilitate more collaboration with engineers and stakeholders to push for biodiverse drainage systems over traditional methods.
Stay informed about NPF4 biodiversity requirements and the evolving policies shaping the future of design.

GIA Next Steps:

Following this event, the GIA decided to improve biodiversity engagement in all areas. This included inviting industry landscaping and biodiversity professionals to join the judging panels for the GIA Student Awards 2025. This is the first step in integrating biodiversity into the architectural education curriculum.
