# Wendy Allen Designs

Wendy Allen Designs is a specialist garden consultancy based in London offering expert advice on sustainable, climate-resilient garden design. The business focuses specifically on rain gardens, rain planters, biodiverse sustainable drainage systems (SuDS) and green roofs—innovative approaches that manage water runoff whilst supporting biodiversity.

Wendy Allen works with diverse clients including schools, private homeowners, and organisations seeking to implement nature-based solutions for flood resilience and environmental benefit. Her expertise addresses the growing need for gardens that work with climate change rather than against it, combining practical drainage solutions with ecological design principles.

What distinguishes this consultancy is its singular focus on water-smart garden design and sustainability. Rather than offering general garden design services, Wendy specialises deeply in rain gardens and SuDS applications—often overlooked by mainstream landscape architects. This specialism extends to education; the business actively delivers training workshops and lectures, positioning Wendy as a thought leader in sustainable drainage and climate-adaptive gardening.

The portfolio demonstrates real-world applications from school installations to show gardens, whilst the "crazy downpipes" concept reveals creative, artistic approaches to functional drainage. This combination of rigorous environmental knowledge and imaginative design thinking sets the practice apart. For clients concerned with flooding, water management, biodiversity, or simply wanting gardens with purpose, Wendy Allen Designs provides specialist knowledge unavailable from generalist designers.
