Living wall FAQ
Frequently Asked Questions
Our living wall FAQ answers common questions about living walls and vertical gardens. Here you will find guidance on installation, structural requirements, irrigation systems, plant selection, and long term maintenance for both commercial and residential projects.
For Developers, Asset Owners, Hotels & Facilities Teams
Most engineered living wall systems weigh between 40–70kg per m², depending on the system selected. Masonry and concrete façades are typically suitable. Where required, we design timber or steel support structures to safely transfer load to the ground. Professional structural review is recommended for commercial installations.
Commercial living wall systems generally build out 90–150mm, excluding plant growth. This allows for irrigation, drainage, and root development while maintaining a streamlined façade profile.
Units should be positioned at least 150mm clear of vents and building services. Heating vents must extend beyond the planting line to prevent heat stress to foliage. We coordinate early with M&E teams to ensure compliance and long-term plant health.
Bespoke units can be fabricated to wrap corners or maintain continuous planting across façade changes. This ensures design continuity without compromising waterproofing or structural integrity.
Programme depends on scale and access. As a guide, an experienced team can install 10m² per day, with planting typically completed within a further day. Larger façades require access planning, which we manage as part of the installation strategy.
Yes. Free standing systems can be installed where connected to a purpose-built base or reservoir. These are commonly used in hospitality terraces, courtyards, and rooftop environments.
No, provided a protective membrane is installed correctly. Fixings are sealed using chemical grout to maintain waterproof integrity. Our systems are engineered to prevent moisture ingress and protect building fabric.
Run-off can drain into soft landscaping, French drains, or be directed via a concealed gutter system to a designated drainage point. Drainage is factored into design from the outset.
Microclimates are addressed through zoned irrigation systems and tailored plant selection. Automated irrigation can be divided into multiple zones to accommodate shade, wind exposure, and solar gain variations.
Plants typically perform for 3–10 years, depending on species and maintenance. Engineered systems have an expected lifespan of 10–20 years, subject to specification and ongoing care.
Maintenance depends on plant selection and system type.
Evergreen, texture-based planting schemes require less upkeep than intricate patterned designs. We recommend:
– Monthly inspections
– Quarterly horticultural visits
Well-designed systems reduce operational burden and long-term cost.
For Homeowners & Garden Professionals
House walls, courtyards, boundary walls, fence uprights, and balcony railings are all suitable, subject to structural review.
Yes. Indoor living walls require careful consideration of lighting, irrigation, airflow, and plant selection to ensure long-term performance.
Evergreen plants with a maximum growth height of 60cm perform best. Ground covers, small shrubs, grasses, and ferns are ideal. Limit deciduous or flowering varieties to around 15% to reduce seasonal gaps and maintenance demands.
Yes. Up-lighting, back-lighting, water features, decorative frames, and bespoke detailing can all be incorporated into the design.
Automated irrigation should run year-round and be adjusted seasonally. Nutrients can be added during the growing season. Smaller residential walls can be manually fed 2–3 times per year.
Most systems use P9 to P12 pot sizes, though some can accommodate plants up to 2 litres.
Soil-based systems use a blend of quality compost and coconut fibre. Alternatively, fine green roof substrate with approximately 80% inert and 20% organic material can be used.
Plant selection should reflect aspect and exposure. Automated irrigation systems can be zoned to accommodate differing moisture needs across the wall.
Plants can last 3–10 years or more, depending on care and selection. System lifespan ranges between 10–20 years.
