Green facades: coordinating systems, plants and maintenance
A green facade involves more than supplying plants. Location, wall construction and maintenance access determine what is practical over time. Compare the whole project, from design and fixings to the ongoing care of the planting.
Ground-rooted or wall-mounted?
Ground-rooted planting grows from a planting area beside the building and may be trained on suitable supports. Wall-mounted systems place planting modules directly on the facade. Space requirements, structure and water supply differ accordingly.
Have the available area assessed before choosing a system. A photograph of mature planting does not show how a newly installed facade will look at handover. Discuss plant development and the intended appearance separately.
Assess the existing facade first
Wall condition, insulation, fixing options and access all belong in the design. Plant supports should not be attached to arbitrary facade components without assessment. Windows, shutters, ventilation openings and maintenance areas must remain accessible.
Clarify who can authorise changes and which local requirements need consideration. Necessary facade repairs or additional structural assessments should be identifiable separately in the quote.
Match planting and water supply to the site
Sun exposure, wind, root space and intended height influence plant selection. Evergreen, flowering or seasonal planting preferences can be discussed, but do not replace a site assessment.
Irrigation, a water connection and drainage where needed form part of the overall design. Not every system needs the same equipment. Ask who will check the supply and how it will be managed during holidays or winter.
Compare installation and ongoing care
A price per square metre is meaningful only for comparable systems. A small accessible climbing support and a complex wall-mounted system may involve very different scopes.
| Area | Check in the quote |
|---|---|
| Design | Area, system choice and facade assessment |
| Structure | Supports, fixings and necessary preparation |
| Planting | Plants, growing spaces and condition at handover |
| Supply | Irrigation, connections and controls where required |
| Installation | Access, scaffolding or platform and finishing work |
| Maintenance | Pruning, inspections, replacement plants and recurring costs |
Plan maintenance access from the outset
Pruning and inspections must remain possible once plants have grown. Agree which areas will be kept clear and how specialists will reach higher parts of the facade. A maintenance contract is a separate service with a defined scope.
Distinguish establishment care, later maintenance and replacement of plants that fail. Set out responsibilities and conditions. Lasting complete coverage should not be promised without these arrangements.
Prepare your enquiry
State the location, approximate height and width, available ground space and intended appearance. Details of water supply, access and known facade works are useful. Technical fixing details can be clarified with the contractor.
Then compare equivalent system types and the maintenance included. Green roofs, ordinary garden planting and facade repairs remain separate services even when coordinated with this project.
Frequently asked questions
Is every facade suitable?
Condition, construction, fixing options and plant choice need to be assessed together. There is no universal answer for every building.
Is irrigation equipment always required?
Requirements vary with plants, root space and location. Ask for the needs of the proposed system to be explained.
Will the facade be fully green immediately?
That depends on the system and the supplied plants. Many solutions develop coverage as plants grow. Agree on the expected condition at handover.
Is future maintenance included?
Only to the extent expressly agreed. Establishment care, regular maintenance and plant replacements should be specified separately.
