How to use this calculator
Enter wall area in sq ft, then select location, system type, and whether irrigation hardware and annual AMC belong in the planning scope. The result panel shows an installation range and optional AMC band. Use it to compare assumptions across bids, not as fixed contract pricing. For wider landscape programmes that include green walls as one module, start with the landscaping cost calculator; for per sq ft bands and BOQ line-item logic, read the landscaping cost guide.

Green wall and vertical planting references
Living wall substrates, indoor atrium planting, and wall-mounted irrigation contexts that shape mounting structure, drainage, and maintenance access on commercial sites.
What drives vertical garden cost per sq ft
Green wall cost is built from system and interface line items, not wall area alone. Each calculator input maps to distinct unit bases on commercial BOQs:
- Panel type separates living walls, preserved moss panels, and artificial panels because substrate depth, plant density, and establishment care differ. See the vertical garden cost guide for procurement drivers by system.
- Mounting structure and drainage interfaces cover anchoring, waterproofing coordination, and runoff management before panels or modules are fixed.
- Irrigation on vertical surfaces needs emitters, filtration, controller placement, and zoning without compromising the wall below. Refine irrigation totals with the irrigation cost calculator.
- Indoor versus outdoor location affects MEP coordination, humidity control, and species or panel selection for indoor plantation and lobby programmes.
- Where vertical planting shares podium or terrace scope, align deck assumptions with the terrace and podium gardens service page and terrace garden calculator.
Site constraints that change the range
Calculator ranges assume typical commercial inputs, but final BOQ shifts when structural allowances, waterproofing warranty boundaries, access for night works, or phasing change. Lobby green walls on hotel programmes often need earlier visual maturity than corporate atria, affecting container sizes and establishment risk. Architect-led packages carry tighter handover and FM documentation requirements. Wind exposure on outdoor facades affects species selection and sub-irrigation assumptions. Review BOQ clarity using the BOQ format guide before locking specifications.
From calculator output to BOQ qualification
Share calculator inputs and range when you request assessment. We align structural support, drainage approach, irrigation hardware, panel or plant specification, and FM handover documentation to your drawings before BOQ release. Compare contractor bids on the same specification level using the quotation comparison checklist. Where deck or terrace modules share the scope, test stack assumptions separately from wall area with the terrace garden calculator.
Maintenance and AMC after handover
Build BOQ and post-handover AMC are separate procurement decisions. Living walls need emitter cleaning, seasonal irrigation adjustments, and plant replacement within scoped allowances, with extra attention through the first monsoon. Moss and artificial systems still need scheduled cleaning and panel checks. Scope annual contracts with the AMC calculator and review landscape maintenance service boundaries. Handover documentation covers valve charts, irrigation schedules, and O&M notes for FM teams.
Frequently asked questions
- What does the vertical garden cost calculator estimate?
- The tool returns an indicative installation range from wall area in sq ft, location (indoor or outdoor), system type (living, preserved moss, or artificial panel), and whether irrigation hardware and annual AMC are included. The result panel shows install and optional AMC bands so you can test per sq ft assumptions before BOQ release.
- Is calculator output the same as final contract pricing?
- No. Calculator bands are planning ranges, not contract rates. Signed pricing follows site survey, confirmed structural support, panel type and plant density, irrigation and drainage interfaces, maintenance access, and a written BOQ with explicit inclusions and exclusions for procurement review.
- Which inputs change vertical garden cost per sq ft the most?
- Panel type (living, preserved moss, or artificial) usually moves the per sq ft band more than wall area. Irrigation hardware, structural support and anchoring, maintenance access, and optional annual AMC each shift totals independently. Indoor MEP coordination and outdoor exposure can add scope beyond area-only assumptions.
- When should I request a site assessment after using the calculator?
- Request assessment once you have approximate wall area, a shortlist of system types, and known structural or waterproofing constraints. Priority rises when green walls tie to hotel lobby openings, corporate atrium handover, or architect-led packages with FM documentation requirements. Share calculator outputs so assumptions align to drawings before BOQ release.
- How does this calculator relate to the cost guide and related services?
- The cost guide explains BOQ structure and commercial landscaping bands. Indoor plantation and terrace garden service pages cover scope, QA hold points, and handover documentation. This calculator tests wall-module assumptions for vertical-dominant scope. Use the landscaping cost calculator when green walls sit inside a wider landscape programme.
Next step
Vertical system BOQs compare fairly only when mounting structure, drainage approach, irrigation hardware, and maintenance scope are written clearly. Once you have a planning range, request a site assessment so we align assumptions to structural allowances, waterproofing interfaces, and FM handover requirements.
