A tensile structure in India typically costs ₹350 to ₹700 per sq ft before GST, covering the membrane, steel frame, fabrication and standard installation. Where a project lands in that range depends mainly on the fabric type and GSM, the span and frame, wind exposure and structure load, and how easy the site is to work on.
This guide is written by WhiteShed Solutions LLP, which designs, fabricates and installs tensile membrane structures from its workshop in Thane. It explains what moves the price, what a quotation should include and how to compare two quotes fairly.
Tensile structure price per sq ft at a glance
| Item | Indicative range or note |
|---|---|
| Tensile structures: car parking, terraces, canopies, walkways, pools, gazebos | ₹350 to ₹700 per sq ft before GST |
| GST | Charged on top of the quoted rate; the ranges on this page are before GST |
| Foundations and civil work | Often excluded; ask for them to be priced separately |
| Retractable pergola | From about ₹855 per sq ft before GST (see retractable pergola) |
| Retractable roofs | Quoted after a site visit, because the mechanism and frame vary by project (see retractable roofs) |
Ranges are indicative, based on WhiteShed’s published product pricing, and are not a quotation. The final price follows a site visit and drawings.
What drives tensile structure cost?
Fabric type, GSM and brand
The membrane is usually the biggest single cost variable. PVC-coated polyester is the most common fabric for commercial and residential work. A PVDF top coat adds dirt and UV resistance for exposed, visible roofs. PTFE-coated fibreglass is used on large permanent roofs at a higher cost. HDPE knitted shade net is a cheaper, shade-only option and is not waterproof. Heavier fabric (higher GSM) is chosen for larger spans and more exposed sites. On published WhiteShed projects we have used PVDF-coated fire-retardant fabrics from Sioen, Serge Ferrari and Mehler between 650 and 1,050 GSM. More in the tensile fabric guide.
Span, shape and number of columns
Cost per square foot tends to fall as the covered area grows, because design, fabrication and mobilisation are spread over more area. Larger spans also need heavier steel and cables, so a single long-span structure with few columns can cost more per square foot than a multi-column layout of the same area. See the types of tensile structures for how shape affects the frame.
Steel frame and coating
Mild steel (MS) frames are standard. On WhiteShed projects the steel receives one coat of epoxy primer and two coats of epoxy paint. Stainless steel or aluminium is sometimes specified for coastal or highly visible work, at a higher cost. The steel is fabricated in our structural fabrication workshop.
Wind exposure and structure load
A rooftop in a coastal city or a tall, open site sees higher wind uplift than a sheltered courtyard. Higher loads mean heavier sections, stronger connections and larger foundations, all of which show up in the price.
Site conditions and access
Foundation type, soil, existing slabs and access all affect installation. A terrace with no crane access usually costs more to execute than a ground-level car park with open access, even when the structure itself is the same.
What pushes cost up, by application
| Application | What usually moves the price |
|---|---|
| Car parking shed | Cantilever designs need larger foundations; many repeated bays lower the cost per bay |
| Terrace structure | Fixing to the slab or parapet, lifting materials up, wind at height |
| Entrance canopy | Feature forms, PVDF fabric, integrated lighting |
| Walkway cover | Route length, curves, and clear height at vehicle crossings |
| Swimming pool structure | Spans across the pool and coatings suited to a humid poolside |
| Gazebo | Small areas, so fixed design and installation costs weigh more per sq ft |
| Auditorium and seating roof | Large spans and tall masts or arches |
What should a tensile structure quotation include?
- Fabric make, type and GSM
- Steel sections, connections and the coating system
- Design and structural checks
- Foundations and civil work: included or excluded
- Drainage: gutters, downpipes and where water goes
- Transport, lifting and installation
- Warranty terms for fabric and workmanship
- GST and the payment stages
Ask every vendor to confirm in writing what is included and excluded before you compare. Our checklist for comparing tensile structure quotations goes line by line.
Hidden costs to watch for
- Foundation and civil work, if not scoped by the tensile contractor
- Drainage changes for large roofs
- Site-specific wind checks for tall or exposed installations
- Crane hire and transport to difficult sites
- Maintenance and re-tensioning after installation
Does warranty affect the price?
Yes, through the fabric. Higher-GSM, PVDF-coated fabrics cost more and support longer warranty terms. WhiteShed offers warranties of up to 15+ years, depending on the structure requirement and fabric GSM, and the terms are written into each proposal.
FAQs
Is tensile structure cost calculated per square foot?
Usually, yes: quotations are presented per square foot of covered area. Complex architectural forms are sometimes priced as a lump sum because of the custom engineering involved.
Does the price include installation?
For standard applications it usually does, but foundations, drainage changes and site-specific civil work are often excluded. Confirm this in writing.
Is PTFE more expensive than PVC?
Yes, upfront. PTFE is chosen for large, long-life roofs where re-membraning later would be difficult; PVC-coated polyester suits most car parking, terrace and canopy work.
Is the cost the same across India?
Fabric and steel costs are broadly similar; transport, travel and site logistics change with location. WhiteShed delivers from its Thane workshop to projects across Maharashtra, Gujarat, Rajasthan, Uttar Pradesh, Kerala, Kolkata and Kathmandu. See where we work.
