Project Overview
daylit membrane roof
over the central court
Ekra Decor’s archive photographs show a tensioned fabric roof over the central court of Vasant Square, an operating shopping mall in Vasant Kunj, New Delhi, on Mehrauli–Mahipalpur Road.
The clientThe mall is developed and owned by Sun City Projects Pvt. Ltd. Ekra Decor was engaged to roof its central retail court — the open volume the escalators rise through, ringed by shopfronts on four levels — so the space below reads as a bright indoor street rather than a covered pit.
What it coversThe roof spans about 55,923 sq ft (≈5,196 m²) on radiating steel ribs beneath a translucent tensioned membrane. It carries no intermediate columns, so sightlines across the court and up to the upper-level shopfronts stay open, and the membrane diffuses direct sun into even daylight instead of hard shadow and glare on the trading floor.
The settingFour levels of retail frontage are visible beneath the roof in the photographs — Bata, Mochi, Peter England, Pantaloons, Big Bazaar and a Bagrry’s café unit are all identifiable on the signage — which places the structure directly over active retail space, not a service or back-of-house area.
The programmeThe work took roughly 90 days. The mall stayed open and trading throughout, so steel fabrication and membrane welding were done off-site and lifts, connections and tensioning over the court were sequenced around mall hours and the tenants already operating below.
The recordTwelve photographs from Ekra Decor’s own project archive appear in the gallery below — the membrane geometry, the mast-and-cable structure, the perimeter edge beam and the roof seen from several levels of the court.
Project Highlights
Project highlights
Daylit central court
A translucent membrane roof over the court brings daylight deep into the mall while diffusing direct sun into even light on the trading floor.
No columns in the court
Radiating steel ribs span the full opening with no intermediate supports, so sightlines across the court and up to the upper-level shopfronts stay clear.
~55,923 sq ft roofed
Roughly 55,923 sq ft (≈5,196 m²) of tensioned fabric membrane on a galvanised steel frame over the escalator court.
Built for the developer
Commissioned by Sun City Projects Pvt. Ltd., the company that developed and owns Vasant Square Mall.
Mall stayed open
Steel and membrane were fabricated off-site and lifts and tensioning were sequenced around mall hours, so tenants below kept trading throughout.
Delivered in ~90 days
Design, off-site fabrication and installation over the live court completed in roughly 90 days.

Common Questions
About this project & building something similar
What type of structure is this?
Ekra Decor's project records describe this installation as a mall atrium / courtyard tensile roof.
Where is this project located?
Vasant Kunj, New Delhi.
How large is the covered area?
About 55,923 sq ft (≈5,196 m²) of membrane roof, per Ekra Decor's project records.
How long did this project take to build?
Roughly 90 days from start to finish, per Ekra Decor's project records — off-site steel fabrication and workshop membrane welding overlapped with on-site work so the trading mall below stayed open throughout.
Who was this project built for?
Sun City Projects Pvt. Ltd., the developer of Vasant Square Mall.
Are there real photographs of this project?
Yes — 12 photographs from Ekra Decor's own project archive appear in the gallery above, not a stock or illustrative image.
Can Ekra Decor build something similar for my site?
Yes — every project starts with a site survey and a custom 3D design tailored to your space, not a fixed template. Get in touch to discuss a similar structure for your own site.
What membrane material would a structure like this be built in?
The choice depends on span, climate and intended lifespan. PVC-coated polyester is the most cost-effective option, with a 10–15 year service life. PVDF-coated polyester adds a self-cleaning top layer and pushes that to 15–20 years. PTFE-coated fibreglass is a permanent, non-combustible membrane with a life measured in decades, and ETFE film is used where an ultra-light, highly transparent roof is needed.
Is the structure engineered to Indian standards?
Yes. Wind, rain and — where relevant — snow and seismic loads are analysed to the applicable IS codes, and the steelwork is designed to IS 800. The membrane is form-found so its stresses stay balanced in double curvature, and the foundations are sized against uplift and overturning rather than gravity alone — the governing case for a lightweight tensile roof.
What warranty and documentation come with the structure?
Up to a 10-year written warranty on the membrane, plus as-built drawings, original mill certificates for the membrane and steel, a structural stability certificate and an operation & maintenance manual on handover. An annual maintenance contract covering inspection and re-tensioning is optional.
How much maintenance does a tensile structure need?
Very little — a periodic wash to remove surface dirt, and an annual check of cable tension and bolt torque. PVDF and PTFE membranes are largely self-cleaning, so rain keeps them looking new. We can carry this out under an annual maintenance contract if you prefer.
