A dome is usually the structure a Delhi school, college, or institutional campus reaches for when it wants a genuine architectural centerpiece — over an atrium, entrance lobby, or library — rather than just functional coverage. It's a different engineering problem from a standard roof: a compression ring and tensioned membrane instead of a flat or barrel-vault form, which means structural sign-off and fabric choice both need more upfront thought.

Why Institutions Choose a Dome Form
- A rounded, column-light roof over an atrium or large indoor/semi-indoor space
- An architectural centerpiece structure that reads as intentional design, not just coverage
- Large-span coverage without interior supports blocking the space below
Dome vs. Other Large-Span Forms
A dome is one of several large-span options — which one fits depends on the space and how it's used:
| Best For | Span | Structural System | |
|---|---|---|---|
| Dome | Atriums, institutional centerpieces | 10m–50m diameter | Compression ring, tensioned membrane |
| Auditorium | School/college auditoriums, community halls | 20m–60m+ | Barrel-vault or saddle, acoustic/lighting engineered |
| Membrane | Large institutional roofs and facades | 15m–80m+ | Continuous tensioned membrane, saddle or hyperbolic paraboloid |
Typical Specifications
| Specification | Typical Range |
|---|---|
| Span / Size | 10m–50m diameter |
| Height / Clearance | 5m–15m |
| Structural Form | Dome — compression ring with tensioned membrane |
| Recommended Fabric | PTFE or PVDF |
| Foundation | Compression-ring foundation sized to the dome's diameter and load |
Structural Engineering for a Dome
Dome structures need careful structural engineering for the compression/tension balance across the curved form — the compression ring, cable, or frame support system is worked out during design, along with the dome's diameter and height relative to the surrounding building. This isn't something we bolt on after fabrication starts; it's part of the initial design conversation.
Natural Light and Fabric Choice
Natural light transmission is a real design lever for an institutional dome — a translucent fabric grade can bring daylight into the atrium or lobby below, cutting down on how much artificial lighting the space needs during the day. This is decided alongside the fabric-grade choice, not as a separate add-on.
Fire Safety and Certification
Public and institutional spaces — schools, colleges, community halls — often have their own fire safety and material certification requirements, separate from a purely residential or commercial project. We raise this during the design conversation so the right fabric grade and any required certification is confirmed upfront rather than discovered late.

| 2. Site Visit | Diameter, height, and surrounding structure confirmed on-site. |
| 3. Structural Design | Compression ring and support system engineered for the space, with sign-off before fabrication. |
| 4. Quote | A site-specific quote before fabrication begins. |
| 5. In-House Fabrication | Handled by our own team. |
| 6. Installation | Scheduled around the campus's academic calendar where possible. |
