Landmarks, built in full view of their owner.
SIRPI builds significant homes and institutions for Tamil Nadu's most discerning families and trusts — on a fully open book. You see and approve every rupee, we never take a hidden margin, and any saving comes out of padding, never out of the materials or the standard.

of your money we ever hold — you pay the costs directly
A veteran architect, on your side of the table.
Every SIRPI project is overseen by Ar. Ganapathy— a senior Madurai architect with three decades of practice. He represents your interest at every stage and, in all that time, has never taken a commission or a charge beyond an architect's fee.
The Hindu — "Proud to be Tamil"No commissions, ever
Never a kickback or a hidden charge — only a single, disclosed fee.
You hold the purse
You pay the actual cost of works directly. We manage the build; we never finance or touch your money.
3-year defect liability
Workmanship and material covered for three years — three times the usual one.
An open book, not a black box.
Most contracts are sealed. Ours is transparent by design — every cost vertical itemised, hidden mark-ups removed, and the saving made visible. Toggle the model and see where roughly a fifth of a conventional bill quietly disappears.
The same building · two ways to pay
Real cost of works + ≈27% hidden margin & paddingyou can't see.
Real cost of works + one honest, fixed fee — and you still pay ≈18% less.
You save ≈ 18% — net of our fee.
The management fee is already inside the 82% you pay — it replaces the hidden margin, it isn't added on top. The ≈18% saving is what's left after it.
Illustrative proportions — not client cost data.
Open-book, by design.
A sealed tender bundles contingency, risk mark-ups, variation claims and the builder's margin into one opaque price — roughly a quarter of the bill, invisible to you. We bill the actual, measured cost of worksinstead — paid by you directly, never financed by us — plus a single, fixed management fee for running the build. Every cost is itemised by vertical, auditable in real time and benchmarked across projects — and because our fee doesn't grow when costs do, our incentives stay aligned with yours.
Seven cost verticals, each itemised
From a wedding palace to an institutional campus.
Amohaa Palace, Kadambavanam and Thangam Grand among them — every one delivered on the same open book.
Every stage, on the record.
Scrub through the real construction of the TCE Men's Hostel. At each milestone, the open book is doing its quiet work — actuals-based billing, stage-gated recovery, premium materials, a final vertical-wise cost report.
Actuals-based billing begins — you pay for real quantities, not a padded lump sum.
≈ ₹81 lakh saved — about ≈ 18%— on the Men's Hostel.
An ≈ 18,000 sq ft hostel delivered against a conventional tender of ≈ ₹4.38 Cr, transparently and on the open-book model — with an ≈ ₹10 Cr hostel (ongoing) now underway.
Your whole programme, on one screen — audit-ready, always.
A single, auditable source of truth — campus / project / vertical-structured records with real-time dashboards, AI summaries and variance flagging.

A private conversation
Directly with a principal architect — under an NDA if you prefer. No call centre, no junior, no sales script.
02
A transparent, open-book proposal
Your indicative actual-cost ranges and our single fixed fee, in writing — with no obligation to proceed.
03
Single-point accountability
One principal owns your project from the first sketch to the final, reconciled cost report at handover.
