What's included in the fee

Standalone vs bundled

Standalone structural design (you hire SE separately): ₹8-18/sq ft as above. Bundled with architectural package (Homeli): included free in the ₹95-180/sq ft architectural fee. Most clients prefer bundled — single accountability, no coordination, no separate fees.

Frequently asked

How much does structural design cost in Chennai 2026?
₹8-18 per sq ft of built area depending on project complexity. Single floor ₹8-12/sq ft, G+1 ₹10-15, G+2/G+3 ₹12-18, villa with basement ₹15-22. For a typical 1,500 sq ft G+1: ₹15,000-22,500. Bundled into Homeli's full architectural package at no additional cost.
Is structural design more expensive for taller buildings?
Yes — more floors mean larger columns, larger beams, more reinforcement, more complex load analysis (especially lateral loads from wind and seismic). A G+2 structural design is roughly 25-40% more expensive than the same area as G+1 due to design complexity, not just floor count.
What affects structural design cost the most?
(1) Number of floors — taller is more complex. (2) Plot soil condition — poor soil means specialised foundations. (3) Plot constraints — irregular shapes need more design effort. (4) Architectural complexity — long spans, cantilevers, double-heights all increase structural design effort. (5) Site location — coastal humidity and seismic-zone effects add design considerations.
Can I save money by skipping structural design?
No — and trying is dangerous. Structural design fees (₹15,000-50,000 for typical residential) are tiny compared to construction cost (₹25-50 lakh). Skipping leads to either wasted material (over-built, ₹1-3 lakh extra) or structural failure (catastrophic). Always get proper structural design done.
Why do some firms charge more for structural design?
Pricing variation comes from: (1) standalone vs bundled (bundled is usually cheaper effectively), (2) engineer's experience and qualification, (3) project complexity, (4) regional rates. Lowest-cost options (₹4-6/sq ft) often skip critical analysis or use generic templates — risky. Stick with the ₹8-18 range from credible firms with verifiable credentials.
Are construction supervision visits included in structural design fee?
Usually 1-2 critical visits are bundled (foundation pour, slab pour). Additional supervision is charged separately at ₹300-500/visit. Homeli's package includes the critical structural visits at no extra cost; full-time site supervision is a separate construction-management service.
