Notes & assumptions
  • **Samagra Shiksha + RTE 2009** norms: minimum classroom area 30 m² for primary (30 students max), 1 m²/student minimum. Default 5 × 6 m gives 30 m² for 30 students. Verandah ≥ 2 m wide is mandatory for South India / monsoon regions; 1.5 m acceptable for arid zones.
  • Standard block configuration: classrooms in a row, single-loaded along front verandah (sun + ventilation on back wall). Toilet block at one end (separate boys + girls + accessible WC + wash area). Storage / staff room can be added at the other end.
  • Floor-to-ceiling height ≥ 3.0 m per NBC 2016 Part 4 for assembly buildings (schools). Default 3.3 m gives extra headroom + better cross-ventilation in monsoon-prone areas.
  • RCC frame: 300 × 300 mm columns at 6 m c/c (one between each classroom + corners), 230 × 300 mm plinth beam, 230 × 230 mm tie beam at lintel level, 150 mm roof slab with 110 kg/m³ steel.
  • **Cost target** for 4-room standard block (24 × 7 m, 168 m² total) with toilet + all finishes: approximately **₹20-28 lakh** per CPWD DSR 2023 (excluding GST + contractor profit). 6-room: ₹28-38 lakh. State-PWD rates 8-15 % below DSR.
  • Samagra Shiksha funding norms (2026): ₹14.2 lakh per classroom (primary, urban) / ₹12.0 lakh (primary, rural). Higher for upper-primary + secondary. Funds also cover toilet, electrification, drinking water, library room.
  • Excludes: blackboard (200 × 90 cm each, ₹3-4K per room), tube-light + fan + switchboard (₹15-20K per room), ceiling fans 4 nos per room (₹8-10K), drinking water filter (₹15-25K), accessible ramp at front entrance per RTE (₹8-15K), compound wall (use [Boundary Wall](/boq/boundary-wall)), playground levelling (₹2-5L), boundary gate.

The **School Classroom Block (4-6 rooms)** is the workhorse of Indian school construction — every Sarva Shiksha Abhiyan / Samagra Shiksha tender, every state Education Department building scheme, every CSR-funded school project builds blocks of 4-6 classrooms along a covered verandah. Per **Samagra Shiksha + RTE 2009 + NBC 2016 Part 4 (Assembly Buildings)**, each classroom must be ≥ 30 m² (1 m²/student × 30 students), ≥ 3.0 m floor-to-ceiling, with a ≥ 2 m wide front verandah, and separate boys + girls toilet at one end. Construction is RCC framed (isolated footings + 300×300 mm columns + 150 mm roof slab) with 230 mm brick infill walls and ceramic tile flooring. This Builder generates the complete BOQ from your dimensions.

Samagra Shiksha funding + per-classroom cost benchmark

Under Samagra Shiksha (the umbrella programme that merged SSA + RMSA + Teacher Education), Government of India funds **₹14.2 lakh per classroom (urban primary) / ₹12.0 lakh (rural primary)** for the basic civil shell + toilet + drinking water + electrification + basic furniture. Upper-primary classrooms get ₹16.5L (urban) / ₹13.8L (rural). Higher secondary blocks get ₹22-28L per room. The funding norms are reviewed annually by MoE. A 4-classroom rural primary block thus has a sanctioned cost of ₹12 × 4 = ₹48 lakh (incl. toilet block ₹6L + ancillaries ₹6L). The CPWD DSR 2023 BOQ from this Builder typically comes to ₹20-28 lakh for the basic civil shell — well within the sanctioned amount, leaving headroom for furniture, fans, drinking water filter, and ramp.

RTE-mandated minimum specifications

The **Right to Education Act 2009 + Samagra Shiksha framework** specify these MINIMUM standards for any school classroom block: (1) **Classroom area** ≥ 30 m² for primary (1 m²/student × 30); ≥ 40 m² for upper primary (≥ 1 m²/student × 40). (2) **Floor-to-ceiling height** ≥ 3.0 m (NBC 2016 Part 4 / Cl. 4.1). (3) **Ventilation** ≥ 20% of floor area as openable window. (4) **Verandah** mandatory for monsoon protection, ≥ 1.5 m wide. (5) **Toilets** separate boys + girls + accessible (CWSN-friendly), 1:40 boys / 1:25 girls minimum ratio. (6) **Drinking water** + handwash facility within 30 m of every classroom. (7) **Ramp** at front entry mandatory for accessibility. (8) **Boundary wall** + secured gate for safety. (9) **Playground** + assembly area (size flexes per land). Use the [Toilet Block](/boq/toilet-block) + [Boundary Wall](/boq/boundary-wall) templates for ancillaries.

Frequently asked questions
**CPWD DSR 2023 basis**: ₹5-7 lakh per classroom for the basic civil shell only (RCC + brick + plaster + paint + floor + door + windows). **Samagra Shiksha sanctioned cost** (covers civil + toilet + drinking water + electrical + basic furniture): ₹12-16.5 lakh per classroom depending on rural/urban + level. Private CSR-funded schools typically spend ₹15-25 lakh per classroom for premium finishes.
